With alphanumeric characters
The IBAN has a fixed number of characters for every country, up to 34 alphanumeric characters.
In Greece it has 27 alphanumeric characters from which:
- The first 2 are alphabetic characters that specify the country where the account is held (GR for Greece).
- The next 2 are the check digits that validate the entire IBAN.
- The final part is the Basic Bank Account Number or BBAN, which in most cases contains the number that identifies the bank (3 digits), the branch (4 digits) and the customer's account number (16 digits).
When the digits of the account number are less than 16, we complete it with zeros, placed at the beginning of the account.
Example:
Basic Bank Account Number (BBAN): 01401010101002101047414
IBAN: GR 16 014010101002101047414
Tip: You may get it online and in printed form. When printed, a space is inserted after every group of four characters. For example, in printed form it is GR16 0140 1010 1010 0210 1047 414, while in online form it is GR16014010101002101047414.
