How can I check my Costco Cash Card balance?

Members may check their balance at Here's how:

  1. Visit the homepage, and find Costco Cash Card Balance (located near the bottom).
  2. 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.
  3. 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).
  4. Select the "Check Balance" button. The balance should immediately be displayed.
