Systems and methods are provided for use in locating one or more merchant terminals based on transaction data associated with the terminals. One exemplary method generally includes accessing, by a computing device, transaction data for a transaction to a payment account between a merchant and a consumer at a merchant terminal where the transaction data includes a terminal ID for the merchant terminal, a merchant ID of the merchant, an acquirer ID for an acquirer associated with the merchant, and a temporal indicator. In addition, the method includes receiving, by the computing device, location data associated with the transaction, identifying, by the computing device, a location associated with the location data as a location of the merchant terminal, and assigning, by the computing device, a score to the identified location indicative of a confidence that the identified location is the actual location of the merchant terminal.
