What IBAN-Test validates for Greece

Validation covers normalization, country assignment, the fixed 27-character length, the country-specific segment structure and MOD-97. Account ownership and real-time account existence are not checked.

Spaces are removed and the representation is normalized.

2. Country and structure

GR, the length and the segment sequence are checked.

3. MOD-97

The international checksum catches many typing errors.

4. Available depth

The bank identifier is compared with the available directory.

What a valid IBAN from Greece does not prove

Formal validity is a strong signal against input errors, but it is not real-time confirmation of an account.

No existence confirmation

The account may be closed or unreachable.

No account-holder match

A person or company name is not compared with the IBAN.

No payment guarantee

A valid IBAN does not guarantee that a payment will be accepted.

Bank data can change

Results depend on the bank directory currently available to IBAN-Test.

Privacy: The input is transmitted only for validation and is not placed in the page URL.
