Advanced Mobile Location (or AML) is a free-of-charge emergency location-based service (LBS) available on smartphones that, when a caller dials the local (in country) short dial emergency telephone number, sends the best available geolocation of the caller to a dedicated end-point, usually a Public Safety Answering Point, making the location of the caller available to emergency call takers in real-time. AML improves the time taken by emergency call takers to verify the location of callers and can improve the time taken to dispatch an emergency response.

AML is a protocol to transport data with SMS and/or HTTPS from the phone to the emergency call centre in all countries that have deployed AML; it is not an app and does not require any action from the caller. AML is supported in many countries, and by all smartphones running recent versions of Android or iOS, although it can be disabled in user settings.

AML was standardised by the European Telecommunications Standards Institute (ETSI) Emergency Telecommunications Subcommittee (EMTEL)[1] in 2019 as Technical Specifications.
