IBAN format · NO

Parts of a Norway IBAN and their positions
Positions	Part	In the example
1–2	Country code	NO
3–4	Check digits	93
5–8	Bank code	8601
9–14	Account	111794
15	National check digit	7

The BBAN, segment by segment

The registry writes the BBAN in SWIFT notation: n is a digit, a an upper-case letter, c a letter or digit, and the ! means a fixed length. 4!n6!n1!n reads:

Norway IBAN example

NO93 8601 1117 947 is the sample the SWIFT IBAN Registry publishes for Norway: a well-formed IBAN for showing the format, not a real account. Written electronically it has no spaces (NO9386011117947); on paper it is printed in groups of four.

Its check digits, worked through with ISO 7064 mod 97-10:

Move the country code and check digits to the end
86011117947NO93
Replace each letter with two digits (A = 10 … Z = 35)
N = 23, O = 24
86011117947232493
Divide that number by 97 and keep the remainder
Remainder 1. A valid IBAN always leaves 1, so the check digits are right.
Where the check digits come from
Put 00 in their place (NO00…), repeat steps 1–3: remainder 5. The check digits are 98 − 5 = 93.

SEPA

Norway is in the Single Euro Payments Area, so SEPA credit transfers and direct debits can reach NO IBANs; whether a given bank takes part is up to that bank.

What the format can and can’t tell you

Valid means the structure and check digits are right — not that the account exists or can receive payments.
National check digits inside the BBAN (e.g. the French RIB key, or the Spanish, Belgian and Italian CIN digits) are not verified.
Bank and branch codes are read from their positions; they are not looked up in a bank directory.
