About is a public web service for searching Issuer Identification Numbers (IIN).

The first 6 or 8 digits of a payment card number (credit cards, debit cards, etc.) are known as the Issuer Identification Numbers (IIN), previously known as Bank Identification Number (BIN). These identify the institution that issued the card to the card holder.

This web service is comprised of multiple data sources providing the information of credit and debit cards. Although the service is very accurate, don't expect it to be perfect.
