How many data centers are in the US?

Nobody can answer that from public records, and this page will not pretend to. What it can say is that 1,956 US data centers appear in the two open sources behind it: county and city permit GIS (927) and OpenStreetMap (1,791). Treat it as a lower bound. There is no federal register of data centres, so any single number you see for how many data centers are in the USA is an estimate.

Where can I find a data center map of the USA?

The map above. Every dot is one facility at the coordinate its source published, so the data center locations map is as complete as those sources are and no more. Zoom into a metro to see the individual sites; pick a state below for its own map. The state data center maps are drawn from the same records as this one.

Are there data centers near me?

Pick your state from the list below and the city roll-up on that page will show the nearest cluster, including the data center closest to a given address. This site does not read your location, so "data centers near me" is answered by the state and city tables rather than by geolocation.

Data center, data centre or datacenter — does the spelling matter here?

No. Whether you write data center, data centre or datacenter, this is the same directory and the same records. The sources use all three spellings and none of them is treated as a different kind of building.

Where are AI data centers located?

Public records almost never label a building as an AI data centre — the permit says "data center" and the tenant and workload are not disclosed. That means no honest source can tell you how many AI data centers are in the US, where AI data center locations are, or whether there are AI data centers near me, and this directory does not pretend to. It makes no AI/non-AI split at all. What it can show is where the new supply is: Virginia carries 843 of the 1,956 records here.

What is the largest data center in the USA?

Of the facilities with a published floor area, the largest here is Wilderness Crossing in Virginia at 5.0M sq ft. Floor area is only published by a handful of county layers, so this ranks the large data centers that disclose it, not the country.

How current is this and what is missing?

The OpenStreetMap extract is from 2026-09-17; the county permit archive was captured 2026-09-12. 6 states have no record in either source — that means nothing has been published there, not that no data centre exists.

US data center map and directory

Every data centre this site can cite a public record for: 1,956 facilities in 48 states, mapped across the United States and listed by state. 927 come from county and city permit GIS layers, 1,791 from OpenStreetMap. It is a floor on what exists, not a census — no complete public roster of US data centers exists to copy.

Every state with at least one facility on the public record, most first.

States with no public roster yet

No county or city in these states publishes a data-centre GIS layer, and OpenStreetMap has no tagged facility in them. That is an absence of records, not an absence of data centres, so no page is minted for them.

Contributor-maintained. It is a floor on how many data centres exist in a state, never a census, and coverage varies sharply between metros.

As of 2026-09-17 · www.openstreetmap.org · Open Database License (ODbL)

No complete public roster of US data centres exists. This directory is the union of two open sources and is a floor, not a count. Nothing here is modelled, extrapolated or filled in for a state that publishes nothing. Records within 200 m of each other across the two sources are folded into one; 762 were folded this way.
