Pythonic VAT validation library 🌍💳✅

• Offline VAT code validation using country specific regular expressions and checksum algorithms;
• Online validation for European Union VAT codes using VIES web service;
• VAT code sanitization;
• Fully annotated with type hints, for a better IDE and mypy development experience;
• Tested and validated against 1697 different VAT codes.

vat-validator is distributed as standard pip library, and can be installed by running:

pip install vat-validator

To install the latest development version directly from git:

pip install git+git://github.com/ajcerejeira/vat-validator.git

>>> from vat_validator import inspect_vat, sanitize_vat, vat_is_valid
>>> vat_is_valid('PT', 'PT 502 011 378')
True
>>> sanitize_vat('PT', 'PT 502 011 378')
'502011378'

To validate a VAT number with VIES web service:

>>> from vat_validator.vies import check_vat
>>> check_vat('PT', '502 011 378')
CheckVATResult(country_code='PT', vat='502011378', request_date=datetime.date(2019, 6, 8), valid=True, name='UNIVERSIDADE DO MINHO', address='LG DO PACO\nBRAGA\n4700-320 BRAGA')

These are the goals before the 1.0.0 release:

• ❌ Have a comprehensive test suite with valid and invalid VAT codes for each country.
• ❌ Compare the validity of each VAT code used in tests with TIN web service.
• ✅ Remove zeep dependency, by using standard library urllib to make SOAP requests to VIES web service, making this a module without any dependencies.
• ❌ Add support for async requests to VIES web service.
