E911 Geolocation


Geolocation is the ability to determine your location by using the GPS feature in your mobile phone or your distance from cellphone towers, or Wi-Fi access points.

With geolocation, your geographical location can be shared with E911 call center staff so that they can dispatch help to where you are currently located, instead of to your Registered Location on file.

This is especially helpful with mobile devices when you are away from your Registered Location (usually at your home or your office).

First, you need to upgrade to the latest version of P3 Mobile or Z5 Mobile, for either iOS or Android.

Second, you must make sure to agree to the new end-user license agreement (EULA) in the upgraded P3 Mobile or Z5 Mobile app. You must also give permission for P3 Mobile or Z5 Mobile to use the device location (aka GPS location). If you’ve already given permission to use device location in the past (such as for Number Lookup), you won’t need to give this permission again.

You will see the new EULA and possibly the permission request for device location after you upgrade your P3 Mobile or Z5 Mobile app and launch these apps.

Once the new EULA is accepted and the permission for device location is given, then your geolocation will be automatically used when you make an E911 relay call.

Our geolocation provider was not able to process your E911 address. Please contact Customer Support to resolve the issue.

Yes. In the text chat between you and the VI, you will see the latest approximate address based on converting your GPS coordinates to the best possible street address. Your GPS will be checked periodically while you are on the E911 call to see if your location changes; if that happens, a new approximate address will appear in the text chat.

No, geolocation is only available on mobile devices*, including tablets with LTE connection or WiFi capabilities.

*mobile devices include iPhones and Android phones. Tablets include iPads and Samsung Tablet.

E911 Geolocation (Spanish)


La geolocalización es la capacidad de determinar su ubicación utilizando la función GPS de su teléfono móvil o su distancia a torres de telefonía móvil o puntos de acceso Wi-Fi.


Con la geolocalización, su ubicación geográfica puede ser compartida con el personal del centro de llamadas E911 para que puedan enviar ayuda al lugar donde se encuentra actualmente, en lugar de a su ubicación registrada en el archivo.

Esto es especialmente útil con dispositivos móviles cuando está lejos de su Ubicación Registrada (normalmente en su casa u oficina).

En primer lugar, debe actualizar a la última versión de P3 Mobile o Z5 Mobile, ya sea para iOS o Android.

En segundo lugar, debe asegurarse de aceptar el nuevo contrato de licencia de usuario final (CLUF) de la aplicación actualizada P3 Mobile o Z5 Mobile. También debe dar permiso para que P3 Móvil o Z5 Móvil utilicen la ubicación del dispositivo (también conocida como ubicación GPS). Si ya ha dado permiso para utilizar la ubicación del dispositivo en el pasado (por ejemplo, para la búsqueda de números), no necesitará dar este permiso de nuevo.

Verá el nuevo CLUF y posiblemente la solicitud de permiso para la localización del dispositivo después de actualizar su aplicación P3 Mobile o Z5 Mobile e iniciar estas aplicaciones.

Una vez aceptado el nuevo CLUF y concedido el permiso para la localización del dispositivo, su geolocalización se utilizará automáticamente cuando realice una llamada de retransmisión E911.


Nuestro proveedor de geolocalización no ha podido procesar su dirección E911. Póngase en contacto con el servicio de atención al cliente para resolver el problema.


Sí. En el chat de texto entre usted y el VI, verá la última dirección aproximada basada en la conversión de sus coordenadas GPS a la mejor dirección de calle posible. Su GPS se comprobará periódicamente mientras esté en la llamada al E911 para ver si su ubicación cambia; si eso ocurre, aparecerá una nueva dirección aproximada en el chat de texto.

No. Por el momento, la geolocalización sólo está disponible para teléfonos móviles con GPS. Estamos considerando añadir en el futuro la geolocalización a otros dispositivos como portátiles, ordenadores de escritorio, OneVP y Portal.
