Bank Identification Number (BIN) Lookup

This simple yet powerful BIN lookup tool allows merchants and payment processors to instantly identify key details about a payment card based on its first few digits.

By providing insights into the issuing bank, card type, and geographic region, a BIN lookup tool serves as an invaluable resource for businesses looking to optimize their payment processing workflows and enhance their overall operations.

What is a Bank Identification Number?

At its core, the BIN lookup tool extracts critical information from a card number by analyzing the first four to eight digits. These digits, known as the BIN or Issuer Identification Number (IIN), are a unique identifier for the financial institution that issued the card.

While payment processors automatically use this information behind the scenes to route transactions to the correct bank, the BIN lookup tool brings this data to the forefront for merchants and other stakeholders.

BINs are placed at the beginning of the card number, after the first digit, which is called the Major Industry Identifier (MII) and tells you which card network the card is associated with. The BIN code that follows identifies the issuing bank, and can also tell you what type of card it is and which country the issuer is located in.

The BIN numbering system was created by the American National Standards Institute and the International Organization for Standardization.

What Can You Do With a Bank Identification Number?

The primary purpose of the BIN is to route transaction authorization requests to the right issuing bank.

Merchants don’t need to look up BINs when they’re processing transactions—the payment processor handles that, and authorizations are usually completed in a matter of seconds.

However, when customers provide payment card information to a merchant through their website or payment terminal, the merchant then has access to BIN data such as the location and card type. This can warn you when you might be processing a transaction for a customer in a country you’re not allowed to ship to due to export laws, or when a customer is setting up recurring payments on a limited-use prepaid card.

A BIN can also be used to make decisions related to fraud prevention.

How Can Bank Identification Numbers Help Stop Fraud?

To stop sophisticated credit card fraud attempts, merchants need to evaluate multiple data points (often with the help of AI-based fraud filters) to estimate the potential risk of a given transaction.

For instance, it can help merchants  verify whether a transaction is originating from a legitimate source or if there’s cause for suspicion. By cross-referencing the card’s issuing bank with other transaction data, merchants can identify potential fraud risks early in the payment process.

A mismatch in geographic data, such as a card issued in one country being used in another without a clear reason, can alert businesses to potential red flags, allowing them to take precautionary measures before completing a transaction.

How Can Bank Identification Numbers Help With Chargeback Management?

Another significant use of the BIN lookup tool lies in the realm of chargeback management. By identifying the issuing bank, merchants can gain insights into patterns related to chargebacks.

For example, if a significant number of chargebacks are associated with cards from a particular bank, merchants may be able to adjust their strategies or seek further communication with the issuing institution to address the issue. This makes the BIN lookup tool a critical component in helping businesses maintain control over payment disputes, ultimately reducing losses.

The best way to implement a strong chargeback defense strategy is to analyze your chargeback data and determine exactly why they’re happening and where they’re coming from.

Conclusion

Big data has taken over the world, and it’s not always easy to sift the useful information from the ephemera. When it comes to payment card numbers, it’s worth remembering that those first few digits always have a story to tell. Knowing which card network and issuing bank you’re dealing with can be very helpful when you’re trying to get the upper hand against fraud and chargebacks. With the BIN lookup tool we’ve provided above, merchants can immediately access the issuer details for any payment card number.
