What this tracks
This dataset maps the boundaries of Tennessee’s Public Safety Answering Points (PSAPs), which determine where 911 calls are routed for emergency response.
Why it matters to you
When you call 911 in Tennessee, this data decides whether your call reaches county sheriffs, city police, or regional dispatch centers. Knowing your PSAP boundary tells you which agency will initially respond if you report a car crash on your commute or a break-in at your business. These boundaries sometimes follow unexpected lines, especially near city/county borders.
How to read this data
DsplayName — The agency handling 911 calls for that area (e.g., “Anderson County Sheriff Office”). This is who answers when you dial for help.
Shape__Area — Technical field showing the geographic size of the PSAP boundary in square units (not meaningful for residents).
Where this leaves you
This dataset doesn’t let you look anything up by your address, but it’s still a window into how the state operates. Read it to understand the scope of the program and what the official records contain; the state’s own interactive map (linked on this page) shows the locations involved.
