> By convention in Utah, the first tuple element is the house number and the second element is the street.

So I learned something about this when I bought my house. If the second element is a named street, then you're expected to omit the cardinal direction from the first element. So, taking the address in the OP as an example, if 630 S was a street named Foo Boulevard, then the address is correctly written (from USPS' POV) as either 716 Foo Boulevard or 716 W 630 S. Before learning that, I would certainly have written 716 W Foo Boulevard and, indeed, that's what many if not most Utahans expect. (And, actually, including the cardinal direction disambiguates some cases, e.g., State Street. There's a donut shop (best glazed donuts in the valley) at 2699 State Street and the Capitol Building is at 350 State Street. Except the first is S and the second is N, so they're 3049 units away, not 2349.)

Anyway, it's kinda interesting to me because, if I use the former notation of specifying my home address, some navigation systems will put people a couple miles away at some church but it always (so far) works if I use the latter notation. It most recently confused the navigation system a local towing company uses until I gave them the address in the latter notation.
