You get your Medicare card automatically when you turn 65, or you can request one if you already have Medicare

Your Medicare card arrives in the mail without you having to do anything — if you are already receiving Social Security or Railroad Retirement Board benefits when you turn 65, Medicare enrollment happens automatically. If you are not yet collecting those benefits, you will need to sign up for Medicare yourself during your initial enrollment window, which is the three months before the month you turn 65, the month you turn 65, and the three months after. Once you are enrolled, your card is mailed to the address on file with Social Security.

If your card is lost, stolen, or damaged, you can request a replacement without waiting. The process is fast — you can order online, by phone, or by mail, and a new card typically arrives within 5 to 10 business days.

Key Takeaways

  • If you receive Social Security or Railroad Retirement Board benefits, Medicare enrollment and your card happen automatically at 65 — you do not need to do anything.
  • If you do not receive those benefits, you must sign up for Medicare yourself during your initial enrollment window: three months before, the month of, and three months after your 65th birthday.
  • You can request a replacement card online through your Medicare account, by calling 1-800-MEDICARE, or by mail to Social Security.
  • Your new card will show your Medicare number, which is now your Social Security number followed by a letter suffix, rather than a separate claim number.

When your card arrives automatically

Social Security and the Railroad Retirement Board coordinate with Medicare, so if you are already collecting benefits from either one, your Medicare enrollment is handled without a separate step. Your card is mailed to the address Social Security has on record for you. This happens about two weeks before your 65th birthday, so you should receive it shortly after you turn 65.

Check the address on your Social Security account now. If you have moved recently or the address is wrong, update it with Social Security before your 65th birthday. You can do this online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. Updating your address with Social Security automatically updates it with Medicare.

If you are not yet receiving Social Security benefits

You must sign up for Medicare yourself if you are still working at 65 or have delayed claiming Social Security. Your enrollment window is seven months long: the three months before the month you turn 65, the month you turn 65 itself, and the three months after. If you miss this window and do not have a may have access to reason for a late sign-up, you may face a permanent penalty on your premiums.

To sign up, go to Medicare.gov, call 1-800-MEDICARE, or visit your local Social Security office. You will need your Social Security number and proof of citizenship or legal residency. Once you enroll, your card will be mailed to the address you provide. If you are still working and have health insurance through your employer, tell Medicare when you sign up — this affects which parts of Medicare you need to enroll in now versus later.

How to request a replacement card

If your card is lost, stolen, or damaged, you have three ways to get a new one. The fastest method is online: log into your Medicare account at Medicare.gov, go to "Manage Your Health Information," and select "Order a Replacement Medicare Card." You will be asked to verify your identity and confirm your mailing address. A new card is mailed within 5 to 10 business days.

You can also call 1-800-MEDICARE and speak to a representative who will verify your identity and mail a replacement. This takes slightly longer because the representative must process your request manually, but it is still faster than the mail option. If you prefer to request by mail, send a letter to Social Security with your name, date of birth, Social Security number, and current address. Include a note saying you need a replacement Medicare card. Mail it to the Social Security office in your state — you can find the address at ssa.gov.

Understanding your new Medicare card format

Medicare cards issued after April 2018 show your Social Security number followed by a letter suffix (usually A, B, or D) rather than a separate Medicare claim number. This change was made to protect privacy. Your card also displays your coverage effective date and which parts of Medicare you are enrolled in — Part A (hospital insurance), Part B (medical insurance), or both.

Keep your card in a safe place. You will need the number when you see a doctor, fill a prescription, or contact Medicare. You do not need to carry the physical card with you — most providers can look up your information using your Social Security number and date of birth. However, it is useful to have the number memorized or written down for reference.

What to do if your card does not arrive

If you turned 65 and enrolled in Medicare but your card has not arrived after four weeks, contact Social Security to confirm your address is correct. Call 1-800-772-1213 or visit your local Social Security office. They can verify that your card was mailed and provide your Medicare number over the phone so you can use it when ready with your doctor or pharmacy.

If your address changed after you enrolled but before your card arrived, you can update it with Social Security and request that your card be re-mailed. This takes an additional 5 to 10 business days. In the meantime, you can use your Social Security number and date of birth to prove you have Medicare coverage.

Frequently Asked Questions

Do I need to do anything to get my Medicare card when I turn 65?

Only if you are not yet receiving Social Security or Railroad Retirement Board benefits. If you are already collecting from either program, your card is mailed automatically. If you are not, you must sign up for Medicare during your enrollment window (three months before, the month of, and three months after your 65th birthday) by going to Medicare.gov, calling 1-800-MEDICARE, or visiting a Social Security office.

Can I get my Medicare card before I turn 65?

No. You become may be able to access for Medicare the month you turn 65. Your card is mailed during the month you turn 65 or shortly after, depending on when Social Security processes your enrollment. If you need your Medicare number before the card arrives, you can call 1-800-MEDICARE and a representative will provide it.

What if I am still working at 65 and have employer health insurance?

You still need to sign up for Medicare, but the timing matters. If your employer has 20 or more employees, you can delay enrolling in Part B without penalty. However, you should still enroll in Part A (hospital insurance) at 65. Contact Medicare or your employer's benefits department to understand your specific situation before your enrollment window closes.

How long does it take to get a replacement card?

If you order online through Medicare.gov, your new card arrives within 5 to 10 business days. Calling 1-800-MEDICARE takes about the same time. Requesting by mail to Social Security may take 2 to 3 weeks. In all cases, you can use your Social Security number and date of birth to prove coverage while you wait.

What should I do if my card arrives with the wrong information?

Contact Social Security when ready at 1-800-772-1213 or visit your local office. Bring your card and proof of the correct information (such as a birth certificate if your name is wrong, or a utility bill if your address is wrong). Social Security will correct the error and mail you a corrected card within 5 to 10 business days.
