The Q-code is a list of signals abbreviating a detailed question or answer. The code, as agreed upon by the International Telecommunication Union, is used worldwide on radiotelegraph. The meanings assigned to the Q-code abbreviations may be amplified or completed by the addition of other groups, call signs, place names, figures, numbers, etc. It is optional to fill in the blanks shown in parenthesis. Any data which is used to replace the blanks shall be sent in the same order as shown in the text of the following tables.

Q-code abbreviations are given the form of a question when followed by a question mark. When an abbreviation is used as a question and is followed by additional or complementary information, the question mark should follow this information.

A master list of Q-Codes can be found  in Appendix 9 to the Radio Regulations Annex to the International Telecommunications Convention (Atlantic City) 1947, for blocks QRA to QUZ inclusive, and in ICAO publications Dec 6100-COM/504/1 for blocks QAA to QNZ inclusive.
