10-98 Nora Exceptional
The code "98" is (probably) short for the APCO ten-code "10-98." The code "10-98" means that the responding unit has completed the call/assignment. When an officer arrives at a call/scene, the officer reports "10-97," and when the officer completes the call, the officer reports "10-98."
As for the use of "Nora," this is Riverside Sheriff’s own addition to the “10-98” code. The word “Nora” is the APCO phonetic for the letter “N.” I have no idea what is meant by the “N” at the end of the “10-98,” being that I don’t monitor Riverside; but I would guess that whatever it means, it starts with or has the letter “N.” Maybe it means something like “
nothing found,” “
no report taken,” “at the scene of an accident after investigation the officer determines there are
no injuries,” or something that corresponds to the letter “N.”
The “exceptional” part has got me stumped. “Exceptional” means having an exception, or uncommon. Maybe “[10-] 98 Nora Exceptional” means nothing exceptional to report at the end of the call.
However, the Riverside County Sheriff Department field units range from 1 to 99, so 98 could be the number of a unit. Although, it should be Watch - Unit Location - Unit Number (1 Adam 98).
If it was me, I would ask a Riverside deputy or go to a Riverside Sheriff station and inquire there.
