Calculate or check a Greek IBAN

Enter the bank code, branch code and account number. The calculator pads short numbers with zeros, works out any national check digits you leave empty and adds the two IBAN check digits.

Switch to Check to paste an IBAN instead: it tests the length, characters, check digits and national check, and shows the bank, branch and account parts. Nothing you type leaves the page.

Frequently asked questions

  • 27 characters: GR, two check digits, then the bank code, branch code and account number. Printed in groups of four, it looks like GR16 0110 1250 0000 0001 2300 695.

  • Not reliably. The four-digit branch code is not always the start of the account number, and the Hellenic Bank Association advises taking the IBAN from the bank, which prints it on statements and in e-banking. The calculator builds it when you know the bank, branch and account parts.

  • Yes. Greece is an EU member state, so it is in SEPA: euro payments to a Greek IBAN can go by SEPA credit transfer.

  • With the ISO 7064 mod 97-10 algorithm. The bank code, branch code and account number and the country code GR are turned into digits, and the two check digits are chosen so the whole number leaves a remainder of 1 when divided by 97. The calculator does this for you and rejects any input that cannot make a valid GR IBAN.

  • Yes. The calculator and the checker run entirely in your browser: the details you enter are never sent to a server, stored or shared. There is no sign-up and no fee.

  • Yes. The calculator covers 41 countries and the checker all 89 in the SWIFT IBAN registry. Pick a different country in the form above, or open its page from the list below.
