The Airbus numbering system is an alphanumeric model number followed by a dash and a three digit number.

The model number often takes the form of the letter “A” followed by a ‘3’, a digit, then followed normally by a ‘0’, for example A320.

There are some exceptions such as: A220, A318, A319, A321 and A400M.

The succeeding three digit number represents the aircraft series, the engine manufacturer and engine version number respectively.

To use an A380-800 with Engine Alliance (EA) GP7200 engines as an example; The code is 8 for series 800, 6 for Engine Alliance and engine version 1, thus the aircraft number is A380-861.

An additional letter is sometimes used. These include:

  • ‘C’ for a combi version (passenger/freighter), 
  • ‘F’ for a freighter model, 
  • ‘R’ for the long-range model, 
  • ‘N’ for new engine option (neo), 
  • ‘M’ for a military model, and 
  • ‘X’ for the enhanced model.
  • LR: Long-range
  • XLR: Extra-long range
  • ULR: Ultra-long range
  • P2F: Passenger to freighter
