Your Medicare number is on your red, white, and blue Medicare card
Your Medicare number is a unique identifier that Medicare uses to track your account and process your claims. It appears on the front of your Medicare card, which is a physical card about the size of a credit card that you receive when you first enroll in Medicare. The number itself is 11 characters long — usually a mix of numbers and letters — and it stays with you as long as you have Medicare coverage.
You will need this number whenever you see a doctor, fill a prescription, or have any interaction with Medicare. Your healthcare providers use it to verify your coverage and submit claims on your behalf. Insurance companies and pharmacies also ask for it regularly, so knowing where to find it quickly saves time at appointments.

Locating the number on your Medicare card
Open your Medicare card and look at the front. Your Medicare number is printed in the upper right corner, just below your name. It is the 11-character code that begins with your Social Security number (the first nine digits) followed by a letter and then one more digit. The card also shows your coverage type — whether you have Original Medicare, a Medicare Advantage plan, or another type of coverage — and the date your coverage began.
The back of the card lists the phone numbers you should call if you have questions about your coverage. If your card is damaged, faded, or lost, you can request a replacement card from Medicare at no cost. The new card will have the same Medicare number printed on it.
Checking your number online at Medicare.gov
If you do not have your card in front of you, you can view your Medicare number on the official Medicare website. Go to Medicare.gov and click "Log In" in the upper right corner. You will need to create an account using your email address and a password, or you can log in with your existing account if you have already set one up.
Once you are logged in, your Medicare number will appear on your account dashboard under "My Medicare." You can view it, print it, or take a screenshot for your records. This method works at any time of day and does not require you to wait on hold with a representative.
Calling Medicare directly for your number
You can also reach Medicare by phone to find out your number. Call 1-800-MEDICARE (1-800-633-4227). The line is open Monday through Friday from 8 a.m. to 8 p.m. Eastern Time, and on Saturday from 8 a.m. to 4 p.m. Eastern Time. A representative will ask you to verify your identity by providing your name, date of birth, and Social Security number, then they will read your Medicare number to you.
If you are deaf or hard of hearing, you can use the TTY number 1-877-486-2048. If you speak a language other than English, Medicare offers interpretation services at no cost — just tell the representative which language you speak.
What to do if you have lost your card
If your Medicare card is lost or stolen, you can request a replacement through Medicare.gov or by calling 1-800-MEDICARE. A new card will be mailed to the address Medicare has on file for you, usually within 7 to 10 business days. You do not need to wait for the new card to arrive to use your Medicare coverage — your number remains the same, and you can provide it to your doctor or pharmacy even if you do not have the physical card with you.
If you suspect your Medicare number has been used fraudulently, contact Medicare when ready at 1-800-MEDICARE and report the suspicious activity. You can also file a report with the Office of Inspector General at oig.hhs.gov or call 1-800-HHS-TIPS (1-800-447-8477).
Keeping your Medicare number find
Your Medicare number is sensitive information and should be treated like your Social Security number. Do not share it with anyone who calls you unsolicited, even if they claim to be from Medicare or your insurance company. Medicare will never call you out of the blue asking for your number or personal information.
When you need to provide your Medicare number, make sure you are communicating with a legitimate healthcare provider, pharmacy, or official Medicare representative. If you are unsure whether a caller is legitimate, hang up and call the phone number on your Medicare card or go directly to Medicare.gov to verify.
