How It Works

This actor queries the FCC Universal Licensing System (ULS) API via direct HTTP requests. No browser, no scraping, no authentication. The FCC provides this data as a public service covering all FCC-issued licenses: amateur radio, commercial land mobile, broadcast TV/radio, cellular, microwave, and more.

FAQ

What types of licenses can I search? All FCC license types: amateur radio (ham), commercial land mobile, broadcast (TV and FM/AM), cellular/PCS, microwave, maritime, aviation, and more.

Do I need an API key? No. The FCC ULS API is completely open — no registration or authentication required.

What is the maximum number of results? 5,000 per query. For broader searches, use state or license type filters to break results into manageable chunks.

How current is the license data? The FCC ULS database updates daily. New licenses and renewals typically appear within 24-48 hours of FCC action.

Limits & Rate Limits

• Maximum 5,000 results per query
• FCC does not publish official rate limits, but excessive requests may result in temporary throttling
• At least one search parameter is recommended — queries with no filters return too many results to be useful
• Frequency search accepts MHz values; the API matches against the center frequency of the licensed band
