Every fall, mailboxes fill up with Medicare plan letters. Some doorbells ring too. Medicare’s annual Open Enrollment Period runs from October 15 to December 7, and it is the busiest season of the year for Medicare scams.
Most of that mail is real. Most visitors who ring your bell are neighbors or delivery drivers. But a small number of letters and knocks are scammers dressed up as Medicare, and they know exactly which weeks to strike.
This guide covers the two scam styles that show up most during open enrollment: mail that looks official and people who show up in person calling themselves Medicare agents. If you are looking for the phone call version of this scam instead, see our guide to Medicare scam calls.
Is That Medicare Agent at My Door Real?
No, Medicare itself never sends anyone to your door uninvited. Medicare.gov says this directly: Medicare will never call you to sell you anything or visit you at your home. The only time a licensed agent should be at your door is if you personally scheduled that appointment.
That means anyone who knocks and says “I’m here about your Medicare benefits” or “I need to update your Medicare card” without you inviting them is not a real Medicare representative. They may be a licensed insurance agent breaking the rules, or they may not be an agent at all.
Plain talk: Open Enrollment Period
This is the yearly window, October 15 to December 7, when people with Medicare can join, drop, or switch a Medicare Advantage or drug plan for the following year. Coverage starts January 1.
How Mail Scams Work During Open Enrollment
Scam mail is designed to look like it came from Medicare, the Social Security Administration, or a well known insurance brand. Common tricks include:
- An official looking seal, an eagle, or wording like “Time-sensitive Medicare notice”
- A deadline of 24 to 48 hours to “avoid losing coverage”
- A request to call a phone number printed in the letter to “confirm your Medicare number”
- A form asking you to mail back your Medicare number, date of birth, or bank details to “activate” a new card or benefit
- A claim that you qualify for a free item (a brace, a genetic test kit, groceries, or utility help) if you just provide your Medicare number
Real Medicare mail never asks you to call a number in the letter to “verify” your Medicare number. Genuine plan mail also gives you weeks, not hours, to decide.
Try this
Before responding to any Medicare letter, flip it over. Look for the sender’s return address. If it does not clearly match Medicare.gov, the Social Security Administration, or your actual current plan, set it aside and call 1-800-MEDICARE to ask if it is real.
Door-to-Door “Agents”: What the Rules Actually Say
Licensed agents do sell Medicare Advantage and Part D plans, and some do knock on doors during open enrollment. But there are limits. An agent is not supposed to show up unannounced and start a sales pitch on your doorstep without your prior invitation or a scheduled appointment.
Warning signs that a door-to-door visitor is not on the level:
- They cannot produce a photo ID and a printed agent or National Producer Number
- They pressure you to sign something the same day
- They ask to see your Medicare card, Social Security card, or bank statements “just to check”
- They tell you your current plan is being cancelled and you must switch today
- They only accept a decision made right there, with no time to think it over or call anyone
Safety tip
Never let a stranger into your home to discuss Medicare, even if they have a lanyard, a clipboard, or a company shirt. You can talk on the porch with the door mostly closed, or simply say you are not interested and close the door. You are never rude for protecting yourself.
Fake Plan Comparison Pitches
Another version of this scam shows up as a “free Medicare plan comparison” offered by mail, at a community event, or from someone who knocks with a folder of plan brochures. The pitch sounds helpful: they will compare your current coverage to something “better” for free.
The problem is what happens next. A fake comparison often ends with pressure to switch on the spot, a request for your Medicare number to “check eligibility,” or a signature on a form you did not get to read carefully. Some victims later find they were enrolled in a plan they never agreed to, or that their doctor is not covered by the new plan at all.
A real plan comparison, done through the official Medicare Plan Finder at Medicare.gov or through a SHIP counselor, never requires an instant decision and never charges a fee.
How to Verify a Real Medicare Representative
Follow these steps any time someone contacts you about Medicare, by mail, at your door, or in person at an event.
- Do not hand over your Medicare number, Social Security number, or bank details on the spot. A real agent does not need those to explain a plan.
- Ask for identification. A licensed agent should show a photo ID and be able to tell you which insurance company they represent.
- Write down the details. Company name, plan name, agent name, and any phone number they gave you.
- Call 1-800-MEDICARE (1-800-633-4227) yourself, using the number on your Medicare card, and ask if the agent, plan, or letter is legitimate.
- Call your local SHIP counselor through shiphelp.org for free, unbiased help comparing any offer before you agree to anything.
- If you already have a plan, call the number on the back of your current Medicare card to confirm your coverage has not changed without your knowledge.
Say this
“I don’t discuss my Medicare number with anyone who contacts me first. If this is real, I can call 1-800-MEDICARE myself to confirm it.”
Real Medicare Contact vs a Scam
| What Medicare or a real agent does | What a scammer does |
|---|---|
| Only visits or calls if you scheduled it | Shows up or calls out of nowhere |
| Gives you weeks to decide, not hours | Demands a decision today |
| Never asks for your Medicare number to “verify” you | Asks for your Medicare number right away |
| Can be confirmed by calling 1-800-MEDICARE | Discourages you from calling anyone else first |
| Never charges a fee to compare or enroll in plans | May ask for a “processing” or “lock-in” fee |
If You Already Gave Out Information
Mistakes happen, and acting fast matters more than feeling embarrassed.
- Call 1-800-MEDICARE and tell them you may have shared your Medicare number with a scammer.
- If you shared a Social Security number or bank details, follow the steps in our guide on how to freeze your credit after a scam.
- Report the scam using our guide to where to report a scam, which covers the FTC and other agencies.
- Tell your local Senior Medicare Patrol at 877-808-2468. They specialize in exactly this kind of fraud and can help you watch your Medicare statements for suspicious claims afterward.
None of this means you did something foolish. These scams are built by people who study Medicare’s real rules closely enough to imitate them convincingly. Our Scam-Stopper Kit (free when you join our email letter) walks through a short checklist for moments like this, so you have it ready before you need it.
Mail and Door Scams vs Phone Call Scams
This guide focuses on paper and in-person tactics because they rely on different tricks than a phone call. A caller can fake a phone number to look local or claim to be returning your call. A letter relies on official-looking design, and a doorstep visit relies on the pressure of a real person standing in front of you. If a call is the version you are dealing with right now, our guide to Medicare scam calls walks through those specific red flags and scripts.
Whichever form it takes, the underlying rule stays the same. Medicare itself does not initiate contact to sell you something, by mail, by phone, or at your door. When something arrives asking you to act fast and share your Medicare number, slow down and verify it yourself first.
Where to go from here
Open enrollment scams work by rushing you. Slowing down, even by one phone call to 1-800-MEDICARE or your local SHIP counselor, is usually enough to stop them cold. For more ways to spot pressure tactics and protect your information across every kind of scam, our book Scam-Proof walks through these situations in plain, large-print steps.
