Issuers will need to upgrade their systems to be compatible with 2-series BINs, but all systems should be analyzed to determine if any additional changes are required. How will the 2-series BINs impact issuers? The 2-series BINs adhere to the current (2015 revision) ISO industry standard and will work exactly the same way as the 5-series BINs do today.Ĭards with 2-series BINs were first issued in 2017. This will effectively double the existing supply of Mastercard BINs - allowing merchants to accept millions more transactions and our issuers to continue to support business growth. To expand supply, Mastercard is rolling out an additional 50,000 six-digit BINs (222100-272099).

What is Mastercard doing to alleviate the limited supply of BINs? So, the industry needs more BINs to manage industry growth. The International Organization for Standardization (ISO) which has published ISO/IEC 7812 to define BINs, and the American Bankers Association which is the registration authority managing the numbers, has a limited supply of unused or unallocated numbers. With new devices and technologies emerging in a connected world, the industry's finite supply of BINs is reaching current capacities. The payments industry is more complex than ever. The American Bankers Association is the current registration authority that manages the BIN allocation process on behalf of ISO. The ISO/IEC 7812 standard defines an Issuer Identification Number (IIN), known as a BIN within the payments industry. The International Organization for Standardization (ISO), an independent, non-governmental international organization that develops voluntary global standards. Since the 1960s, Mastercard has been closely identified with the 51-55 BIN range. BINs are currently the first six digits of the account number. They identify the issuing institution for each cardholder account and enable transactions to be properly routed. Bank Identification Numbers (BINs) are fundamental to payments.
