They're definitely not possible across the country because long
distance calls only do the LNP lookup after routing the call to
the destination tandem. (That's the L in LNP.)
Usually this is because their numbers can't support nomadic 911.
It's more than that, long distance carriers couldn't

Yeah, I guess it makes sense at a technical level. Any CLEC can, in principle,
pick up a call from anywhere in the LATA at the ILEC tandems (notwithstanding
issues of DEOTs and all that), and they do so with regularity.
I just thought there was something in one hundred percent of ICAs that

You need to know where the call is going to go, which cannot be
determined from the number itself[1]. So, you still need to do an LNP

NPAC has a service type field that indicates wireless/wireline. That
doesn't solve for native numbers though since
Nothing as long as companies don't offer both services. Looking up the NPA-NXX
of the LRN in LERG 6 would tell you both what the service is and if the NXX is
portable.

Not at all impossible. It could be not be further from impossible. The

prosecute. Straight talk has a home service that essentially uses a

Carlos,
you can get a list of all NPA-NXXs that are used by cell carrier
and use that as a starting point. Then add to that the list of
LRNs used by call carriers which may or may not be included in the
first list.
Then you need to dip your
