Effective October 14th, 2016, MasterCard is issuing a new range of credit card and debit cards with account numbers that begin with “2”. This new range of account numbers is processed in exactly the same way as existing MasterCard accounts that begin with “5”. However,without an update, the ChargeLogic Payments software will be unable to recognize MasterCard account numbers that begin with “2”. Supporting this new range is a requirement for all merchants that accept MasterCard, and failure to accept a new card after the October deadline may result in fines. This means that every ChargeLogic Payments customer must have a critical update applied to their databases to avoid any rejected transactions. Please contact us if you would like to avoid the issues described above.
