You can request a replacement Medicare card online, by phone, or by mail — the fastest route is usually the online method through your Medicare account

A lost or damaged Medicare card does not stop your coverage. Your benefits stay active as long as your premiums are paid. However, you will need proof of your Medicare number to see a doctor or fill a prescription, so getting a replacement is worth doing soon.

The three ways to request a replacement are: online through your personal Medicare account (takes 7 to 10 business days), by phone to Social Security (takes 7 to 10 business days), or by mail (takes 2 to 4 weeks). You do not need to visit an office in person. Your new card will arrive by standard mail at the address Social Security has on file.

You will need your Social Security number and date of birth to start any of these requests. If your address has changed since you enrolled, update it first — otherwise your new card may go to the wrong place.

Key Takeaways

  • The online method through Medicare.gov is fastest if you have set up a personal account and remember your login.
  • Calling Social Security at 1-800-772-1213 (TTY 1-800-325-0778) works if you do not have an online account, and the representative can confirm your address while you are on the phone.
  • Your Medicare coverage does not stop while you wait for a replacement card — you can still see doctors and use your benefits.
  • If you need proof of coverage before your card arrives, you can print a temporary notice from your Medicare account or ask Social Security to mail one.
  • A replacement card costs nothing and should arrive within 7 to 10 business days if you request it online or by phone.

Requesting a Replacement Card Online

Go to Medicare.gov and sign in to your personal account. If you do not have an account, you can create one using your email address, Social Security number, and date of birth. Once you are signed in, look for the option labeled "Order a Replacement Medicare Card" or "Replace Your Card" — the exact wording varies slightly depending on when the site was last updated.

Click through to confirm your name, date of birth, and mailing address. If your address is wrong, correct it now — this is your only chance to fix it before the card is printed. Review the information one more time, then submit your request. You will see a confirmation number on screen; write it down or take a screenshot.

Your new card will be mailed to the address you confirmed. Standard delivery takes 7 to 10 business days. If you need proof of coverage before it arrives, you can print a temporary notice from the same Medicare account — look for "View Your Medicare Summary" or "Print Your Coverage Information".

Requesting a Replacement Card by Phone

Call Social Security at 1-800-772-1213. If you are deaf or hard of hearing, use the TTY number 1-800-325-0778. Have your Social Security number and date of birth ready before you call.

Tell the representative that your Medicare card is lost or damaged and you need a replacement. They will confirm your name, address, and date of birth. If your address has changed, tell them now — they can update it while you are on the phone, and your new card will go to the correct location.

The representative will give you a confirmation number. Write it down. Your card will arrive by mail in 7 to 10 business days. If you need proof of coverage before then, ask the representative if they can mail you a temporary notice or direct you to print one online.

Social Security's phone lines are busiest early in the week and early in the month. If you reach a long wait time, try calling back later in the week or later in the month.

Requesting a Replacement Card by Mail

Print or request Form CMS-1763 from Medicare.gov, or call 1-800-MEDICARE (1-800-633-4227) and ask them to mail you the form. Fill it out completely, including your name, date of birth, Social Security number, and current mailing address.

Mail the completed form to the address listed on the form itself — this varies by region. Include a copy of your ID if possible, though it is not required. Mail delivery is slower than online or phone requests; expect 2 to 4 weeks for your new card to arrive.

Keep a copy of the form for your records. If you do not hear back within 4 weeks, call 1-800-MEDICARE to check the status.

What to Do If Your Address Has Changed

If you have moved since you enrolled in Medicare, update your address before you request a replacement card. A new card sent to an old address will not reach you, and you will have to request another one.

You can update your address online through your Medicare account, by phone to Social Security, or by mail. The online method is fastest — sign in to Medicare.gov, find "Personal Information" or "Update Your Information", and change your address there. If you call Social Security, the representative can update it when ready while you are on the phone.

Getting Proof of Coverage While You Wait

Your Medicare coverage is active even without a physical card in your hand. If you need to prove you have coverage before your replacement card arrives, you have two options.

First, sign in to your Medicare account at Medicare.gov and look for "View Your Medicare Summary" or "Print Your Coverage Information". You can print this page and show it to your doctor or pharmacy — it includes your Medicare number and coverage details.

Second, if you do not have an online account, call 1-800-MEDICARE and ask them to mail you a temporary notice of coverage. This takes a few days to arrive but serves the same purpose.

Common Mistakes to Avoid

Do not wait to update your address if you have moved. A replacement card sent to your old address will not reach you, and you will have to start over.

Do not assume your coverage has stopped just because you lost your card. It has not. Your benefits remain active as long as your premiums are paid. You can still see doctors and use your coverage while waiting for a replacement.

Do not give your Medicare number to anyone who calls you claiming to be from Medicare or Social Security. Medicare and Social Security do not call people unsolicited. If someone calls asking for your number, hang up and call the official number yourself.

Do not pay anyone to replace your card. The replacement is free. If a website or person offers to replace your card for a fee, it is a scam.

Frequently Asked Questions

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

Online and phone requests take 7 to 10 business days. Mail requests take 2 to 4 weeks. Business days do not include weekends or federal holidays. If your card does not arrive within these timeframes, call 1-800-MEDICARE to check the status.

Can I use my Medicare coverage before my replacement card arrives?

Yes. Your coverage is active regardless of whether you have the physical card. You can give your doctor or pharmacy your Medicare number from memory, or print a temporary coverage notice from your online account. Both work until your new card arrives.

What if I need my card urgently for a doctor's appointment?

Call your doctor's office and give them your Medicare number over the phone. They can look up your coverage in their system. You can also print a temporary coverage notice from Medicare.gov or ask Social Security to mail one. Neither requires you to wait for the physical card.

Do I have to pay for a replacement card?

No. Replacement Medicare cards are free. If anyone asks you to pay, it is a scam. Request your replacement through Medicare.gov, by phone to Social Security, or by mail — all three methods are free.

What if my name has changed since I enrolled?

Call Social Security at 1-800-772-1213 with proof of your name change (marriage certificate, divorce decree, or court order). They will update your name in the system. Your replacement card will be printed with your new name.
