public string MerchantFNSNumber { get; set; }
Public Property MerchantFNSNumber As String

Default Value



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. For eWIC processing, this field contains the state assigned retailer ID of the merchant. 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 for Food Stamp and eWIC transactions.

If this number is not supplied, FDMS will attempt to obtain it from a Merchant Control File in their system.
