php-iban

php-iban is a library for parsing, validating and generating IBAN (and IIBAN) bank account information in PHP.

All parts of an IBAN can be retrieved, including country code, checksum, BBAN, financial institution or bank code, account number, and where a fixed-length national system is in use, also branch/sort code. Legacy national checksums may also be retrieved, validated and correctly set, where available, whether they apply to the account number portion, bank and branch identifiers, part or all of the above. IBAN country codes can be converted in to ISO3166-1 alpha-2 and IANA formats, the parent IBAN country acting as registrar for dependent territories may be queried, the official national currency (ISO4217 alpha code format), central bank name and central bank URL may also be queried to ease integration. IBANs may be converted between human and machine representation. A database of example/test IBANs from different countries is included. Finally, highly accurate suggestions for originally intended input can be made when an incorrect IBAN is detected and is due to mistranscription error.

Tested on PHP versions:

Test on HHVM versions:

The parser was built using regular expressions to adapt the contents of the official IBAN registry available from SWIFT then manually modified for special cases such as errors and omissions in SWIFT's official specifications.

Various deficiencies in the initial adaptation have since been rectified, and the current version should be a fairly correct and reliable implementation.

Where appropriate, European Committee for Banking Standards (ECBS) recommendations have also been incorporated.

Please bear in mind that because the specification changes frequently, it may not be 100% up to date if a new version has been recently released - I do my best though. We are currently thought to be up to date with the May 2017 release, ie. PDF release #77.

Licensed under LGPL, it is free to use in commercial settings.

Installation via composer

If you use composer you can simply run composer require globalcitizen/php-iban to get going. Reportedly (and ) were done via composer.

(If you don't yet have composer and wish to install it in an insecure fashion (not recommended, but convenient) you can run curl -sS https://getcomposer.org/installer | php or wget -O- https://getcomposer.org/installer | php)

Then just add the following to your composer.json file:

// composer.json
{
    "require": {
        "globalcitizen/php-iban": "2.7.0"
    }
}

Then, you can install the new dependencies by running composer's update command from the directory where your composer.json file is located:

# install
$ php composer.phar install
# update
$ php composer.phar update globalcitizen/php-iban

# or you can simply execute composer command if you set it to
# your PATH environment variable
$ composer install
$ composer update globalcitizen/php-iban

You can see this library on Packagist.

Installation via git

For a regular install, use the git clone command:

# HTTP
$ git clone https://github.com/globalcitizen/php-iban.git
# SSH
$ git clone git@github.com:globalcitizen/php-iban.git

Installation via git submodule

Alternatively, to embed the php-iban library in your own git-managed repository at a specific revision number, such that it is possible to update the version in a predictable way while maintaining a larger system that depends upon its functionality:

# enter your project's git repo
$ cd my-existing-project-with-a-git-repo/
# select an appropriate place to create the php-iban subdir
$ cd lib/
# add php-iban as a submodule
$ git submodule add https://github.com/globalcitizen/php-iban.git
# commit new submodule
$ git commit -m 'Add php-iban submodule'

Then, when checking out git projects with submodules for the first time, normally you need to make a couple of extra steps:

# check out your project as normal
$ git clone git@your-server.com:your/project.git
# initialize submodules
$ git submodule init
# update submodules
$ git submodule update

To skip these steps, add the --recursive argument to git clone when checking out:

# check out your project, initialize and update all submodules
$ git clone --recursive git@your-server.com:your/project.git

If you later wish to your project to use a newer version of php-iban, run:

# fetch changes
$ git submodule update --remote php-iban
# commit
$ git commit -m 'Update php-iban submodule'

Manual installation

Fetch the latest release from our github releases page in either zip or tar.gz format.
Extract the library using your favourite archive utility, for example unzip filename.zip on Unix-like platforms.
Write your code to depend on the library based upon its relative location to your source code. For example if you wish to include php-iban from the parent directory's subdirectory libraries/php-iban you could use the following require_once() statement:

<?php
require_once(dirname(__FILE__) . '/../libraries/php-iban/php-iban.php');
# ... your code utilizing php-iban
?>

Comparison of PHP IBAN libraries

The following table compares php-iban to other PHP projects offering IBAN-related functionality, on the basis of general project information and the programming paradigms supported.

