Recently, some Medicare beneficiaries have heard that new Medicare card numbers are being issued in 2026. Many people are wondering whether this affects them. Here is what you should know.

Are Medicare Card Numbers Changing This Year

Yes, but only for a small number of people. The Centers for Medicare & Medicaid Services is mailing new Medicare card numbers to certain beneficiaries as part of a security update related to fraud prevention. If you are affected, your new card will arrive automatically by mail. You do not need to request one.

NOTE: Most Medicare beneficiaries will not receive a new number.

Why Some Medicare Numbers Are Being Replaced

From time to time, the Centers for Medicare and Medicaid Services updates Medicare identification numbers for certain beneficiaries as part of ongoing efforts to protect personal information and reduce fraud. If your number is affected, Medicare automatically sends a replacement card by mail and no action is required from you.

What Should You Do If You Receive a New Medicare Card

If you receive a new Medicare card in the mail, you should do the following:

• Start using the new number immediately
• Safely destroy your old card
• Share your new number with your doctors if needed
• Let your insurance agent know so your records stay updated

There is no cost for a replacement Medicare card. If your Medicare card is lost or damaged, you can request a replacement card at any time through your secure account at Medicare.gov or by calling (800) MEDICARE. Replacement cards are mailed directly from Medicare and there is never a fee for this service.

Important Fraud Warning

Unfortunately, scammers often take advantage of situations like this.

Please remember that Medicare will never do any of the following:

• Call you unexpectedly to ask for your Medicare number
• Charge you for a replacement card
• Ask for banking information to send a new card
• Threaten that your coverage will be cancelled unless you respond immediately
• Send plastic or chip Medicare cards

IMPORTANT: If someone contacts you and asks for personal information related to your Medicare card, it is very likely a scam.

How To Recognize An Official Medicare Mailing

An official Medicare mailing does the following:

• Arrives by postal mail
• Does not request payment
• Does not ask for banking information
• Includes your name exactly as shown on your Medicare card
• Does not require immediate action to keep your coverage active

If something feels urgent or requests personal information, it is best to verify it before responding.

What Should You Do If You Receive a Suspicious Call

If you receive a suspicious call about Medicare, the safest step is to contact Medicare directly at (800) MEDICARE to confirm whether the request is legitimate. You are also welcome to contact me if you would like help reviewing anything you receive.

About the Author

I’m an independent Medicare Supplement insurance specialist working with most of the major insurance carriers throughout California, Nevada, and several other states. I help people turning 65 coordinate their Medicare enrollment so their Medicare Supplement and prescription drug coverage begin at the same time as Medicare.

I also work with many people who already have Medicare Supplement plans and would like to review their options. In California, the Medicare Supplement Birthday Rule allows policyholders to change their plans each year without medical underwriting, and I regularly help clients lower their premiums while keeping the same identical plan and coverage. Many of my clients have saved hundreds, and sometimes thousands, of dollars.

There is no charge for my services because I am compensated by the insurance carriers, not my clients. My goal is to help you find competitive premiums and provide dependable personal service year after year.

If you are turning 65 soon, or if you already have a Medicare Supplement plan and would like to review your options, I am happy to help.
