Street name and number is also not required for delivery of
mail. When Canada introduced the postal code, many journalists
attempted to send letters addressed like this:

Fred Bloggs
N2L 4H2

And they were all delivered promptly with no discernable delay.
Judging by the USPS description of their ZIP+4(tm) codes, you
should get similar results with:

Sarah Bloggs
95121-1520

I agree. There is value in knowing the geographic distribution
of address usage, especially if we want to adopt a geo-topological
addressing scheme for IPv6 at some future date.
