Replacing a lost, stolen, or washed-out Medicare card is free, and one option lets you print an official copy yourself instead of waiting for the mail. The steps below cover each way to do it, how long a mailed card takes, and the one extra thing to do if your card was stolen rather than misplaced.
Start here: choosing how to replace your card
There's no cost to replace a Medicare card, no matter why you need one. The right method depends on whether you'd rather print a copy yourself or have one mailed.U.S. Social Security Administration.

The Four Ways to Replace Your Medicare Card
Most people use one of the first two. All of them are free, and each one gets you a replacement for your Medicare card.U.S. Social Security Administration. (n.d.). How do I get a replacement Medicare card?. ssa.gov. Retrieved Jul 30, 2026, from https://www.ssa.gov/faqs/en/questions/KA-01735.html
1. Online at Medicare.gov. Sign in to your secure Medicare account, or create one if you've never set it up, where you can print an official copy of your card or order one to be mailed. Printing it yourself means you aren't waiting on the mail, which helps if you need the number for an appointment this week. The official rundown lives on the Your Medicare Card page.U.S. Social Security Administration. (n.d.). How do I get a replacement Medicare card?. ssa.gov. Retrieved Jul 30, 2026, from https://www.ssa.gov/faqs/en/questions/KA-01735.html
2. By phone. Call 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048) and ask a representative to send a replacement card in the mail.

Retrieved Jul 30, 2026, from https://www.ssa.gov/faqs/en/questions/KA-01735.html
3. Through the Railroad Retirement Board. If you get Railroad Retirement benefits, your Medicare card is issued by the Railroad Retirement Board (RRB) rather than Social Security, so you request a replacement from the RRB. Call the RRB at 1-877-772-5772 (TTY 1-312-751-4701); the RRB mails the card to the address on record within 30 days, and its replacement card page notes that if you need immediate proof of your Medicare coverage in the meantime, you can print a paper copy of your card from your Medicare.gov account.U.S. Social Security Administration. (n.d.). How do I get a replacement Medicare card?. ssa.gov. Retrieved Jul 30, 2026, from https://www.ssa.gov/faqs/en/questions/KA-01735.html
4. As a representative payee, for someone else. If Social Security has named you the representative payee for a beneficiary, you request their replacement card through your own personal my Social Security account, under Representative Payee Services. The card arrives in about 30 days at the payee address SSA has on file.U.S. Social Security Administration. (n.d.). How do I get a replacement Medicare card?. ssa.gov.

How long it takes, and how often you can ask
Medicare doesn't publish a delivery window for a mailed replacement card, so plan around ordinary mail rather than a promised date. If you need the number for an upcoming appointment, use the print option in your Medicare.gov account instead, which gives you an official copy without waiting on the mail. The Your Medicare Card page is the official rundown of both routes. Two timelines are published: the Railroad Retirement Board mails a replacement to the address on record within 30 days, and a representative payee's request arrives in about 30 days.U.S. Social Security Administration. (n.d.). How do I get a replacement Medicare card?. ssa.gov. Retrieved Jul 30, 2026, from https://www.ssa.gov/faqs/en/questions/KA-01735.html
One limit applies to representative payees: you can request only one replacement card per beneficiary in a 30-day period, so make the request count. No federal page states a comparable cap on a beneficiary's own request for their own card.U.S. Social Security Administration. (n.d.). How do I get a replacement Medicare card?. ssa.gov. Retrieved Jul 30, 2026, from https://www.ssa.gov/faqs/en/questions/KA-01735.html
If the mailed card is taking longer than you expected, don't wait indefinitely. Log in to your Medicare.gov account and print an official copy so you have your number in hand, and call 1-800-MEDICARE (1-800-633-4227) to check on the order or place a new one. Railroad retirees should call the RRB at 1-877-772-5772 instead.U.S. Social Security Administration. (n.d.). How do I get a replacement Medicare card?. ssa.gov.

What's the Number on Your Medicare Card?
The card shows your Medicare Beneficiary Identifier (MBI), a unique, randomly generated 11-character code made of numbers and uppercase letters. It isn't based on your Social Security number. It replaced the old Social Security number-based Medicare number, and CMS treats it as confidential, the same way it treats a Social Security number.Centers for Medicare & Medicaid Services. (n.d.).

