Expansion to 2-series Bank Identification Numbers (BINs)

Bank Identification Numbers (BINs), which are the first six-digits of the account number, are fundamental to payments. They identify the issuing institution for the account and ensure that each transaction is routed correctly. 

Mastercard® has received an additional range of 2-series numbers to add to the 5-series that we currently provide. The 2-series BINs operate in the same way as the 5-series and we have made changes to our systems to accommodate the new numbers. Readiness for the 2-series across our issuers, merchants and other partners is tracking on target dates listed below. Mastercard customer financial institutions can expect to be issued 2-series BINs starting in 2017.

What issuers need to know

Issuers will need to upgrade their systems to be compatible with 2-series BINs. Analysis of all systems should be done to determine any changes required. Software providers may have updates available and internally developed solutions may require enhancements. The addition of 2-series BIN/IINs (Bank Identification Numbers and Issuer Identification Numbers) is intended to fuel future payment industry growth by ensuring the best safety and security measures are in place.

Potential implications for issuers

  • Routing & processing
  • Reporting & reconciliation
  • Dispute processing
  • Rewards & loyalty
  • Online banking
  • Balance transfers
  • P2P payment processing
  • Card production
  • Card design

Beyond the BIN: Account range

The account range includes the BIN plus additional digits to identify the issuer and customer segments. In addition to the expanded BIN range, Mastercard is also working with issuers and partners to look more closely at the account range as an opportunity to provide a flexible, long-term solution to BIN supply challenges. Account ranges also provide issuers and industry partners with the following:

  • More robust product/portfolio segmentation
  • A way to assign features and benefits
  • Opportunities to power new functionality and fuel innovation

What the numbers mean

  • BIN - the first 6 digits - identifies the issuing institution for each customer account and enables transactions to be routed properly.
  • Account range - the next 1-5 digits - is how accounts are managed and segmented. Issuers use the account range to support ongoing innovation and safety and security.
  • The customer identification number makes up the remaining digits. It is unknown to Mastercard and is defined and managed by the issuer.
