How Many Data Centers in the US?
3,588 Facilities Tracked

Every U.S. state hosts some data center infrastructure, but capacity concentrates heavily in a handful of markets. This directory ranks all 50 states and the District of Columbia by verified facility count, compiled from 15 source datasets. Virginia leads the nation with 418 facilities, anchored by Loudoun County's "Data Center Alley" around Ashburn, Sterling, and Manassas. Texas and California rank second and third, with Ohio close behind in fourth. Select any state in the grid below to narrow the interactive map and facility table to its locations, or open its dedicated page for operators, certifications, and city-level detail.

ITAMG tracks 1,052 named data center operators across this U.S. directory. AWS operates the most facilities (228 across 16 states), narrowly ahead of Lumen (227 across 39 states), then Microsoft (87 across 15 states). Select any operator in the grid below to narrow the map and facility table to that company's locations. All operators other than the six named hyperscale operators account for 88% of all tracked facilities, while those six (AWS, Microsoft, Google, Meta, Apple, and Oracle) represent 12%, a split that shapes where capacity growth and refresh-driven hardware turnover concentrate nationwide.

ITAMG publishes dedicated directory pages for 109 U.S. cities, including 67 markets with 10 or more verified facilities. Data center capacity clusters in metros that combine low-latency fiber, competitive power rates, available land, and concentrated enterprise demand, which is why a single county outside Washington, D.C. can outweigh entire states. Ashburn, Sterling, Santa Clara, and Dallas rank among the largest markets in the country by tracked facilities. Select any city in the grid below to narrow the map and facility table to its locations, or open its page for operator and capacity detail.

Two U.S. metro areas concentrate enough data center capacity to warrant dedicated coverage: Northern Virginia and Silicon Valley. Northern Virginia, anchored by Loudoun County's "Data Center Alley" around Ashburn, Sterling, and Manassas, is the largest data center market in this directory by facility count, while Silicon Valley is the largest West Coast cluster tracked here. Each metro aggregates several cities that behave as a single market for siting, power, and fiber decisions. Select a metro below to narrow the interactive map and facility table to its locations, or open its dedicated page for a market-level breakdown of operators and capacity.

The directory spans every state, the largest operators, and the densest metros, but a handful of pages anchor most reader journeys. The three states below host the heaviest concentrations of U.S. data center capacity, the three operators run the widest national footprints, and the two metros represent the country's primary interconnection hubs. Use these shortcuts to jump straight to a fully detailed page, or return to the filters above to explore the full dataset by state, operator, city, or certification.

ITAMG compiles this data center directory through a multi-source entity resolution process. Raw facility records from 15 source datasets are ingested, normalized, and deduplicated using a 4-tier matching algorithm (Google Place ID matching, address normalization, coordinate proximity, and name/operator similarity). Where a facility hosts multiple providers, the Index reports the facility operator, which may differ from a provider named in the facility's name. Each merged facility receives a confidence score (0-100) based on source count, address verification quality, operator confirmation, data richness, and source authority. Only facilities scoring 20 or higher and passing a data center classification filter are included in the public database. Unlike other data center lists that rely on a single directory, this database cross-checks facilities wherever more than one of its source datasets reports them. This verification-first approach is deliberately conservative: records that cannot be independently confirmed and located are excluded rather than counted, so the totals published here may read lower than other sources on the internet. That tradeoff is intentional. Every published count favors verifiable accuracy over volume. The data center locations database is updated periodically as new data becomes available.
