How Denmark VAT numbers are built

DK followed by 8 digits: the company's CVR number, or an SE number for a part of a business.

Check digit

The weighted sum of the digits (weights 2, 7, 6, 5, 4, 3, 2, 1) is divisible by 11. The validator checks it.

Common mistakes

Danish numbers are often written in pairs (13 58 56 28); the spaces 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 Danish Tax Agency (Skattestyrelsen), and VIES asks that register for you. Where Denmark shares them, VIES also returns the registered name and address.
