Costco closed on Memorial Day

Costco’s U.S. warehouses are closed on Memorial Day, May 25, 2026, according to the company’s customer-service and holiday-closures pages. The closure applies to warehouses in the United States and appears on Costco’s list of annual holiday shutdowns. Costco’s customer-service page also says its membership, warehouse and online-order phone and chat lines are closed for Memorial Day. (customerservice.costco.com) The closure matters for shoppers making last-minute holiday runs for groceries, drinks or grilling supplies. (customerservice.costco.com) Costco directs members to its warehouse locator to check local details, including service hours and holiday closures, before heading out. (costco.com) ### Is Costco actually closed on Memorial Day this year? Costco’s customer-service page says “May 25, 2026 (Memorial Day): Closed” for membership and warehouse phone support, online-order support and several other services. Costco’s separate holiday-closures page says U.S. warehouses are closed on Memorial Day. The company’s holiday-closures page does not describe Memorial Day as a reduced-hours day. (customerservice.costco.com) It lists the holiday as a full closure for U.S. warehouses. ### Which Costco operations are affected besides the warehouse floor? Costco’s May 18, 2026 customer-service posting says Memorial Day closures also apply to Costco.com online-order support, membership and warehouse support, Costco Business Center orders, technical and warranty services, the mail-order pharmacy and Costco Travel phone support. (costco.com) Costco’s hours page says warehouse services such as the gas station, pharmacy and optical department should be checked through the specific warehouse listing. (customerservice.costco.com) The company says the locator will show adjusted holiday hours and closures for a selected location. (customerservice.costco.com) ### Is every Costco location covered by the same Memorial Day rule? Costco’s holiday-closures page says “Our U.S. warehouses are closed” on Memorial Day, which indicates the policy applies nationwide in the United States. The warehouse-locator page adds that shoppers should select their local warehouse to see “hours and upcoming holiday closures.” Costco’s hours-of-operation page says the same tool shows adjusted holiday hours for warehouse services, which can vary by location and department. (customerservice.costco.com) ### Where should members check before making a trip? Costco’s warehouse-locator page tells members to find and select a local warehouse to see hours and holiday closures. (customerservice.costco.com) The customer-service “Find a Warehouse” page repeats that instruction and routes users to self-service support options. The company’s hours-of-operation page says service counters do not always follow the same schedule as the main warehouse and instructs customers to review the “Store Details” section for the chosen location. (customerservice.costco.com) ### What holidays does Costco close for each year? Costco’s holiday-closures page lists seven annual U.S. warehouse closure dates: New Year’s Day, Easter Sunday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. (costco.com) Costco’s locator page says local listings will show upcoming holiday closures, and the company’s customer-service pages remain the clearest source for whether a holiday is a full closure or a modified-hours day. (costco.com) On May 26, 2026, members can again use the warehouse locator and regular customer-service channels to confirm reopening hours for their local store and its departments.
