Amateur Radio Relay League (ARRL)

ARL Radio Numbers

Numbered messages have been established for some of the more common texts sent during emergencies and holiday seasons. When this common text can be used, an ARL NUMBER is substituted for the text and sent. The delivering station reads the actual text to the address, not the ARL NUMBErsRs.

The letters ARL are inserted in the preamble in the check and in the text before spelled out numbers, which represent texts from this list.


When delivered to the recipient it is read as “Have a wonderful time. Let us know when you return.”

There are also some ARL Numbers with placeholders. The filler will be listed after the ARL number. Example:
This message would be delivered as “Congratulations on your HIGH SCHOOL DIPLOMA, a most worthy and deserved achievement.

There are 2 major groups of ARL Numbers
