So I noticed that many Bitcoin sites utilize 2 Factor Verification for new registrations. This requires you to provide your cell # and they send you a code which you type in to verify.

I'm always hesitant to provide my cell # because I want to maintain my anonymity as much as possible. Does anyone know if the phone # data is stored for 2 Factor Verification? Of course I know it is for 2 Factor Authentication but I'm specifically referring to 'Verification".

Giving numbers isn't really a big deal, at least for me. I even like the only phone number required than other ways of doing verifications.

At some sites, after you gave the phone number, you must passed another level of verification which is way more private.

And if the site you are referring is quite reputable, why worries too much. Yes numbers can be traced but I doubt someone will put an effort to traced thousands of numbers just for their sh*t intention.
