# How to Apply for Medicare: Online, by Phone, or In Person

Applying for Medicare is simpler than most people expect, but the right approach depends on your situation—whether you're already collecting Social Security, whether you want to enroll automatically or actively, and whether you're signing up for Part A only or both Part A and Part B. This guide walks you through every application method and helps you know what to bring and what to expect.

Do You Need to Apply at All?

Some people are enrolled in Medicare automatically. If you're already receiving Social Security retirement benefits or Railroad Retirement Board benefits when you turn 65, Medicare will generally enroll you in Part A and Part B automatically. You should receive your Medicare card in the mail about three months before your 65th birthday.

If you don't want Part B at that time—because you have employer coverage through active employment—you can return the card with written instructions to opt out of Part B. But make sure you have qualifying coverage before doing so, because dropping Part B without a valid reason can lead to a late enrollment penalty later.

If you're not yet receiving Social Security when you turn 65, you will need to apply actively. The same is true if you're enrolling in Medicare under 65 due to disability and you haven't been automatically enrolled after your 24-month SSDI waiting period.

How to Apply Online

Applying online is the most convenient option for most people. The Social Security Administration handles Medicare enrollment, and you can apply at ssa.gov/medicare. The online application typically takes 10 to 30 minutes to complete.

When applying online, you'll be able to:

• Apply for Part A only, Part B only, or both at the same time.
• Choose whether you want Medicare to start immediately or at a later date.
• Submit your application without needing to visit an office or mail any forms.

You don't need to create a my Social Security account to apply—though having one makes it easier to track your application status afterward. You'll receive a confirmation number when your application is submitted, and Social Security will contact you if additional documentation is needed.

How to Apply by Phone or In Person

By phone: Call the Social Security Administration at 1-800-772-1213 (TTY: 1-800-325-0778), Monday through Friday. A representative can complete the application with you over the phone or schedule a callback appointment if wait times are long. Phone enrollment works well if you have questions you'd like answered while applying, or if you're not comfortable with online forms.

In person: You can visit any local Social Security Administration office to apply in person. Find your nearest office at ssa.gov/locator. In-person visits are particularly useful if you're applying under a Special Enrollment Period and need to bring documentation—for example, proof that you had employer coverage that is now ending. Bringing the right paperwork the first time can prevent delays.

Documents that are commonly useful when applying:

• Your Social Security card or number
• Proof of U.S. citizenship or legal residency if you were born outside the U.S.
• If enrolling under an SEP: a letter from your employer confirming your coverage dates, or other documentation of your qualifying event
• Your most recent W-2 or tax return (if applying for Part A based on a spouse's work record)

What Happens After You Apply

After your application is submitted, Social Security processes it and notifies you of your enrollment dates. You'll receive a red, white, and blue Medicare card by mail showing your Medicare number and the effective dates of your Part A and Part B coverage. This card replaces the old Social Security number-based cards and is unique to Medicare.

Once your coverage begins:

• You can use your Medicare card at any doctor, hospital, or provider that accepts Medicare.
• You'll begin receiving your Part B premium bills if you're not yet collecting Social Security—or see the deduction on your Social Security payment if you are.
• You can use mymedicare.gov to review your claims, set up electronic billing, and manage your coverage information.
• If you want additional coverage—like a Medicare Supplement (Medigap) policy, a Medicare Advantage plan, or a Part D drug plan—those enrollments are separate and typically have their own windows tied to when your Part B begins.

One important note: applying for Part A and Part B is just the starting point. Original Medicare has gaps in coverage, including a 20% coinsurance for most Part B services with no out-of-pocket maximum. Most people add a supplement or choose Medicare Advantage to manage those gaps—so think of your Medicare application as the first step in a broader coverage decision.

Frequently Asked Questions

Q: How far in advance should I apply for Medicare? A: Social Security recommends applying up to three months before you want your coverage to start. Since your Initial Enrollment Period begins three months before the month you turn 65, applying early in that window gives you the best chance of having coverage ready on your 65th birthday. Late applications can delay your start date.

Q: Can I apply for Medicare without applying for Social Security retirement benefits at the same time? A: Yes. You can enroll in Medicare independently of Social Security retirement benefits. Many people choose to delay Social Security to increase their monthly benefit, while enrolling in Medicare at 65 to avoid Part B late enrollment penalties. The Social Security Administration handles both, but they are separate decisions.

Q: What if I applied and never received my Medicare card? A: If your Medicare card doesn't arrive within a few weeks of your expected coverage start date, contact Social Security at 1-800-772-1213 or log into your my Social Security account to check your enrollment status. You can also request a replacement card through mymedicare.gov or by calling 1-800-MEDICARE (1-800-633-4227).
