How to get a copy of your Medicare card
You can get a replacement Medicare card three ways: online through your Medicare account, by phone, or by mail. The fastest route is online if you have a Medicare.gov account set up — you can request a card and it arrives in 7 to 10 business days. If you do not have an online account yet, calling Medicare directly takes about 15 minutes and produces the same result. Mail requests take longer but work if you prefer not to use the phone or internet.
You will need your Social Security number and date of birth to request a card, no matter which method you choose. If you are requesting a card for someone else — a spouse, parent, or someone you care for — you will need their Social Security number and date of birth instead, and you may need to show that you have authority to act on their behalf.
Key Takeaways
- The online method through Medicare.gov is fastest: request a card and receive it in 7 to 10 business days if you have an account set up.
- Calling 1-800-MEDICARE (1-800-633-4227) takes about 15 minutes and works whether or not you have an online account.
- You need your Social Security number and date of birth to request a card by any method.
- Temporary cards are not available, so plan ahead if you need your card for an appointment — bring your Social Security card or other ID instead.
Requesting your card online through Medicare.gov
Go to Medicare.gov and sign in to your 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 to order a replacement card — this is usually under "My Health Information" or "Medicare Card" depending on the page layout.
Click the button to order a new card and confirm your mailing address. Medicare will send the card to the address on file with Social Security unless you update it first. Double-check the address before you submit, because the card will go there regardless. After you submit your request, you will see a confirmation number — write it down or take a screenshot in case you need to check on your order later.
Your new card should arrive within 7 to 10 business days. If more than two weeks pass and you have not received it, call 1-800-MEDICARE to check the status using your confirmation number.
Requesting your card 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 your current mailing address and ask whether you want the card sent there or to a different address.
The call usually takes 10 to 15 minutes. At the end, you will receive a confirmation number — write it down. Your card will arrive in 7 to 10 business days. Medicare's phone lines are open Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday, 8 a.m. to 4 p.m. Eastern time. If you call outside these hours, you can leave a message and a representative will call you back, though this adds a few days to the process.
Requesting your card by mail
Fill out Form CMS-40B, the process for Enrollment in Medicare, and mail it to your state's Social Security office. You can read the form from Medicare.gov or ask for it by calling 1-800-MEDICARE. The form asks for your name, Social Security number, date of birth, and current mailing address.
Mail the completed form to the address listed on the form itself — this varies by state. Include a copy of proof of citizenship or legal residency if this is your first time requesting a Medicare card, though replacement requests usually do not require this. Mail requests take 2 to 4 weeks longer than phone or online requests, so use this method only if you cannot use the phone or internet.
What to do if you need your card before it arrives
Medicare does not issue temporary cards, so if you have a doctor's appointment or need to use your Medicare benefits before your new card arrives, bring a different form of ID instead. Your Social Security card, driver's license, or passport all work. Tell the doctor's office or pharmacy that you have requested a replacement card and provide your Medicare number if you know it — you can find your number by calling 1-800-MEDICARE or logging into your Medicare account online.
If you are in an urgent situation — for example, you need to show proof of coverage for a hospital stay — call 1-800-MEDICARE and ask them to note in your file that you have a replacement card on the way. Some facilities will accept a verbal confirmation from Medicare in place of the physical card.
Requesting a card for someone else
If you are requesting a card for a spouse, parent, or someone you care for, you can do so online or by phone using their Social Security number and date of birth. You do not need special legal authority to request a replacement card for someone else — Medicare assumes you have a legitimate reason if you have their personal information.
If you are the legal representative or power of attorney for someone and need to handle their Medicare matters regularly, you can set up authorized representative access on their Medicare account. This gives you ongoing access to their information and lets you make changes on their behalf. Call 1-800-MEDICARE and ask about setting up authorized representative status — you will need the person's permission and may need to provide legal documents showing your authority.
What to do if your card is lost, stolen, or damaged
Request a replacement card the same way you would request a duplicate — online, by phone, or by mail. There is no separate process for lost or stolen cards. If your card was stolen and you are concerned about fraud, call 1-800-MEDICARE right away and ask them to flag your account. They can monitor your Medicare claims for unusual activity.
If your card is damaged but still readable, you can continue using it until your replacement arrives. If it is unreadable, request a new one when ready so you do not miss any appointments or prescriptions while waiting.
Frequently Asked Questions

What if I do not know my Medicare number?
Call 1-800-MEDICARE with your Social Security number and date of birth, and they will give you your Medicare number over the phone. You can also log into your Medicare account online to find it, or check any past Medicare statements or bills.

What if my address has changed since I got my first card?
When you request a replacement card online or by phone, you can update your address at that time. The new card will be sent to your updated address. If you have already submitted a request and need to change the address, call 1-800-MEDICARE with your confirmation number and they can update it before the card ships.
