Gather your membership info
Have your Costco membership card and a valid government-issued photo ID ready. If canceling by phone, locate your membership number (printed on your membership card or accessible at costco.com under 'My Account').
Choose your cancellation method
Costco does not allow online cancellation. You must cancel either in person at any Costco warehouse membership counter, or by phone at 1-800-774-2678 (Member Services). Phone lines are available during regular business hours.
Go to the Membership Counter (in-person) or call Member Services (phone)
In-person: Walk to the 'Membership' counter near the warehouse entrance — do not go to a regular checkout lane. Phone: Call 1-800-774-2678 and say 'cancel membership' when prompted by the automated system to reach a representative.
Verify your identity
In-person: Present your membership card and photo ID to the membership counter associate. Phone: Provide your membership number, full name, and address to verify identity. Only the primary cardholder can request cancellation.
Request cancellation and confirm refund
Tell the associate or phone representative: 'I'd like to cancel my membership.' They will confirm your account details and process the cancellation. You are entitled to a full refund of your annual membership fee regardless of how much time remains in your membership year.
Receive your refund
In-person: Refund is issued immediately, typically returned to the original payment method or as cash/check. Phone: Refund is returned to the original payment method and typically takes 5–7 business days to appear.
