A plus code is like a street address for people or places that don't have one.

Plus codes give addresses to everyone, everywhere, allowing them to receive deliveries, access emergency services, register to vote – and more.

Plus codes are short, simple, and easy to use: X4HP+M5, Cairo, Egypt, for example. These codes can be used on Google Maps to get directions to a home or business. https://plus.codes/ There's an AP/library for python, ruby, swift, java, rust... https://github.com/google/open-location-code
