Adding to my own comment: one thing I forgot about is Google Maps, which reached "basic utility" status in some countries. If your address is wrong on Google Maps, you will have problems, because people will be unable to find your place.

Google provides a way to "submit corrections", but there is no accountability, and these corrections might or might not get applied. In my case, they are sometimes applied: some phones will show the right location, and some will show the wrong one. Again, no accountability.
