what3words has collaborated with South African non-governmental organisation (NGO) Gateway Health Institute, to get some 54,000 residents of an impoverished informal settlement, on the map. With a mobile address printing machine and a team of local field workers, what3words and Gateway Health Institute addressed hundreds of homes in KwaNdengezi, a township on the outskirts of Durban, over the first two days. The project gives residents access to medical services such as ambulances and medicine, and has provided them with a medical record for the first time. Almost half (45%) of the 18.7 million adults in South Africa live in townships or informal settlements. Homes in these informal settlements have no formal addresses, leaving those who live there invisible to the system. Residents can’t order goods or receive deliveries, and they struggle to access basic utilities, amenities and medical care.
