The easiest way to check your chick-fil-a gift card balance via checking the receipt – look at the bottom of the receipt! The balance will be clearly printed there. You don't need to do anything specific like circling a barcode or performing any calculations.
Just locate your most recent Chick-fil-A purchase receipt and scan the bottom area for a line that says "Gift Card Balance" or similar wording. The remaining dollar amount displayed alongside it is your current balance.
