How Poland VAT numbers are built
PL followed by 10 digits, the NIP tax identification number.
Check digit
The 10th digit is a weighted modulo-11 check digit (weights 6, 5, 7, 2, 3, 4, 5, 6, 7). The validator checks it.
Common mistakes
- A Polish business is only in VIES after registering as a VAT-UE taxpayer; an active domestic VAT payer may not be.
- NIPs are often written with dashes (856-734-62-15); the dashes are only formatting.
Is the number registered?
A valid format and check digit only mean the number could exist. Whether it is currently registered for VAT is known to the National Revenue Administration (KAS), and VIES asks that register for you. Where Poland shares them, VIES also returns the registered name and address.
Check a Poland number with the validator above, in the VAT number checker or on the Sprawdzenie VAT UE (Polish) page, or up to 50 at once with the bulk VAT validator.
