Not native American, but grew up in a rural area (in Canada). My parents only got a "street address" a couple of years ago. There is a land location system going back over a century, but basically no one who didn't live on a farm new how to interpret it (say 98% of the population), and so it was basically useless as an address. The new "street address" is actually based on the land location, but it is formatted like a street address (house number, road name) rather than specifying quarter, section, township, range, meridian. Throughout my childhood, we usually just used a postal address, but in the last couple of decades, bank officials and the like have gotten more and more insistent on a physical address which we were basically unable to provide.

Native American land laws are a disaster, and it’s not their fault. It’s a large contributor to poverty as well. I’m still not sure if that was an unintended or intended consequence of US govt treaties.

Why is this comment so downvoted? I'm not american, and I was also curious about why they don't have an adress.

As far as I know, only homeless people don't have an adress in Denmark.

EDIT: Great, now I'm downvoted as well! Huzzah!

Where I grew up in Montana, we didn't have a street address. Only about 20 years ago did they name the road (after my grandfather) and assign addresses.
