Cancel Costco Membership In-Store
Visit any Costco warehouse
Go to the Membership Counter at any Costco location. You do not need to go to the same warehouse where you originally signed up. Any location can process your cancellation. The membership counter is usually located near the entrance of the store.
Bring your membership card and photo ID
The primary member must be present with their Costco membership card and a valid photo ID (driver's license, passport, etc.). If you have lost your card, your photo ID alone should be sufficient since the staff can look up your membership in their system.
Request to cancel your membership
Tell the membership counter staff that you would like to cancel your membership. They will verify your identity, confirm your membership details, and process the cancellation. The staff may ask if there is a reason, but you are not required to provide one.
Receive your full refund
Costco will refund the full annual membership fee regardless of how many months you have used. In-store refunds are typically processed immediately back to your original payment method or as cash. Your membership card will be deactivated on the spot.
Cancel Costco Membership by Phone
Call Costco Member Services
Dial 1-800-774-2678 to reach Costco's Member Services Center. The line is available during regular business hours. Have your membership number ready before calling to speed up the process.
Verify your identity
The representative will ask you to verify your membership number, name, and other identifying information. Only the primary cardholder can request cancellation over the phone.
Confirm cancellation and refund
Once verified, the representative will process your cancellation and initiate a full refund of your annual membership fee. Phone refunds may take a few business days to appear back on your original payment method.
Important: No online cancellation
Costco does not allow you to cancel your membership online through costco.com. You must cancel either in person at a warehouse membership counter or by calling Member Services at 1-800-774-2678. There is no self-service option on the website or app.
What Happens After You Cancel Costco?
You receive a full refund of your membership fee
Unlike most subscriptions, Costco offers a 100% satisfaction guarantee on memberships. You get the entire annual fee back, no matter how far into your membership year you are. This makes Costco one of the most flexible memberships to cancel.
Your warehouse access ends immediately
Once your membership is canceled, your card is deactivated and you can no longer enter Costco warehouses to shop. This takes effect right away, not at the end of a billing cycle. Plan a final shopping trip before you cancel if needed.
Executive rewards are forfeited
If you have a Costco Executive membership, any unredeemed 2% annual reward certificate will be forfeited upon cancellation. Check if you have a pending reward and redeem it before canceling to avoid losing that money.
Costco.com access is limited
Without an active membership, your access to Costco.com for purchasing is restricted. You may still be able to view products, but you will not be able to complete purchases on most items that require membership. Some non-member items like pharmacy prescriptions remain accessible.
Frequently Asked Questions
Will I get a full refund if I cancel Costco?
Yes. Costco has a 100% satisfaction guarantee on memberships. You will receive a full refund of your annual membership fee regardless of when you cancel during your membership year. This applies to both Gold Star and Executive memberships. The refund covers the membership fee itself, not purchases made at the store.
Can I cancel my Costco membership online?
No. Costco does not currently offer online cancellation. You must cancel either by visiting the membership counter at any Costco warehouse in person, or by calling Member Services at 1-800-774-2678 during business hours. The in-person method is usually the fastest since refunds are processed on the spot.
Can I rejoin Costco after canceling?
Yes. You can sign up for a new Costco membership at any time after canceling. However, Costco reserves the right to restrict re-enrollment if they determine a pattern of canceling and rejoining to abuse the refund policy. In normal circumstances, rejoining is straightforward and can be done in-store or online.
What happens to my Costco credit card if I cancel?
The Costco Anywhere Visa Card by Citi requires an active Costco membership. If you cancel your membership, Citi may close your credit card account or convert it to a different card. Contact Citi directly for details on how your specific card will be affected.
Can a household member cancel the membership?
No. Only the primary cardholder can cancel a Costco membership. Household cardholders (the free second card) cannot request cancellation. The primary member must be present in-store with their ID, or be the one calling Member Services by phone.
