To protect your identity, starting in April 2018, Medicare will mail new Medicare cards without Social Security numbers printed on them. There's nothing you need to do! You'll receive your new card at no cost at the address you have on file with Social Security. If you need to update your mailing address, log in to your my Social Security account. For more information about the new Medicare card, visit https:/go.medicare.gov/newcard.

Also please note:

• Mailing takes time. Your card may arrive at a different time than your friend’s or neighbor’s.
• Your new card is paper, which is easier for many providers to use and copy.
• Once you get your new Medicare card, destroy your old Medicare card and start using your new card right away.
• Doctors, other health care providers and facilities know it’s coming and will ask for your new Medicare card when you need care, so carry it with you.
• Only give your new Medicare Number to doctors, pharmacists, other health care providers, your insurers, or people you trust to work with Medicare on your behalf. 

Medicare will never call you uninvited and ask you to give us personal or private information to get your new Medicare Number and card.
