A lot of countries in Africa do not have addressing systems and there is a push to have them adopt these granular forms of addressing for e-commerce and government service delivery. But existing addressing systems are structured to precisely link occupants to specific identity. I am reading more on this and would appreciate any leads.
I did not know of Plus Codes but I do know of GhanaPostGPS. I see how this can be worked on to offer a better addressing system without taking too much information away from the individual. Something like a GPS location that is hashed. Then time-sensitive address tokens can be used depending on use case. If you buy a product and should be delivered in three days, you can give a token with one week expiration. That way, the company cannot use your purchase details to link to your address since the token has not real GPS location on it. But there are many loopholes that can be exploited in many ways.
But you can’t expire a physical location. So once that store converts it into a location there is nothing stopping them from storing that, even if the original token expires.
The conversion part is the tricky bit. If a third party decides to use their own system to convert GPS location to deliveries, that is out of your control. But you can perhaps use delivery locations that do not necessarily point to your exact location. It is a hard problem to both have a fixed location address and still keep some privacy.
