A method for inferring a merchant geolocation includes: storing a plurality of transaction data entries, each including an account identifier, merchant identifier, and transaction time; storing a plurality of merchant profiles, each including a merchant identifier and geolocation; identifying a first set of transaction data entries, each entry including a common merchant identifier; identifying a second set of transaction data entries, each entry including a different merchant identifier corresponding to a merchant within a predetermined distance of a merchant corresponding to the common merchant identifier; transmitting an identification value associated with each transaction data entry in the first and second sets; receiving geolocation data entries for each identification value, each entry including a location time and geolocation; and identifying an updated merchant geolocation for the merchant corresponding to the common merchant identifier based on the geolocation included in geolocation entries that match transaction data entries in the first set. |

1. A method for inferring a merchant geolocation, comprising:
storing, in a transaction database, a plurality of transaction data entries, wherein each transaction data entry includes data related with a payment transaction including at least an account identifier associated with a payment account involved in the related payment transaction, a merchant identifier associated with a merchant involved in the related payment transaction, and a transaction time and/or date; storing, in a merchant database, a plurality of merchant profiles, wherein each merchant profile includes data related to a merchant including at least a merchant identifier and a merchant geolocation associated with the related merchant; identifying, in the transaction database, a first set of transaction data entries, wherein each transaction data entry in the first set includes a common merchant identifier; identifying, in the transaction database, a second set of transaction data entries, wherein each transaction data entry in the second set includes a different merchant identifier where the merchant geolocation included in a corresponding merchant profile is within a predetermined distance of the merchant geolocation included in a specific merchant profile that includes the common merchant identifier; transmitting, by a transmitting device, at least an identification value associated with the account identifier included in each transaction data entry in the first set of transaction data entries and each transaction data entry in the second set of transaction data entries to a probe operator; receiving, by a receiving device, one or more geolocation data entries for each of the transmitted identification values from the probe operator, wherein each geolocation data entry includes the corresponding identification value, a location time and/or date, and a geolocation; and identifying, by a processing device, an updated merchant geolocation for the merchant related to the specific merchant profile based on the geolocation included in received geolocation data entries that correspond to transaction data entries in the first set of transaction data entries based on correspondence between the account identifier associated with the identification value and the location time and/or date in the respective geolocation data entry and the account identifier and transaction time and/or date in the respective transaction data entry. |
