Quick answer
Costco doesn't need a receipt because every purchase is tied to your membership card. Bring the item and your membership card (or number) to any warehouse returns counter. Staff will look up your purchase instantly and process a full refund to your original payment method. The 90-day electronics window still applies, but losing a paper receipt doesn't affect your return ability at all.
Why "no receipt" isn't really a problem at Costco
Most retailers require a receipt because they have no other way to verify a purchase. Costco is different. Since you must be a member to shop there, every transaction is recorded against your membership account, whether you bought in-store, online, at the pharmacy, or at the gas station. The purchase history goes back years.
This means "returning without a receipt" at Costco isn't a special exception or workaround. It's just the normal process. The returns desk looks up your account and processes the return exactly as if you had handed them a paper receipt. You won't get gift card credit instead of a cash refund; you won't need a manager override. It just works.
What to bring
How Costco looks up your purchase
Swipe or present your Costco membership card at the returns counter. Staff can pull up your complete purchase history instantly. This is the primary method Costco uses, and it works for every in-store and online purchase made with your membership.
Outcome: Full refund to original payment method
If you don't have your physical card, providing your membership number verbally works the same way. The number is on the back of the card and on your membership email. You can also look it up in the Costco app.
Outcome: Full refund to original payment method
For online purchases, your Costco.com account shows your full order history. Showing the order on your phone or printing a confirmation provides an additional record, though the membership lookup usually finds it anyway.
Outcome: Full refund to original payment method
The Costco app shows your digital membership card, membership number, and purchase history. Using the app at the returns counter is equivalent to using your physical card.
Outcome: Full refund to original payment method
Limits to know
Costco tracks return patterns by membership account. Members with excessive return histories may have membership reviewed or revoked. Most members are far from this threshold, but it exists.
Electronics and major appliances have a 90-day return window. Even without a receipt, the 90-day limit applies from the purchase date Costco has on file.
Final sale items cannot be returned regardless of receipt status: cigarettes, alcohol, gift cards, custom orders, gold bars, and event tickets.
Diamonds over 1 carat require a Costco GIA assessment before the return is processed, even if you have a receipt.

Common questions
Can you return something to Costco without a receipt?
Yes. Costco's entire purchase system is built around your membership. Every transaction is recorded against your membership card. When you go to the returns counter, staff pull up your purchase history instantly using your card or membership number. The concept of 'needing a receipt' at Costco is largely irrelevant because the membership database is the receipt.
What does Costco give you for a return without a receipt?
Because Costco always finds your purchase through membership lookup, you always get a full refund to your original payment method, not store credit. There's no secondary 'no-receipt' outcome at Costco the way there is at Walmart or Target. If you paid with a Visa, the refund goes to that Visa. If you paid with cash, you receive cash back.
Does Costco need your membership card to process a return?
Yes, but 'membership card' is flexible. You need your membership number, which can come from the physical card, the Costco app, your membership email, or verbally. As long as staff can look up your membership, they can find your purchase and process the return.
Can someone else return an item purchased on my Costco membership?
Generally, returns must be made by the primary cardholder or a household member on the same membership. If you send someone else to return an item, they may need to be on your account. Call your local Costco ahead of time if this is your situation, as policies can vary slightly by location.
Can I return a Costco item if I gave away the box?
For most items, yes. For electronics, Costco requires all original accessories (cables, remotes, chargers) and strongly prefers original packaging. Missing the box alone may be worked around for non-electronics. Missing accessories on an electronics return is a harder problem. Call ahead before making the trip.
What if I bought the Costco item as a gift for someone else?
The original purchaser needs to be involved, since the return is tracked by their membership. The recipient can't initiate a return independently if the item was purchased on someone else's membership. One option is for the original purchaser to visit the returns counter, or for both parties to call Costco customer service to work out alternatives.