Notes:

Original download records for php-iban releases were hosted on Google Code and are now lost. Prior to establishing a release process on Github, we just expected that people would download the code... so we're really not sure how many installs exist, but this is a fair guess (~11k + composer installs + a little bit now and then).
php-iban also powers:
- adm-gravity-iban
- Azzana consulting's XML Solver for ISO20022
- basepa Payment Gateway for WooCommerce
- org.civicoop.ibanaccounts extension for CiviCoop
- commerce_sepa
- contao-haste_plus
- Dolibarr ERP & CRM (website)
- fieldwork: Web forms for cool people
- IBAN Validator for Drupal
- identity component for Laravel to check Spanish IDs
- lib-bankaccount (conversion to/from legacy German account format)
- PHP SEPA XML class (github)
- Project60 SEPA direct debit
- SEPA Payment Plugin for SubsGuru
- Silverstripe CMS module
- statement
- WooCommerce Germanized
- WooCommerce SEPA Payment Gateway
php-iban's author is an Australian born, Australia/New Zealand/German citizen based in mainland China, who has formerly also worked and banked in the US, UK, and many Asian countries.
The IsoCodes and SepaUtil's projects cover standards other than IBAN so their popularity should be considered in this light. (In essence, there is really only one directly competing library, Iban)

Now let's take a look at features.

	+	ISO	IANA	SEPA	₶	UO	MT	NC	₴	CB	H?	Registry
php-iban	✔	✔	✔	✔	✔	✔	✔	✔	✔	✔	✔	116: full, error-corrected CSV with open-source toolchain and documentation
Iban	✔*	✘	✘	✘	✘	✘	✘	✘	✘	✘	✘	54: partial, hardcoded, dubious origin
IsoCodes	✘	✘	✘	✘	✘	✘	✘	✘	✘	✘	✘	66: partial, hardcoded, dubious origin
SepaUtil's	✘	✘	✘	✘	✘	✘	✘	✘	✘	✘	✘	89: partial, hardcoded, dubious origin
Symfony	✘	✘	✘	✘	✘	✘	✘	✘	✘	✘	✘	95: partial, hardcoded, dubious origin

Note:

+ refers to the capacity to create checksum-accurate potential IBANs programatically. It is the author's opinion that generation features without IIBAN support (ie. authority) are of dubious use, except in one-off migrations. (See also NC, below)
ISO refers to the capacity to convert between IBAN country codes and ISO3166-1 alpha-2 country codes
IANA refers to the capacity to convert between IBAN country codes and IANA country codes (eg. 'GB' to '.uk' and vice versa)
SEPA refers to the ability to check whether a particular IBAN country is a member of the Single Euro Payments Area (SEPA)
₶ describes support for IIBAN, the open proposal for decentralized financial endpoint generation by private parties, such as crypto-currency exchanges, whilst maintaining compatibility with the emerging IBAN system. This system has been adopted by major cryptocurrency exchanges such as Kraken.
UO refers to support for unofficial countries whose IBAN formats have been published as in informal use by major financial institutions, but are not official SWIFT-published registry entries.
MT refers to mistranscription support: the capacity to automatically detect what the user probably meant when they make a transcription error on IBANs, such as those manually written or printed in confusing fonts, for instance writing 'L' instead of 'I' or '1', or vice versa.
NC refers to national checksum support: the capacity to verify and, where appropriate, set and extract the national checksum portion of a BBAN, for countries that offered pre-IBAN national checksum algorithms.
₴ refers to support for querying the official national currency's ISO4217 code for an IBAN country
CB refers to support for querying the name and URL of the central bank of an IBAN country
H? refers to support for input and output for the human, space-laden or presentation variant of an IBAN, ie. IBAN XXXX XXXX XXXX XXXX instead of XXXXXXXXXXXXXXXX - a lot more reasonable.

In short, while composer users have apparently lept on rival libraries (particularly Iban), probably due to the time it took us to integrate a composer file, those libraries are often either full-fledged web frameworks or burdensome in dependencies, less mature, fail to hat-tip to the free software foundation, do not support the procedural programming paradigm (for when AbstractProductClassMakerFactories just won't cut it), use data from dubious sources, tend to use licenses that are incompatible with certain commercial uses, and are frankly short on features.

