As app-based grocery delivery continues to expand across the U.S., major retailers are adding new partners to reach more households. Costco is the latest to widen its delivery footprint, announcing a national expansion with Uber Eats that members across most of the country are now poised to notice. The change adds another ordering option beyond Costco’s existing same-day setup and reaches far more states than before.
Costco broadens its delivery partnership, reaching 47 states
Costco and Uber announced on September 16, 2026, that Costco delivery through Uber Eats is expanding to 47 states, up from 17, according to Uber’s investor relations statement and reporting from the Associated Press. The companies described the move as a major national expansion of their U.S. partnership, putting Costco on Uber Eats for millions more potential customers. That is the clearest verified scale attached to the change so far.
The expansion means Costco members in newly added coverage areas can place orders through Uber Eats from participating U.S. Costco stores, rather than relying only on in-store shopping or Costco’s existing web-based delivery channels. Uber said Uber One members also qualify for no Uber fees on eligible grocery and retail orders over $60, a benefit tied to the platform rather than Costco membership itself. Costco has long offered delivery in other forms, but this announcement specifically changes the app landscape members will see.
Costco’s own customer-service materials show that same-day grocery delivery has already been powered by Instacart, while 2-day grocery delivery remains available nationwide except in Alaska, Hawaii, and Puerto Rico. This new expansion does not replace those services in the company’s published materials. Instead, it adds a broader Uber Eats option that members in most states may now encounter alongside Costco’s existing delivery programs.
Members nationwide will see broader access, but some details are still limited
For shoppers, the most immediate impact is geographic. Uber said the service is now available in 47 states, which makes this a near-national change rather than a limited regional test. The companies have not, however, released a comprehensive public list of every affected warehouse or every newly added city.
That leaves some local questions unresolved. Costco has not published a full warehouse-by-warehouse map tied to the September 16 expansion, and neither company has publicly detailed which specific metro areas were added first within each state. What is confirmed is the state-level scale: the service moved from availability in 17 states to 47 states, making access substantially broader than it was before.
There are also still differences between Costco delivery channels. Costco’s same-day service pages state that a $35 minimum order applies for qualifying ZIP codes, while help materials also note that long-distance orders may carry a higher minimum and an added fee. Members in areas newly covered by Uber Eats should expect broader app availability, but not necessarily identical pricing, fees, or inventory across every delivery option.
The shift reflects intensifying competition in grocery delivery
The timing reflects a larger competition for grocery orders. The Associated Press reported that DoorDash and Uber Eats have both been expanding their U.S. grocery businesses, and Uber said Costco had been one of the most-searched retailers not yet widely available on its U.S. platform. That helps explain why both companies framed the rollout as a significant national growth move.
Costco’s existing delivery model also provides context. Company customer-service pages continue to separate same-day delivery, which is powered by Instacart, from other shipping methods and from nationwide 2-day grocery delivery. In other words, Costco is not entering delivery for the first time; it is broadening how customers can access delivery and through which platform they place those orders.
For members, the practical result is straightforward. More Costco shoppers across the continental U.S. are likely to see Costco appear in Uber Eats where it was not previously offered, while Alaska, Hawaii, and Puerto Rico remain outside some of Costco’s broader delivery coverage in published company materials. The companies have not announced a narrower end date for the expansion, indicating that this is a continuing service change rather than a temporary promotion.
