MasterCard has introduced a new 2-series to their Bank Identification Numbers (BINs). The BIN is the first 6 digits of a credit card number  and identifies the card’s issuing institution. Up until now, MasterCard BINs have only been in the 5-series range.

MasterCard began issuing the 2-series BINs in 2017. The range is from 222100 to 272099. The new BIN range is subject to the same rules as the existing MasterCard 5-series BIN range. The deadline for compliance is June 15, 2017 to avoid potential fines.
