[asterisk-biz] Wireless lookup service

[Al Lougher]

Thanks for the info. For some reason I thought Paul had shut his business down sometime ago otherwise that would have been my first stop. I do know he had the data previously because I bought some data over a year ago. I seem to remember the carrier information was not 100% accurate, however determining the carrier is not a priority, as long as it tells me it's wireless that's all that matters. It is my understanding carriers purchase blocks of numbers so really even if NPANXX lookup gives me the answer then that's all I need.

Thanks.
Alan

So 
this is a loaded question...
 
The 
short, yet inaccurate, answer is that I use http://telcodata.us/
 
The 
longwinded answer goes like this:
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. 

 
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 getting 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.
 
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.

        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.
        
Does anyone know of such a service?
        
Thanks
Alan
