Get a replacement card from Medicare directly — it takes about 7 to 10 business days by mail, or you can print a temporary one online right now

You do not need your physical card to see a doctor or fill a prescription. Medicare uses your Social Security number to identify you in their system, and doctors and pharmacies can look up your coverage using that number alone. But you will want a replacement card for your records, and the process is straightforward.

You have three ways to get a new card: order one by phone, request one online through your Medicare account, or visit a Social Security office in person. The fastest option if you need proof of coverage today is to print a temporary card from Medicare.gov — it works when ready and is valid for 30 days while you wait for the permanent one.

Key Takeaways

  • You can see doctors and fill prescriptions without your physical card because Medicare identifies you by Social Security number.
  • Order a replacement card by calling 1-800-MEDICARE (1-800-633-4227), logging into your Medicare account online, or visiting a Social Security office.
  • A replacement card arrives in about 7 to 10 business days; a temporary printable card is available when ready on Medicare.gov.
  • If you have a Medicare Advantage or Part D plan through a private insurer, contact that company directly for a replacement card from them.
  • Report a lost or stolen card to Medicare if you suspect someone might use your information, though this is not required to order a replacement.

Order a replacement by phone or online

Call Medicare at 1-800-MEDICARE (1-800-633-4227) and tell them you lost your card. They will verify your identity by asking for your name, date of birth, and Social Security number. A new card will be mailed to the address Medicare has on file, usually within 7 to 10 business days.

If you prefer to order online, log into your Medicare account at Medicare.gov. Click "My Health Information" or "My Account," then look for an option to order a replacement card. You will need to sign in with your username and password. If you do not have an account, you can create one using your email address and Social Security number.

If your address has changed recently, update it before ordering. You can do this on Medicare.gov, by phone, or at a Social Security office. Mail can take longer if Medicare sends it to an old address.

Print a temporary card if you need coverage proof today

Go to Medicare.gov, sign into your account, and look for "View Your Medicare Card" or "Print Your Card." You can read and print a temporary card that shows your Medicare number and coverage type. This temporary card is valid for 30 days and works at doctors' offices, hospitals, and pharmacies just like your physical card.

Bring the temporary card with you to appointments or to the pharmacy. Most providers will accept it, though some older offices may ask you to bring your permanent card when it arrives. Keep the temporary card until your replacement arrives in the mail.

Visit a Social Security office in person

If you do not have internet access or prefer to handle this in person, go to your nearest Social Security office. Bring a photo ID and your Social Security card if you have it. The staff will verify your identity and order a replacement Medicare card, which will be mailed to you within 7 to 10 business days.

Find your local office at SSA.gov/locator or call 1-800-772-1213 to confirm hours before you go. Some offices require you to make an appointment in advance.

What to do if you have a Medicare Advantage or Part D plan

If your coverage is through a private insurance company — such as Humana, UnitedHealthcare, Aetna, or another Medicare Advantage or Part D plan — you need to contact that company directly, not Medicare. They issue their own cards with their logo and your plan details.

Call the customer service number on your latest bill or statement, or search the company's website for "order replacement card." They will verify your identity and mail a new card to you. This usually takes 7 to 10 business days as well.

While you wait, you can still see in-network doctors and fill prescriptions. Ask your doctor or pharmacy to look up your coverage using your name and date of birth, or provide your Medicare number (which you can find on any recent medical bill or statement).

Report a lost or stolen card if you are concerned about fraud

You do not have to report a lost card to Medicare to order a replacement. But if you think someone might use your information fraudulently, you can call 1-800-MEDICARE and let them know. They will make a note in your file.

Watch your Medicare statements and bills for charges you do not recognize. If you spot fraud, contact Medicare when ready and file a report with the Federal Trade Commission at ReportFraud.ftc.gov. Keep copies of any suspicious charges and the dates you reported them.

What your Medicare number is and where to find it

Your Medicare number is a unique identifier that Medicare uses to track your coverage and claims. It is printed on your Medicare card and is usually 11 characters long — typically your Social Security number followed by a letter or two.

If you need your Medicare number before your replacement card arrives, you can find it on any recent medical bill, hospital statement, or explanation of benefits (EOB) from Medicare. You can also log into your Medicare account on Medicare.gov and view your number there. Doctors and pharmacies can also look it up for you using your name and date of birth.

Frequently Asked Questions

Can I see my doctor without my Medicare card while I wait for a replacement?

Yes. Medicare identifies you by your Social Security number, not your card. Tell your doctor's office your name, date of birth, and Social Security number, and they can look up your coverage. Bring a photo ID for verification. If you want to show proof of coverage, print a temporary card from Medicare.gov.

How long does it take to get a replacement card in the mail?

Most replacement cards arrive within 7 to 10 business days. Mail times vary by location and postal delays. If you need proof of coverage sooner, print a temporary card from Medicare.gov, which is valid for 30 days.

What if I moved and my address changed since I lost my card?

Update your address with Medicare before ordering a replacement. You can do this on Medicare.gov, by calling 1-800-MEDICARE, or at a Social Security office. If you order a replacement before updating your address, the card will be mailed to your old address and you will have to reorder it.

Do I need to report my lost card to the police?

No. Reporting to police is not required to order a replacement Medicare card. You only need to report it to Medicare if you suspect fraud. If someone has used your information to file false claims, contact Medicare and the Federal Trade Commission.

What if I never received my replacement card after two weeks?

Call 1-800-MEDICARE and confirm that your address is correct and that your replacement order went through. If the card was mailed but lost in transit, they can reorder it or print a temporary card for you to use when ready.
