What is BIN/IIN?

What is BIN?

Bank Identification Number (“BIN”) or Issuer Identification Number (“IIN”) is the first six digits (no spaces) of a bank-issued card. It is commonly used in credit cards, debit cards, stored-value cards and some gift cards. BIN is used to validate card issuer information through the BIN database which helps to prevent online fraud.

BIN holds information of: brand of the card ( Visa, Master Card, …), name of the issuing institution/ bank, country of issuance, type of the card (Debit / Credit), category of the card

What is Bin Checker API?

Our BIN Checker API uses the first 6 digits of an issuer card to retrieve the information. It contains one of the most accurate lists of BINs and their relevant data from the issuer banks all over the world.

  • If BIN number doesn’t exist in our BIN Lookup, an HTTP 404 response is returned.
  • If some of the relevant information is not currently available in our database, you will see them as empty fields in the response. You can inform us about such cases, and we'll do our best to overcome the situation.

We have spent a large amount of time compiling BIN numbers from as many sources as possible. This process includes filtering and refining the level of information and checking their accuracy. We update our BIN database regularly to provide you the most accurate information. But please keep in mind that it is not possible to maintain a 100% perfect list of BIN/IIN numbers as they grow rapidly. If you have any comments or requests, please notify us.

See it in Action!

Is Bin Checker API Secure?

BIN Checker API uses only the first 6-digits of a card, and it doesn’t store/display any personal information. APILayer is a legal entity in European Union and regulated by its laws. We never store any sensitive information on our servers and fully respect your privacy.

What is BIN Checker used for?

BIN Checker is mainly used in commercial businesses for fraud prevention by providing an extra security layer to protect both customers and merchants.

  • Online stores use BIN Checker to validate transactions against fraud and identity theft. With a simple example, if your device location where you make the transaction does not match with the country of issuance information that returns from BIN lookup, the transaction might be blocked due to fraud and additional validation can be asked.
  • Online merchant’s system can recognize the type of the card easily and ensure if they accept that card brand (Visa, Mastercard …) before attempting to further authorization.
