IBAN structure with this code

A Swiss IBAN is CH, two check digits, the five-digit IID, then a twelve-digit account part. When the institution holds a QR-IID, the QR-IBAN of a QR-bill carries that number in the same position.

CH51 0027 2000 0000 0000 1

Synthetic example: the account part is a placeholder, this IBAN belongs to nobody. It shows where the code sits inside the IBAN.

QR-IID 30005, 30308: a QR-IBAN with this number expects a QRR reference on the QR-bill.

Get this answer from your own software

The IBANforge API checks an IBAN and names the bank behind it, with its BIC when one is known, reading national registers such as the one on this page. Two ways to start without paying:

Keyless trial

Send an IBAN to POST /v1/iban/validate with no key at all, up to 25 times a week, on that route only. With this page’s example IBAN:

curl -X POST https://api.ibanforge.com/v1/iban/validate \
  -H "Content-Type: application/json" \
  -d '{"iban":"CH5100272000000000001"}'

Free key

200 requests a month on every endpoint once you add an e-mail address and confirm the code sent to it. With no address and no card, it starts at 25 requests a month, straight away.
