Costco has expanded its delivery partnerships with Uber and DoorDash, bringing nationwide delivery coverage through both e-commerce platforms.

The move extends the wholesaler's existing relationships with the two delivery providers. Costco shoppers increasingly respond to same-day delivery options, and the company is scaling its third-party partnerships accordingly.

For marketing and e-commerce teams tracking grocery and warehouse-club channels, the expansion signals how large-format retailers are leaning on established delivery networks rather than building last-mile infrastructure in-house. Same-day delivery has become a key capability for the wholesaler as shopper expectations shift.

The nationwide rollout means Costco members and shoppers across the US can now order through Uber and DoorDash in markets previously outside the companies' delivery footprint with the retailer.
