Convert Greece IBANs to their BIC
Every Greece IBAN is 27 characters long and starts with GR. The bank identifier embedded inside it is what resolves to a BIC/SWIFT code, the bank's name and address, and its SEPA reachability.
The Greece IBAN format
Example of a valid Greece IBAN:
GR16 0110 1250 0000 0001 2300 695
| Segment | Length | Example | Meaning |
|---|---|---|---|
| Country code | 2 | GR | Always GR |
| Check digits | 2 | 16 | ISO 7064 mod-97 checksum over the whole IBAN |
| Bank code | 3 | 011 | Numeric code identifying the Greek bank |
| Branch code | 4 | 0125 | Numeric code identifying the branch |
| Account number | 16 | 0000000012300695 | Alphanumeric account identifier |
Greek IBANs are 27 characters, with a 3-digit HEBIC bank code assigned by the Bank of Greece that maps one-to-one to the institution’s BIC.
How to get the BIC from a Greece IBAN
Validate the IBAN
Check the length (exactly 27 characters for GR) and the ISO 7064 mod-97 checksum. Both are local computations — no lookup needed yet.
Extract the bank identifier
The bank code (3 characters) inside the BBAN identifies the institution holding the account.
Resolve it to a BIC
Map the bank identifier to the institution's BIC via registry data — or send the IBAN to the API and get BIC, bank details and SEPA flags in one response.
Resolve it with one API call
Send the IBAN to POST /v1/convert and get back the BIC, bank details and the four SEPA reachability flags. Invalid and not-found lookups are always free.
