You can change your Medicare address online, by phone, or by mail

Medicare keeps your address on file so it can send you bills, notices about coverage changes, and other important documents. If you move, you need to update that address with Medicare — not with Social Security or your doctor's office, though you may need to update those separately. The fastest way is online through your Medicare account. If you do not have an online account or prefer to call, Medicare's phone line can process the change while you wait.

You will need your Medicare number, which is on your Medicare card. The change usually takes effect within a few days, though mail sent to your old address may still arrive for a week or two after you update it.

Key Takeaways

  • You can change your address online at Medicare.gov, by calling 1-800-MEDICARE (1-800-633-4227), or by mailing a form to your local Social Security office.
  • Your Medicare number is the only information you must have ready; you do not need your Social Security number or a password if you call.
  • The address change takes effect within a few days, but mail in transit may still arrive at your old address for up to two weeks.
  • If you have a Medicare Advantage or Part D plan through a private insurance company, you may also need to notify that company directly.
  • Update your address with your doctor's office, pharmacy, and any other healthcare providers separately — Medicare does not share address changes with them.

Changing your address online through Medicare.gov

Go to Medicare.gov and sign in to your account. If you do not have an account, you can create one using your email address and Medicare number. Once you are signed in, look for "Personal Information" or "My Health Information" in the account menu — the exact wording varies depending on which version of the site you see.

Select the option to edit your address. Enter your new street address, city, state, and ZIP code. Medicare will ask you to confirm the address before saving it. Once you submit, you should see a confirmation message on screen. The change is usually live within 24 hours.

If you run into trouble creating an account or signing in, call 1-800-MEDICARE and a representative can walk you through it or make the change for you over the phone.

Changing your address by phone

Call 1-800-MEDICARE (1-800-633-4227). The line is open Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday, 9 a.m. to 1 p.m. Eastern time. Have your Medicare number ready. You do not need your Social Security number or any password.

Tell the representative that you have moved and give them your new address. They will read it back to you to confirm it is correct. The change takes effect when ready in Medicare's system, though you may receive mail at your old address for a few days afterward if it was already in the mail queue.

If you are deaf or hard of hearing, call 1-877-486-2048 (TTY). If you speak a language other than English, Medicare can provide an interpreter at no cost — just tell the representative when you call.

Changing your address by mail

You can also submit a change-of-address form to your local Social Security office. read the form from the Social Security website or pick one up in person. Fill in your Medicare number, new address, and sign the form. Mail it to the Social Security office that serves your area — you can find the address on the Social Security website by entering your ZIP code.

This method is slower than calling or using the website. It typically takes two to three weeks for the change to show up in Medicare's records. Use this route only if you cannot access the phone line or the website.

Notifying your Medicare Advantage or Part D plan

If you have a Medicare Advantage plan or a separate Part D prescription drug plan through a private insurance company, you should also notify that company directly. Call the customer service number on your insurance card and tell them you have moved. They need your new address for their own records and to make sure they can reach you about plan changes or claims.

Some insurance companies update automatically when Medicare updates, but many do not. It is safer to call them yourself and confirm the change went through. Ask them to send you a confirmation letter with your new address on file.

Updating your address with doctors and pharmacies

Medicare does not share address changes with your healthcare providers. You need to call your doctor's office, dentist, eye doctor, and any other providers you see regularly and give them your new address. Do the same with your pharmacy — they use your address to mail prescriptions and send refill reminders.

If you use mail-order pharmacy services, update your address with them as well. Some mail-order pharmacies are part of your Medicare Part D plan, so they may already have your new address if you notified the plan, but it is worth confirming with them directly.

What to do if you move before your Medicare card arrives

If you have just enrolled in Medicare and you move before your card arrives in the mail, update your address with Medicare before the card ships. Call 1-800-MEDICARE and give them your new address. Tell them you are a new beneficiary and have not yet received your card. They can make sure the card is mailed to your new address.

If your card has already been mailed to your old address, you can request a replacement card once you have updated your address. The replacement usually arrives within two weeks. In the meantime, you can use your Medicare number (which you should have from your enrollment confirmation) to show you have coverage.

Frequently Asked Questions

Do I need to update my address with Social Security if I change my Medicare address?

No. Medicare and Social Security keep separate address records. If you receive Social Security benefits, you should update your address with Social Security as well, but doing one does not automatically update the other. You can change your Social Security address by calling 1-800-772-1213 or visiting your local Social Security office.

How long does it take for Medicare to process an address change?

If you change your address online or by phone, it usually takes effect within 24 hours. If you mail a form, allow two to three weeks. Mail that was already sent to your old address may still arrive for up to two weeks after the change, so do not be alarmed if you receive a Medicare notice at your old address shortly after moving.

What if I move to a different state?

Update your address the same way you would for a move within your state. However, if you have a Medicare Advantage or Part D plan, check whether that plan is available in your new state. Some plans do not cover all states. If your plan does not serve your new location, you will need to switch plans during the Annual Enrollment Period or within 60 days of moving, whichever gives you more time.

Can I change my address on my Medicare card itself?

No. Your Medicare card is issued by the federal government and cannot be marked up or altered. Once you update your address with Medicare, your next card replacement will have the new address printed on it. You do not need a new card to use your coverage — your Medicare number stays the same.

What if I am in a nursing home or assisted living facility?

Update your address to the facility's address. If you are there temporarily, you can update it again when you leave. If the facility has a business office or social worker, they can often help you make the change or do it for you — just ask. Make sure Medicare has the correct address so important notices reach you or your family.
