What this check covers
French IBANs are 27 characters and may contain letters inside the account-number portion.
The checker removes spaces, converts the value to uppercase, moves the first four characters to the end, converts letters to numbers, and confirms that the modulo-97 remainder is one.
France IBAN structure
The expected layout is FR + 2 check digits + bank code + branch code + account number + national check digits. This page compares the 27-character fixture with that structure.
A passing checksum does not prove that an account exists, identify its owner, or confirm that a transfer can be completed. An official institution check is still required.
