About CellTowerLookup

What the site is for

Type an address, ZIP code, city or county and see the cell towers around it: who owns each one, how tall it is, what kind of structure it is, whether it has to be lit for aircraft, and which carriers phones have reported on it. You can also browse towers by state, county, carrier and 5G city.

It can help explain a weak signal, identify a tower you've noticed down the road, or show which carriers have been reported in a place before you move there.

Where the data comes from

The map currently holds 283,430 sites: 183,940 structures registered with the FCC and 99,490 approximate cell sites that phones report but that have no registered structure nearby.

• FCC Antenna Structure Registration (ASR): locations, heights, structure types, owners and lighting. The current catalog was built from the FCC's weekly file downloaded October 11, 2026, keeping every structure not marked as dismantled.
• OpenCelliD: crowdsourced reports of the cells phones see, with the carrier's network code and radio technology (LTE, 5G NR and older). We use the U.S. files downloaded in April 2026 and match each reported cell to the nearest registered structure within 200 meters. Licensed CC BY-SA 4.0 by Unwired Labs.
• GeoNames: ZIP code centers, towns and counties, used to place towers and build the ZIP pages. Licensed CC BY 4.0.

How the two datasets are joined, and what each one can't tell you, is on How it works. The full list of sources is on Sources.

Independent

CellTowerLookup.com is an independent site. It is not affiliated with, endorsed by or funded by the Federal Communications Commission, OpenCelliD, any wireless carrier or any tower company. A carrier listed on a tower means phones reported that carrier's cell there; it is evidence, not a lease record. For official registration records, use the FCC's own Antenna Structure Registration search.
