Questions
How many characters does a Norway IBAN have?
15 characters: the country code NO, two check digits, and a 11-character national account number (BBAN).
Is Norway in SEPA?
Yes, Norway is in the Single Euro Payments Area, so euro transfers use SEPA credit transfers.
Does a valid checksum mean the account exists?
No. The mod-97 checksum catches typos; it does not confirm the account or its holder. In the Netherlands, your bank's name check (Verificatie van Betalingsontvanger) matches the holder.
