How Slovakia VAT numbers are built

SK followed by 10 digits, the IČ DPH.

Check digit

The whole 10-digit number is divisible by 11. The validator checks it.

Common mistakes

The DIČ tax ID has the same 10 digits; only VAT payers have an IČ DPH, and only it is valid in VIES.

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 Financial Administration (Finančná správa), and VIES asks that register for you. Where Slovakia shares them, VIES also returns the registered name and address.

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