1. Since 2022 the registration suffix may contain the numbers 2 to 9, so long as the combination contains at least one letter.
2. Only C-F, C-G, C-I & CF- are allocated in Canada.
3. Since 2018 the suffix may contain letters in last 2 positions. In this scheme the digit immediately after the dash indicates the type of aircraft. e.g. 2 for Boeing and 3 for Airbus.
4. Does not figure in the ICAO document "AIRCRAFT NATIONALITY MARKS, NATIONAL EMBLEMS AND COMMON MARKS".
5. F-O is for aircraft based outside mainland France, but aircraft may also retain mainland F-B, F-G or F-H series.
6. Any combination of 3 to 5 letters and numbers permitted (except the letters "I" or "O" are not permitted when the suffix contains numbers).
7. Besides the United Nations, intergovernmental organizations (IGOs) such as the European Union and NATO do not have the power to create aircraft registrations.
