We have an ongoing address issue which just got bigger. Our house and street number are the same as another home in our HOA, only they are “road” while ours is “street”. We get lots of their mail, including one letter that was redelivered to us 7 times.
Similar thing at our last house. The local mail carrier was worthless, and UPS and FedEx weren't much better, so we both got in the habit of just going to the other's house and dropping off mail and packages. After a couple of years we got to be good friends!
Hard to believe the local planning agency couldn't do a better job of monitoring street names when they're being built.
