How to replace your Medicare card

You can order a replacement Medicare card online through your Medicare account, by phone, or by mail. The fastest way is online at Medicare.gov — you can request a new card in minutes if you have a login. If you do not have an online account, calling 1-800-MEDICARE (1-800-633-4227) takes about 10 minutes and a representative will mail one to you. A replacement card usually arrives within 7 to 10 business days.

You do not need to visit an office or provide documents in person. Medicare will send the card to the address on file with Social Security. If your address has changed recently, update it before you order so the card reaches you.

While you wait for your replacement card, you can still see your Medicare number and coverage information by logging into your Medicare account online or by calling the number above. Bring a photo ID and proof of address to any doctor's appointment if you do not have your physical card yet — most offices can look up your coverage by name and date of birth.

Ordering 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, Social Security number, and date of birth. Once logged in, look for the option to "Order a replacement Medicare card" — it is usually on the main dashboard or under "My Health Information."

The online form asks you to confirm your name, date of birth, and mailing address. Review this information carefully because Medicare will mail your new card to the address you confirm. If anything is wrong, correct it before you submit. Once you submit the request, you will see a confirmation number on the screen — write it down or take a screenshot.

You will receive an email confirmation as well. Keep this email until your card arrives. If your card does not show up within 14 days, you can use the confirmation number to check the status or contact Medicare.

Ordering by phone

Call 1-800-MEDICARE (1-800-633-4227) and tell the representative you need a replacement card. They will ask for your name, date of birth, Social Security number, and the mailing address where you want the card sent. Have your current address ready, and let them know if you have moved since you last received a Medicare card.

The representative will confirm your information and give you a confirmation number. Write down this number and the date you called. The call usually takes 10 to 15 minutes. Medicare is open Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday 8 a.m. to 7 p.m. Eastern time.

Ordering by mail

If you prefer to request a replacement card in writing, you can mail a letter to the Social Security Administration. Write a straightforward letter that includes your full name, date of birth, Social Security number, and current mailing address. State clearly that you are requesting a replacement Medicare card because yours is lost or damaged.

Mail your letter to: Social Security Administration, Office of Earnings and International Operations, 300 North Greene Street, Baltimore, MD 21290. This method takes longer — usually 3 to 4 weeks — because of mail delivery time. Use this option only if you cannot go online or make a phone call.

What to do if your address has changed

If you have moved since you got your current Medicare card, update your address with Social Security before you order a replacement. You can do this online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office.

When you order your replacement Medicare card, confirm that the address you provide is your current one. Medicare will mail the card to this address, so if it is wrong, your card may go to an old address and you will not receive it. If you realize after ordering that your address is incorrect, call 1-800-MEDICARE right away with your confirmation number and ask them to update it before the card ships.

Using your Medicare number while you wait

You do not have to wait for your physical card to arrive to use your Medicare coverage. Log into your Medicare account at Medicare.gov and your Medicare number will be displayed on the screen. You can also call 1-800-MEDICARE and a representative will read your number to you over the phone.

Write down your Medicare number or take a screenshot and keep it with you. When you go to a doctor's appointment, bring this number along with a photo ID. Your doctor's office can look up your coverage using your name, date of birth, and Medicare number even if you do not have the physical card yet.

If you need to show proof of coverage to an insurance company or employer, you can print a copy of your Medicare Summary Notice from your online account. This document shows your coverage details and your Medicare number.

What to do if your replacement card does not arrive

If your card does not arrive within 14 days of ordering, contact Medicare to check on it. Have your confirmation number ready. Call 1-800-MEDICARE and explain that you ordered a replacement card and have not received it yet. They can look up your order and tell you whether it has been mailed or if there is a problem.

If the card was lost in the mail, Medicare can send another one. If there was an error with your address, they can correct it and send a new card to the right place. Do not order a second replacement card until you have called to check the status of the first one, because ordering twice can cause confusion and delays.

Frequently Asked Questions

Is there a cost to replace a lost or damaged Medicare card?

No. Medicare does not charge you to replace a card. If someone asks you to pay for a replacement card, it is a scam. Always order through Medicare.gov, by calling 1-800-MEDICARE, or by mail to Social Security — never through a third-party website or phone number.

Can I get a replacement card faster than 7 to 10 days?

Standard replacement takes 7 to 10 business days. There is no expedited or overnight option. If you need your Medicare number urgently, log into your account online or call 1-800-MEDICARE to get it when ready — you do not have to wait for the physical card.

What if I lost my card and someone else might have it?

Order a replacement right away. Your Medicare card has your Social Security number on it, so a lost card is a security risk. Once you order the replacement, the old card becomes invalid when the new one is issued. If you are concerned about fraud, you can also place a fraud alert with the three credit bureaus by calling Equifax, Experian, or TransUnion.

Do I need to tell my doctor that I lost my card?

You do not need to notify your doctor. When you go to your next appointment, just bring your Medicare number (which you can get online or by phone) and a photo ID. Your doctor's office will update their records with your new card number once it arrives and you show it to them.

What if my name has changed since I got my Medicare card?

Contact Social Security to update your name first. You can do this online at ssa.gov, by phone at 1-800-772-1213, or in person at a local Social Security office. Once your name is updated with Social Security, order your replacement Medicare card and your new card will have the correct name on it.