So, fearless user ... choose php-iban: the ethical, functional, forward-looking, low-hassle library of choice for IBAN and IIBAN processing. Choose to win! ;)

Your Help Wanted

If you know the URL of national IBAN, BBAN or national checksum documentation from official sources, please let us know at issue #39 and issue #41.
Faroe Islands (FO) banks do not respond, neither does the Danish National Bank who referred me to them.
Luxembourg (LU) does not seem to conform to any single checksum system. While some IBAN do validate with reasonably common systems, others don't or use others. The suggestion that Luxembourg has a national checksum system may in fact be incorrect. We need some clarification here, hopefully someone can dig up an official statement.
Mauritania (MR) has a dual character checksum system but our example IBAN does not match MOD97-10 which would be the expected system. Previously the IBAN here was always fixed to '13' checksum digits, however as of registry v66 it is now dynamic, which suggests a changed or at least now nationally relaxed checksum system.
If you are willing to spend some time searching, we could do with some more test IBANs for most countries, especially smaller ones...

News: February 2016

Version 2.5.2 has been released.

Miscellaneous test library updated to validate example IBANs collection.

Version 2.5.1 has been released.

The 'Narodna banka Srbije' (908) bank in Serbia (RS) appears to have multiple live IBANs with broken national checksums, so we ignore all national checksums on accounts from that bank.

Version 2.5.0 has been released.

All users are encouraged to upgrade; this release is considered long term stable.
The following national checksum schemes added in the 2.4.x series are now included and well validated, while invalid assumptions have been removed:
Belgium (BE)
Spain (ES)
Monaco (MC)
France (FR)
Norway (NO)
Montenegro (ME)
Macedonia (MK)
Netherlands (NL) - including exception for INGB (ING Bank) who have dropped the original checksum
Portugal (PT)
Serbia (RS)
Slovenia (SI) - including exception for 01 (Bank of Slovenia) who do not honour checksums
Timor Lest (TL)
In addition, a library of test IBANs is being maintained under utils/example-ibans which has a good number of entries for a good number of countries already. This should simplify future research.
Documented ideas for the enhancement of the mistranscription error correction suggestion function.

Version 2.4.20 has been released.

Another bugfix release, based on further real world test IBANs from certain countries:
Remove Bosnia (BA) national checksum support

Version 2.4.19 has been released.

Another bugfix release, based on further real world test IBANs from certain countries:
Remove Finland (FI) national checksum support

Version 2.4.18 has been released.

Another bugfix release, based on further real world test IBANs from certain countries:
Remove Poland (PL) national checksum support

Version 2.4.17 has been released.

Bank of Slovenia (bank code 01 under Slovenia (SI)) does not implement the national checksum scheme, as a special case. An exception has been added to the Slovenia national checksum implementation.

Version 2.4.16 has been released.

Another bugfix release, based on further real world test IBANs from certain countries:
Remove Sweden (SE) national checksum support
I am now instituting a new rule that if national checksum support has not been tested on 10+ real world IBANs, preferably 20+ across a range of institutions, then it does not get committed. This means that small countries will be impossible to add until research is done beyond web-browsing.

Version 2.4.15 has been released.

The Netherlands (NL) bank 'INGB' no longer uses the national checksum scheme, and has been excepted from the check. This marks our first bank-specific checksum feature.

Version 2.4.14 has been released.

Another bugfix release, based on further real world test IBANs from certain countries:
Remove Estonia (EE) national checksum support
Remove Hungary (HU) national checksum support

Version 2.4.13 has been released.

This release is mostly about bugfixes, after spending a lot of time gathering IBANs online and using them for further testing.
Tunisia (TN) national checksum support has been removed, after additional testing with IBAN gathered from the internet it was found not to be correct. Perils of reverse-engineering!
A couple of other bugfixes:
The function iban_mistranscription_suggestions() now behaves correctly when passed loosely formatted IBAN-like strings
The checksum algorithm _verhoeff() which supports certain national checksum implementations now behaves correctly when passed invalid input

Version 2.4.12 has been released.

Tunisia (TN) national checksum support has been added.

Version 2.4.11 has been released.

It is now possible to query the central bank name and URL for each country, from new registry fields central_bank_url and central_bank_name, for example:
The central bank for New Caledonia (NC) is the 'Overseas Issuing Institute (Institut d'émission d'Outre-Mer)' and their URL is http://www.ieom.fr/
The central bank for the British Virgin Islands (BV) is 'The British Virgin Islands Financial Services Commission' and their URL is http://www.bvifsc.vg/
There is no central bank for the IIBAN (Internet) (AA).

Version 2.4.10 has been released.

New registry field currency_iso4217 stores the official currency of the country in ISO4217 alpha code format, for example:
The currency of Iceland (IS) is ISD
The currency of Saint-Pierre and Miquelon (PM) is EUR
The currency of Wallis and Futuna (WF) is XPF

Version 2.4.9 has been released.

