Where to find your Medicare number when you don't have the card

Your Medicare number is printed on your card, but you can find it without one by calling Medicare directly, checking documents from Social Security or your doctor's office, or logging into your online Medicare account. The fastest route is usually a phone call to Medicare, which takes about 10 minutes and requires only your name and date of birth.

Medicare keeps your number on file permanently, so it does not matter how long ago you received your card or whether you have lost it. The number itself never changes — it is tied to your Social Security number for life.

Calling Medicare directly for your number

The simplest way to find your Medicare number is to call 1-800-MEDICARE (1-800-633-4227). Have your name, date of birth, and Social Security number ready. A representative will confirm your identity and read your Medicare number to you. The call usually takes 10 to 15 minutes, and you can write the number down while they read it.

Medicare's phone lines are open Monday through Friday from 8 a.m. to 8 p.m. Eastern time. If you call outside those hours, you can leave a message and someone will call you back the next business day. If you are deaf or hard of hearing, call 1-877-486-2048 (TTY).

Checking medical records and bills from your doctor

Any paperwork your doctor's office gave you after you enrolled in Medicare will have your number on it. Look for appointment confirmation letters, billing statements, explanation of benefits forms, or insurance cards they may have printed for you. These documents typically show your Medicare number in the upper right corner or in a patient information section.

If you have had a hospital stay or surgery since turning 65, the bill or discharge paperwork will show your Medicare number. You can call your doctor's billing department directly and ask them to read your number to you over the phone — they have it in their system and can verify your identity with your date of birth and address.

Using your Social Security account to find your number

If you have a my Social Security account, you can log in at ssa.gov and view your Medicare information. Click "View your Social Security Statement" and look for the Medicare section, which shows your Medicare number. If you do not have an account yet, you can create one for free using your email address, phone number, and Social Security number.

Creating a my Social Security account takes about 10 minutes. You will need to verify your identity by answering questions about your financial history. Once your account is set up, you can view your Medicare number anytime without calling.

Creating a Medicare.gov account to see your information online

You can create an account on Medicare.gov even if you have never logged in before. Go to Medicare.gov, click "Sign In" in the upper right, and select "Create an account." You will need your email address, a password, and your Social Security number. Medicare will send you a verification code by email to confirm your identity.

Once you are logged in, your Medicare number appears on your home page under "Your Medicare Information." You can also see your coverage details, claims history, and prescription drug coverage from this account. This method works whether or not you have your card.

What to do if you cannot verify your identity

If you are having trouble creating an online account or verifying your identity by phone, you can visit a local Social Security office in person. Bring a photo ID and your Social Security card if you have it. A representative can confirm your Medicare number and print it for you on the spot.

You can find your nearest Social Security office by going to ssa.gov/locator or calling 1-800-772-1213. Wait times at offices vary, so calling ahead to ask about current wait times can help you plan your visit.

Keeping your Medicare number safe once you find it

Your Medicare number is sensitive information — it is linked to your health records and can be used to commit fraud. Once you locate your number, write it down and store it somewhere safe, like a locked drawer or a password-protected document on your computer. Do not carry it in your wallet or share it over email unless you initiated the contact.

If you suspect someone has used your Medicare number fraudulently, call Medicare at 1-800-MEDICARE right away. You can also report fraud to the Office of Inspector General at 1-800-HHS-TIPS (1-800-447-8477).
