To cancel a Costco membership, the primary member can visit a membership counter at any Costco warehouse or call Member Services at 1-800-774-2678 and speak with a live agent. To downgrade, ask at a warehouse membership desk or call the same number; Costco says these changes cannot be completed online or through live chat.
How to cancel a Costco membership
- Go to a warehouse: The primary member can ask at the membership counter at any Costco warehouse. Costco says the counter can provide an immediate refund. Use Costco’s warehouse locator to find a location.
- Call Member Services: The primary member can call 1-800-774-2678 and speak with a live agent. Costco does not specify a refund timing for cancellation requests made by phone.
Costco’s cancellation guidance, published July 24, 2025, identifies the primary member as the person who can request cancellation. If you are an additional household cardholder, have the primary member make the request. (Costco: How can I cancel my Costco Membership?)

If you have an Executive membership, ask the agent or membership-desk employee to explain how your current upgrade fee and any issued or accrued 2% Reward apply to the specific cancellation or downgrade you are requesting. Costco’s indexed help result says an Executive member must cancel or downgrade to Gold Star or Business to receive a refund of the current upgrade fee, and that rewards may be subtracted from that refund and forfeited to the extent they exceed it. The result does not establish an individual member’s refund amount, so ask Costco to calculate yours before proceeding. (Costco Executive 2% Reward FAQ)
