Key takeaways

  • Medicare will never call, text, or email you out of the blue to ask for your number, so treat that as a red flag.
  • Protect your Medicare card like a credit card, only carrying it when you need it and shredding paperwork that shows your number before tossing it.
  • Check your Medicare Summary Notice or your online Medicare.gov account every month for services, dates, or providers you don't recognize, and keep a simple health calendar to help you compare.
  • If you think you've shared your number with a scammer, act quickly since Medicare can, in some cases, issue you a new Medicare Beneficiary Identifier once fraud is confirmed.

Why Your Medicare Number Matters

Think of your Medicare number the way you think of a credit card. If a thief gets hold of it, they can bill Medicare for services you never received, medical equipment you never ordered, or tests you never took. That fraud drives up costs for everyone, and it can also clutter your medical record with false information that affects your real care later on.

Medicare doesn't call, text, or email you out of the blue to ask for your number. If someone does, that's a red flag — full stop.

Common Scams to Watch For in 2027

The Senior Medicare Patrol (SMP), a federally funded fraud-prevention program, tracks the scams older Americans report most often. In recent months, these have topped the list:

Fontana is in San Bernardino County, where dozens of Medicare Advantage and Part D plans are marketed each fall. That volume of legitimate outreach can make it harder to spot the bad actors — so slow down and verify before you share anything.

Simple Steps to Guard Your Number

1. Treat your Medicare card like a credit card. Carry it only when you need it. 2. Never give your number to anyone who calls, texts, emails, or knocks unannounced. 3. Check your Medicare Summary Notice or your online account at Medicare.gov every month. Look for services, dates, or providers you don't recognize. 4. Keep a simple health calendar. Jot down doctor visits, tests, and equipment deliveries so you can compare later. 5. Shred paperwork with your Medicare number before throwing it out. 6. Hang up on pressure. Real Medicare representatives will never threaten you or rush you.

What to Do If You Think You've Been Targeted

If you shared your Medicare number with someone you now suspect, don't panic — but act quickly:

Medicare can, in some cases, issue a new Medicare Beneficiary Identifier if fraud is confirmed.

Frequently asked questions

Is Medicare sending out new cards for 2027?
No. If someone claims Medicare is issuing chip cards, plastic cards, or updated 2027 cards and asks for your number to "activate" one, it's a scam.
A caller said my benefits will be cut off if I don't confirm my number. Is that real?
No. Medicare does not cancel benefits by phone. Hang up and call 1-800-MEDICARE directly if you're unsure.
Can I give my Medicare number to a plan agent during AEP?
You can share it with a licensed agent you contacted or agreed to meet with — but never with someone who cold-called or showed up uninvited. When in doubt, verify the agent through your SHIP/HICAP office first.
