@chrismessina @nikkielizdemere Hi Chris, while we do utilize public records sometimes in our EveryoneAPI product, it is not a primary source for OpenCNAM. OpenCNAM uses carrier (phone company) supplied data first, and if our Plus service level is enabled, several dozen sources are utilized until a result is found. If you shoot me an email at chris.brunner@telo.com, I'd be happy to get on the phone and discuss this in more detail with you.

@chrisbrunner thanks. I was just curious. Have you inked deals with the carriers individually or do they offer open APIs? I'm just curious how you're able to get this information, how accurate it is, and what control the phone number owners have over the release of their information.

@chrismessina Chris, we acquire all of our data through contractual relationships. Before we came about, there was no open API for retrieving this information, which is precisely why we built OpenCNAM. The data is extremely accurate, since it comes from telephone companies, and consumers have full control over whether or not their information is displayed. Some carriers offer a toggle in their customer portal and for the others, a quick phone call to 611 can be made to have your outbound Caller ID enabled or disabled.

Today there's over 70 SMS APIs. I imagine there will be a similar number of these types of caller ID APIs soon. ;) Looking forward to commoditization/cheaper versions of this. WHen I call support, they'll know exactly who I am.
