How to Cancel Costco
To cancel a Costco membership, the Primary Member can either visit a membership counter at any Costco warehouse or call Member Services at 1-800-774-2678 to speak with a live agent. Costco says an in-warehouse cancellation includes an immediate refund. See Costco’s official membership cancellation instructions before you begin.
Costco also states that it will cancel and refund a membership fee if a member is dissatisfied. Its policy describes this as a 100% satisfaction guarantee for memberships. Read the current Costco return and membership policy if you need to discuss a refund request.
Before you cancel
Who can cancel
The Primary Member must request cancellation. Have the membership number ready; a membership card and photo ID can help at a warehouse.
Online limitation
Turning off Auto Renewal online is different from cancelling the membership. Costco lists warehouse counters and live phone agents for full cancellation.

Refunds, Auto Renewal, and billing issues
Membership-fee refund
Costco says it will cancel and refund the fee if you are dissatisfied. This guarantee does not automatically refund merchandise or other orders.
Refund timing
Warehouse cancellation includes an immediate refund. For phone cancellation, ask the agent for the posting timeline.
Stop Auto Renewal
Annual fees renew on the first day of the renewal month. Remove Auto Renewal at least two business days before that month if you want the membership to expire.
Unexpected renewal charge
Save the setting-change or cancellation date, confirmation, and agent reference. Contact Member Services to compare them with the charge.
After the cancellation request
Check your account activity after the request, especially if you used a credit card for Auto Renewal. Compare the date of the cancellation with the date of any renewal charge. If something does not match what the representative explained, call Member Services and provide the details you saved.

Frequently Asked Questions
What documents do I need to cancel my Costco membership?
Costco’s cancellation page identifies the Primary Member as the person who can request cancellation. It does not publish a detailed required-document list on that page, but bringing a membership card and photo ID can help verify the account at a warehouse.
How long does a Costco membership refund take?
Costco states that a cancellation at a warehouse membership counter receives an immediate refund. For a phone cancellation, ask the live agent how the refund will be issued and when you should expect to see it.
What happens if I remove Auto Renewal but do not cancel?
Your membership can expire instead of renewing if you remove Auto Renewal at least two business days before the renewal month. Removing Auto Renewal does not itself close the account or replace a cancellation request.
