France IBAN Format: A Complete Guide

French IBANs are 27 characters and include a 5-digit bank code, 5-digit branch code, and 11-character account identifier. Here is the full breakdown.

French IBAN Structure

A French IBAN is always 27 characters long:

  • FR — country code
  • XX — 2 check digits
  • XXXXX — 5-digit bank code
  • XXXXX — 5-digit branch code (code guichet)
  • XXXXXXXXXXX — 11-character account number
  • XX — 2 national check digits (RIB key)

Example: FR76 3000 6000 0112 3456 7890 189

The RIB Key

France uses an additional 2-digit national check called the clé RIB at the end of the BBAN. This is separate from the IBAN check digits and is a legacy of the French domestic banking system. Both the IBAN check digits and the RIB key are validated by most French banking systems.

French Banks and Their Codes

BNP Paribas uses bank code 30004; Société Générale uses 30003; Crédit Agricole varies by region but starts with 18 or 19. These 5-digit codes appear in positions 5–9 of any French IBAN.
