With EU VAT handling rules becoming ever more ridiculous and complicated, businesses within the EU are faced with the complexity of having to validate VAT numbers.pyvat was built forIconfinder's marketplace to handle just this problem.

Validation of VAT numbers is performed in two steps: firstly, the VAT number is checked against an expression for the given country if one such is available, after which it is checked against a registry if one such is available.

Calculation of VAT rates for sales is supported within the EU for items covered by the new EU directive forVAT on telecommunications, broadcasting and electronic services.

To install requests, do yourself a favor and don't use anything other thanpip:

$ pip install pyvat

pyvat exposes its functionality through three simple methods:

If possible, the VAT number will be checked against available registries.

DefaultNone prompting detection.
Returns:	True if the VAT number can be fully asserted as valid orFalse if not, otherwiseNone indicating that the VAT number may or may not be valid.
