This is a most excellent place for technology news and articles.
The author suggests it was added through people answering the "is this a business" prompts on their phones, not the identity verification.
So, all you have to do to "out" anyone who ever talks to you on the phone is mis-inform Google that the number is a business and "boom" they're out there.
Makes one want to start using callerID spoofing as a regular practice. I am calling from 212-555-1212.
