Re: CNAM/LIDB questions

said by royrogers:

(1) Who are the big CNAM database providers?

(2) Is there a way to check these databases without having to subscribe? Like a central clearinghouse that will tell me what everyone has on file per a certain #. I doubt it, but I thought I'd ask.

(3) Does anyone know where Callcentric gets their CNAM data?

1. Targus and Verisign, I believe. But Targus is now owned by Neustar, and Neustar is run by the woman who destroyed SunRocket.

2. No.

3. Proprietary.

Thanks. Doing a little research using Neustar and VeriSign, looks like TNS is another fairly large provider.

TNS took over the CNAM part of Verisign, fyi.

No problem.

I can also tell you that Level 3 hired TNS to host their LIDB & CNAM database. This makes TNS the authoritative source of Level 3 data.

But I thought they're now Neustar, no?

I have a client with a phone # that, when they call me, the CNAM I get from Callcentric is for a business that probably previously had that #.

So I went to your "North American number lookup" and punched the # in, and sure enough, the CNAM matches what I'm getting from Callcentric.

So I do a little research and find that Targus is now Neustar? So I found this site (part of Neustar):

»webapp.localeze.com/directory/search.aspx

And I punch-in the phone #, but they don't have any listing for the #.

How is that happening?

I assume I must be wrong and Targus did not become Neustar?

That is helpful to know, because the #'s that tend to be a problem are L3 #'s.

Neustar is a big company.

Many databases, many offices and people.
