Doesnt Medicare need to know my Social Security number?
Yes, Medicare does need to know your Social Security number in order to provide you the benefits to which you are entitled. However, like many other companies, Medicare can discontinue the use of Social Security numbers in public places, like ID cards and mail. They can use a randomly generated ID number that would appear on public documents but that would connect you to your Social Security number. Thieves would not be able to use this number to open credit card accounts or steal money from existing accounts.
