IBAN for National Bank Of Greece S.A.

The Greece IBAN consists of exactly 27 characters and includes three elements:

• Country code (positions 1–2): Greece identifies Greece according to the ISO 3166-1 standard.
• Check digits (positions 3–4): used to automatically verify that the IBAN is valid.
• BBAN (positions 5–27): corresponds to the national account number, whose structure depends on Greece.

It depends on the destination of the transfer:

• Within the SEPA zone: no. For all euro transfers within the SEPA zone, the IBAN is sufficient. The BIC has been determined automatically since SEPA was introduced in 2014.
• Outside the SEPA zone: yes. For international transfers (for example to the United States or Asia), the BIC (also known as the SWIFT code) is required.

You can find the BIC for National Bank Of Greece S.A. on your bank statement or under "Account details" online.

Yes, but with an important difference depending on the destination country:

• Within the SEPA zone (including all EU member states as well as Switzerland, Norway, and Iceland): the IBAN is sufficient for all euro transfers. A BIC is not required, it's determined automatically.
• Outside the SEPA zone (e.g. USA, Canada, Asia): the IBAN is accepted, but must be accompanied by the BIC for National Bank Of Greece S.A.. In addition, many receiving banks outside Europe require the bank's full address.
• Receiving international payments: you can also use your National Bank Of Greece S.A. IBAN to receive transfers from abroad. It's recommended to provide both the IBAN and BIC; for payments from non-SEPA countries, the BIC is essential.

Note: for transfers in foreign currencies (e.g. USD, GBP), currency conversion fees may apply. Check with National Bank Of Greece S.A. in advance for the applicable terms.

No, and this distinction is crucial for transfers:

• What a valid IBAN confirms: the length, country code, and check digits are correct according to the Modulo-97 method (ISO 13616). The IBAN is formally valid.
• What a valid IBAN does not confirm:
  ❌ The account actually exists at National Bank Of Greece S.A.
  ❌ The account is active and able to receive funds
  ❌ The account holder is correct
• Why this matters: an IBAN can pass all mathematical validation checks and still not correspond to a real account: for example, if digits were transposed, accidentally creating another formally valid combination.

Recommendation: ask the recipient to confirm the IBAN in writing, especially for a new business relationship or a large amount. Account existence can only be verified by National Bank Of Greece S.A. itself or through a test transfer.

It depends on the error in the IBAN, there are two scenarios:

In this case:

• the receiving bank must cooperate to return the funds
• your bank can initiate a recall procedure upon request
• reimbursement is not guaranteed, especially if the funds have already been withdrawn
• for transfers outside SEPA, recovery is more complex and may incur fees

Recommendation: always verify every IBAN before making a transfer (using a verification tool) and confirm it directly with the recipient if in doubt. This is especially important for large amounts or new business relationships.
