How a Norway IBAN is structured
A Norway IBAN is read left to right: a 2-letter ISO 3166 country code (NO), 2 MOD 97 check digits, then a 11-character BBAN. The BBAN is split into 3 fields: 4 digits, 6 digits, 1 digit.

How Norway IBAN check digits work
The two digits at positions 3–4 are a MOD 97-10 checksum computed from the country code and the BBAN. To verify it, the IBAN is rearranged (BBAN first, country code and check digits last), letters are converted to numbers (A = 10, B = 11, …), and the whole integer is taken mod 97. A valid IBAN has a remainder of 1. This catches any single-digit typo and most transposition errors — which is why a one-character mistake is enough to make a Norway IBAN fail validation instantly.

- What country code does a Norway IBAN start with?

- How do I validate a Norway IBAN?
- Paste the IBAN into the validator on this page — it checks the character set, the 15-character length, and the MOD 97 check digits, all in your browser. You can also open the full IBAN validator with a Norway example pre-filled.
- Does a valid Norway IBAN mean the account exists?
- No. Validation only confirms the IBAN is structurally well-formed and the check digits are correct per ISO 13616. It does not verify the account exists, is open, or belongs to anyone. Always confirm with the recipient or their bank before sending money.
⚠️ Validation only checks structure and check digits against ISO 13616. A valid Norway IBAN does not guarantee the account exists or is open. Always confirm with the recipient or their bank before initiating a transfer.
