With SNAP paper vouchers, you will need to call the retailer authorization number for your state (on some SNAP cards the number is on the back of the card) to verify that the customer in front of you has the funds for their purchase, and that those funds are held until the paper voucher can be submitted electronically within 10 days of the transaction.
In some states, when you call for this authorization, the pre-recorded message will ask for your Retailer Number, as well as your FNS number. The Retailer Number is a number that is assigned to each state.
