Open Aviation Data

The Guardians of The Codes

AirTrack maintains two free, openly published aviation reference datasets — the ICAO 24-bit hex allotments table and a world registry URL directory. We keep them accurate, we keep them public, and we don't put them behind a paywall. Consider it our contribution to the planespotting community.

ICAO Hex Allotments
The full ICAO 24-bit Mode S address block table — 188 countries, sourced from ICAO Annex 10 Volume III Appendix to Chapter 9 (Table 9-1). Each entry includes the country name, ISO code, aircraft registration prefix, hex start/end, and block size. This is the definitive reference for matching a Mode S address to a country of origin.

World Registry Directory
Official civil aviation registry URLs for 81 countries worldwide. Each entry includes the country name, ISO code, registration prefix, and the direct URL to that country's official aircraft register. Useful for developers, researchers, and aviation enthusiasts building their own tools.
