Your Medicare card arrives about two weeks before your 65th birthday
Medicare automatically sends your card to the address on file with Social Security about two weeks before you turn 65. You do not need to do anything to receive it — the enrollment happens on your own once you reach 65, as long as you are a U.S. citizen or permanent resident who has lived in the country for at least five years.
If your birthday falls on the first of the month, your coverage starts the first day of the previous month. If your birthday is any other day, coverage begins the first day of the month in which you turn 65. This timing matters because it determines when your card arrives and when you can start using your benefits.
The card itself is a physical piece of plastic with your name, Medicare number, and the type of coverage you have. Keep it in a safe place — you will need to show it to doctors, hospitals, and pharmacies. If your card does not arrive within three weeks of your birthday, or if it arrives damaged, you can request a replacement through your Social Security account online or by calling Social Security directly.

- Check your Social Security address now to make sure your card will be mailed to the correct location.
What to do if your address has changed
If you have moved since your last Social Security update, update your address now — before you turn 65. Your Medicare card will be mailed to whatever address Social Security has on record, so if that information is wrong, your card may go to an old home or get lost.
You can update your address online through your Social Security account at ssa.gov, or you can call Social Security at 1-800-772-1213 (TTY 1-800-325-0778). Have your Social Security number ready. If you update your address online, the change takes effect when ready. If you call, allow a few business days for the update to process.
If you are moving soon but have not yet changed your address, consider updating it as soon as you have a confirmed new address. This gives Social Security time to process the change before your card is printed and mailed.
What happens if your card arrives late
If your 65th birthday passes and your card has not arrived, do not panic — you are still covered by Medicare on your birthday even without the physical card in hand. Your coverage is active in the system, and doctors and hospitals can look up your information using your Social Security number.
Wait until three weeks after your birthday before requesting a replacement. If it still has not arrived by then, you can request a new card through Social Security online at ssa.gov or by calling 1-800-772-1213. When you call, have your Social Security number and date of birth ready. Social Security will mail a replacement card to your current address, which typically arrives within 5 to 10 business days.
In the meantime, if you need to see a doctor or fill a prescription, bring your Social Security number and a photo ID. Most providers can verify your Medicare coverage through the system even if you do not have the card yet.
Understanding your coverage start date
Your Medicare coverage does not start on the day you receive your card — it starts on a specific date determined by your birthday. Knowing this date matters because you cannot use your benefits before that date, and you may face penalties if you delay signing up for certain parts of Medicare.
If you were born on the 1st of any month, your coverage begins on the 1st of the month before your 65th birthday. For example, if you turn 65 on March 1st, your coverage starts February 1st. If you were born on any other day of the month, your coverage begins on the 1st of the month in which you turn 65. For example, if you turn 65 on March 15th, your coverage starts March 1st.
This distinction matters for timing prescriptions, scheduling procedures, and understanding when you can first use your benefits. Mark your coverage start date on your calendar so you know when you can begin using your Medicare benefits.
What your card shows and how to use it
Your Medicare card displays your name, date of birth, Social Security number (or Medicare number), and the type of coverage you have. It also shows the date your coverage began. The card is small and fits in a wallet, but treat it like you would a credit card — keep it safe and do not share your Medicare number with anyone except your doctor, hospital, or pharmacy.
When you visit a doctor, hospital, or pharmacy, show your Medicare card. The provider will scan or record your Medicare number and use it to bill Medicare for your services. If you have prescription drug coverage (Part D), your pharmacy will also use your card to process your prescriptions. If you have a Medicare Advantage plan (Part C), your card will show that plan's name and may have a different number for that plan.
Keep your card with you at all times once you receive it, especially if you travel or have regular medical appointments. If you lose your card, request a replacement when ready so you do not have gaps in your ability to access care.
Preparing before your card arrives
While you wait for your card, gather information about your healthcare providers and medications. Write down the names and phone numbers of your doctors, dentist, and any specialists you see regularly. Make a list of all medications you take, including over-the-counter drugs and supplements, because you will need this information when you enroll in prescription drug coverage.
If you have not already chosen a Medicare plan, start researching your options now. You have choices between Original Medicare (Part A and Part B) and Medicare Advantage plans (Part C), and you will need to decide whether to add prescription drug coverage (Part D). Your plan choice affects which doctors and pharmacies you can use and how much you pay for care.
Review your current health insurance coverage to understand what will change once Medicare starts. If you have coverage through a current or former employer, you may be able to keep it alongside Medicare, but the rules vary. Contact your employer's benefits office or your insurance company to ask how your coverage will work once Medicare begins.
