This can be especially useful when dialing an emergency telephone number – such as enhanced 9-1-1 in North America, or 112 in Europe – so that the operator can dispatch emergency services such as emergency medical services, police or firefighters to the correct location.
See on eriti vajalik kui helistatakse hädaabinumbrile, nt 911 Põhja-Ameerikas ja 112 Euroopas – sest siis saab operaator saata välja vajadusel nii kiirabi, politsei kui ka tuletõrjujad õigesse asukohta.
