Why does twenty mean location

Hi, A detective receives a message from police dispatch, asking "what's your 20? Thank you. Oui, oui. C'est "police radio code" pour where are you? Yes, it's from the days of CB radio citizen band. Click to expand As I understand it, the police borrowed the "10" code from CB users, as did the radio-taxis. In America the police have their own code, such as the one you mention but not the British police, as far as I know. There's a reference in the same article to the '10' code, apparently it did originate with the police.

Thanks very much to everybody. Very interesting. But I have another question, same kind and same context. What is the ? Context is: a policewoman introduces herself: "My name is Annie Norris. Or as I am so fondly referred to here in the old , No-Nuts Norris. Donc "What's your 20? Exemple de communication radio chez Disney en France: A: Duty manager, duty manager!

Ten-codes used to represent common phrases in voice communication were developed during the s by the Association of Public-Safety Communications Officials-International and have been widely used by police forces in the USA.

Ten-codes first reached public recognition in the mid- to lates through police-based television series and were adopted by CB radio enthusiasts. The use of 'Ten-Codes' was to standardise commonly used phrases across radio communication.

The code is 'Location'. This evolved to, "What's your twenty? The reason 'why' people use it now can be, because it is different or novel or because it offers a method of communication that is typically only understood within a particular group. When slang becomes popular enough, it stops being slang and becomes part of the language.
