Include the country prefix. EU numbers are checked against VIES in real time, UK numbers with a separate live check.

How Sweden VAT numbers are built

SE followed by 12 digits: the 10-digit organisation number (the personal identity number for sole traders) and 01.

Check digit

The 10th digit is a Luhn check digit over the organisation number. The validator checks it.

Common mistakes

Without the final 01 it is an organisation number, not a VAT number.
Drop the hyphen of the organisation number: XXXXXX-XXXX becomes SEXXXXXXXXXX01.

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 Swedish Tax Agency (Skatteverket), and VIES asks that register for you. Where Sweden shares them, VIES also returns the registered name and address.

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

The response says whether the format and checksum are valid and whether the number is registered, with name and address where Sweden provides them.
