Police Code 418 & 427 meaning?

What do the codes 418 & 427 mean to police? It’s the title of the new csi episode so I was just wondering 🙂

  1. Depends on what code system they’re using. See if these make sense in the context of the episode:

    418 = MIssing Person

    427 = Kidnapping.

    The link below is to a list of the IDF codes used by Las Vegas Metro PD.

  2. Area Code 427

  3. Area Code 418

  4. 1

  5. The sources I research indicate a Code 418 is a missing person. A Code 427 is kidnapping.

    One thing some don’t understand is not all agencies have the same coding system if one is used at all.

    Also, CSI, although fictional, most likely gets a lot of it’s ideas and police jargon from the Miami, New York, and Las Vegas areas.

    The phenetics also vary from area to area. From the answers given so far, they are different from in the agencies those people work for, and where i work. Not extremely different, just a letter or two. The 10 codes vary greatly from area to area. For example when training occurs involving neighboring agencies, the 10 codes are extremely different. A city less than 7 miles from mine has very different 10 codes. For another example, someone answered that a “standard” code for 10-33 is “emergency.” In the city I work for, 10-33 is a burglary alarm. Also a list of 10 codes for an angecy would be far to long to put on Yahoo answers. They often include 10 and 11 codes.

  8. The “10-code”s vary. Some basic ones which are fairly common are “10-4” (affirmative) and “10-33” (emergency). Apart from that, they vary wildly. This was a big problem during 9/11 when several law enforcement agencies came together on one radio network and crisscrossed conflicting 10-codes. One reasonable policy that came out of 9/11 and FEMA was a move to use plain language instead of “jargon”. As you can see, things haven’t changed much.

  9. It depends where the CIS headquarters are portrayed to be. The police codes could be the state statute or local police ordinance number corresponding to the case to be investigated. If the CIS show is suppose to be in California. Then the numbers would mean the penal code used by Law Enforcement in California.
