Questions
How many characters is an IBAN in Luxembourg?
An IBAN from Luxembourg always has 20 characters: the country code LU, 2 check digits and a 16-character national account number (BBAN).
How do I know a Luxembourg IBAN is correct?
Check the length (20), that it starts with LU, and the mod-97 check digits. Our free IBAN checker does all three in one step and shows the bank when it is known.
Is Luxembourg in SEPA?

Does a valid IBAN mean the account exists?
No. The check proves the number is well formed and the check digits match. Only the bank can confirm that the account is open and whose it is.
