Your Medicaid number is on your Medicaid card, in your state's online portal, or available by phone from your state Medicaid office
Your Medicaid number is a unique identifier your state assigns when you are enrolled in Medicaid. It appears on the front or back of your physical Medicaid card, which your state mails to you after approval. If you have not received a card, lost it, or need the number before the card arrives, you can find it through your state's online account portal or by calling your state Medicaid office directly. The number format and card design vary by state — some states print it prominently on the front, others on the back near a barcode.
You will need this number when you see a doctor, fill a prescription, or check on your coverage status. Providers use it to verify your enrollment and submit claims. Having it on hand before your appointment saves time and prevents delays in care.

- If you have not received your card yet, log into your state's Medicaid portal or call your state Medicaid office to get the number by phone.
- The number format differs by state — it may be 10 digits, 12 digits, or include letters, depending on where you live.
- You need your Medicaid number at every doctor visit, pharmacy, and hospital appointment to verify coverage.
Check your state's online Medicaid portal
Most states offer an online account where you can view your Medicaid information without calling. Log in using the username and password you created when you first enrolled, or set up an account if you have not already. Once logged in, look for a section labeled "My Coverage," "Account Information," "My Benefits," or "Enrollment Details" — the exact name depends on your state's system.
Your Medicaid number should appear on the main dashboard or in a summary of your coverage. Some states also show it on a digital version of your card that you can view or download. If you cannot find it online or do not remember your login information, most portals have a "Forgot Password" option or a link to reset your account.
The state portal is often the fastest option because you get the answer immediately without waiting on hold. Write down your number and keep it somewhere safe — in your phone, your wallet, or a document you can access quickly at appointments.
Call your state Medicaid office directly
If you do not have online access or prefer to speak with someone, call your state's Medicaid customer service line. The phone number is on any mail you received from Medicaid, on your Medicaid card if you have it, or on your state's Medicaid website. When you call, have your Social Security number or date of birth ready — the representative will use one of these to look up your account.
Wait times vary by state and time of day. Calling early in the morning or mid-week often means shorter hold times than calling on Monday or Friday afternoon. Tell the representative you need your Medicaid number, and they will read it to you over the phone. Ask them to spell it if it contains letters, and write it down as they say it to avoid errors.
Some states also offer text message or email options to retrieve your number. When you call, ask if your state has these faster alternatives available.
Look at your Medicaid card when it arrives
Your state mails your Medicaid card within one to three weeks after approval, though timing varies. The card is usually plastic and wallet-sized, with your name, date of birth, and Medicaid number printed on it. The number is typically on the front in large print, but some states place it on the back or on a separate line.
Keep your card in a safe place and bring it to every medical appointment. If your card is damaged, lost, or stolen, contact your state Medicaid office to request a replacement. Most states mail a new card within two weeks, but you can still receive care during that time — providers can look up your coverage using your Social Security number or date of birth if you give them your Medicaid number verbally.
Understand what your Medicaid number looks like
Medicaid numbers vary in format by state. Some states use a 10-digit number, others use 12 digits, and some include letters or a combination of both. For example, one state might use all numbers, while another might use a format like "ABC123456789." There is no national standard, so your number will look different from someone else's Medicaid number in another state.
Your number stays the same as long as you remain enrolled in Medicaid in that state. If you move to a different state, you will need to enroll in that state's Medicaid program and will receive a new number. If you move within the same state, your number usually does not change, but contact your state office to confirm your address is current.
What to do if you cannot find your number
If you have searched your online portal, checked your mail, and cannot reach your state office by phone, try these steps: First, check any letters or notices from Medicaid — your number may appear in the body of the letter even if you do not see it on a card. Second, contact your doctor's office or a recent pharmacy — they may have your number on file from a previous visit and can read it back to you. Third, try your state Medicaid website's live chat or email option if your state offers it.
If you are having trouble accessing your state's online portal, look for a "Help" or "Contact Us" link on the portal itself. Many states have a dedicated support team for account access issues. You can also visit your state Medicaid office in person if there is a local office near you — staff can print your number on the spot.
Frequently Asked Questions
Is my Medicaid number the same as my Social Security number?
No. Your Medicaid number is separate from your Social Security number. Providers need your Medicaid number to submit claims to your state's Medicaid program. Your Social Security number is used to verify your identity when you enroll or update your information.
Can I use someone else's Medicaid number if I do not have mine yet?
No. Each Medicaid number belongs to one person only. If you do not have your number yet, tell your provider your name and date of birth, and they can look up your coverage in the system. Do not use another person's number — it can cause billing problems and may be considered fraud.
What if my Medicaid card has the wrong information on it?
Contact your state Medicaid office right away. If your name, date of birth, or address is incorrect, the office will correct it and mail you a new card. In the meantime, tell your provider about the error so they can update their records and process your claims correctly.
Do I need my Medicaid number if I have my physical card?
You should bring your physical card to every appointment, but having the number memorized or written down is helpful in case you forget the card. Providers can look up your coverage using the number alone, so you will not be turned away if you have the number but not the card.
How long does it take to get a Medicaid card after approval?
Most states mail cards within one to three weeks after you are approved for Medicaid. Some states are faster, others slower. You can use your Medicaid coverage as soon as your state approves you, even if your card has not arrived yet — call your state office to get your number in the meantime.
