If you’ve recently realized you have a lost Medicare card, you’re not alone. Every year, thousands of Americans misplace or damage their red, white, and blue Medicare cards. Thankfully, replacing it in 2026 is simple, free, and faster than ever with the latest online and mobile options available through the Social Security Administration (SSA) and Medicare.gov.
This guide walks you through every step to get a new card, what to do if someone steals your information, and how to protect your Medicare number in the future.

What Your Medicare Card Does
Your Medicare card is more than a piece of plastic — it’s your official proof of health insurance under the U.S. federal Medicare program. It contains:
- Your name
- Your Medicare Number (a unique, non-Social Security-based identifier)
- The type of coverage you have (Part A, Part B, and sometimes Part D)
- The date your coverage started
You need this card whenever you visit doctors, hospitals, or pharmacies that accept Medicare. Losing it doesn’t mean your coverage stops — it only means you’ll need to request a new physical or digital copy for verification.
What to Do if You Lost Your Medicare Card
If your Medicare card is lost, stolen, or damaged, there are three primary ways to replace it in 2026:
1. Request a Replacement Online (Fastest Method)
The quickest and most secure way to replace a lost Medicare card is through the official Social Security website or Medicare.gov.
Steps:
- Go to SSA.gov/myaccount and sign in to your my Social Security account.
- Select “Replace your Medicare card.”
- Confirm your mailing address is correct.
- Submit your request — your new card will arrive within two weeks.
If you prefer, you can also use Medicare.gov to print a copy of your card immediately. Log in to your MyMedicare account and download a digital version you can save or print for future use.
2. Call Social Security for Assistance
If you cannot access your account online, you can request a replacement by phone.
- Toll-free number: 1-800-772-1213
- TTY: 1-800-325-0778
- Hours: Monday through Friday, 8 a.m. – 7 p.m. local time
A Social Security representative will verify your identity and mail a new card to the address they have on file.
3. Visit a Local Social Security Office
For in-person support, you can visit a Social Security Administration office near you. You’ll need a valid form of identification such as:
- A U.S. driver’s license
- A state-issued ID card
- A U.S. passport
Appointments aren’t required but are highly recommended to reduce waiting times.
Replacing a Lost Medicare Advantage or Drug Plan Card
If you’re enrolled in a Medicare Advantage (Part C) plan or a Medicare Prescription Drug (Part D) plan, your plan provider issues its own card — separate from your federal Medicare card.
If that card is lost:
- Contact your insurance company directly using the member services number on any statements or emails you receive.
- Most plans allow you to order a replacement online through your member portal.
- A new card typically arrives within 7–10 business days.
Keep in mind: You’ll still need your original red, white, and blue Medicare card for certain services, even if you use a Medicare Advantage plan.
How Long It Takes to Get a New Medicare Card
Once your replacement is requested, it generally takes about 14 calendar days to arrive by mail. In some areas, delivery may take slightly longer due to postal delays.
If you need proof of Medicare coverage sooner, log in to MyMedicare.gov and print a temporary copy. Healthcare providers can also verify your enrollment electronically through Medicare’s secure database.
What to Do if Your Medicare Card Was Stolen
If you suspect your Medicare card was stolen, take these steps immediately to protect your personal information:
- Call Medicare at 1-800-MEDICARE (1-800-633-4227).
- Explain the situation and request a new card with a different Medicare Number.
- Check your Medicare Summary Notices (MSNs).
- Review all charges for services or supplies you didn’t receive.
- Report suspected fraud to the Office of Inspector General (OIG) at 1-800-HHS-TIPS (1-800-447-8477).
- Notify your healthcare providers.
- Let them know your old Medicare number was compromised so they can update their records.
Replacing a stolen card automatically invalidates the old number, preventing anyone from using it for false claims or medical identity theft.
Using a Digital Medicare Card
In 2026, Medicare continues to expand digital access options for beneficiaries. Through your MyMedicare.gov account, you can now:
- View your card online anytime
- Print a paper version on demand
- Show your digital card on your smartphone or tablet at appointments
This makes it easier to access your information securely without waiting for mail delivery. It’s a convenient option for travelers, caregivers, or anyone who frequently misplaces physical cards.
Common Reasons People Lose Their Medicare Card
Misplacing a Medicare card can happen for many reasons — and it’s often accidental. Here are the most frequent causes reported by beneficiaries:
- Moving homes and losing important documents during packing
- Forgetting the card in hospital check-in areas or pharmacies
- Wallet or purse theft
- Damage from water, wear, or washing machines
- Misplacing paperwork when traveling
For peace of mind, it’s best to keep a photocopy or digital backup in a safe but easily accessible place.
How to Protect Your Medicare Number
Your Medicare Number is unique to you and should be treated like a Social Security Number. Identity theft and medical fraud cases have increased nationwide, making it vital to keep your card secure.
Here’s how to protect it:
- Never give your Medicare Number over the phone unless you initiated the call.
- Don’t carry your card unless you need it for an appointment.
- Shred old documents containing your Medicare information.
- Review your Medicare Summary Notices (MSNs) every month.
- Report suspicious billing immediately.
You can also sign up for Medicare’s electronic alerts, which notify you about claims or unusual activity linked to your number.
How to Get a Replacement for Someone You Help
If you’re a caregiver, spouse, or legal representative, you can request a replacement card for someone else under certain conditions.
You must have one of the following:
- Authorized Representative status on file with Social Security
- A Power of Attorney document recognized by the SSA
- Access to the beneficiary’s MyMedicare or my Social Security account
Once verified, you can request and manage Medicare replacements just as the beneficiary would.
Special Cases: New Medicare Cards for 2026
Medicare occasionally issues new cards automatically when a person’s coverage changes — for instance, when:
- You enroll in Medicare Part B after having only Part A
- You switch from Medicare Advantage back to Original Medicare
- You update your legal name or address
If any of these apply, your new card will be mailed automatically and typically arrives within 30 days of the change.