CMS began mailing the new MBI cards in April 2018 and replaced all Medicare cards by April 2019. If you have a Medicare Advantage or Part D plan, you'll use your plan's card to get services, but keep the Medicare card itself in a safe place in case you switch plans or go back to Original Medicare later.U.S. Social Security Administration.

If your card was stolen, not just lost
A misplaced card and a stolen one call for different responses. If you simply lost the card, replacing it is the whole task. If it was stolen, replace it and then watch for fraud, because a Medicare number in the wrong hands can be used for medical identity theft, where someone bills Medicare for care you never got.Centers for Medicare & Medicaid Services. (n.d.). Reporting Medicare fraud & abuse. medicare.gov. Retrieved Sep 2, 2026, from https://www.medicare.gov/basics/reporting-medicare-fraud-and-abuse
Two steps protect you:
- Review your claims. If you have Original Medicare, check your Medicare Summary Notices; if you're in a Medicare Advantage or Part D plan, check your Explanation of Benefits. Both list the dates and services billed to your number, so compare them against care you actually received. You don't have to wait for the mailed notice: a secure account at Medicare.gov lets you view your Original Medicare claims as they post. Charges for visits, equipment, or services you don't recognize are the warning sign.Centers for Medicare & Medicaid Services. (n.d.). Reporting Medicare fraud & abuse. medicare.gov. Retrieved Sep 2, 2026, from https://www.medicare.gov/basics/reporting-medicare-fraud-and-abuse
- Report anything suspicious. Call 1-800-MEDICARE to report Medicare fraud (1-800-633-4227), and see our guide to spotting and reporting Medicare fraud for the full process, including the Senior Medicare Patrol (SMP), present in all 50 states, DC, Guam, Puerto Rico, and the U.S. Virgin Islands, which helps beneficiaries and families prevent, detect, and report suspected fraud.Centers for Medicare & Medicaid Services.

Guard the card like a credit card
The simplest protection is treating your Medicare card the way you'd treat a credit card. Carry it only when you need it, keep it somewhere secure otherwise, and give the number only to providers and people who should have it. Medicare will never call you out of the blue to ask for your Medicare number, so an unsolicited request for it is a red flag, not a routine check.Centers for Medicare & Medicaid Services. (n.d.). Reporting Medicare fraud & abuse. medicare.gov. Retrieved Sep 2, 2026, from https://www.medicare.gov/basics/reporting-medicare-fraud-and-abuse
Watch in particular for a common version of this scam: someone contacts you out of the blue saying you need a "new" or "updated" Medicare card, then asks for your Medicare number, bank account number, or credit card number. Real Medicare cards are free and mailed to you automatically, and Medicare will never tell you to pay for your Medicare card or try to sell you anything. True Medicare representatives won't call, text, or email you out of the blue to ask for your numbers or a payment. Hang up, and give your number only to a provider you trust.U.S. Social Security Administration. (n.d.). How do I get a replacement Medicare card?. ssa.gov.

Frequently Asked Questions
Is there a fee to replace a Medicare card?
No. Real Medicare cards are free, and Medicare will never tell you to pay for one, whether you replace it online, by phone, or through the Railroad Retirement Board.
Can I get a copy without waiting for the mail?
Yes, if you use your secure account at Medicare.gov, which you can create if you don't have one. It lets you print an official copy of your card yourself. Mailed cards take as long as the mail takes; Medicare doesn't publish a delivery window, though the Railroad Retirement Board mails replacements within 30 days.
What is the Medicare number on my card?
It's your Medicare Beneficiary Identifier (MBI), a unique, randomly generated 11-character number that isn't based on your Social Security number. CMS began mailing MBI cards in April 2018, replacing the old Social Security number-based Medicare numbers.
How often can I request a replacement card?
If you're a representative payee requesting a card for someone else, the limit is one replacement card per beneficiary in a 30-day period. No federal page states a comparable cap on requesting your own card. Either way, if you need the number sooner than a mailed card arrives, print a copy from your Medicare.gov account.
What should I do if my Medicare card was stolen?
Replace it, then watch for fraud. Review your Medicare Summary Notices (or your plan's Explanation of Benefits) for services you didn't receive, and report anything suspicious to 1-800-MEDICARE. A stolen Medicare number can be used for medical identity theft.
