ATC Callsign Finder

About

Callsign & ICAO Search
Search by telephony callsign (e.g. "DELTA"), ICAO designator (e.g. "DAL"), or partial name. Results show the ICAO code, IATA code, spoken telephony name, airline, country, and status — everything you need to confirm a callsign mid-transcription.

IATA Code Lookup
Enter a 2-letter IATA code to quickly resolve an airline and its ATC telephony callsign.

Aircraft Registration Search
Look up any tail number to retrieve the aircraft manufacturer, model, owner/operator, and ICAO type code.

Aircraft Type Search
Fuzzy-search aircraft models by name or type code (e.g. "Skyhawk", "A320", "C172") to get the official ICAO type designator.

Live ADS-B Exchange Integration
When browsing globe.adsbexchange.com, the extension automatically detects the selected flight's callsign and injects the official ATC telephony callsign directly into the page — no popup required.
