How to Request Your New Medicare Card

You can request a replacement Medicare card online through your Medicare account, by phone, or by mail. The online method is fastest — you can submit your request in about five minutes and the card arrives in 7 to 10 business days. If you do not have internet access or prefer to speak with someone, calling Medicare directly takes about the same time to process, though the card still takes the same number of days to arrive by mail.

You will need your Social Security number, date of birth, and current mailing address. If your name has changed since your Medicare started, bring documentation of the change — a marriage certificate, divorce decree, or court order. If you have moved recently, update your address first through your Medicare account or by calling, because Medicare will mail the card to whatever address is on file.

Key Takeaways

  • Request a new card online at Medicare.gov by signing into your account, which is the fastest method and takes about five minutes.
  • You can also call 1-800-MEDICARE (1-800-633-4227) to request a card by phone, and the process takes the same time as online but requires speaking with a representative.
  • Medicare mails replacement cards to the address on file, so update your address before requesting if you have moved recently.
  • A replacement card takes 7 to 10 business days to arrive after your request is processed, regardless of which method you use.
  • If your name has changed, you will need to provide proof of the change — such as a marriage certificate or court order — when you request the new card.

Requesting Online Through Your Medicare Account

Go to Medicare.gov and 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. Once you are logged in, look for the option labeled "Get a replacement Medicare card" or "Order a new card" — the exact wording changes, but it is always in the main menu or under "My Health Information."

Click that option and confirm your current mailing address. If the address shown is wrong, correct it before you submit. Then select "Order card" or "Submit request" — the system will show you a confirmation number. Write down this number or take a screenshot. Medicare will send the card to the address you confirmed, and you should receive it within 7 to 10 business days.

If you run into trouble signing in, use the "Forgot username or password?" link on the Medicare.gov login page. If you cannot create an account or the system will not let you order a card online, call 1-800-MEDICARE instead — this sometimes happens if your account has a flag or if there is a recent change to your file.

Requesting by Phone

Call 1-800-MEDICARE (1-800-633-4227). Have your Social Security number, date of birth, and current mailing address ready. The representative will confirm your identity by asking you to verify this information, then ask why you need a new card — common reasons are "lost," "damaged," or "name change."

Tell them your current address and confirm it is correct. If you have moved, give them your new address now. If your name has changed, let them know and be ready to describe what changed — for example, "I got married and changed my last name." They may ask you to mail in proof of the name change, or they may process it over the phone depending on the type of change.

The representative will give you a confirmation number. Write it down. The card will be mailed to the address you confirmed, arriving in 7 to 10 business days. Medicare phone lines are busiest early in the morning and on Mondays, so calling in the afternoon or mid-week usually means a shorter wait.

If Your Name Has Changed

When you request a new card and your name is different from what Medicare has on file, you must provide proof of the change. Acceptable documents include a marriage certificate, divorce decree, court order for a legal name change, or adoption papers. You do not need to send the original — a copy is fine.

If you are requesting online, the system will tell you whether you need to mail in proof or if it can be handled through your account. If you are calling, the representative will tell you the same thing. If proof is needed by mail, they will give you an address and a reference number to include with your documents. Mail the proof and keep a copy for your records.

Processing a name change takes longer than a routine replacement — usually 2 to 4 weeks instead of 7 to 10 days — because Medicare has to update your file before printing the card. If you need the card urgently, ask the representative whether Medicare can issue a temporary card number while the new card is being printed.

What to Do If Your Card Does Not Arrive

If 10 business days have passed and you have not received your card, check your mailing address first. Log into your Medicare account and look at the address on file. If it is wrong, that is why the card did not arrive. Update it and request a new card.

If the address is correct, call 1-800-MEDICARE with your confirmation number from when you placed the order. They can check the status of your card and tell you whether it has been mailed. If it has been mailed but lost in transit, they can issue a replacement. If it has not been mailed yet, they can investigate why.

Do not request multiple cards at once thinking one will arrive faster — this can cause confusion in your file and delay all of them. Wait at least 10 business days before calling to check on a card.

Using Your Social Security Number as a Temporary Card Number

While you wait for your new Medicare card to arrive, you can use your Social Security number as your Medicare number when you see a doctor or fill a prescription. Doctors' offices and pharmacies have your Social Security number on file from previous visits, so they can look up your coverage without the card.

Tell the doctor's office or pharmacy that you have ordered a new card and provide your Social Security number. They will enter it into their system and your Medicare coverage will come up. This works for all routine visits and prescriptions. You do not need to wait for the physical card to arrive to use your benefits.

Frequently Asked Questions

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

Most replacement cards arrive in 7 to 10 business days after you submit your request. If your name has changed and you need to mail in proof, add 2 to 4 weeks to that timeline because Medicare has to update your file first. Weekends and federal holidays do not count as business days.

Can I get a temporary card number while I wait?

You can use your Social Security number as your Medicare number at any doctor or pharmacy while your new card is on the way. If you need an actual temporary card number — which is rare — call 1-800-MEDICARE and ask. They can issue one in some situations, though most people do not need it.

What if I never received my original Medicare card?

Request a replacement card using the same process as if you lost it. You will need your Social Security number and date of birth. If you have never had a card, call 1-800-MEDICARE to confirm your Medicare coverage is active, because sometimes enrollment issues prevent a card from being issued in the first place.

Do I have to pay for a replacement card?

No. Medicare does not charge for replacement cards. If anyone asks you to pay for a Medicare card, it is a scam. Request your card only through Medicare.gov, by calling 1-800-MEDICARE, or by mailing a request directly to Medicare — never through a third-party website or phone number.

Can I request a card for someone else?

No. Each person must request their own card using their own Social Security number and identity. If you are helping an older relative or family member, they can authorize you to manage their Medicare account, which lets you request a card on their behalf. To set this up, they log into their Medicare account and add you as an authorized representative.
