Airline Coding Directory and Location Identifiers (ACD)
The Airline Coding Directory (ACD) is the only official source for IATA airline and location codes. The directory is updated daily with all the latest modifications so that you can rely on the most up-to-date data to power your operations.
ACD data is split into two categories:
- Airline Designators contain data on all IATA airline codes (airline designators, accounting codes, prefix codes, etc.). Airline Designator Codes are used as a single point of reference for reservations, schedules, timetables, telecommunications, cargo documentation, legal, and other aviation and travel-related purposes. Airline accounting codes and airline prefixes are also essential for the identification of passenger and cargo traffic documents, processing of passenger accounting transactions, cargo transactions and other financial and accounting purposes.
- Location Identifiers contain data on IATA location codes (for airports as well as intermodal / ground transport location and cities). Location Identifiers are used as a unique identifier for worldwide airports and travel locations that have commercial air or intermodal travel options.
