Mobile phones in the US & Canada do not fall into a few special area codes
as they do in most of the rest of the world, rather mobile phone numbers are
allocated in blocks of 10000 on the basis of three digit exchanges or
"Central Office Codes" (AAA-NNN-XXXX). So, there are thousands of possible
six-digit prefixes needed to capture all mobile phone numbers. The best
resource to figure out which company "owns" which Central Office codes is to
look on www.nanpa.com, but you'll be in for a lot of work if you want to
sort it all out.

And even if you do, thanks to number portability, it won't even be
consistently accurate.

There are no mobile phone prefexes in Canada and USA.
They are same as land lines. ie area code plus phone number.
If I gave you a mobile number you would not be able to distinguish it
from a land line unless you researched who controls the number. There
are websites that will tell you but not provide you with a list. As it
was mentioned with number portability it is possible to take a land
line number and switch it to a mobile phone and vice versa. This is
very useful for small businesses who want to create an image of a
larger company without maintaining a land line.

Sure there are, it's just based on NPA-NXX (and sometimes even another
-X)

However, from a billing and routing point of view they're exactly the
same. Also, like my previous post mentioned, with number portability in
place the assignments aren't totally reliable anyway.

Nope, no downloadable information available in Canada...

In the US it's a bit more difficult to get a complete list, but you can
still pull lists of entire state/NPA combinations easily.

The page is scrapeable too...
