Introduction
DoorDash Costco partnership has expanded to cover Costco warehouses across the United States, bringing same-day delivery of groceries, household essentials, electronics, and other merchandise to members through the DoorDash app.

The companies previously operated together in international markets, including Australia, New Zealand, Sweden, Iceland, and Puerto Rico. <Cite refs={[“turn1search0″,”turn1search1”]}/>
The announcement arrives as delivery platforms compete for a larger share of online grocery and retail spending. Uber Eats has also expanded its Costco delivery coverage, adding another major platform to the retailer’s delivery network. <Cite refs={[“turn1news12″,”turn1search2”]}/>
Background and Context
Costco is known for its warehouse shopping model, bulk merchandise, and membership-based retail business.
For years, shoppers have primarily visited physical warehouses to purchase groceries, electronics, household products, and Kirkland Signature merchandise.
The retailer has also expanded its digital shopping options through third-party delivery services. Instacart has provided Costco delivery for nearly a decade, while Uber Eats introduced a Costco partnership in 2024. <Cite refs={[“turn1search2″,”turn1news12”]}/>
DoorDash’s nationwide launch adds another delivery channel for Costco members and expands the range of retailers available through its marketplace.
Latest Update: DoorDash Costco Partnership Goes Nationwide
DoorDash and Costco announced that Costco is now available through the DoorDash Marketplace across the United States.
Members can order products from all U.S. Costco warehouses for same-day delivery, subject to local availability and applicable service conditions. <Cite refs={[“turn1search0″,”turn1search1”]}/>
What shoppers can order
The partnership includes a broad selection of Costco merchandise.
| Product category | Examples |
|---|---|
| Groceries | Pantry staples, fresh food, and other grocery products |
| Household essentials | Cleaning supplies and everyday household products |
| Electronics | Selected electronics available through participating warehouses |
| Seasonal merchandise | Seasonal products and other rotating inventory |
| Kirkland Signature | Costco’s private-label merchandise |
| Other warehouse products | More products available through local Costco inventory |
DoorDash said members can shop more than 4,000 products through the platform. <Cite refs={[“turn1search0″,”turn1search1”]}/>
How Costco delivery works on DoorDash
Costco members can place orders through the DoorDash app by selecting Costco and choosing their local warehouse.
The ordering process includes linking an active Costco membership to the DoorDash account. People who are not yet Costco members can follow a link to Costco.com to purchase a membership before returning to DoorDash. <Cite refs={[“turn1search0”]}/>
The service is designed to provide same-day delivery, although the actual delivery window and available products can vary by location.
Why DoorDash Is Expanding Its Costco Relationship
DoorDash said Costco was among the most-searched retailers that had not previously been available on its U.S. platform.
The company described the launch as a way to meet customer demand and give shoppers more flexibility in how they purchase Costco products. <Cite refs={[“turn1search0″,”turn1search1”]}/>
DoorDash’s grocery delivery strategy
The Costco launch fits into DoorDash’s broader expansion in grocery and retail delivery.
DoorDash said the addition of Costco means it now partners with eight of the 10 largest food retailers in North America, according to Progressive Grocer’s PG 100. <Cite refs={[“turn1search0”]}/>
That expansion gives DoorDash a larger selection of everyday products beyond restaurant meals.
A global partnership
The U.S. rollout builds on an existing relationship between DoorDash and Costco in Australia, New Zealand, Sweden, Iceland, and Puerto Rico.
The expansion demonstrates how delivery platforms can extend an established partnership into additional markets. <Cite refs={[“turn1search0″,”turn1search1”]}/>
Uber Eats Also Expands Costco Delivery
DoorDash is not the only delivery company expanding access to Costco.
Uber Eats announced an expansion of its Costco delivery partnership from 17 U.S. states to 47 states, making nearly 600 Costco warehouses available through the app, according to Supermarket News. <Cite refs={[“turn1search11”]}/>
The Associated Press also reported that Uber Eats and DoorDash are expanding their Costco delivery offerings as both companies grow their U.S. grocery businesses. <Cite refs={[“turn1news12″,”turn1search2”]}/>

Expert Insights and Analysis
The shift toward third-party retail delivery
The Costco expansion illustrates how warehouse retailers can use delivery platforms to extend their reach without requiring shoppers to visit a store.
For delivery companies, partnerships with large retailers create opportunities to handle larger and more varied shopping baskets.
However, the supplied announcements do not provide detailed financial results or customer adoption figures for the DoorDash Costco partnership.
Membership-based shopping remains central
Costco members must link their membership information to DoorDash to access the service.
This keeps the delivery offering connected to Costco’s membership model while allowing shoppers to use DoorDash’s ordering and delivery infrastructure. <Cite refs={[“turn1search0”]}/>
Delivery convenience versus shopping economics
Online delivery can save shoppers a trip to the warehouse, but customers should consider applicable delivery fees, service charges, tips, and any differences in product pricing.
The supplied DoorDash announcement does not specify a universal fee schedule or confirm that every product will have identical pricing to in-warehouse purchases.
Broader Implications
More competition in grocery delivery
The expansion of both DoorDash and Uber Eats into Costco delivery increases the number of platforms competing for online grocery orders.
Instacart also remains part of Costco’s delivery ecosystem, according to AP reporting. <Cite refs={[“turn1search2″,”turn1news12”]}/>
Retailers are extending digital access
Costco’s partnerships show how retailers can use established delivery networks to make warehouse merchandise available through mobile apps.
This model allows customers to combine the convenience of digital ordering with the product selection associated with a physical warehouse.
What it means for consumers
Costco members now have additional ways to order products without visiting a store.
The availability of multiple delivery platforms may also make it easier for shoppers to compare delivery windows and service conditions in their area.
