You can order a replacement Medicare card online, by phone, or by mail — the online method is fastest and requires no documents

If your Medicare card is lost, stolen, or damaged, you can get a replacement without visiting an office or waiting weeks. Medicare sends replacement cards to your home address on file, and the process takes about 7 to 10 business days once your request goes through. You do not need to prove the card was lost or damaged — Medicare will issue a new one based on your Social Security number and identity information.

The fastest route is the official Medicare website at Medicare.gov. You can also call Medicare directly at 1-800-MEDICARE (1-800-633-4227), or request one by mail if you prefer not to use the phone or internet. Each method works, but online is quickest because there is no wait time to speak with someone.

Key Takeaways

  • Order your replacement card online at Medicare.gov/myMedicare, by calling 1-800-MEDICARE, or by mailing a form to your local Social Security office.
  • You will need your Social Security number, date of birth, and the address where you want the card mailed — no documents required.
  • Replacement cards arrive in 7 to 10 business days; if you need coverage information before then, you can view your Medicare details online or call for a temporary reference number.
  • Your old card stops working once the new one is issued, so do not use it after your replacement arrives.
  • If your card was stolen, you can report it to Medicare, though this step is optional and does not speed up the replacement process.

Ordering online through your Medicare account

The online method is the simplest if you have internet access and a Medicare.gov account. Go to Medicare.gov/myMedicare and sign in with your username and password. If you do not have an account yet, you can create one using your Social Security number, email address, and a password you choose.

Once you are signed in, look for the option to order a replacement card — it is usually listed under "Personal Information" or "Medicare Card." Click through to confirm your mailing address, then submit your request. You will see a confirmation message on screen, and Medicare will send you an email confirmation as well. Your new card will arrive at the address you provided within 7 to 10 business days.

If you run into trouble signing in or navigating the website, you can call 1-800-MEDICARE and ask for help creating an account or submitting your request. The phone line is open Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday, 9 a.m. to 1 p.m. Eastern time.

Ordering by phone

Call 1-800-MEDICARE (1-800-633-4227) and tell the representative you need a replacement card. Have your Social Security number and date of birth ready. The representative will confirm the address where you want the card mailed and ask whether the original card was lost, stolen, or damaged — this is just for their records and does not change the process.

The call usually takes 5 to 10 minutes. You will receive a confirmation number, which you can write down or ask the representative to email to you. Your replacement card will arrive within 7 to 10 business days. If you are calling from outside the United States, use the international phone number provided on the Medicare website.

Ordering by mail

If you prefer not to use the phone or internet, you can request a replacement card by mail. read the form "process for a Social Security Card" (Form SS-5) from the Social Security Administration website, or pick one up at your local Social Security office. Fill out the form with your name, Social Security number, date of birth, and the address where you want your Medicare card mailed.

Mail the completed form to your local Social Security office. You can find the address on the Social Security Administration website by entering your zip code. This method takes longer than phone or online — typically 2 to 3 weeks for the form to reach the office, plus another 7 to 10 days for the card to arrive at your home.

What to do while you wait for your replacement card

You do not need your physical card to receive Medicare services while you wait for the replacement. Doctors and hospitals can look up your Medicare information using your Social Security number and date of birth. If a provider asks for your card number, you can give them your Social Security number instead, or call Medicare at 1-800-MEDICARE to get a temporary reference number you can provide over the phone.

You can also view your Medicare information online at Medicare.gov/myMedicare, which shows your coverage details, claims, and prescription drug information. Print or screenshot this page if you need proof of coverage for an appointment.

If your card was stolen

Reporting a stolen card to Medicare is optional but recommended if you are concerned about identity theft. Call 1-800-MEDICARE and tell the representative your card was stolen. They will flag your account and can help you monitor for suspicious activity. You can also report the theft to the Social Security Administration at 1-800-772-1213.

If you notice charges or claims on your Medicare account that you did not authorize, contact Medicare when ready. You can dispute fraudulent claims online through your Medicare.gov account or by calling 1-800-MEDICARE. Keep records of any suspicious activity and report it to the Federal Trade Commission at IdentityTheft.gov if you believe your identity has been compromised.

Tracking your replacement card

Medicare does not provide tracking numbers for replacement cards, so you cannot check the status online. However, if more than 10 business days have passed and your card has not arrived, call 1-800-MEDICARE to confirm that your request was processed. Have your confirmation number ready if you received one.

If your address recently changed, make sure Medicare has your current mailing address on file before you request a replacement. You can update your address online through Medicare.gov/myMedicare or by calling 1-800-MEDICARE. If your card is sent to an old address, you will need to submit a new request with your updated address.
