10-codes
If your listening to the city of myrtle beach they use the national ten codes, like:
10-17 meet complainant
10-27 license check
10-28 check tag
10-29 warrents
10-38 makeing vehical stop
10-70 fire
10-76 enroute
I think the last place I saw an actual hard copy was in the back of a police call book at like radio shack.
Oh and by the way horry county uses the SC ten codes which are yet different. Like instead of going 10-38 they are 10-48, 10-17 is enrout.
Hope that helps.
