Government-issued number identifying a food-stamp-participating merchant location.
The United States Department of Agriculture, Food and Nutrition Service (FNS) must authorize merchants who wish to accept food stamps. A merchant applies directly to this agency. If the necessary requirements are met, the merchant is issued a certificate with a seven-digit number for each participating merchant location. This number, referred to as the FNS number, uniquely identifies the merchant location to the state EBT processor system. In the FDMS system, this number must be set up in the Cross-Reference File (XREF) under usage indicator I. The number is pulled from the XREF file and inserted into each transaction request before the request is passed on from the front end. This number is used only for Food Stamp transactions
If this number is not supplied, FDMS will attempt to obtain it from a Merchant Control File in their system.
