What this check covers

Italian IBANs include a national check character before the domestic bank and branch identifiers.

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.

Italy IBAN structure

The expected layout is IT + 2 check digits + national check character + bank code + branch code + account number. 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.
