Italy VAT codes not valid about jsvat

[michelem09]

Those aren't Italian VAT numbers but Italian personal tax code (called in Italian "Codice fiscale").
This lib checks only against VAT numbers (for companies) not personal tax code.

Ok strange, thought they were the same. Here in Portugal at least, Vat number and código fiscal are the same number and the same thing. It's the code you give in invoices to let tax authority to link the invoice to someone, and benefit from fiscal IRS

This Vat numbers are valid, but your validator and many others, report as invalid. Ex: MRTMTT25D09F205Z or PCTCHR77S66I470H
