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

If your Medicare card is lost, stolen, damaged, or you need a new one because your name changed, you have three ways to request a replacement. The online method through your Medicare account takes a few minutes and you can track your order. Calling Medicare directly is faster if you do not have online access. Mailing in a form works but takes longer. Your replacement card will arrive by mail in 7 to 10 business days in most cases, though this can vary by region.

You do not need to visit an office in person, and there is no cost for a replacement card. You can start the process right now even if your current card is damaged or missing — you do not need to have it in front of you.

Ordering a replacement card online through your Medicare account

Go to Medicare.gov and sign in to your account using your username and password. If you do not have an account yet, you can create one using your email address, Social Security number, and date of birth. Once you are signed in, look for the option to order a replacement card — this is usually under "My Health Information" or "Manage Your Health Information."

Select the reason your card needs to be replaced (lost, stolen, damaged, or name change), then confirm your mailing address. Medicare will send the card to the address on file. Review the information one more time before you submit, then you will see a confirmation number. Write down or screenshot this number — you can use it to track your order status on Medicare.gov.

This method usually takes 5 to 10 minutes and you can do it any time, day or night. You will receive an email confirmation, and you can check the status of your order by signing back into your account.

Calling Medicare to request a replacement card

Call 1-800-MEDICARE (1-800-633-4227). The line is open Monday through Friday, 8 a.m. to 8 p.m. Eastern time. Have your Social Security number and date of birth ready. A representative will ask why you need a replacement card and will confirm your mailing address.

The call usually takes 5 to 10 minutes. You will receive a confirmation number — write it down. The representative may also give you a tracking number so you can check on your card's status by calling back or visiting Medicare.gov.

If you are deaf or hard of hearing, call 1-877-486-2048 (TTY). If you speak a language other than English, Medicare has interpreters available — tell the representative your language when you call.

Mailing in a request form

You can read the form "process for a Social Security Card" (Form SS-5) from the Social Security Administration website, or you can request a replacement card directly through Medicare by mailing a letter. The letter should include your name, date of birth, Social Security number, current mailing address, and the reason you need a replacement card.

Mail your request to the Medicare address for your state. You can find the correct address by calling 1-800-MEDICARE or visiting Medicare.gov. This method takes the longest — expect 2 to 3 weeks for your card to arrive after Medicare receives your request.

Keep a copy of anything you mail for your records. If you are concerned about your card being lost in the mail, the online or phone method is a safer choice.

What to do if your name has changed

If you got married, divorced, or changed your name for another reason, you need to update your Medicare records before you order a new card. You cannot order a replacement card with a new name until Medicare's system shows the name change.

Call 1-800-MEDICARE to update your name. Have your Social Security number, date of birth, and the legal document that shows your name change (marriage certificate, divorce decree, or court order) ready. The representative will walk you through the update process. Once your name is changed in the system, you can order your new card using any of the three methods above.

The name change itself usually takes 1 to 2 weeks to show up in Medicare's system. After that, you can order your replacement card.

Tracking your replacement card and what to expect

When you order online, you will receive a confirmation number and can track your order status by signing into Medicare.gov. When you call, write down the confirmation or tracking number the representative gives you. You can call 1-800-MEDICARE again and give them this number to check on your card's status.

Your card will arrive in a plain envelope with your name and address on it. It will come from the Social Security Administration on behalf of Medicare. Open it as soon as it arrives and check that all the information is correct — your name, date of birth, and Medicare number should all match your records.

If your card arrives damaged or with incorrect information, call 1-800-MEDICARE right away to request another replacement. Do not use a card with wrong information.

What to do while you wait for your new card

You do not need your physical card to see a doctor or use your Medicare coverage while you wait for the replacement to arrive. Your coverage is active as soon as you are enrolled in Medicare, whether or not you have the card in hand.

When you visit a doctor or hospital, you can give them your Medicare number verbally, and they can look up your information in their system. If they ask for proof, you can show them a printout of your Medicare information from Medicare.gov, or you can call 1-800-MEDICARE and ask them to provide your information to the provider.

Keep the confirmation number from your replacement order in a safe place until your new card arrives. This number proves you requested the replacement if anyone questions your coverage.
