ICAO and IATA Aircraft Codes

One aircraft coding system, maintained by the International Civil Aviation Organization (ICAO), uses 4-character alphanumeric codes assigned to aircraft types and subtypes.

ICAO codes are used in operations by airlines and air traffic controllers. For example, a Boeing 777-300 is assigned ICAO Code B773.

The International Air Transport Association (IATA) assigns 3-character codes to aircraft as well; these are used by the geneal public, for example in airline timetables.

Boeing Customer Codes

The Boeing Company uses a series of 2-character Airline Customer Codes to identify the original-build customer for all Boeing 7x7 aircraft, up to and including the Boeing 777. The code system is not used on the 787 and the 737Max.

One example would be Emirates Boeing 777-31H. This is a 777-300 series aircraft originally built for Emirates, Boeing Airline Customer Code 1H.

Included below is a table of the Boeing customer codes used for some larger and popular world airlines.

Airbus Aircraft Numbering System

The first airliner that Airbus built was the A300, with the “A” meaning "Airbus" and 300 designating the passenger capacity.

Today, that nomenclature continues. So what, for example, what is an Airbus A320-214?

The Airbus numbering system is in the form Axxx-yyy, beginning with the "A" and followed with a 3-digit aircraft model number, e.g., A220, A319 or A380.

Following the model number is a dash and 3-digit number in this format, designating:

  • Aircraft series (e.g., 2 for a -200 or 4 for a -400 series)
  • Engine manufacturer code (see table below)
  • Engine version number
Airbus Engine Code Engine Manufacturer
0 General Electric (GE)
1 CFM International (GE/SNECMA - Safrean)
2 Pratt & Whitney (P&W)
3 International Aero Engines
4 Rolls-Royce
5 CFM International (CFM LEAP-1A for A320neo Family)
6 Engine Alliance (GE and P&W)
7 Pratt & Whitney (PW1100G for A320neo Family)


Airbus defense and military aircraft have numbers in the form "A4xx". The primary product in this market segment is the Airbus A400M Atlas.

Air France Airbus A320-214, Registration F-GLGM
Air France Airbus A320-214, Registration F-GLGM
Air Mauritius Airbus A340-313, Registration 3B-NBD
Air Mauritius Airbus A340-313, Registration 3B-NBD


One or more letters are sometimes added at the end, using the codes below. For example, A321-271NX.

  • C - combi version (passenger/freighter)
  • F - freighter model
  • N - new engine option (neo)
  • R - long range model
  • X - enhanced model