New registry field parent_registrar stores the parent registrar IBAN country of an IBAN country, for example:
Åland Islands (AX) parent registrar is Finland (FI)
Faroe Islands (FO) parent registrar is Denmark (DK)
New Caledonia (NC) parent registrar is France (FR)

Version 2.4.8 has been released.

Version 2.4.0 has been released.

It is now possible to determine, verify and set the correct national checksums for some countries that offered a pre-IBAN national checksum algorithm via the new functions iban_{set|find|verify}_nationalchecksum() and their OO-wrapper equivalents. Presently Belgium (BE), France (FR) and Spain (ES) are supported. If you would like to see your country supported, please see issue #39 and issue #41.

Version 2.1.2 has been released. All known unofficial IBAN country codes are now integrated. As well as minor documentation updates and a shortening of the reported name of Kosovo, this version adds:

Ivory Coast (CI)
Madagascar (MG)
Mali (ML)
Mozambique (MZ)
Senegal (SN)
Ukraine (UA)

Version 2.1.1 has been released. Currently unofficial IBAN country codes are being integrated, and the process remains ongoing. This version adds:

Burkina Faso (BF)
Burundi (BI)
Cameroon (CM)
Cape Verde (CV)
Iran (IR)

Version 2.1.0 has been released.
Currently unofficial IBAN country codes are being integrated, and the process remains ongoing. A new flag has been created to check whether a country is an official, SWIFT-issued record or not. The following new countries have therefore been added.

Algeria (DZ)
Angola (AO)
Benin (BJ)

Note also that the IIBAN (AA) record has been marked unofficial, and features listed in docs/TODO have been migrated to Github issues and that file deleted.

Version 2.0.1 has been released. This is to celebrate real testing, composer support, as well as finally catching up with changes. This version should be up to date with all registry changes to the present, including changes or additions to the countries:

IIBAN (AA)
Brazil (BR)
Costa Rica (CR)
Kazakhstan (KZ)
Kosovo (XK)
Kuwait (KW)
Saint Barthelemy (BL)
Saint Lucia (LC)
Saint Martin (French Part) (MF)
Sao Tome and Principe (ST)
Timor Leste (TL)
Turkey (TR)

Version 1.6.0 has been released. This version features more registry corrections (newly added territories with faulty data, bad checksums in sample IBANs, etc.) as well as enhanced testing routines, extended documentation, and corrected documentation. All users are advised to upgrade. We now have automated test script execution with Travis CI, to provide additional robustness for all committed code. This took longer than expected as unfortunately I picked the exact time Travis broke their build logs - https://www.traviscistatus.com/incidents/fcllblkclgmb - to see what all the fuss was about... proving again that cloud computing is just great for breaking things unexpectedly. Because they want to hide things, there was literally no debug output whatsoever, and I was led to believe this was my fault. Fellow programmers, behold: it is the dawning of the age of the mystical fail.

Version 1.5.0 has been released. There are no code changes, but we now have http://packagist.org/ integration, hopefully this triggers it to start working. If you use packagist, you can now add the library to your project by just running composer require globalcitizen/php-iban (thanks to @acoulton for pointing the way)

Version 1.4.9 has been released using the new Github-based release process. Hopefully this provides a solid anchor point for those bundling the library with other software. We also have a contributed composer metadata file to ease integration. New IBAN registry URLs integrated. Removed old SVN tag/trunk structure.

News: July 2015

Corrected SWIFT URL to IBAN page. Emphasized mistranscription error support.

News: March 2015

Finally, google has killed code.google.com and we have migrated to Github! Once the old trunk/tag structure (lingering from svn) is cleaned up and this document translated from the old wiki format to markdown, a new version will be issued.

News: June 2014

Version 1.4.6 has been released:

Fixes for Jordan and Qatar. Turns out both of them have broken TXT registry entries, PDF entries differ and the PDF is the one to go for (familiar story).
Some further improvements.

Unfortunately, Google now requires code.google.com projects to use Google Drive. I tried to use Google Drive (sign up for a new account, jump through email hoops, get treated as a robot, learn stupid new touchy-feely-friendly interface, get meaningless error messages like 'Your sharing limit has been exceeded' (with 2x290KB files on a new account I was told to create) and lost patience entirely.

So for the moment, you'll just have to download using git, instead. I will migrate php-iban to Github shortly. Google really is a pain in the ass recently, what with all of this Google+ and Google Drive junk, ruining Picasa, ruining Sketchup by lack of attention, etc. What are they thinking?

