You're right. Since the postal worker knows his route, he knows my name. So snail mail works perfectly well. Same for the Amazon delivery person (took a few visits). Same for the local pizza place.

It's online address suggestion/validation/one-time deliveries that don't work well. E.g. Uber Eats and DHL drivers always require a phone call so that I can guide them along the final hundred meters of their delivery. I usually go downstairs and meet them at the curb.
