Placer Law Enforcement Numbering System

For PCSO boats, see also: Marine Ch 9, 16, 17, 71

Placer County Law agencies work under a master CAD/Radio plan administered by Placer County. Most agencies in the county are either on CAD with Placer SO, or are at least using the radio identifier protocol set by the county.

Most agencies use a standard radio identifier (sometimes dropping the first number when on their local radio net) consisting of <Number-Letter-Number>. The first number denotes the agency. The letter is the assignment of the unit. The last number is a sequential number assigned to the officer. Exception: PCSO uses a different system based upon beat assignments (explained below).

PCSO Unit Numbering System

Placer Co. Sheriff (PCSO) uses a numbering system based upon beat assignments, not officer ID’s. PCSO’s system uses a <Number-Number-Letter> series, where the first number (1) denotes agency (PCSO), the second number denotes shift/watch, and the letter denotes beat assignment.

EXCEPTION: PCSO generally fields fewer units on graveyard, and they are assigned to zones rather than beats. Graveyard zones are 1-Lower (below Newcastle/Penryn) and 2-Upper (above Newcastle/Penryn). Graveyard units will usually have callsigns of 1-Mike-1, 1-Z-2, etc.


  1. Graveyard
  2. Days
  3. Swings


A- Auburn

B- North Auburn, Foresthill Bridge

C- City of Colfax contract

D- Auburn

E- East of Colfax/ Summit

F- Granite Bay/East Loomis (east of Barton Road)

G- I80 North of Auburn to Colfax

H- Foresthill resident deputy

I- Investigator

1 David #- SRO's

K- K9 (Can also be K-#)

L- Lincoln / Sheridan

M- (Mike) Graveyard unit assigned to a zone rather than a beat (possibly second unit in zone)

N- Narcotics

O- West Roseville

P- Town of Loomis contract

R- Roseville (unincorporated) / Granite Bay

S- Sergeant

T- Traffic unit in contract cities (Loomis [Tom-1]/Colfax [Tom-2])

U- Newcastle / Penryn

W- CSO's

Z- Graveyard unit assigned to zone rather than beat - Possibly the primary zone unit

Placer County Probation uses the prefix 82 followed by three additional digits. Example, '82114' pronounced 'Eighty-Two One One Four'

If a unit assigned to a beat is a K9 unit, the "King" is added to the beat (e.g. 13 Ocean King)

Placer County Fire Department

Western Placer County (unincorporated areas) fire agencies are dispatched by two separate agencies. Fire districts are dispatched by Placer County Communications (Sheriff's Dispatch) on 154.355 (various input PL's--listed output PL). Placer County Fire Department (CDF-contract) is dispatched by CDF-Grass Valley ECC on NEU West (151.325).

Roseville, Rocklin, and Lincoln have their own dispatch centers and frequencies, while Auburn and Colfax contract with CDF, and the Town of Loomis contracts with Placer County.

All "Eastside" fire districts, along with Meeks Bay, are dispatched on NEU East (154.130 MHz) as of June 1, 2009.