News: March 2014

Version 1.4.5 has been released:

Addition of Jordan and Qatar
Minor changes to documentation and support scripts.

Version 1.4.4 has been released:

Fix SEPA status of Croatia (HR)
Subsqeuent SEPA status audit based upon https://en.wikipedia.org/wiki/Single_Euro_Payments_Area turned up some other status issues (this information is not contained within the official IBAN registry)
- Faroe Islands, Greenland, San Marino status fixed. Everything else apparently hunky dory.

The project source code repository has switched from svn (ugh) to git (yay!).

This should make future changes less painful.

News: September 2013

Version 1.4.3 has been released:

Add Aland Islands (AX), part of Finland (FI) that is only documented in the SEPA status field of Finland and does not have its own entry or mention elsewhere in the IBAN registry document.
- Consider but do not add either of the somewhat similar Canary Islands (CI) or Ceuta/Melilla (EA) - both minor territories of Spain (ES) - due to lack of any evidence of usage.
Fix SEPA status for Spain (ES), Finland (FI), Porgual (PT) due to registry values being mixed with free text.
- Document this and further issues with the official IBAN registry document, both as documentation in docs/COMEDY-OF-ERRORS and inline within the registry converter.
Update human country name of Palestine to better mirror current registry document ("State of" is dropped as is the reigning style, so simply "Palestine" is presented)
Updating an outstanding last modified date within the registry from the previous release

News: August 2013

Version 1.4.2 has been released:

Resolve issue #19: incorrect SEPA status of France/French territories due to a parser bug. (Thanks to the reporter)

Version 1.4.1 has been released:

Requests
- Attempts to intelligently calculate the 'account' portion of a BBAN based upon the (non-)presence of a branch ID and bank ID portion, by request (for Germany/Austria. Previously this was requested for the Netherlands, however this solution should fix results for everyone!)
- Add 'IIBAN' prefix removal support to machine format conversion function
- Add gmp disable flag ($__disable_iiban_gmp_extension=true;)
Silence warnings on some PHP engine configurations
Update Brazil record (minor)
No longer redistribute IBAN registry in .txt format
Improve inline documentation

News: June 2013

Version 1.4.1 is still being prepared, squashing some bugs and updating the registry ... meanwhile, it has come to my attention that we have been featured in the Code Candy blog! http://www.codecandies.com/2012/05/30/no-exceptions/ Hooray for the German sense of humour! Hahah.

News: March 2013

Version 1.4.0 has been released:

Resolves an issue reported affecting the last few versions when attempting to generate a correct checksum for a checksum-invalid IBAN.
Adds VERSION file, to include hard version information in source tree, by request.

News: February 2013

Version 1.3.9 has been released:

Resolves issue reported in 1.3.7 re-enables the more efficient PHP gmp library based checksum code (thanks to rpkamp)

Version 1.3.8 has been released:

An error in checksum processing for some IBANs using the new gmp library based MOD97 routine (only affects users with php-iban 1.3.7 and the PHP gmp library enabled) has been reported. As an immediate workaround 1.3.8 is being released with the following changes: ** Code from 1.3.6 ** Registry from 1.3.7

Version 1.3.7 has been released:

Added Brazil
Added two new French overseas territories
Reduced 'Moldova' to normalized short-form name
Large CPU efficiency improvement in IBAN validation routine (16x if PHP gmp extension is installed, 5x otherwise. Special thanks to algorithmic contributor Chris and to engineers everywhere upholding the Germanic tradition of precision and efficiency! Alas, I am but part-German, for shame...)
Minor internal/tool updates
Some comedy of errors additions

News: November 2012

Version 1.3.6 has been released:

Update IIBAN format for latest IETF draft.

News: October 2012

Version 1.3.5 has been released:

Correct lack of support for lower case alphabetic characters (ie. non ECBS-compliant) in human to machine format conversion function.

Version 1.3.4 has been released:

Add reference to the latest ECBS recommendations and include them in documentation.

Version 1.3.3 has been released:

Very minor efficiency improvement.

News: September 2012

Version 1.3.2 has been released:

Registry updates

News: September 2011

Version 1.1.2 has been released. This adds long open tags to the main library file in order to simplify deployment on many default PHP installations.

News: August 2011

Version 1.1.1 has been released. This fixes a typo in a function call in the new OO wrapper. Non OO users do not need to upgrade.

