You do not need an EIN to open a checking account for yourself

A personal checking account requires only a Social Security number, not an Employer Identification Number (EIN). Banks use your SSN to verify your identity and check your banking history through ChexSystems or Early Warning Services. If you have a valid SSN, you can open an account at any bank or credit union.

The confusion usually comes from business accounts. If you are opening a checking account in a business name — whether you are a sole proprietor, partnership, LLC, or corporation — the bank will ask for an EIN instead of (or in addition to) your SSN. But for your personal account, your SSN is all you need.

Key Takeaways

  • Personal checking accounts require only a Social Security number; an EIN is not necessary.
  • Business checking accounts require an EIN, which you obtain from the IRS before opening the account.
  • If you are self-employed but operate as a sole proprietor, you can use your SSN for a personal business account, though some banks prefer an EIN.
  • Banks verify your identity using your SSN and check your ChexSystems report, which records past account closures and fraud.
  • If you do not have an SSN, you may be able to open an account using an Individual Taxpayer Identification Number (ITIN) at some banks.

When a bank will ask for an EIN instead

Banks require an EIN when you open a business checking account under a registered business name. This applies to LLCs, corporations, partnerships, and other formal business structures. The EIN serves as the tax ID for the business itself, separate from your personal SSN.

You obtain an EIN from the IRS before you approach the bank. The process is free and takes about 15 minutes online at irs.gov (Form SS-4). Some banks will issue a temporary EIN number while you wait for the official one, but most require you to have the actual EIN in hand when you arrive to open the account.

If you are a sole proprietor operating under your own name (no separate business entity), you can technically use your SSN for a business account. However, many banks now prefer an EIN even for sole proprietors, so it is worth getting one if you plan to keep business and personal finances separate.

What happens if you do not have a Social Security number

If you are not a U.S. citizen or permanent resident and do not have an SSN, you may still open a personal checking account using an Individual Taxpayer Identification Number (ITIN). An ITIN is issued by the IRS to people who need to file taxes but are not may be able to access for an SSN.

Not all banks accept ITINs, so you will need to call ahead or visit in person to confirm. Credit unions are sometimes more flexible than large national banks on this point. You will also need a valid passport or other government-issued ID to verify your identity.

Some banks may ask additional questions or require a larger opening deposit if you are using an ITIN instead of an SSN. This varies by institution, so compare options before committing.

What banks check before opening your account

When you provide your SSN, the bank runs a background check through ChexSystems or Early Warning Services. These are banking history reports that record closed accounts, overdrafts, fraud, and other issues. The bank uses this report to decide whether to open your account and what restrictions or fees to apply.

If you have been flagged in ChexSystems — for example, because you left an account with a negative balance — some banks will deny you. Others will open an account but charge higher fees or require a larger deposit. You can request your own ChexSystems report for free at chexsystems.com to see what the bank will see.

The bank also verifies that your SSN is real and matches your name and address. If there is a mismatch, they will ask for additional documents like a driver's license or utility bill.

Opening a business account without an EIN yet

If you have just started a business and have not yet obtained an EIN, you have a few options. The fastest is to get the EIN online at irs.gov before you go to the bank — it takes 15 minutes and you receive the number immediately.

If you need the account open urgently, some banks will let you open a business account using your personal SSN temporarily, then update it to the EIN once you receive it. Call your bank ahead of time to ask whether they offer this. You will need to bring your business formation documents (articles of incorporation, LLC operating agreement, or partnership agreement) to prove the business exists.

A few banks will issue a temporary EIN number on the spot while you wait for the IRS to mail the official one, though this is less common than it used to be. Ask specifically whether your bank offers this service.

Documents to bring when you open your account

For a personal account, bring a government-issued photo ID (driver's license, passport, or state ID) and your SSN. Some banks ask for a second form of ID or proof of address, such as a utility bill or lease agreement dated within the last 60 days.

For a business account, bring your EIN documentation (the IRS letter confirming your EIN), your business formation documents, and a photo ID in your personal name. If you are opening the account as a representative of the business rather than the owner, bring a corporate resolution or power of attorney showing you have authority to open accounts on behalf of the business.

Bring a small opening deposit if required. Many banks waive the minimum deposit for certain account types, but some still require $25 to $100 to open. Ask when you call to schedule your appointment.

If the bank denies you

If a bank denies your account because of your ChexSystems report, you have options. First, check your own report at chexsystems.com to see what they reported. If there is an error, you can dispute it directly with ChexSystems.

Second, look for banks that offer second-chance checking accounts. These are designed for people with banking problems in their history and usually come with higher fees and lower limits, but they do not require a clean ChexSystems report. Credit unions often have more flexible policies than national banks.

Third, if you are opening a business account and the bank denies you because you do not have an EIN yet, simply get the EIN and try again. The denial is not about you personally — it is about the missing business tax ID.

Frequently Asked Questions

Can I use my ITIN instead of my SSN for a business account?

Some banks will accept an ITIN for a business account if you also have an EIN. The EIN is the primary identifier for the business itself. Call ahead to confirm your bank accepts ITINs, as policies vary widely.

Do I need an EIN if I am self-employed but have not registered my business?

No. If you operate as a sole proprietor under your own name, you can use your SSN for a personal checking account. You only need an EIN if you have registered a formal business entity (LLC, corporation, partnership) or if you want to keep business finances completely separate from personal ones.

What if I lost my Social Security card but remember my number?

You can open a checking account with just your SSN — you do not need the physical card. Bring a photo ID and be ready to answer security questions to verify the number is yours. If the bank cannot verify it, you can request a replacement card from the Social Security Administration before opening the account.

How long does it take to get an EIN from the IRS?

If you apply online at irs.gov, you receive your EIN immediately. If you apply by mail or fax, it takes two to four weeks. Most banks will not open a business account until you have the actual EIN in hand, so apply online to avoid delays.

Can I open a business account with just my SSN and no EIN?

Some banks allow sole proprietors to open business accounts using only an SSN, but most now require an EIN even for sole proprietors. It is faster and simpler to get the EIN first — it takes 15 minutes online — than to call around looking for a bank that will accept just your SSN.
