Look for your new Medicare cards in the mail; unique Medicare number

Missouri residents will start receiving their new Medicare cards. Be looking for yours in the mail. Remember, you don’t have to do anything. The new cards will automatically be mailed to the address Social Security has on file for you.
The cards will have a new unique Medicare Number instead of a Social Security number.
After you receive your new card, Medicare advises you to destroy your old card, start using your new card right away, and beware of scammers trying to get your new number.
