The first 6 digits of a debit or credit card are known as the bank identification number (BIN), or issuer identification number (IIN).

Looking up the BINs associated with payment methods you’re processing can provide a lot of insight into your business - like identifying trends in declines or purchases (e.g. where most of your customers are located, or what types of cards they use).

You can view and store BINs without affecting your PCI compliance.

Finding BINs in the gateway

You can find the BIN for a card by viewing a transaction’s details in the gateway.

Perform a transaction search for the transactions you’d like to view, then:

  • If you’re searching for a single transaction, you’ll be able to see the BIN in the search results, as the first 6 digits under the Payment Information column.
  • If you’re looking to compare many transactions, download the search results into a .csv file by clicking Download. Open the file, and pivot or search by the First Six of Credit Card column.

You can also query a transaction ID via the API. The response object will include the BIN as one of the parameters, and you can investigate from there.

BIN databases

Once you have a BIN, you can look up information about the card by entering it into a BIN database - we like using

BIN databases typically show the following information*:

  • Type, brand, and level of card (e.g. Gold, Platinum, etc.)
  • Purchase limits
  • If the card is ATM only, electronic only, Maestro, or prepaid
  • Name and country of the bank that issued the card

*Information provided by databases may vary, depending on card brand and type.
