Do not call this number. This is a SCAM! They send you a very, very realistic insurance document saying you are due a check, or that one is being held for you. On the document they want your last 4 SSN, a signature, and a PIN. Also do not call that number and enter that information. With this information they can steal your identity. The address to send it to is bogus for the insurance company they are purporting to be. That address is p.o. box 5370, Scranton, PA 18505-5370. This is one of the best phishing attempts I've ever seen. The FEDS need to get on this quick and find out who is renting this p.o. box or who the phone number is registered to! Never respond to an "official" [but fake] document without performing some due diligence as to why you are receiving it and asking for your identity details. Be safe.
