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.

How to cancel

  1. 1

    Choose a route.

    Visit any Costco warehouse membership counter or call 1-800-774-2678 for a live Member Services agent.

  2. 2

    Request cancellation.

    The Primary Member should identify the account and ask about the membership-fee refund under the satisfaction guarantee.

  3. 3

    Confirm billing and refund details.

    Ask about any recent renewal, the refund method, and when to expect it.

  4. 4

    Keep proof.

    Save the warehouse refund receipt or phone reference and confirmation details.

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.
