Convert Sweden IBANs to their BIC
Every Sweden IBAN is 24 characters long and starts with SE. 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 Sweden IBAN format
Example of a valid Sweden IBAN:
SE45 5000 0000 0583 9825 7466
| Segment | Length | Example | Meaning |
|---|---|---|---|
| Country code | 2 | SE | Always SE |
| Check digits | 2 | 45 | ISO 7064 mod-97 checksum over the whole IBAN |
| Bank code | 3 | 500 | Numeric code identifying the Swedish bank |
| Account number | 16 | 0000005839825746 | Numeric account identifier, zero-padded |
| Check digit | 1 | 6 | National check digit |
Sweden keeps the krona (SEK). Swedish IBANs are only used for cross-border payments — domestically, banks still use clearing + account numbers, which the IBAN zero-pads into a fixed 24-character format.
How to get the BIC from a Sweden IBAN
Validate the IBAN
Check the length (exactly 24 characters for SE) 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.
