According to the Medicare website, “All people with Medicare are getting new Medicare cards. These new cards have a new Medicare Number that’s unique to each person with Medicare, instead of their Social Security Number.”
“Medicare has started mailing cards to certain states and will continue mailing nationwide. Your new card will automatically come to you. You don’t need to do anything as long as your address is up to date. If you need to update your address, visit your mySocial Security account.”
