Airline Coding Directory
The Airline Coding Directory (ACD) is the official industry source for airline designators, three-digit airline numeric codes and location identifiers. It also includes ISO currency, country codes, lists contacts for Minimum Connecting Time (MCT), coordinators and airlines applying reconfirmation procedures, as well as the Numeric Location Type Code.
ACD Table of Contents (pdf)
The ACD was printed for the last time in 2012 as we moved to a Windows-based application (eACD). From 2016, the eACD is only available in an efficient web downloadable version.
Please note that the monthly bulletins are now only available with the eACD which is valid from June to May annually.
Who uses it
- Original Equipment Manufacturers (OEMs)

This improved application has all the information available in the printed version. In addition, it now features an update function which allows monthly updates that includes, not only the bulletins, but also a complete refresh of the coding tables & directory making your searches more accurate. The industry therefore benefits from 12 updates per year, compared to two previously. It is available as a single user license only; searching codes has never been easier!
