The fastest way to order a new Medicare card

You can order a replacement Medicare card online through Medicare.gov without calling or visiting an office. Go to ssa.gov/myaccount (the Social Security website), sign in with your username and password, and select "Order a replacement Social Security card" — Medicare uses your Social Security number, so the two are linked. If you do not have a Social Security account yet, you can create one at the same website.

The online order takes about 10 minutes. Medicare will mail your new card to the address on file, usually within 7 to 10 business days. You do not need to bring documents or visit an office. If you prefer to order by phone instead, you can call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) Monday through Friday, 8 a.m. to 7 p.m. Eastern time.

If your address has changed since you last updated Medicare, update it first before ordering the card. You can change your address on Medicare.gov under "My Account" or by calling Medicare directly at 1-800-MEDICARE (1-800-633-4227).

Key Takeaways

  • Order online at ssa.gov/myaccount by signing into your Social Security account, or call Social Security at 1-800-772-1213 to order by phone.
  • A replacement card arrives by mail in 7 to 10 business days at no cost.
  • Update your mailing address with Medicare before ordering if you have moved since your last card was issued.
  • You will need your Social Security number and a valid ID to set up or access your Social Security account online.
  • If you lose your card before the replacement arrives, you can still use your Medicare number to see doctors — the number is what matters, not the physical card.

When you need a new Medicare card

Order a replacement if your card is lost, stolen, damaged, or illegible. You also need a new card if your name has changed — for example, after marriage or a legal name change — or if your Medicare number has changed. Most people keep the same Medicare number for life, but changes do happen, and Medicare will tell you if yours has changed.

If you have not received your original Medicare card yet, the same process applies. New beneficiaries should receive a card automatically within two weeks of their coverage start date, but if yours has not arrived after three weeks, order a replacement using the steps above.

What to do if you need your Medicare number before the card arrives

Your Medicare number is printed on your card, but you do not have to wait for the physical card to use it. You can find your Medicare number right away by logging into your Medicare account at Medicare.gov — it appears under "My Health Information." You can also call Medicare at 1-800-MEDICARE and a representative will read your number to you over the phone.

When you see a doctor or fill a prescription, you can give them your Medicare number verbally or write it down from your online account. Pharmacies and medical offices have your number in their systems once you provide it, so you do not need the physical card in your wallet to receive care. The card itself is a convenience, not a requirement.

Ordering a card for someone else

If you are helping a family member or someone you care for order a replacement card, they must request it themselves or give you written permission. You cannot order a card on someone else's behalf without their authorization. The person whose name is on the card should either create their own Social Security account and order online, or call Social Security directly.

If the person you are helping cannot manage the online process or phone call due to illness or disability, ask Social Security about power of attorney or representative payee options. These legal arrangements allow you to handle certain tasks on their behalf, but they require paperwork filed in advance.

If your name has changed

When you order a replacement card after a legal name change, Medicare will update your name automatically once the new card is processed. You do not need to contact Medicare separately. However, you should also update your name with Social Security if it has changed — the online account process will prompt you to do this, or you can call Social Security at 1-800-772-1213.

Bring proof of your name change to any doctor's office or pharmacy where your records are under your old name. A marriage certificate, divorce decree, or court order for a legal name change will allow them to update their files. This prevents confusion when claims are processed.

Protecting your Medicare card and number

Your Medicare number is as sensitive as your Social Security number — do not share it with anyone who calls you unsolicited or sends you an email asking for it. Medicare will never contact you first asking for your number, and legitimate doctors' offices already have it in their system.

Keep your physical card in a safe place at home, not in your wallet where it can be lost or stolen. Write down your Medicare number and store it separately in case you need it before your replacement arrives. If you suspect your number has been used fraudulently, call Medicare when ready at 1-800-MEDICARE to report it.

Frequently Asked Questions

How long does it take to get a replacement Medicare card?

Most replacement cards arrive within 7 to 10 business days of ordering. If you order online, the processing time is usually the same as ordering by phone. If your card has not arrived after two weeks, call Medicare at 1-800-MEDICARE to check the status.

Is there a cost to order a replacement card?

No. Medicare replacement cards are free. If someone offers to charge you for a Medicare card, it is a scam. Hang up or delete the message and report it to Medicare at 1-800-MEDICARE.

What if I moved and my card was sent to my old address?

Update your address with Medicare first at Medicare.gov or by calling 1-800-MEDICARE, then order a new card. The replacement will go to your current address. If your old card arrived at your previous home, ask the current residents to return it to you, or contact your local post office to see if they can forward it.

Can I use my Medicare number if my card is lost?

Yes. Your Medicare number is what doctors and pharmacies need — the physical card is just a reference. You can provide your number verbally or in writing, or look it up online at Medicare.gov. You do not need the card itself to receive care.

What should I do if my card is stolen?

Call Medicare at 1-800-MEDICARE right away to report it. Order a replacement using the steps above. Monitor your medical bills and explanation of benefits statements for the next few months to watch for fraudulent claims. If you see charges you did not authorize, report them to Medicare and your doctor's office when ready.
