The message number is selected by the station originating the message and it must be on all messages. It stays with the message all the way to the point of delivery. The delivering station may need to reply to the station of origin and refer to this number.

Use number digits only; no letters, leading zeroes, or punctuation spelled out or otherwise. Numbers are usually begun with 1 at the start of a year or month at the pleasure of the originating station.

NOTE: If the message is a SERVICE message, place letters SVC, followed by a space, in front of message number as a leading group (infrequently used currently). Precedence is kept the same as in the message being serviced. (See the section on creating service messages.
