20

part of a series of '10-codes' that many security officers & law-enforcement-types use, the '10-20' code refers to receiving a location coordinates from a second party at the other end of the line (over distance radio transmission). '10-4'- meaning that the transmission has been received.

"Soldier.. what's your 10-20?" often shortened to: "what's your 20?"
