It is in fact Discover Student Loans.

They call numerous times everyday.  Told them not interested in student loan,  but they said they will not stop calling until I verify my social number and other information with them (?). I told them my number is on do not call list.  They said they will find other numbers to contact me (...).

wow.. is it just solicitation, and not deliquency bc they are calling me too

The area code is from Utah. I live nowhere near Utah. My philosophy with unknown numbers is if they really need to speak to me they'll leave a message, so far no messages from this number.
