If they're land lines, the NPA/NXX will be local to the CO so you won't
have out-of-area numbers other than a rare corner case of a very
expensive foreign exchange line. If they're VoIP lines, the address is
*supposed* to be so registered, but softphones and even VoIP handsets
tend to move around without the user considering 9-1-1.

VoIP was dragged kicking and screaming into E911, so now they charge
extra and are quite clear about it.  My VoIP provider regularly
reminds me to update my 9-1-1 address, but since I don't have to pay
the 9-1-1 fee if I lie and say I'm outside North America, that's what
I do.  Since I also have a classic CO-powered copper landline (1/4
mile from the CO, no concentrators or repeaters) and a couple of cell
phones, I think we're covered.

With my VOIP provider, I didn’t quite have to lie.

I generally don’t need my VOIP number when I’m in the US (cell is free here),
so I simply told them “I do not intend to use this number or this service
within the US”.

The first time I sent them a marked-up contract, they contacted me with
questions. The following year, the new version of the contract reflected
my changes to their original wording.

Since then, I’ve been pretty much satisfied with my service from callcentric
and the price is right.

Quick question:  What happens (in the purely hypothetical case, I sincerely hope) if the building is on fire and it 
turns out that the VOIP-phone is the only one that works?

That would be an interesting phenomenon since my VOIP clients are both dependent on data services working on one of 
laptop, iPad, iPhone.

Do you leave it turned off?

Of course not, but since the building in question is very unlikely to have been any address I would have filed on said 
contract, it’s far better that the person at the other end is having to ask me for the address than to have emergency 
workers respond to some location that I’m not at.

If, OTOH, the building in question is my home, I’m more likely to get a faster response by banging on a neighbors door 
than by struggling to get the VOIP phone up and running on some alternative connectivity.
