How to Find Your Medi‑Cal Number: Simple Steps and What to Do If You Can’t Locate It

If you’re trying to make a doctor’s appointment, fill a prescription, or complete paperwork, you may be asked for your Medi‑Cal number (also called your Medicaid ID, Benefits Identification Number (BIC), or Member ID). Misplacing it is very common—and usually fixable with a few straightforward steps.

This guide walks you through how to find your Medi‑Cal number, what documents to check, who to call, and what to do if you’ve lost your card or changed health plans.

What Is a Medi‑Cal Number and Why Does It Matter?

Your Medi‑Cal number is a unique ID used to:

• Verify that you’re enrolled in Medi‑Cal
• Let doctors, hospitals, and pharmacies bill correctly
• Connect your records across different providers and plans

Depending on where you see it, your Medi‑Cal number may be called:

• Benefits Identification Number (BIC) – on your state-issued Medi‑Cal card
• Member ID – on your managed care health plan card
• Medi‑Cal ID or Medicaid ID – in letters and forms

You usually need this number when:

• Making medical or dental appointments
• Filling prescriptions
• Updating your information with a county office
• Creating an account with your health plan or online portal

The good news: in most cases you do not need to know it from memory—you just need to know where to find it.

First Place to Look: Your Medi‑Cal ID Card (BIC)

The easiest way to find your Medi‑Cal number is on your Medi‑Cal ID card, often called the BIC (Benefits Identification Card).

What the BIC Usually Looks Like

While designs may vary over time, a typical Medi‑Cal ID card:

• Is a plastic card, often a light color
• Lists your name
• Shows a 9‑digit or 10‑digit ID number
• May include the word Medi‑Cal, State of California, or similar markings

Your Medi‑Cal number is usually printed near:

• “ID” or “Identification Number,” or
• “CIN” (Client Index Number), in some cases

If you still have your original card, this is usually the fastest way to confirm your number.

Other Documents That May Show Your Medi‑Cal Number

If you can’t find your physical card, your Medi‑Cal number may also appear on:

1. Health Plan Insurance Card

Many people with Medi‑Cal are enrolled in a managed care health plan (for example, an HMO that partners with Medi‑Cal).

Your health plan card will often show:

• Member name
• Plan name
• Member ID or Subscriber ID

In many situations, that Member ID is the number providers use to confirm your Medi‑Cal coverage. It may or may not match the number on your state Medi‑Cal ID card, but it typically functions in a similar way when you get care through that plan.

👉 Tip: When making an appointment, you can usually provide either your Medi‑Cal BIC # or your health plan Member ID #, depending on what the office requests.

2. Medi‑Cal Approval or Renewal Letters

Check your mail or any saved paperwork from your county or state Medi‑Cal office. These letters often include:

• Your name
• Your Medi‑Cal case number
• In some cases, your Medi‑Cal ID or BIC number

Look for headings like:

• “Notice of Action”
• “Eligibility Notice”
• “Approval of Medi‑Cal Benefits”
• “Renewal Reminder”

Not every letter lists the full Medi‑Cal ID number, but they can still be helpful when you contact your county office for assistance.

3. Online Accounts and Portals

In some counties and health plans, you may be able to view your Medi‑Cal information online.

Common options might include:

• A county benefits portal account you created when you applied
• Your managed care health plan member account
• A general state or county “My Benefits” or similar website

Once logged in, look for:

• “Member ID”
• “Client ID” or “CIN”
• “Coverage details” or “Eligibility summary”

Even if your Medi‑Cal number isn’t displayed directly, you can often see your plan Member ID, which most providers can use to verify coverage.

4. Pharmacy Records or Receipts

If you’ve filled prescriptions using Medi‑Cal:

• The pharmacy’s system may show your Medi‑Cal or plan Member ID
• Some prescription labels or receipts may list an ID number

A pharmacy usually cannot give you a state-issued ID number as official proof, but they may be able to help confirm which plan you are under and what information they have on file. That can make it easier when you contact Medi‑Cal or your plan directly.

How to Find Your Medi‑Cal Number If You Lost Your Card

If none of the above options work, there are still reliable ways to recover your Medi‑Cal number or get a new card.

Step 1: Contact Your County Medi‑Cal Office

Medi‑Cal is administered at the county level, so your local county social services or human services department is often the best starting point.

When you call or visit, be prepared to verify:

• Full legal name
• Date of birth
• Current address and phone number
• Social Security Number (if you have one on file)
• Any case number or letter you have

They can typically:

• Confirm that you are currently enrolled
• Give you guidance on your Medi‑Cal ID number or how it appears in their systems
• Request a replacement BIC if your card is lost, stolen, or damaged

Some offices may not give the full ID number over the phone for privacy reasons but can mail you a new card or tell you what to bring in person.

Step 2: Call Your Medi‑Cal Managed Care Health Plan (If You Have One)

If you are enrolled in a specific Medi‑Cal health plan (for example, an HMO network), you can also contact their Member Services line.

