What an FCC ASR record tells you

Each tower profile combines registration status, structure height, ground elevation, owner information, FAA study details, and geographic coordinates. ASR data covers structures subject to federal registration requirements—it is not a complete inventory of every cellular antenna or carrier installation.

How to look up a cell tower or antenna structure

Use the path that matches what you already know. Search directly when you have a number or name; browse geographically when you are researching a location.

Search an ASR number

Enter the seven-digit number with or without “ASR.” This is the fastest route to one structure’s specifications and reported registrant.

Search an owner

Enter a company or organization name to surface matching registrations. Remember that the registrant may own the structure while several unrelated tenants use it.

Browse a county

Choose a state and county to see registered locations together, filter the tower list, and compare height and ownership patterns.

Use your location

The near-me tool matches your device to the closest indexed county and calculates approximate straight-line distance locally in your browser.

FCC tower lookup versus a carrier coverage map

These tools answer different questions. A carrier map estimates where a network may provide service. An ASR lookup identifies a federally registered physical structure and the information filed for it. The registration record does not list every radio, technology, or carrier currently installed at the site.

This distinction matters when researching poor signal. The nearest registered tower may belong to a broadcaster or may not host your carrier. Conversely, the antenna serving your phone could be on an unregistered rooftop, utility pole, or small-cell installation that is absent from the ASR data.

How tall are registered antenna structures?

Heights vary from modest support structures to broadcast towers approaching 2,000 feet. This directory reports overall height above ground in feet and meters when available, plus ground elevation and an approximate overall elevation above mean sea level. Height describes the structure—not necessarily the mounting height of a particular antenna.

Who owns the tower?

The owner or registrant field identifies the entity associated with the FCC registration in the imported bulk data. Entries can include dedicated tower companies, broadcasters, utilities, public agencies, wireless companies, and local organizations. A carrier name on a structure is not guaranteed, and a tower owner is not the same as every network leasing space there.

If ownership matters for a lease, easement, legal notice, acquisition, or engineering project, use this directory as a research starting point. Confirm the current FCC filing and consult county property records or qualified professionals before relying on an identity or mailing address.

Why some towers are not listed

The FCC does not require every communications installation to have an ASR number. Registration depends on factors such as structure height, location, and potential effect on air navigation. That is why a complete-looking neighborhood map can still omit rooftop antennas, distributed antenna systems, and many shorter cellular sites.

Tower lookup questions

How can I look up an FCC tower by ASR number?+

Enter the registration number with or without the ASR prefix in the search field. The matching tower page provides the registered height, coordinates, owner information, dates, and filing identifiers available in this directory.

Can I find who owns a cell tower?+

You can find the registrant or owner name reported in an FCC ASR record. The ASR owner is not necessarily every carrier or tenant using the structure, and ownership should be confirmed for legal or commercial decisions.

Does Antenna Registry show every cell tower?+

No. It indexes active records from the FCC Antenna Structure Registration files. Many rooftop sites, small cells, and shorter structures do not require an ASR registration and will not appear.

How accurate is the near-me distance?+

The near-me tool uses the Haversine formula to estimate straight-line distance between your browser location and registered coordinates. It does not measure road distance, signal strength, or carrier coverage.
