Costco has 137 warehouses listed in California alone, yet three U.S. states still don’t have a single operating location. If you thought the warehouse giant had planted its flag everywhere, the numbers tell a different story.
Costco’s American footprint is a patchwork of abundance and absence. According to the company’s official state directory, California leads with 137 listed warehouses, followed by Texas with 49 and Florida with 35. Meanwhile, Rhode Island, West Virginia, and Wyoming have no Costco.
The contrast is striking. One state offers shoppers more than 100 locations, while residents in three others must cross state lines to shop inside a Costco warehouse.
But there’s a twist. A separate September 2026 location analysis from ScrapeHero counted 145 California warehouses, suggesting the available databases don’t perfectly align. The figures below reflect Costco’s own directory as retrieved on November 1, 2026, rather than independently reconciled totals.
So, where does Costco dominate the grocery-shopping landscape, and which states are still waiting for the warehouse doors to open?
California: 137 warehouses and a commanding lead
California sits comfortably at the top of Costco’s official directory with 137 listed warehouses. That’s 88 more than Texas, the second-place state with 49.
For California shoppers, Costco’s presence stretches across numerous cities and communities. The chain’s directory includes locations in places such as Los Angeles-area communities, Sacramento, and San Diego.
However, the precise count deserves a closer look. ScrapeHero’s September 2026 analysis reported 145 California locations, compared with Costco’s displayed 137.
The difference remains unresolved, but both sources agree on the essential point: California leads the nation in total Costco warehouses.
Texas: 49 warehouses across the Lone Star State
Everything seems bigger in Texas, and Costco’s footprint is certainly substantial. The company’s official warehouse directory lists 49 locations statewide.
From Dallas and Houston to Austin and San Antonio, Texas shoppers have multiple communities represented on the warehouse map.
Interestingly, ScrapeHero’s September 20, 2026, dataset also recorded 49 Texas warehouses, matching Costco’s displayed total at that time.
Texas may trail California by 88 listed locations, but it still holds second place in the company directory. For warehouse-shopping enthusiasts, that’s a sizable presence.
Florida: 35 warehouses keep the Sunshine State shopping
Florida claims third place with 35 warehouses in Costco’s official directory.
Its locations span the state, including Miami-area communities, Orlando, Jacksonville, Tampa, and Fort Myers.
That 35-location figure places Florida ahead of Washington’s 33 listed warehouses, though both states remain far behind California’s total.
The number is an absolute warehouse count, not a measurement of how conveniently residents can reach a location. Having 35 warehouses doesn’t mean every Florida neighborhood has one around the corner.
Still, Florida ranks strongly in Costco’s state-by-state rankings.
Washington: 33 warehouses and a long Costco connection
Washington might not be the largest state on this list, but its 33 Costco warehouses earn it fourth place in the company’s directory.
Costco has deep roots in Washington. The company began its warehouse-club journey in the Seattle area, and its headquarters remain in Issaquah.
Yet even Washington’s total comes with a counting question. ScrapeHero’s September 2026 dataset reported 35 warehouses, two more than the 33 displayed in Costco’s directory.
The discrepancy doesn’t change Washington’s fourth-place position in Costco’s published ranking. It does remind shoppers that a warehouse directory and a commercial location database may not match.
Illinois: 23 warehouses make the top five
Illinois takes fifth place with 23 Costco warehouses listed in the official directory.
The state sits behind Washington’s 33 but ahead of New York’s 21, securing its place among Costco’s seven leading states.
For grocery shoppers comparing warehouse availability, Illinois offers another example of the retailer’s concentration in certain parts of the country.
Of course, a statewide total of 23 reveals little about how far an individual shopper might need to travel. Warehouse counts don’t account for population, road networks, or where stores sit within the state.
It’s a respectable number, but convenience depends on more than a ranking.
New York: 21 warehouses with another location on the horizon
New York ranks sixth with 21 Costco warehouses in the company’s directory.
There’s also a recent development worth watching. Costco’s upcoming-locations page identified Amherst, New York, among locations scheduled for October 2026.
That announcement reflects the company’s expansion plans, but it shouldn’t automatically be added to the directory’s 21 without confirming how the company updates its totals.
For New Yorkers, the important distinction is between a location appearing on an opening schedule and a verified count of operating warehouses.
Even with that qualification, New York remains among the seven leading states.
New Jersey: 20 warehouses round out the list
New Jersey takes seventh place with 20 warehouses displayed in Costco’s official directory.
That’s just one fewer than New York’s 21, putting the neighboring states remarkably close in the ranking.
The comparison becomes even more interesting when you remember that these numbers represent entire states, not the proportion of residents living near a Costco.
Twenty warehouses in a relatively compact state tell a different geographic story from 20 spread across a much larger landscape.
New Jersey completes the top seven, leaving a wide gap between Costco’s established markets and the three states still without an operating warehouse.
Rhode Island: No Costco yet, but 2028 could change that
Rhode Island is one of three states Costco explicitly identifies as having no operating warehouse.
But the waiting may eventually end. On October 22, 2026, WPRI reported that a proposed first location was headed for Smithfield, near Routes 7 and 116.
Costco board member Helena Foulkes and local officials pointed toward a 2028 opening target.
There is an important catch. Smithfield’s planning department had not received a formal application when the announcement was reported. The project still requires planning and zoning review.
So Rhode Island’s first Costco is a reported proposal, not an operating warehouse or guaranteed 2028 opening.
West Virginia: Still waiting for its first warehouse
West Virginia has zero operating Costco warehouses, according to the company’s official careers page.
Unlike Rhode Island, which has a reported Smithfield proposal targeting 2028, West Virginia has no confirmed first-warehouse opening date in the available sources.
That leaves residents without a Costco location inside their home state.
For anyone hoping to browse bulk groceries or make a warehouse-shopping trip without crossing state lines, that absence matters.
Until Costco announces a verified opening plan, though, there’s no reliable date to circle on the calendar.
Wyoming: Another state missing from Costco’s map
Wyoming completes the trio of states without an operating Costco warehouse.
The company names Wyoming alongside West Virginia and Rhode Island on its careers website, confirming the three-state absence.
Unlike California’s 137 listed warehouses or neighboring Western states with established Costco locations, Wyoming currently has none of its own.
Available reporting also doesn’t confirm a first-store opening date.
That doesn’t mean a Costco could never arrive. It simply means Wyoming shoppers have no verified opening announcement to count on today.
For now, the state remains one of the final three blank spaces on Costco’s U.S. operating map.
The bottom line
Costco’s footprint tells a fascinating story about American warehouse shopping. California leads its official directory with 137 locations, Texas follows with 49, and Florida rounds out the top three with 35.
Yet Rhode Island, West Virginia, and Wyoming still have none.
Rhode Island’s proposed Smithfield warehouse offers the clearest possibility of change, with 2028 as the reported target rather than a guaranteed opening date.
And while different location databases disagree on some precise totals, the broader contrast remains clear: Costco’s shopping empire has a substantial presence in several states, but its map still has room to grow.
