To check the balance of your SNAP card or your EBT card, the website you would need to go to would be www.ebtedge.com. There you would enter your 16 digit card number and the pin number for your card. Or if you are not around a place where you can get internet, there is a number on the back of your card that you can call. Here, you will also have to enter your 16 digit card number and pin.
