[asterisk-users] Mobile Number to Mobile carrier mapping
Hi Folks, Is there a way to find out the mobile/landline carrier name based on the phone number? For example, who is the mobile carrier for (415)2345678 I had heard about some query but just don't remember how/what? Thanks in advance.

Not now that they have intoduced number portability.
The phone companies have to keep huge databases to keep track of which carrier
to send the call to.

Hi Folks,
Is there a way to find out the mobile/landline carrier name based on the phone
number?
For example, who is the mobile carrier for (415)2345678
I had heard about some query but just don't remember how/what?
Thanks in advance.
Ritesh

On Wed, 9 May 2007, Ritesh Agrawal said something to this effect:> Is there a way to find out the mobile/landline carrier name based on the > phone number?Ordinary people can only find this out if the NPA-NXX (area code + exchange, i.e. the first six digits) block to which the number belongs is assigned or delegated to a particular mobile carrier. So, what you'd really be looking up is a particular NPA-NXX block's registered ownership. There are many ways to get this information. You can go to localcallingguide.com and do an "Area Code/Prefix/OCN" search. There's also telcodata.us, and I imagine some others. Or you can download the NXX block assignment spreadsheet straight from NANPA's web site. This type of CO information is public and relatively ubiquitous, if you know where to look. One caveat is that this information can be somewhat out of date or inaccurate, especially in 10000-blocks that have subdelegations across carriers. The other is that this will not properly identify a phone number's origin for you if it's been ported away from the block-owning carrier under the Local Number Portability regime, to someone else in the LATA. This trend has become especially accelerated with the advent of VoIP, when there is additional incentive to get your service from another LEC because it's not just purely a matter of someone's POTS vs. someone else's POTS (or ISDN or whatever). To really know what OCN (Operating Carrier Number) a number is assigned for sure, you have to make a query against Neustar's NPAC database, which SS7 STPs use to do LNP dips. Most mere mortals do not have that ability readily at their disposal, as for the most part any kind of visibility into NPAC is contingent upon being a carrier and operating a switch. Some service providers that are not carriers may have it as well, and I don't really know what Neustar's guidelines for that are. Based on localcallingguide.com, the number you provided is a CommPartners number, as per: http://www.localcallingguide.com/lca_prefix.php?npa=415&nxx=234&x=&ocn=®ion=&lata=&switch=&pastdays=0&nextdays=0 An LNP dip confirms that this number is in fact part of CommPartners, but shows it is not in that original OCN. It is under OCN 533C, which is also CommPartners, but possibly a slightly different trunking handoff, or whatever the logistical difference is. Hope that helps, -- Alex -- Alex Balashov <sasha@presidium.org>