They may be able to:

• Confirm your plan Member ID
• Send you a replacement health plan card
• Tell you what information to provide to your doctor or pharmacy in the meantime

Even if this Member ID is not the same as the number on your state BIC, many providers can use it to verify coverage and proceed with care.

Step 3: Visit Your Local Office in Person (If Possible)

If phone options are limited, or if your identity cannot be verified remotely, staff may ask you to visit in person.

Bring as many of the following as you can:

• Government-issued photo ID (if available)
• Any Medi‑Cal or benefits letters
• Proof of address (such as a rental agreement or utility bill)
• Social Security card or number (if you have one)

Once verified, staff may help you:

• Confirm your Medi‑Cal number
• Request a replacement card
• Update your contact information to avoid future mail problems

If You Recently Applied and Haven’t Received a Number Yet

If you just applied for Medi‑Cal, you may be:

• Waiting for approval
• Approved, but your card is still being mailed
• Missing some required documents or details

If you haven’t received a Medi‑Cal number yet:

1. Check your mail carefully, including any recent official envelopes.
2. Contact your county Medi‑Cal office and ask:
   • Whether your application is pending, approved, or denied
   • Whether a BIC has been issued
   • When you can expect to receive your Medi‑Cal card

Sometimes you may receive a case number before you see your actual BIC. This case number can still help staff look up your record if you need assistance.

What If My Name Changed or I Moved?

Life changes like moving, getting married, or changing your legal name can affect how your information appears in Medi‑Cal records.

If Your Name Changed

If you changed your:

• Last name (for example, after marriage or divorce)
• First name or legal identity information

You may need to:

1. Update your Social Security records (if applicable).
2. Provide legal documents (like a court order or marriage certificate) to your county Medi‑Cal office.
3. Request an updated Medi‑Cal card with your correct name.

Your Medi‑Cal ID number often stays the same, but the name on the card should match your current legal name to avoid confusion at appointments.

If You Moved

If you moved within California:

• Update your address with your county Medi‑Cal office.
• In some cases, if you move to a different county, your case may be transferred, but your Medi‑Cal number may remain connected to your state record.
• Be sure to check where your mail is going, so new cards or notices reach you.

Keeping your address current helps avoid problems like:

• Medi‑Cal renewal notices going to your old home
• Cards or important letters being lost or delayed

Can My Doctor or Pharmacy Tell Me My Medi‑Cal Number?

Experiences may vary, but in many situations:

• Doctor’s offices and pharmacies can see your ID number in their billing systems if you have used your coverage there before.
• They may be limited in what they can share directly due to privacy rules or office policies.

However, they can often:

• Confirm whether they can locate your record with your name, date of birth, and other details
• Tell you what ID number they have on file for billing
• Advise whether they need your state BIC, your plan Member ID, or both

This can sometimes get you through an appointment or refill while you wait for an official replacement card.

Is My Medi‑Cal Number the Same for Life?

In many cases, your Medi‑Cal ID (BIC/CIN) is a long-term identifier attached to you in the system. However:

• You may receive new physical cards over time (for example, replacements or updated designs).
• If you switch between different Medi‑Cal health plans, your plan Member ID might change, even though your underlying Medi‑Cal record stays linked to you.

When in doubt, keep both:

• Your state Medi‑Cal card (BIC)
• Your current health plan card

Bring both cards to appointments if you have them.

How to Protect Your Medi‑Cal Number

Because your Medi‑Cal number is part of your personal information, it’s worth protecting it carefully.

Practical tips:

• Keep your card in a safe but accessible place (like a wallet you regularly carry).
• Avoid sharing your Medi‑Cal number over unsecured email or text messages.
• Be cautious of unsolicited calls asking for your Medi‑Cal number or other personal details.
• If your card is lost or stolen, contact your county office and, if applicable, your health plan to report it and request replacements.

If you suspect someone is using your information without permission, report it to your county office and ask what steps you can take to protect your benefits.

When You Still Can’t Find Your Medi‑Cal Number

If you’ve:

• Checked your card(s) and paperwork
• Logged into any available online accounts
• Called your county Medi‑Cal office
• Contacted your health plan

…and you still can’t confirm your Medi‑Cal number, the most reliable next steps are:

1. Ask specifically whether a BIC has been issued to you.
2. Request a replacement Medi‑Cal card and ask how long it will take to arrive.
3. Ask whether you can receive care in the meantime using:
   • Your case number
   • A temporary eligibility letter
   • Your plan Member ID, if you have one

Staff can explain what documentation local providers typically accept while you wait for your card.

Key Takeaways: How to Find Your Medi‑Cal Number

• Your Medi‑Cal number may also be called your BIC, CIN, Member ID, or Medi‑Cal ID.
• The best places to look are:
  • Your Medi‑Cal ID card (BIC)
  • Your managed care health plan card
  • Recent Medi‑Cal letters or notices
  • Your online county or health plan account

Once you know where your Medi‑Cal number appears and who to contact if something goes missing, it becomes much easier to manage appointments, prescriptions, and paperwork with confidence.
