How Hungary VAT numbers are built

HU followed by 8 digits: the first block of the 11-digit Hungarian tax number (adószám), which is written 12345678-1-12.

Check digit

The 8th digit is a weighted modulo-10 check digit (weights 9, 7, 3, 1). The validator checks it.

Common mistakes

Use only the first 8 digits of the domestic tax number: 12345678-1-12 becomes HU12345678.

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 Tax and Customs Administration (NAV), and VIES asks that register for you. Where Hungary shares them, VIES also returns the registered name and address.

Check a Hungary number with the validator above, in the VAT number checker, or up to 50 at once with the bulk VAT validator.
