An EDG number is your state's unique identifier for your Medicaid case

EDG stands for "may be able to access information Group" — it is the case number your state Medicaid office assigns when you first contact them about coverage. Every person or family with an open Medicaid case gets one. You will see it on approval letters, renewal notices, and any official mail from your state's Medicaid program. It is how the state tracks your case from the moment you first reach out through every renewal and change you report.

The EDG number itself does not determine whether you get Medicaid. It is straightforward the filing system your state uses. Once you have one, it means your state has opened a case file for you — but the actual decision about coverage depends on your income, household size, and the specific Medicaid program you are seeking in your state.

Different states call this number different things. Some states use "case number," others use "client ID," and a few use other terms entirely. If you are looking at mail from your state and do not see the letters "EDG," look for any number labeled as your case number or client identifier — that serves the same purpose.

Key Takeaways

  • An EDG number is your state's case identifier for Medicaid, assigned when your state opens a file for you.
  • You will find your EDG number on approval letters, renewal notices, and any official correspondence from your state Medicaid office.
  • The EDG number itself does not decide your coverage — it is only how your state tracks your case.
  • Different states may use different names for this number, such as case number or client ID, but they serve the same purpose.

Where to find your EDG number

Your EDG number appears on almost every official document your state Medicaid office sends you. Check your approval letter first — it is usually printed near the top or bottom, often labeled clearly as "EDG Number" or "Case Number." If you have received a renewal notice, a change notice, or any letter about your Medicaid status, the number will be there.

If you have lost the paperwork, you can call your state Medicaid office directly and give them your name and date of birth. They will look up your case and read the number to you over the phone. You can also log into your state's online Medicaid portal if your state offers one — most states now have a website where you can view your case details, including your EDG number.

Keep your EDG number in a safe place. Write it down or take a photo of it. You will need it if you call your state Medicaid office with questions, if you need to report a change in your household or income, or if you are renewing your coverage.

Why your state asks for your EDG number

When you call your state Medicaid office or log into an online portal, the staff member or system will ask for your EDG number because it pulls up your entire case file when ready. Instead of spelling out your full name, your address, and your date of birth, you can straightforward give the number. This makes the process faster and reduces the chance of the state pulling up the wrong person's file.

If you do not have your EDG number when you call, the state can still find your case using your name and date of birth, but it takes longer. Having the number ready saves time, especially if you are calling during busy periods when wait times are long.

EDG number versus your Medicaid card number

Your EDG number and your Medicaid card number are not the same thing. Your EDG number is the case identifier your state uses internally to track your file. Your Medicaid card number is printed on the physical or digital card you use when you see a doctor or go to a pharmacy. The card number is what you show to providers.

You may have one EDG number but multiple card numbers if you have been on Medicaid for a long time and your state has issued you new cards over the years. The EDG number stays the same; the card number changes when your card is renewed or reissued.

What happens if you lose track of your EDG number

Losing your EDG number is not a problem. You can always call your state Medicaid office and ask them to look up your case using your name and date of birth. They will give you the number, and you can write it down for future reference. There is no penalty for not having it memorized or on hand.

If you are worried about keeping track of important Medicaid information, consider creating a straightforward folder — physical or digital — where you keep copies of your approval letter, renewal notices, and any other mail from your state. Your EDG number will be on all of these documents, so you will always have it available when you need it.

How EDG numbers work across state lines

If you move to a different state, your old EDG number does not follow you. Each state runs its own Medicaid program with its own case management system. When you move, you will need to contact your new state's Medicaid office to open a new case, and you will receive a new EDG number.

Your old state's EDG number becomes inactive once you move, but the state keeps the file on record. If you ever need to reference your old coverage history — for example, to prove you had Medicaid during a certain period — you can contact your former state's Medicaid office and reference your old EDG number.

Frequently Asked Questions

What if the number on my Medicaid card does not match my EDG number?

That is normal. Your Medicaid card number and your EDG number are two different numbers that serve different purposes. The card number is what you show to doctors and pharmacies. The EDG number is what your state uses to track your case internally. Both are correct and both belong to you.

Can I use my EDG number to check my Medicaid status online?

Yes, most states allow you to log into their Medicaid portal using your EDG number along with a password or PIN. Check your state's Medicaid website to see if an online portal is available. If your state offers one, you can view your case details, check your coverage status, and report changes without calling.

Do I need my EDG number to renew my Medicaid?

You do not need it to start the renewal process, but having it makes things faster. When you renew, your state will send you a renewal notice that includes your EDG number. If you call to renew by phone, giving your EDG number helps the staff member pull up your file right away.

What if I have multiple EDG numbers?

This can happen if you have opened separate cases at different times or if your state created a new case file for you during a system update. Contact your state Medicaid office to clarify which case is active. They can merge old cases or explain which number you should use going forward.
