What Documents You Need Before You Apply for Medicaid

Gather these documents before you start your Medicaid application

You will need proof of identity, income, household size, and citizenship or immigration status. The exact documents vary by state — some accept a utility bill as proof of address, others require a lease or mortgage statement. Before you collect anything, call your state Medicaid office or visit its website to see the specific list for your situation, because submitting the wrong documents delays your case.

Most states let you submit documents by mail, email, or in person at a local office. Some have online portals where you upload files directly. A few still require you to bring originals to an appointment. Knowing your state's method ahead of time means you can gather documents in the right format — a photo of your birth certificate works for some states, but others need an official copy ordered from the vital records office.

Key Takeaways

• Every state requires proof of identity, income, household size, and citizenship or immigration status, but the acceptable documents differ by state.
• Call your state Medicaid office or check its website before gathering anything, because submitting wrong documents delays your case by weeks.
• Some states accept photos or digital copies, while others require certified originals mailed or brought in person.
• If you are missing a document, ask your Medicaid office whether you can submit an affidavit or explanation letter instead of waiting weeks for an official copy.
• Keep copies of everything you submit and note the date and method you sent it, in case your state loses a document.

Documents proving who you are

You need one form of government-issued photo ID. A driver's license, passport, state ID card, or tribal ID all work. If you do not have a photo ID, some states accept a birth certificate plus a second document with your name on it — a utility bill, lease, or Social Security card.

If you are applying for a child and do not have custody papers, bring the child's birth certificate and proof that you live together. If you are the legal guardian but not the parent, bring the guardianship order. States vary on whether they need certified copies or accept photocopies — ask your state office before you order anything.

Documents proving your income

What counts as proof depends on how you earn money. If you work for an employer, bring recent pay stubs — usually the last two or three months. If you are self-employed, bring tax returns from the last year or two, plus bank statements showing deposits. If you receive unemployment, Social Security, disability, or veteran benefits, bring a recent statement or award letter showing the monthly amount.

If you have no income, bring a statement from your bank showing zero deposits for the last month or two, or a signed letter from you stating you have no income. Some states also accept a letter from a shelter, food bank, or social service agency confirming you are unhoused or receiving emergency assistance. Do not guess at what counts — call your state office and describe your exact situation, because what works in one state may not work in another.

Documents proving your household size and relationships

You need to list everyone who lives with you and show how you are related. Birth certificates work for children. Marriage certificates work for spouses. For other household members, bring documents showing you live together — a lease or mortgage in both names, utility bills, or a school enrollment showing your address.

If you are applying for a child whose other parent does not live with you, some states ask for a birth certificate naming both parents. Others do not. If you are caring for a grandchild or other relative without legal guardianship, ask your state whether you need guardianship papers or whether a notarized statement and proof of residence is enough. This varies widely.

Documents proving citizenship or immigration status

U.S. citizens need one document showing citizenship. A birth certificate, passport, naturalization certificate, or state ID card all work. If you were born outside the U.S. and became a citizen, bring your naturalization certificate or passport.

If you are not a citizen, you need proof of your immigration status. A green card, work permit, visa, or I-94 arrival record all count. Some states cover certain immigrants even without legal status — ask your state office what documents they need and what immigration categories they cover. Do not assume you are ineligible; many states have programs you may not know about.

Documents proving where you live

You need one document showing your current address. A utility bill, lease, mortgage statement, or property tax bill all work. The document should be recent — usually from the last two months. If you are unhoused, bring a letter from a shelter or social service agency on letterhead, dated within the last month, confirming your name and that you are staying there.

If you just moved and do not have a utility bill yet, ask your state whether you can submit a lease, a letter from your landlord, or a signed statement from you with your new address. Some states accept these; others require you to wait for a utility bill. Calling ahead saves you a trip.

What to do if you are missing a document

Do not wait weeks for an official copy if you have something else. Call your state Medicaid office and ask whether you can submit what you have now and send the official document later, or whether you can write a signed statement explaining why you do not have it. Many states allow this, especially for documents like birth certificates that take time to order.

If you need a birth certificate, Social Security card, or other vital document, contact the office that issued it — the vital records office for your birth state, the Social Security Administration for a replacement card, or your state DMV for an ID. These can take weeks, so order early. Some states let you submit an affidavit (a sworn statement) in the meantime; others will hold your case open while you gather documents.

How to organize and submit your documents

Make a list of what your state requires and check off each item as you gather it. Make copies of everything before you submit — keep one set for yourself. If you are mailing documents, use certified mail with a return receipt so you know they arrived. Write your name and Medicaid case number (if you have one) on every page.

If your state has an online portal, upload documents there rather than mailing them — it is faster and you get confirmation they were received. If you are submitting by email, send one email with all documents attached and ask for a read receipt. If you are going in person, bring originals and copies; the office will keep the originals and return the copies to you.

Frequently Asked Questions

Can I submit a photo of my documents instead of the original?

It depends on your state. Some accept clear photos of documents taken with a phone camera. Others require certified copies or originals. Check your state's website or call the Medicaid office before you take photos — if they do not accept them, you will have wasted time.

What if I do not have a Social Security number?

You can still apply. Bring whatever ID you have — a passport, visa, or state ID. Your state will assign you an Individual Taxpayer Identification Number (ITIN) for Medicaid purposes if you do not have a Social Security number. Tell the Medicaid office you do not have one when you apply.

Do I need to bring documents in person, or can I mail them?

Most states let you mail or email documents. Some require an in-person interview for certain situations, like if you are applying for emergency Medicaid or if your case is flagged for verification. Call your state office to find out whether you need an appointment or can submit everything by mail.

How long does it take to get a decision after I submit my documents?

Most states aim to decide within 30 days. If documents are missing or unclear, they will contact you and give you time to send more. If you do not hear back within 45 days, call your state office and ask for a status update — sometimes documents get lost in the mail or misfiled.

What if my income changes after I submit my application?

Report the change to your state Medicaid office right away. Do not wait for your case to be decided. If your income drops, it may help your case. If it rises, it may affect your coverage. Either way, telling them now prevents problems later.
