How Luxembourg VAT numbers are built
LU followed by 8 digits.
Check digit
The last two digits are the first six digits modulo 89. The validator checks them.
Common mistakes
- The Luxembourg national identification number (matricule) is not a VAT number.
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 Registration Duties, Estates and VAT Authority (AED), and VIES asks that register for you. Where Luxembourg shares them, VIES also returns the registered name and address.
Check a Luxembourg number with the validator above, in the VAT number checker, or up to 50 at once with the bulk VAT validator.
