Plus Codes, officially Open Location Code (OLC), is a geocoding system that encodes geographic coordinates into short alphanumeric codes. Developed by Google, it was released as an open-source project to provide a universal method for identifying locations that lack traditional street addresses. A Plus Code can identify any place on Earth and can be used to share locations via maps, signage, or text, including in areas with limited addressing infrastructure or offline environments.

How it works: The global grid divides the world into cells, and each code represents a specific area. A typical code consists of a district area portion and a local refinement, separated by a plus sign. The code is composed of digits and uppercase letters, designed to be readable by people and usable by machines. Short codes may be used by omitting the district portion when the location is referenced within a known city or region; the city or region must be provided to resolve the shortened code. Tools exist to encode coordinates into Plus Codes and to decode codes back into geographic coordinates.

Usage and availability: Plus Codes are integrated into Google Maps and are available via open-source libraries and APIs in multiple programming languages. They enable easy sharing of locations without relying on a formal address, and they can be used offline with appropriate software. They have been employed in humanitarian and disaster-response contexts to rapidly locate places where conventional addresses are unavailable.

History: Open Location Code was released in the mid-2010s as an open standard and is maintained by Google and the Open Location Code community. It remains a widely used, accessible alternative for location reference worldwide.
