ADS-B ICAO24 to Country & Registration

Determines an aircraft’s country and registration number from its 24-bit ICAO address using three strategies.

Markdown Python

Overview

This tool translates a 24-bit ICAO hex address (Mode S) into the corresponding country and registration number. It applies three approaches in a pipeline: algorithmic decoders (for specific national schemes like TC-XXX, N-numbers, etc.), a tie-up database of 516K+ entries for precise hex‑to‑registration mappings, and a range lookup to determine the country from ICAO24 address blocks. Results include a confidence score and support batch processing.
