Validate European VAT number

You can verify the validity of a VAT number issued by any European Union Member State by by using this library. This lib is basically calling web service provided by VIES (at http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl) for VAT number validation.

What is a VAT number?

A value added tax identification number or VAT identification number (VATIN) is an identifier used in many countries, including the countries of the European Union, for value added tax purposes.

Get started

npm install validate-vat

In your code

var validate = require('validate-vat');
validate(countryCode, vatNumber, callback)

Example

var validate = require('validate-vat');
validate( 'xx',  'xxxxxxx',  function(err, validationInfo) {
    console.log(validationInfo);
});

Returns

when valid

{
  countryCode: 'xx',
  vatNumber: 'xxxxxxxxx',
  requestDate: '2013-11-22+01:00',
  valid: true,
  name: 'company name',
  address: 'company address'
}

when invalid

{
  countryCode: 'xx',
  vatNumber: 'xxxxxxxxxx',
  requestDate: '2013-11-22+01:00',
  valid: false,
  name: '---',
  address: '---'
}

possible error messages

  'The provided CountryCode is invalid or the VAT number is empty'
  'The VIES VAT service is unavailable, please try again later'
  'The VAT database of the requested member country is unavailable, please try again later'
  'The request to VAT database of the requested member country has timed out, please try again later'

Change Log

####0.3.1 Wrap field parse in a try catch block when it can not parse a soap message. The soap message will be attached to the error object for furthur investigation.

####0.3.0 - 05/Dec/2013 Instead of var validate = require('validate-vat').validate , you should call `var validate = require('validate-vat)' This will break your code, so update all the usages if you want to use this version
