When will I get my card?

Once you sign up for Medicare, Social Security will mail you a Medicare card that looks like this:

Your Medicare number is usually the same as or very similar to your Social Security number. Be sure to keep your card and number safe. Do not share them with anyone except your medical providers.

If you sign up for Part C (Medicare Advantage), Part D (prescription drug) or a Medigap plan, or have Medicaid, these plans will mail you a separate membership card. Keep these cards safe and bring them with your Medicare card to the medical provider or the pharmacy. You will need to let your providers know which plans you have.

NOTE:  The sample Medicare card pictured above is the new Medicare card.  A new federal law requires Medicare to remove all Social Security Numbers (SSNs) from all Medicare ID cards by December 2019. Between April 2018 and April 2019, Medicare is mailing out new Medicare cards to beneficiaries. The new cards will have a new Medicare number that's unique to you, instead of your SSN. This will help protect your identity.

If you lose your Medicare card, you can ask for a new one from Social Security:

Social Security will mail you a new card in about 30 days. If you need proof before your card arrives, ask Social Security to provide you with proof you can use until you get your replacement card.

How do I change my name or address for my Medicare card?

Medicare uses the name and address you have on file with Social Security. To change your name and/or address, go to your my Social Security account (www.ssa.gov).
