Why 911 Calls May Reach the Wrong PSAP

The assumption when someone dials 911 is that the call is going to the right place. Unfortunately, that is not always what happens. In some cases, a 911 call is routed to the wrong Public Safety Answering Point (PSAP), and the call then has to be transferred, introducing story-altering delays at the worst possible moment.
Understandably, people believe our 911 system can pinpoint a caller’s exact location and route the call accordingly. Door Dash knows our location for food delivery, and Uber sends their drivers to pick us up at our exact location. However, the reality for 911 is less precise.
Many 911 systems still depend on routing methods that were built in the 1960s when landlines were the norm. In those systems, calls are routed based on a cell tower receiving the call, the service area assigned to that tower, and a set of fixed rules built into the network.
In other words, the system is not always routing from where the caller actually is. It is often routing from where the system assumes the caller is. This gap is where modern 911 call misrouting begins.
Legacy 911 infrastructure was not designed to interpret changing conditions in real time. It was designed to follow established instructions. This approach, called selective routing, relies on preset routing tables and fixed jurisdictional boundaries. It does not adapt dynamically as a caller moves or as location data changes.
That model made sense in a landline world, but it makes far less sense now.
People are mobile. Calls happen near jurisdiction lines. Devices move. Situations shift quickly. Yet many legacy systems still process calls through logic that assumes stability rather than movement.
The result is predictable: sometimes the call lands in the wrong place first. When a call reaches the wrong PSAP, the impact is immediate. The call has to be transferred. The caller may need to repeat key details. Coordination between agencies can slow down. Even when everyone involved is doing exactly the right thing, the process becomes more complicated than it should be.
For call-takers and dispatchers, that added friction is not abstract. It means more complex workload, longer handling times, and more opportunities for confusion during already high-pressure moments. And in an emergency, complexity is rarely neutral. It usually comes at a cost.
Next Generation 9-1-1 was built to solve this problem.
Rather than depending on static routing rules, NG911 call routing uses a modern, IP-based framework that supports more accurate and more flexible call delivery. That includes infrastructure such as the Emergency Services IP Network (ESInet), processing through Next Generation Core Services (NGCS), and routing decisions informed by GIS data and validated location information. The system is no longer relying on old location assumptions. Precise location data determines routing decisions at the time the call is placed.
The simplest way to think about it is that legacy systems route calls based on predefined assumptions, and NG911 call routing is based on real-world conditions.
With fewer misrouted calls, there are fewer transfers, less repetition, less friction, and a stronger response chain from the first second forward. This is not just a minor improvement – it is foundational.
We have to start with a system that gets the call where it needs to go if we want better outcomes. We’re talking about NG911 call routing without detours, without delay, and without asking the people in crisis to absorb the cost of outdated routing logic.
