python-stdnum

A Python module to parse, validate and reformat standard numbers and codes in different formats. It contains a large collection of number formats.

Basically any number or code that has some validation mechanism available or some common formatting is eligible for inclusion in this library.

Common Interface

Most of the number format modules implement the following functions:

module.validate(number)

Validate the number and return a compact, consistent representation of the number or code. If the validation fails, an exception is raised that indicates the type of error.

Raises:

ValidationError – When the specified number is invalid

Returns:

str – A compact (canonical) representation of the number

module.is_valid(number)

Return either True or False depending on whether the passed number is in any supported and valid form and passes all embedded checks of the number. This function should never raise an exception.

Returns:

bool – True if validated, False otherwise

module.compact(number)

Return a compact representation of the number or code. This function generally does not do validation but may raise exceptions for wildly invalid numbers.

Returns:

str – The compacted number

module.format(number)

Return a formatted version of the number in the preferred format. This function generally expects to be passed a valid number or code and may raise exceptions for invalid numbers.

Returns:

str – A formatted number

The check digit modules generally also provide the following functions:

module.checksum(number)

Calculate the checksum over the provided number. This is generally a number that can be used to determine whether the provided number is valid. It depends on the algorithm which checksum is considered valid.

Returns:

int – A numeric checksum over the number

module.calc_check_digit(number)

Calculate the check digit that should be added to the number to make it valid.

Returns:

str – A check digit that can be appended

Apart from the above, the modules may add extra parsing, validation or conversion functions.

Helper functions and modules

exceptions

Collection of exceptions.

stdnum.get_cc_module(cc, name)

Find the country-specific named module.

Searches the stdnum collection of modules for a number format for a particular country. name may be an aliased name. For example:

>>> from stdnum import get_cc_module
>>> mod = get_cc_module('nl', 'vat')
>>> mod
<module 'stdnum.nl.btw' from '...'>
>>> mod.validate('004495445B01')
'004495445B01'

Will return None if no module could be found. The generic names that are currently in use:

• 'vat' for value added tax numbers

• 'businessid' for generic business identifiers (although some countries may have multiple)

• 'personalid' for generic personal identifiers (some countries may have multiple, especially for tax purposes)

• 'postal_code' for address postal codes
