the phonenum module is pretty decent for helping with
NANP numbers and
deciphering if one is let’s say US vs Canada vs Jamaica, etc.
Absolutely. And if his use case is to actually get the political country,
it's a great choice. With that said, I'm guessing that in his case the
vendor wants the + removed for all NANP numbers, so my point was to only
use libphonenumber for this if was critical to differentiate the USA
from the rest of the NANP.

Does it start with a 0?
No. I've never encountered any US number requiring a prefix of
"0"
nor a US number being written that way.
US numbers are fixed lenght 11 digits?
The USA is in the North American Numbering Plan (NANP). This
includes USA, Canada, much of the Caribbean (Cuba, Jamaica, Barbados
for example), some US territories in the Pacific (Guam, American
Samoa). The NANP's "Country Code" is 1. In the USA and Canada (I
think the entirety of the NANP) this is followed with a 3 digit area code (National
Destination Number) followed by a 7 digit subscriber number.
What is the usual representation of a
'local' US number?
There is no consistent answer. Consider that the oldest phone
network is in the USA, and the unplanned initial growth and many
historic regional governing bodies it varies massively. It has also
changed greatly over time. GENERALLY speaking people will use the 11
digit number or the 10 digit number (without the "1" country code), but
there's not a lot of rhyme or reason as to which is preferred in one case vs
another.
