A payment-enabled mobile device is placed in communication with a POS (point of sale) terminal to facilitate a purchase transaction. A user selects a payment account in the payment-enabled mobile device. Payment credentials are transmitted from the payment-enabled mobile device to the POS terminal. The payment credentials include a PAN-length identifier that identifies an issuer of the selected payment account.

Extended-length payment account issuer identification numbers

Systems and methods for use in identifying payment accounts to segments are provided. One exemplary method includes receiving a first indicator for a first location from a communication device, where the communication device is associated with a consumer and the consumer is associated with a payment account issued to the consumer by an issuer. The method also includes appending, by a computing device, the payment account to a first segment based on the first location indicator, and causing at least one rule associated with the payment account to be modified where the at least one rule relates to authorization of transactions in a first region including the first location.

Systems and methods for identifying payment accounts to segments

Transaction data is obtained relating to a current purchase transaction. An account indicator is retrieved. The transaction data is used to transform the account indicator. The transformed account indicator is encrypted to generate an encrypted account indicator.