News: July 2011

Version 1.1.0 has been released. This version adds an object oriented wrapper library and related updates to documentation and test scripts. It is not critical for existing users to upgrade.

Version 1.0.0 has been released. This version includes the following changes:

Support for the SEPA flag ("Is this country a member of the Single Euro Payments Area?"), both in the registry and with a new function iban_country_is_sepa($iban_country)
Placeholder support for converting machine format IBAN to human format (simply adds a space every four characters) with the function iban_to_human_format($iban)
Fixed a series of domestic example issues in the registry file that had been imported from SWIFT's own broken IBAN registry
Normalised example fields in the registry to better facilitate use in automated contexts (Austria, Germany, etc.)
Updated test code
Added a significant amount of new documentation
*Reorganised file layout•
Moved to x.y.z format versioning and use of subversion 'tags' in conjunction with the 1.0.0 release.

Earlier in the month... Small maintenance release, not critical.

The split() function has been replaced with explode() to prevent warnings (or error on very new PHP engines)
Resolved an issue on PHP environments configured to display warnings would display a warning when an IBAN input to be validated did not include a prefix that was a valid IBAN country code. (Nobody should be running production PHP environments with such warnings enabled, anyway!)

News: June 2011

We are now well over 1000 downloads: not bad considering how specific this project is!
A new version has been released that fixes many important changes to the official registry, plus adds some new features.
- Add New French Territories (GF,GP,MQ,RE) Older versions of the specification did not include the GF,GP,MQ,RE French territories, only the PF,TF,YT,NC,PM,WF French territories. The new territories have now been added to the database.
- Add New Countries We welcome Bahrain (BH), Dominican Republic (DO), Khazakstan (KZ), United Arab Emirates (AE) to the database.
- Format/example updates There have apparently been some minor format/example changes, these have been rolled in to existing countries.
- Inclusion of altered IBAN_Registry.txt Errors and omissions have been found within the official IBAN_Registry.txt file, namely the exclusion of Khazakstan (KZ) and only partial information on Kuwait (KW), and errors in both of these countries' PDF specifications. This is SWIFT's fault: shame on them! I suspect they have changed staff recently. Anyway, a version of IBAN_Registry.txt with these problems solved is now distributed along with php-iban.
- Fix for Tunisia Strangely I visited Tunisia during the revolution in January this year. Sorry to the Tunisian people for getting their IBAN format wrong! TN59 + 20 digits is the correct format. This is now included in the new registry file.
- Fix for Albania The SWIFT format information was updated for Albania. (Did not affect validation, since this uses regular expressions which were already correct)
- Additional and revised documentation Further documentation has been added to the project.
- Automated IBAN_Registry.txt fix/conversion tool A new convert-registry tool has been added to the project that attempts to automatically normalise/fix problems with the official SWIFT .txt specification as much as possible. Note that this is not enough to get a good registry.txt file (the internal format used by php-iban) as SWIFT's .txt release excludes entire countries in the PDF specification. In addition, there are some errors in the PDF specification that need to be manually resolved at present. These can be seen resolved in the IBAN_Registry.txt file.

News: December 2009

*We now have a http://groups.google.com/group/php-iban-users mailing list. Feel free to post your feedback, queries or suggestions - we'd love to know how you are using the library. To date, the project has reached over 400 downloads and still going strong, with more than one new user per day - a pretty good showing for a specialised library!

*version 12 has been released. The registry file has been improved, partly as a result of user reports and partly as a result of issues uncovered while performing automated tests against version 11.

Corrected header row Two columns were not represented in the title (bban_length and iban_length). They have now been added.
Fixes to registry entries for French Territories (PF,TF,YT,NC,PM,WF) French territories are not explicitly included in the SWIFT specification textfile. They were duplicated from France according to an unstructured comments against that entry. Example IBANs were then made for illustrative purposes by simply modifying the country prefix without regenerating the checksums. The IBAN examples included for these territories should now be correct.
Gibraltar and Hungary (GI,HU) Fixed a bug where both territories had a superfluous colon appended to their regular expressions after initial document conversion, which was causing validation failures for all IBANs in those countries.
Mauritius (MU) Corrected IBAN length expectation from 31 to 30.
Sweden (SE) Example IBAN had been manually modified from IBAN specification example early in development and did not pass checksum. The IBAN official example has been restored.
Tunisia (TN) Corrected improper validation strings caused by a bug in initial document conversion (IBAN format-specifier to regular-expression conversion function).
