What is a Bank Identification Number?

A Bank Identification Number (BIN) is a sequence of digits found on a payment card, forming part of the Primary Account Number (PAN). These digits serve to identify key aspects of the card, including the issuing bank or institution, the card type, and the card network (Visa, MasterCard, etc.).

Traditionally, BINs were the first six digits of the payment card. However, in 2022, the standard BIN length was increased to eight digits to accommodate the growing number of cards in circulation. In some cases, a BIN may be even longer.

The BIN plays a key role in ensuring the correct routing, processing, and validation of transactions.

Where Did BINs Originate?

BINs were developed in the 1960s by the American Bankers Association (ABA) and the International Organization for Standardization (ISO) as a global standard for secure, efficient payment processing.

The Anatomy of a BIN: What Do the Numbers Mean?

The string of numbers within a BIN holds a wealth of information that’s critical for merchants and payment processors. These digits reveal:

  • The institution that issued the card
  • The type of card (debit, credit, prepaid)
  • The card network (Visa, MasterCard, etc.)
  • The country of origin
  • The card’s level (e.g., standard, gold, business)

Major Industry Identifier (MII)

The first digit of a BIN is known as the Major Industry Identifier (MII). This number reveals the card’s industry category. For instance:

  • 3: Travel and entertainment cards (e.g., American Express)
  • 4: Banking and financial cards (e.g., Visa)
  • 5: Banking and financial cards (e.g., MasterCard, Discover)

How BINs Are Used in Payment Processing

BINs serve a vital role in every stage of a transaction:

  1. Issuer Identification: Identifies the issuing bank or financial institution.
  2. Routing: Directs the transaction to the correct card network for authorization.
  3. Authorization: BINs are checked during authorization to verify the card’s validity and assess fraud risk.
  4. Fraud Prevention: By analyzing BIN data, merchants can spot patterns of fraud and take preventative measures.
  5. Verification: BINs help determine whether additional security checks (e.g., CVV or 3D Secure) are needed.

How Merchants Can Use BINs to Optimize Payment Processing

Merchants can use BIN data to improve transaction handling and reduce costs. Here's how:

1. Reduce Payment Fees

By understanding which BINs belong to certain card networks, merchants can route transactions through local networks, saving on processing fees.

2. Enhance Fraud Prevention

BIN analysis can flag high-risk transactions, allowing merchants to prevent fraud before it occurs. This reduces chargebacks and protects revenue.

3. Tailor Payment Strategies Per Market

Merchants can use BIN data to offer region-specific services, such as currency conversions or payment options that align with local preferences.

4. Gain Insights into Customer Behavior

By analyzing BIN data, merchants can uncover customer demographics, spending habits, and payment preferences, which can help refine marketing strategies and product offerings.

How Can Merchants Access BIN Data?

Merchants cannot access BIN data directly from card networks. Instead, they typically obtain it through third parties, such as Payment Service Providers (PSPs). When evaluating a BIN data provider, ensure they source their data directly from the schemes for accuracy.

Even with access, many merchants struggle to leverage BIN data meaningfully due to challenges like inconsistent data, complex file structures, and the need to manage multiple PSPs.

The Future of BINs: Longer BINs and Merchant Impact

In 2022, the global standard for BINs increased to eight digits, and this trend will likely continue as the number of financial institutions grows. For merchants, this means:

  • The need for more sophisticated systems to handle and analyze longer BINs.
  • Adjusting fraud prevention strategies to accommodate new, longer BINs.
