Google Maps Plus Codes are an innovative geocoding system developed by Google to simplify address location, offering a user-friendly alternative to traditional geographic coordinates like latitude and longitude. This system allows, for example, the identification of different entrances to the same building using a simple grid and a carefully selected 20-character alphanumeric code, chosen to avoid confusion by excluding characters such as “1” or “l”. A concrete example of a Plus Code would be the Victor Hugo metro station in Lyon, identified by the code QR3H+5M Lyon. This simplified location system is a major advantage for Google Maps users.
