How to Check Your Medicare Enrollment Status in 2026
Quick answer
You can check your Medicare enrollment status by signing in at medicare.gov or ssa.gov, or by calling 1-800-MEDICARE or Social Security. Your Medicare card shows your coverage start dates.
- Check enrollment in your free Medicare.gov or my Social Security account.
- Confirm which parts (A, B, D) you have and their start dates.
- If you were auto-enrolled, your card comes in the mail.
- Fix any gap during an enrollment period to avoid a lifelong penalty.
Whether you are newly eligible or want to confirm your coverage, checking your Medicare enrollment status takes just a few minutes. Here is how to check your Medicare enrollment status in 2026.
Check online
- MyMedicare at Medicare.gov: log in to see the parts you have (A, B, D), your effective dates, and any plan you are enrolled in.
- my Social Security at ssa.gov: since Social Security handles enrollment, your account shows whether you are signed up for Part A and Part B.
Both accounts are free, and you never pay a third party to check.

Check by phone or mail
- Call Medicare at 1-800-MEDICARE (1-800-633-4227).
- If you were automatically enrolled (because you already get Social Security), your red-white-and-blue Medicare card arrives in the mail about three months before your 65th birthday.
What to confirm
- Part A (hospital) and Part B (medical): are you enrolled, and what are the start dates?
- Part D (drugs) or a Medicare Advantage plan: are you in one, and does it fit your needs?
- Premiums: is your Part B premium being paid, and could a Medicare Savings Program cover it?
Learn how the parts fit together in the Medicare guide and what to bring in the documents needed to apply for Medicare.
Fix a gap before it costs you
If you find you are not enrolled when you should be, act during an enrollment period – the Initial, General, or a Special Enrollment Period – to avoid a lifelong late penalty. If a claim or service was denied, see how to appeal a Medicare denial.

Official ways to check Medicare enrollment (2026)
Social Security handles Medicare Part A and Part B enrollment — not a state agency. Check your status by signing in to your my Social Security account. Phones: SSA 1-800-772-1213 (TTY 1-800-325-0778); 1-800-MEDICARE (1-800-633-4227) for Part C, Part D, and card questions.
What each status means: received / in process = SSA is reviewing; approved = your Medicare card is on the way; action needed = SSA mailed a request for information. If you applied online, note your confirmation number and watch for an award letter or a request-for-evidence letter by mail.
