My reading of the article is quite different from yours. The author writes,

> I can only tell you that I live in Kanyanya, a Kampala suburb. If you need my exact home, then I’ll either have to send you a GPS location via apps like Whatsapp, Telegram, Google Maps or engage you in a long phone conversation in which I’ll try to describe landmarks, building and trees leading to my house. But street address, zip code? Hell No.

And says that despite that, the web forms ask for nonsensical data. The right thing is for the delivery location validator to take GPS, phone number, list of landmarks, etc, canonicalize it as best it can, and send that info to the delivery company. Not try to fit the delivery info into some Procrustean form.
