COM 4.1 ALPHA – NUMERIC CALLSIGNS

The concept of call sign confusion and particularly the use of alphanumeric call signs are investigated by IFATCA.


IFATCA Policy is:

An alpha-numeric call sign is defined as:

An alpha numeric call sign is one where the suffix consists of:

  • number(s) followed by one or more letters; or
  • number(s) followed by a combination of letters and numbers.

See: Resolution B16 – WP 98 – Amman 2011

IFATCA Policy is:

To reduce the possibility of call sign confusion:

  • Call signs that correspond to the last two designators of both ICAO and IATA airport designators shall not be used.
  • In alphanumeric call signs, aircraft operator designators shall not be chosen that will create confusion with phonetic letters.
  • The use of tools that reduce possible call sign similarity shall be encouraged
