Convert Hungary IBANs to their BIC
Every Hungary IBAN is 28 characters long and starts with HU. 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 Hungary IBAN format
Example of a valid Hungary IBAN:
HU42 1177 3016 1111 1018 0000 0000
| Segment | Length | Example | Meaning |
|---|---|---|---|
| Country code | 2 | HU | Always HU |
| Check digits | 2 | 42 | ISO 7064 mod-97 checksum over the whole IBAN |
| Bank code | 3 | 117 | Numeric code identifying the Hungarian bank |
| Branch code | 4 | 7301 | Numeric code identifying the branch |
| Check digit | 1 | 6 | National check digit for the bank/branch part |
| Account number | 15 | 111110180000000 | Numeric account identifier |
| Check digit | 1 | 0 | National check digit for the account part |
Hungary keeps the forint (HUF) and its 28-character IBAN — tied for the longest in SEPA with Poland — contains two separate national check digits besides the ISO mod-97 check.
How to get the BIC from a Hungary IBAN
Validate the IBAN
Check the length (exactly 28 characters for HU) 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.
