I believe it is Fraud-Because the Gov site says "You get an unsolicited call from someone claiming to work for SSA. Except in rare circumstances, you will not get a call from Social Security unless you have already been in contact with the agency.
The caller asks for your Social Security number — again, something an actual SSA employee wouldn’t do.
A call or email threatens consequences, such as arrest, loss of benefits or suspension of your Social Security number, if you do not provide a payment or personal information.
