short, yet inaccurate, answer is that I use <A

<DIV><SPAN class=750025200-31072008><FONT face=Arial color=#0000ff size=2>The
longwinded answer goes like this:</FONT></SPAN></DIV>
<DIV><SPAN class=750025200-31072008><FONT face=Arial color=#0000ff size=2>With
the advent of Number Portability (both Local Number Portability and Wireless
Number Portability), that data changes on a day-to-day basis as users swap from
provider to provider, and other reasons numbers might shift from one carrier to
another. The only true maintainer of which provider serves a particular
number is NANPA (which contracts Neustar to handle this), which is who the
carriers report their changes and ports to. Even the major
carriers get daily updates to this data, or they query Neustar themselves.

<DIV><SPAN class=750025200-31072008><FONT face=Arial color=#0000ff size=2>There
are a number of somewhat expensive methods to access this data (I say
expensive to mean it's cost prohibitive for many small businesses). Most
revolve around g</FONT></SPAN><SPAN class=750025200-31072008><FONT
face=Arial color=#0000ff size=2>etting SS7 access (equipment and service) or
getting an account with Neustar directly (which often requires you to be a
carrier yourself). You can pay a number of companies like Verisign or NetNumber
per query (which, just get their data from Neustar). You might be able to locate
a provider who will offer to provide queries for you, say, through HTTP, but I'm
reasonably certain (if I remember correctly from my Neustar legal documentation)
that they expressly forbid this, and require that the data just be used for
routing.</FONT></SPAN></DIV>

<DIV><SPAN class=750025200-31072008><FONT face=Arial color=#0000ff size=2>So,
your best bet might be to use a database like I've mentioned above with a "best
guess" approach. All my research leads me to believe you'll get somewhere around
95% accuracy, though perhaps more for wireless because people tend not to port
wireless numbers as frequently.</FONT></SPAN></DIV>

<P>I'm looking for a service that can provide either a database or
method for looking up a number to determine if it is wireless
or not. Doesn't have to give carrier information (although that would be
nice). US only.</P>
<P><BR>Does anyone know of such a service?</P>
