FAA Towers Not in FCC Database

Search and explore antenna structures registered with the FAA for airspace safety that have no matching record in the FCC Antenna Structure Registration (ASR) database. The FAA and FCC maintain separate registries with different criteria, so the two datasets do not always overlap.

Use this page to search by address, browse towers by state, or look up a specific FAA study number. You can also filter results by structure type and FCC registration status.

Data Sources & Methodology

storage

Data Sources

The tower data presented on these pages is compiled from two federal databases: the FAA Obstruction Evaluation / Airport Airspace Analysis (OE/AAA) system and the FCC Antenna Structure Registration (ASR) database. The FAA dataset includes every structure that has undergone an aeronautical study, while the FCC dataset covers structures registered for antenna installations.

Cross-Referencing Methodology

We match FAA records to FCC registrations using a combination of ASR numbers (when present in the FAA filing), geographic proximity, and structure-height correlation. A tower is marked as “not in FCC” only when no plausible FCC counterpart is found within a tight matching threshold. Because the two databases use different coordinate systems, update frequencies, and naming conventions, a small number of false negatives is expected.

Accuracy & Limitations

Both the FAA and FCC databases are updated on their own schedules. The FAA publishes new aeronautical studies continuously, while FCC ASR bulk data is refreshed periodically. As a result, recently filed or recently dismantled structures may show temporary discrepancies. Tower counts on city-level pages depend on the city name recorded in the FAA filing, which may differ from postal or census boundaries. Aggregate statistics should be treated as close approximations rather than exact inventories.

How to Use This Data

These pages are designed for telecommunications professionals, researchers, and local planners who need a consolidated view of tower infrastructure. The “not in FCC” metric highlights structures that may warrant further investigation—either because they are exempt from FCC registration, predate the current registration regime, or were filed under identifiers that differ from the FAA record.

FAQ

What does it mean if a tower is in FAA but not in FCC? expand_more

The FAA and FCC maintain separate registries. The FAA tracks structures that could affect airspace safety through its Obstruction Evaluation process, while the FCC registers antenna installations used for communications. A tower can appear in FAA records without having a corresponding FCC registration — for example, broadcast towers under blanket exemptions, utility poles, cranes, buildings, or structures that predate mandatory FCC registration.

How is FAA and FCC data cross-referenced? expand_more

We match FAA Obstruction Evaluation records against the FCC Antenna Structure Registration (ASR) database using ASR numbers (when present in FAA filings), geographic proximity, and height correlation. A tower is flagged as "not in FCC" only when no plausible match is found within a tight matching threshold.

How often is the data updated? expand_more

Both the FAA and FCC databases are refreshed on their own schedules. The FAA publishes new aeronautical studies continuously, while FCC ASR bulk data is refreshed periodically. Our import process runs on a regular basis, so recently filed or dismantled structures may show a brief delay before appearing.

Can I search by FAA study number? expand_more

Yes. Enter a full or partial FAA study number in the lookup field and you will be taken directly to the tower detail page if a single match is found, or shown a list of matching records for partial matches.

What does the height value represent? expand_more

Heights are shown in feet Above Ground Level (AGL). We display the best available height from the FAA filing: the deterministic height first, then the "does not exceed" (DNE) value, then the proposed height.

Why are some states missing from the list? expand_more

States are shown only when there are FAA tower records available. Some states or territories may have fewer records in the FAA Obstruction Evaluation database depending on local infrastructure density and filing activity.
