Pinal County Region 9-1-1 Office

The Pinal County Sheriff’s Office 9-1-1 Coordinator is the designated administrator of the Pinal County E 9-1-1 System. Robert Woodhull is the 9-1-1 System Administrator and Laura Herrera is the Master Street Address Guide Coordinator(MSAG).

The Regional Pinal E9-1-1 System consists of five Public Safety Answering Points (9-1-1 Dispatch Centers or PSAPs), and four remote 9-1-1 sites.

The Pinal County E 9-1-1 System PSAPs are:

  • Pinal County Sheriff’s Office (PCSO)
  • Casa Grande Police Department
  • Coolidge Police Department
  • Eloy Police Department
  • Florence Police Department

The 9-1-1 remote sites are:

  • Ak-Chin Police Department
  • Kearny Police Department
  • Mammoth Police Department
  • Superior Police Department

The Pinal County Sheriff’s Office (PCSO) 9-1-1 Division plans, directs, coordinates and budgets the activities of the Pinal County E9-1-1 System. The Pinal County Region 9-1-1 Division does not accept emergency 9-1-1 calls. All 9-1-1 calls are answered by the appropriate law enforcement agency within the county.

While most of Pinal County is designated as incorporated or unincorporated, the Pinal Region E9-1-1 System comprises every entity in Pinal County regardless of community boundary or government status. The duties performed by the PCSO 9-1-1 Division affects every citizen within Pinal County whether they live, work in or travel through Pinal County.

The PCSO 9-1-1 Division duties include the development and maintenance of the Master Street Address Guide (MSAG). The MSAG is the addressing database that supports the roughly 80,000 wire line telephone numbers assigned in Pinal County. For every landline   9-1-1 call, the call is able to be routed directly to the appropriate law enforcement agency listing the telephone number and address of the caller.

For wireless (cellular) calls, the initial information provided to the 9-1-1 dispatcher is dependent on the location of the cell tower. The information sent to the dispatcher is the approximate location of the caller provided by GPS coordinates or through triangulation coordinates from cell towers.

Voice over Internet Protocol (VoIP) telephones present additional concerns for the 9-1-1 dispatcher. The 9-1-1 system relies on the customer to provide the correct address through their VoIP provider. If the VoIP subscriber moves and does not submit a change of address to the VoIP provider, their address will not be updated in the 9-1-1 system.

The Pinal County 9-1-1 System has the ability for the dispatcher to view on a map where the call is originating from.  When a 9-1-1 call is received by the dispatcher the location of the caller can be located by physical address, GPS coordinates or triangulation coordinates plots on a map of Pinal County. All addressing information will be populated on a map to provide a visual location of the caller for the dispatcher. The PCSO 9-1-1 Division works closely with multiple State, County, municipal and private agencies in order to provide accurate and up-to-date information for the protection of all citizens and visitors within Pinal County.

The Pinal E9-1-1 office is the foundation from which all correct data emanates for all law enforcement, fire and EMS agencies for the region.  The Pinal E9-1-1 office strives for 100% accuracy in its endeavors to protect the lives of citizens and vistors.
