Discover IIN Data Lookup Service is one of 17 APIs that [Discover](https://apis.io/providers/discover/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include BIN, IIN, Reference Data, Payments, and Card Network. The published artifact set on APIs.io includes API documentation and an API reference.

The IIN Data Lookup Service returns up-to-date Issuer Identification Number (BIN) range data so an acquirer, processor or merchant can identify the issuer, the card product and the network behind a card number before routing or authorising a transaction. The published surface includes a full IIN list, a simplified summary list, a per-network summary and a single-IIN lookup that returns every field attribute for one range, alongside a health check. It is the one Discover API product documented with real GET reads rather than the POST-dominant pattern the rest of the portfolio uses.
