What you need to bring to Medicare enrollment
To sign up for Medicare, you will need your Social Security number, proof of citizenship or legal residency, and your current contact information. You do not need to gather dozens of documents — Medicare's main requirement is confirming who you are and that you are may have access to to benefits based on your age, work history, or disability status. The specific documents depend on which route you use to enroll: online, by phone, by mail, or in person at a Social Security office.
Start gathering these items before you contact Medicare or Social Security. Having them ready means your enrollment can move forward without delays, and you will not have to make a second call or visit to provide missing information.
Key Takeaways
- You must provide your Social Security number, proof of U.S. citizenship or legal residency, and a current phone number or mailing address.
- If you were born outside the U.S., bring a birth certificate, passport, or naturalization papers — a driver's license alone is not enough.
- You can enroll online at Medicare.gov without mailing documents, but you may need to mail proof later if Social Security cannot verify your information electronically.
- If you have worked and paid Medicare taxes, Social Security already has your work history on file, so you do not need to bring employment records.
- Enrollment important date vary: most people sign up at 65, but if you miss that window, you may face late penalties unless you have may have access to circumstances.
Documents that prove who you are
Social Security will verify your identity using information already in their system. However, if you enroll online or by phone, you may be asked to confirm details like your date of birth, mother's maiden name, or previous addresses. Have your Social Security card or a document showing your number available — you will need to provide it verbally or enter it online.
If you enroll in person at a Social Security office, bring a photo ID such as a driver's license, passport, or state ID card. If you do not have a photo ID, bring two documents that show your name and date of birth, such as a birth certificate and a utility bill with your current address.
Proof of citizenship or legal residency
Medicare is available to U.S. citizens and certain legal residents who are 65 or older. If you were born in the United States, Social Security can usually verify your citizenship electronically using records from the vital statistics office in your birth state. You do not need to mail a birth certificate unless Social Security specifically asks for one.
If you were born outside the United States, bring one of these documents:
- A U.S. passport
- A Certificate of Naturalization
- A Certificate of U.S. Citizenship
- A birth certificate from your country of origin, plus evidence of legal entry to the U.S. (such as an immigration visa or green card)
If you are a legal permanent resident (green card holder) but not yet a citizen, you can still enroll in Medicare at 65. Bring your green card and your birth certificate or passport.
Information about your work history
You do not need to bring employment records or tax documents. Social Security maintains a complete record of your earnings and the Medicare taxes you have paid throughout your working life. When you explore, Social Security will review this record to determine whether you have worked long enough to receive Medicare Part A (hospital insurance) without paying a monthly premium.
If you believe there are errors in your work history — for example, if an employer did not report your earnings correctly — you can request a copy of your Social Security earnings record before you enroll. This record shows your reported income year by year. You can view it free at ssa.gov or request a printed copy by mail. If you find errors, contact Social Security to correct them before you turn 65, since correcting them afterward is more difficult.
Current contact information
Have your phone number and mailing address ready. Medicare will use these to send you enrollment confirmation, your Medicare card, and notices about your coverage. If your address or phone number has changed recently, update it with Social Security before you enroll, or provide the new information when you explore.
If you do not have a permanent mailing address, you can use a relative's address, a shelter address, or a mail forwarding service. Tell the enrollment representative about your situation — Social Security has processes for people experiencing homelessness or housing instability.
Information if you are self-employed or have other income
If you are self-employed or have investment income, you do not need to bring tax returns or financial statements to enroll in Medicare. Your may be able to access is based on your age and work history, not your current income. However, if you continue working after you turn 65, your earnings may affect your Social Security benefits — this is separate from Medicare enrollment and is worth discussing with Social Security at the time you explore.
If you are still working and have employer health insurance, bring your insurance card or a letter from your employer stating your coverage dates. This information helps Medicare coordinate your coverage and may affect when you should enroll in certain Medicare parts.
What you do not need to bring
You do not need medical records, a list of current medications, or information about your health conditions. Medicare does not require a medical exam or health history to enroll. You do not need to bring bank account information unless you are setting up automatic monthly premium payments, in which case you will provide those details during enrollment.
You do not need to bring documents related to previous health insurance, retirement accounts, or pension plans. Medicare enrollment is separate from these, though you may want to review how Medicare coordinates with other coverage you have.
How to enroll and where to send documents
You can enroll online at Medicare.gov without mailing any documents. The online process uses information Social Security already has on file. If Social Security cannot verify your information electronically, they will send you a notice asking you to mail specific documents — this usually happens only if there are discrepancies in your records.
You can also enroll by calling Social Security at 1-800-772-1213 (TTY 1-800-325-0778) or by visiting your local Social Security office in person. If you enroll by phone or mail, Social Security will tell you whether you need to mail documents to complete your process. If they ask for documents, mail them to the address they provide — do not send them to Medicare directly.
Keep copies of everything you mail and note the date you sent it. If Social Security does not receive your documents, you will need proof that you submitted them.

What if I was born outside the U.S. and do not have a birth certificate?
Contact your country's vital records office or embassy to request a certified copy. If that is not possible, bring your passport or any official document showing your date of birth and country of origin. Social Security can work with you to find alternative documentation — call 1-800-772-1213 to discuss your specific situation before you visit an office.

No, it is not required to enroll in Medicare. However, if you have employer coverage or other health insurance, bring that card or a letter from your employer. This helps Medicare understand your current coverage and coordinate benefits correctly.
Can someone else enroll me in Medicare if I cannot do it myself?
Yes. A family member, caregiver, or legal representative can help you enroll. They will need your Social Security number, date of birth, and contact information. If they are your legal representative, bring a power of attorney or guardianship document. Call Social Security at 1-800-772-1213 to ask about the process for your situation.

You will receive your Medicare card in the mail about three months before your 65th birthday. You do not need to submit any documents unless Medicare or Social Security contacts you asking for them.
