I got an email from lawyers of one of the many class action lawsuits running around these days regarding providing proof of ownership of my phone number. I thought it would be an easy matter to print out one of my Sonic bills, but when I looked at the invoice, my phone number, which is managed by Sonic, doesn't appear anywhere on the invoice. This seems a bit weird to me. There is some "pair" info, but I don't think that will do to show that I own this phone number.
Can someone shed some light on this?
