This is a scam masquerading as coming from the "DO NOT CALL" list. No area code is displayed. They ask you to enter "1" to be placed on the list, then ask you to enter your full 10-digit number. It is no doubt a phone version of a "phishing scam", which begs the question: Why don't they just open the phone book? The National Do Not Call Registry does NOT make calls to anybody!
This call is computer-generated (SMS) and is probably a "Magic Jack" number (which cannot be traced to anybody).
