That's kind of the point, US Telcos don't really validate customer identity - probably because they can't, due to the general limitations of USA documents leading to relatively easy identity theft where merely having enough information is sufficient to impersonate someone. (A simple test - is your verification process likely to stop someone's parent, spouse or sibling from impersonating them? If no, you're not really verifying identities.) It's not something where a private entity can sell a solution, you need a more solid root of trust for verifying actual identities, like many other countries do, but that's not going to happen in USA any time soon.
