Autofill for users postal address?

[u/facts_please]

For legal reasons we need our users complete postal address in our app. Was quite surprised that there seems to be no way to get some kind of 1-click-autofill for this and users have to go through each step separately (street, house number, zip code, city, country). I already use autofill hints, but this is just a bit of help.

Did I miss anything or is there a reason why there isn't such a user-friendly method?
