I received a Cheesecake Factory gift card a few years ago and never used it. How do I determine whether or not it is still valid without having to go to the restaurant directly?

Those gift cards don't expire so it should be fine

Look at number on the back, call.

Check the card if there is a phone number or a web page where you can call to check the balance of your card

Call them.

Those gift cards don't expire, but if you'd like to check the balance on the card there's a phone number on the back towards the bottom that you can call
