The new standard under NG9-1-1 is GIS with a standard data model. All of
that is documented by NENA:
https://cdn.ymaws.com/www.nena.org/resource/resmgr/standards/nena-sta-006.2a_ng9-1-1_gis_.pdf.
Emergency Call Routing Function (ECRF) uses this data to locate the
correct PSAP to route a call to.
Some states have their own additions to the NENA standards that aim to
add consistency to the fields themselves (eg. Post Directional address).
There also exists a standard
(https://cdn.ymaws.com/www.nena.org/resource/resmgr/Standards/NENA_71-501_GIS_MSAG_ALI_05-.pdf)
for converting from GIS to MSAG for hand off to non-NG9-1-1
applications. It specifies the conversion from PIDF-LO into a MSAG
record (and the opposite way if needed).

911 is based on MSAG (Master Street Address Guide), not USPS. However,
many operators are likely using the USPS system to sanitize the inputs.

Your schema is probably good for 99% of the population. I do wonder
though if USPS is the right / sole agency to maintain. Having 911
dependent on an incomplete database seems unwise. Or is it ALI? Not
sure if it was Verizon's front end or back end that was the real
problem there.
The first time I encountered the problems of living in a place with no
postal delivery I had a related challenge which was to obtain a new
driver's license (along with updating vehicle registration and voter
registration). New Mexico requires two proofs of current residential
address which for good reasons cannot be a PO Box. The house I was
renting was fairly new and I don't think USPS knew it even existed.
There were no road signs or house numbers posted. The first time that
I visited it the landlord rode along and gave me turn-by-turn
directions. There was an address on the lease I signed, but I had no
way to verify it corresponded to the property I visited. In fact later
I learned that the lease was copied from a template and the address
had not been updated (when even property owner gets it wrong, what
hope does a bureaucrat have?)
It took multiple trips to the MVD to obtain a license, being turned
away several times for insufficient paperwork. I had no utility bills
for an off-grid home with no postal delivery. In the end they accepted
a copy of the lease (which I had to photoshop to show the correct
address) and a statement from the bank. But wait... where did the bank
get my address? I gave it to them verbally and they accepted it as
fact. Some time after getting my ID I found a document issued by the
county that assigned a street address to the house for emergency/law
enforcement purposes. To my knowledge that is the one and only
official documentation of the address.
It was around this time (2012) I first became aware of an impending
REAL ID requirement that the state was rushing to meet. The paradox of
having to manipulate the system to prove my actual residence to obtain
a more secure & state-mandated ID card was not lost on me. I never did
try to update 911 location when I lived there.
This situation of USPS vs 911 vs DMV vs. bank vs. insurer vs. county
assessor/elections vs. ? reminds me a little of "Gay marriage: the
database engineering perspective" (
https://web.archive.org/web/20170118114056/https://qntm.org/gay ) and
if I were tasked with creating a grand unified address database all
those entities could use I'd be studying it and probably also Wes
Kussmal's "The Sex Life of Tables: What happens when databases about
you MATE?"
Can I have two entries for two residences? How/who decides which is
"primary" for income tax purposes then? Can I have zero entries for
being unhoused but have a cell phone and potentially need 911
services? If I'm paranoid can I opt-out of that for mental health
reasons? Can I delete an entry my parents added after I'm disowned,
preferably without setting up a forwarding entry?
I guess the current state of REAL ID should quash any hopes I have for
resolving even the relatively simpler problem of 911 USPS location
dependency.
