It is not. Your SSN cannot be "suspended." This is one of the most common phone scams out there.
Only use official government websites and phone numbers that you find yourself. The SSA's real number is 1-800-772-1213. You can also report the scam to the FTC at reportfraud.ftc.gov. Never trust a number that a caller gave you.
Both are fake. The SSA does not call people to suspend numbers, and they definitely do not threaten arrest over the phone.
