Plus Codes are like street addresses for people or places that don’t have one. Instead of addresses with street names and numbers, Plus Codes are based on latitude and longitude and displayed as numbers and letters. With a Plus Code, people can receive deliveries, access emergency, and social services, or just help other people find them.
I find my location Plus Code with this online tool web page.
For example, you can use the Plus Code address to buy and connect to Starlink.
