Can You Return an Open Item at Costco Without a Receipt?
Yes, in many cases, you can return an open item to Costco even if you no longer have the receipt. Costco offers a 100% satisfaction guarantee on most merchandise, and its official customer service guidance says that having the receipt or original packaging can help, but it may not be necessary to process a return.
However, Costco’s return policy has important exceptions and time limits for certain products. Before heading to the warehouse, it is worth knowing how the process works.
Can You Return an Open Item Without a Receipt?
Generally, yes. If you are a Costco member and you are not satisfied with a product, you can take it to the returns counter at any Costco warehouse.
Costco says that customers should bring the product to the warehouse and speak with the Member Services Team. A receipt or original packaging can make the process easier, but Costco states that it may not be necessary to complete the return.
This means opening the package or using the product does not automatically make it ineligible for return.
What If You Lost Your Costco Receipt?

Losing your paper receipt does not necessarily mean you cannot return the item.
Costco keeps purchase information associated with member accounts. Members can view many in-warehouse purchases through Costco.com by going to Orders & Returns and selecting the In-Warehouse tab. Costco says purchase receipts can be available for up to two years, although some types of purchases are excluded from online warehouse purchase history.
If you cannot find the receipt online, you can still visit the warehouse’s Member Services or returns counter and ask for assistance.

If you bought a product and later discovered that you were unhappy with its quality, performance or suitability, you can generally take it back and explain the reason for the return.
That said, Costco’s return policy has specific exceptions. Some products have special return conditions or limited return periods, so an open package does not guarantee that every item will be accepted.
