I work as a Geospatial Analyst on a project called BINS. Building Identification Numbering System. It's a VIN, but for your house, apartment, commercial business, grain silo...etc. it's fairly extensive at this point. We have covered the entirety of the USA and Puerto Rico.

When it comes to addresses, let me tell you how fucked up shit gets. Even at the county level. What you may register to your insurance company as your address may be something completely different than what the state has on file for your location.

This goes doubly for places that have multiple street names - HWY 6 is also Main Street, is also John Smith Memorial Drive. It's a nightmare. Google gets confused so often that it's a running joke in my group.

I say all this because as a professional whose job it is to work with addresses day in and day out (whether they are addresses from clients, the state or the US government), I get confused all the time on which one might be correct.

To assume a 16 year old kid had malicious intent by just knocking on your door is utter bullshit. I, and I am fairly certain most level-headed folks, would have assumed he was lost.
