About this Repo

This repository contains json files that programatically describe how to detect, validate, and decode the following types of tracking numbers:

JSON Format

  • couriers/*.json - identifies the standard couriers that might send mail

    • Each courier is defined by json hash with the following keys

      • name - Identifies the courier
      • courier_code - short code to identify the courier. Alphanumeric only, no spaces.
      • tracking_numbers - an array of possible tracking number formats for this courier

    • Each tracking number type is defined by a json hash with the following keys:

      • name - A name to identify this type of tracking number. Usually includes the carrier in the name, i.e. FedExGround

      • regex - A pcre compatible regular expression that identifies the tracking number regardless of spaces in-between characters.

        Every regex must contain the named groups SerialNumber and CheckDigit and depending on the tracking number can optionally contain the following common attributes:

        • ServiceType: indicating the type of delivery service
        • ShipperId: indicating the shipper id
        • PackageId: indicating the package id
        • DestinationZip: indicating the destination zip code

      • validation - Specifies how the tracking number is validated

        • checksum: if the tracking number has a checksum, include a checksum key with the details.
          • name: specifies the algorithm. Supported algorithms and parameters are mod10, mod7, s10, and sum_product_with_weightings_and_modulo. Look at existing examples for parameters.
          "validation": {
    "checksum": {
      "name": "mod10",
      "evens_multiplier": 1,
      "odds_multiplier": 2
    }
  }
        • serial_number_format: some tracking numbers require some modification of the group before validation. In the example below, the serial number needs a "91" prepended before validation unless the number starts with a 91, 92, 93, 94, or 95
        "serial_number_format": {
    "prepend_if": {
      "matches_regex": "^(?!9[1-5]).+",
      "content": "91"
    }
  }```

      • tracking_url - A url that we can use to find the tracking history for a particular tracking number. It assumes the tracking number can be entered using python style string formatting "www.courier.com?trackingnumber=%s".

      • test_numbers:

        • valid: an array of valid tracking numbers for testing
        • invalid: an array of invalid tracking numbers for testing

      • additional - (optional) further information relating to a named regex group can be specified. For instance, a lookup table for the ServiceType regex group, relating the two digit letter code with the type of service.

          "additional": [
      {
        "name": "Service Type",
        "regex_group_name": "ServiceType",
        "lookup": [
          {
            "matches": "01",
            "name": "UPS United States Next Day Air (Red)"
          },
          {
            "matches": "02",
            "name": "UPS United States Second Day Air (Blue)"
          }
        ]
      }
    ]

      Each hash in the lookup array should contain a key called matches or matces_regex, specifying how the value of regex_group_name should be compared.

I am creating a new library

If you are using this repo, it is most likely because you are writing a library to get information out of tracking numbers.

  1. Please check that your chosen programming language does not already have an implementation of a tracking number parser that uses these json files.
  2. If you are creating a new library, great! Open an issue and let us know. We're happy to help!

I found a bug or missing couriers.

  • Open an issue and specify the tracking numbers and courier service.
  • PRs: Feel free to modify any json file that does not specify it is auto-generated by a script. Run ./lint_json.sh to clean up and validate the json file (you may need jq or other dependencies).
