IBAN Structure France

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

France's IBAN has 27 characters in the format FRkk BBBB BGGG GGCC CCCC CCCC CKK. It begins with FR and two check digits, then a 5-digit bank code (Code Banque), a 5-digit branch code (Code Guichet), an 11-character account number (Numéro de compte) and a two-digit national check key (Clé RIB). France was among the early adopters of the IBAN for domestic payments. The historic RIB notation stays in parallel use: Banque + Guichet + Compte + Clé RIB carry the same information as IBAN positions 5–27. For payments from EU/EEA banks to France, required routing details depend on the bank, currency and route; check them in advance with your bank.

Frequently asked questions

How do I check the length of an IBAN from France?
Remove spaces and count 27 characters. The first two characters are FR; the remaining positions follow FRkk BBBB BGGG GGCC CCCC CCCC CKK. A different length is formally invalid for this country format.
What do the check digits in a France IBAN mean?
The two check digits are calculated from the complete IBAN using ISO 7064 MOD-97. They help detect format and transcription errors. A passing checksum does not confirm that an account exists or identify its account holder.
What should I do when an IBAN is formally invalid?
Check the country code, character count, letters and digits, and the check digits. Compare the entry with your bank records or ask the bank for the correct IBAN. This checker validates structure and checksum; it does not verify account ownership or payment approval.
