Members may check their balance at Costco.com. Here's how:
- Visit the homepage, and find Costco Cash Card Balance (located near the bottom).
- Enter your Costco Cash Card number, which you'll find on the back of your Costco Cash Card. It's a unique number and is used to identify your Costco Cash Card.
- Type in the four-digit PIN, which is also located on the back of your Costco Cash Card. If you don't see the four-digit PIN right away, you may need to scratch off the silver security feature on the back (some cards have it, but don't worry if yours doesn't).
- Select the "Check Balance" button. The balance should immediately be displayed.
