Convert Iceland IBANs to their BIC

Every Iceland IBAN is 26 characters long and starts with IS. The bank identifier embedded inside it is what resolves to a BIC/SWIFT code, the bank's name and address, and its SEPA reachability.

Iceland is unique in SEPA: its IBAN embeds the account holder’s kennitala (national ID number), so the IBAN identifies not just the account but its owner.

How to get the BIC from a Iceland IBAN

01

Validate the IBAN

Check the length (exactly 26 characters for IS) and the ISO 7064 mod-97 checksum. Both are local computations — no lookup needed yet.

02

Extract the bank identifier

The bank and branch code (4 characters) inside the BBAN identifies the institution holding the account.

03

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.

curl https://api.iban2bic.com/v1/convert \
  -H "Authorization: Bearer ibk_live_xxx" \
  -H "Content-Type: application/json" \
  -d '{ "iban": "IS140159260076545510730339" }'
