Mastercard is driving practical and effective solutions to address the industry’s Bank Identification Number (BIN) situation – expanding BIN supply and inspiring smarter BIN use through more efficient systems. To expand supply, MasterCard is rolling out an additional range of six-digit BINs (222100-272099). This will effectively double the existing supply of MasterCard BINs – allowing the payment ecosystem to process millions more transactions. The 2-series BINs adhere to today’s ISO industry standard and will work exactly the same way as the 5-series BINs do today.
