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 cards 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 compromising or changing your PCI compliance requirements.

Finding BINs in the gateway

For a single transaction, you can view the associated card's BIN in the Control Panel. Find these details by running a transaction search:

  1. Log into the Control Panel
  2. Click on Transactions in the navigation bar
  3. Scroll to the Transaction Search section
  4. Define your desired parameters and click the Search button

You will see the BIN in the search results, as the first 6 digits under the Payment Information column.

If you want to compare BINs across multiple transactions, download your transaction search into a CSV file by clicking the Download button at the top of the search results page. The BINs will be in the First Six of Credit Card column of the CSV file.

You can also find BINs by searching 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 BIN databases may vary, depending on card brand and type.
