This a phone number provided in a letter for unsolicited insurance products. The letter includes NO name or address of the sender; neither is there a return address. The only way to establish who it is from is to call the number. It does say that it is a solicitation of insurance from a "third party partner." The letter has in bold letters, "Medicare Notice" seemly to make an unsuspecting person believe it is from the governmental Medicare agency. I believe any reputable company would provide a name and address to a prospective client. This Search Engine had no information for this number.
