You can order a replacement Medicare card online, by phone, or by mail in about 5 to 10 business days

If your Medicare card is lost, stolen, damaged, or you need a new one because your name changed, you have three ways to get a replacement. The fastest method is ordering online through your Medicare account at Medicare.gov. If you don't have an online account, you can call 1-800-MEDICARE (1-800-633-4227) or mail a request to your local Social Security office. Most people receive their new card within 5 to 10 business days, though it can take longer during peak times.

You don't need to visit an office in person, and there is no cost for a replacement card. The process is straightforward once you know which method works best for your situation.

Key Takeaways

  • Order online at Medicare.gov if you have an account — this is the fastest option and takes about 5 to 10 business days.
  • Call 1-800-MEDICARE if you don't have an online account or prefer to speak with someone; representatives can process your request over the phone.
  • Mail a request to your local Social Security office if you cannot go online or use the phone, though this method takes longer.
  • Have your Social Security number and date of birth ready no matter which method you choose.
  • If your card was stolen, report it to Medicare and Social Security to protect against fraud.

Ordering online through your Medicare account

The online method is the quickest and most convenient. Go to Medicare.gov, sign in to your account with your username and password, and look for the option to order a replacement card. If you don't have a Medicare.gov account yet, you can create one using your email address, Social Security number, and date of birth. The site will walk you through the setup.

Once you're signed in, select "Order a replacement Medicare card" from your account menu. You'll confirm your name, address, and the reason you need a replacement (lost, stolen, damaged, or name change). Submit your request, and you're done. You should see a confirmation message right away, and your card will arrive by mail within 5 to 10 business days.

Keep the confirmation number the site gives you. If your card doesn't arrive within two weeks, you can use that number to check the status of your order.

Calling Medicare to request a replacement card

Call 1-800-MEDICARE (1-800-633-4227) if you prefer to speak with a representative or don't have internet access. The line is open Monday through Friday, 8 a.m. to 8 p.m. Eastern time. On Saturday, hours are 9 a.m. to 1 p.m. Eastern time. Have your Social Security number and date of birth ready when you call.

Tell the representative that you need a replacement card and explain why (lost, stolen, damaged, or name change). They will confirm your address and process your request. Ask for a confirmation number before you hang up so you can track your order if needed. Your new card should arrive within 5 to 10 business days.

If you have hearing or speech difficulties, you can use the TTY number 1-877-486-2048. If you speak a language other than English, interpreters are available at no cost.

Mailing a request to Social Security

You can also mail a request for a replacement Medicare card to your local Social Security office. First, find your office at ssa.gov/locator or call 1-800-772-1213 to get the mailing address. Write a straightforward letter that includes your name, Social Security number, date of birth, current address, and the reason you need a replacement card.

Mail your letter to the address provided. This method takes longer than online or phone — usually 2 to 3 weeks or more depending on mail delivery and office workload. Include a phone number in your letter so Social Security can contact you if they need more information.

What to do if your card was stolen

If your Medicare card was stolen rather than lost, take extra steps to protect yourself from fraud. Call Medicare at 1-800-MEDICARE and report the theft. Also contact Social Security at 1-800-772-1213 to report that your Social Security number may be at risk. Both agencies can flag your account and watch for suspicious activity.

Check your Medicare statements and billing records regularly for charges you don't recognize. If you see fraud, report it to Medicare right away. You can also place a fraud alert on your credit report by contacting one of the three major credit bureaus: Equifax, Experian, or TransUnion.

Replacing a card due to name change

If you changed your name because of marriage, divorce, or another reason, you'll need a new Medicare card that shows your current name. The process is the same — order online, call, or mail a request — but you'll need to have already updated your name with Social Security first.

To update your name with Social Security, visit your local Social Security office in person with proof of your legal name change (marriage certificate, divorce decree, or court order). Once Social Security has your new name on file, Medicare will automatically update their records. You can then order your new Medicare card with your current name.

Tracking your replacement card

After you order your card, you can check on its status if you ordered online or by phone. If you ordered online, sign back into your Medicare.gov account and look for order status information. If you called, use the confirmation number the representative gave you and call 1-800-MEDICARE again to ask about your order.

If your card doesn't arrive within two weeks, call Medicare. Sometimes cards are delayed in the mail, but the agency can investigate and send a replacement if needed. Have your confirmation number ready when you call.

Frequently Asked Questions

Can I use my old Medicare card while I wait for the replacement?

Yes, your old card remains valid until your new one arrives. If your card was stolen, call Medicare to report it so they can watch for fraud, but you can still use your Social Security number for Medicare services in the meantime.

Do I need to bring anything to an office to get a replacement card?

No. You do not need to visit an office. You can order your replacement card entirely online, by phone, or by mail. Medicare mails the card to your address on file.

What if my address changed since I got my current Medicare card?

Update your address with Medicare before you order your replacement card. Call 1-800-MEDICARE or update it online through your Medicare.gov account. Your new card will be mailed to your current address.

How much does a replacement Medicare card cost?

There is no cost. Replacement cards are free. Be cautious of websites or services that charge a fee to help you order a card — you can do it yourself at no charge.

What if I never received my original Medicare card?

Treat it the same way as a lost card. Order a replacement online, by phone, or by mail. Medicare will send you a new card to your address on file.
