stdnum.it.iva¶
Partita IVA (Italian VAT number).
The Partita IVA (Imposta sul valore aggiunto) consists of 11 digits. The first 7 digits are a company identifier, the next 3 refer to the province of residence and the last is a check digit.
The fiscal code for individuals is not accepted as valid code for intracommunity VAT related operations so it is ignored here.
