Package: identifier-tools
Library that helps working with different entity (legal person, entrepreneur, subject, etc.) identifier types.Purpose of this library is to validate string if it matches the identifier format and if possible calculate checksum
if it is correct for identifier.Identifier format checking is based on European Central Bank -List of national identifiersspreadsheet.Identifier format is extended by identifiers issued by Národná banka Slovenska -Národné voľby a špecifiká v projekte
AnaCredit.Currently supported identifiers for checksum calculation: IČO, IČO NI, LEI, NIČ, all available identifiers and their
format is listed in fileidentifier_tools/formats_constants.py.Identifier Tools library has support for ISO 7064 standard that is used to validate NIČ, LEI, IBAN among other things…

>>> verify_identifier_format(identifier_type="GEN_VAT_CD", identifier="1111")
True
>>> verify_national_identifier_country(country_code="SK", national_id_type="SK_ICO_CD")
TrueYou can list all available identifiers in a particular country. Some countries has multiple identifiers with
different priority, you can get the identifier rank as well:>>> from identifier_tools.formats import get_country_identifiers, get_identifier_rank
>>> get_country_identifiers("DE")
[(1, 'DE_TRD_RGSTR_CD'), (2, 'DE_VAT_CD'), (3, 'DE_TAX_CD'), (4, 'DE_NOTAP_CD')]
>>> get_identifier_rank("DE_TAX_CD")
3If you want to manually verify the identifier, it is possible to find a link provided by ECB:>>> from identifier_tools.mappers import get_verification_register
>>> get_verification_register('SK_ICO_CD')
'https://rpo.statistics.sk/rpo'
>>> get_verification_register('US_EIN_CD')

used for implementation, so we can reference to it.Clone a repository locally and make sure you work in your own branch and once you are happy with the functionality
create pull request. All new code should be covered with tests. We try to use test driven development for the project.If you find a bug feel free to create an issue with description, how ever we appreciate even more if you create
failing test.ReleaseRelease is done viatwine. The whole package is uploaded in the form of .dist file.To create .dist file use command:python setup.py sdist bdist_wheelNow our binary .dist file is created, now we need to upload it using the below command:python -m twine dist/*Alternatively if you want to selfhost in a custom PyPI repo you can also upload there as well:python -m twine upload--repository-url https://gitlab.com/custom/repo/path dist/* --cert /custom/certTestingTests are written in pytest and stored in tests directory. Library has 100% test coverage.If you found an error, write a failing test first.Run the tests by following command:pytest identifier_tools
