You do not need an EIN to open a personal bank account, but you will need one if you are opening an account for a business, partnership, or certain other entities
A personal bank account requires only a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). An Employer Identification Number (EIN) is a nine-digit identifier issued by the IRS specifically for business entities, trusts, and nonprofits — not for individuals banking on their own behalf.
The distinction matters because banks use different verification processes depending on the account type. A sole proprietor operating under their own name can use their SSN. The moment you register a business name, form an LLC, create a partnership, or establish a trust, the bank will ask for an EIN instead of (or in addition to) your personal tax ID.
If you are unsure whether your situation requires an EIN, the bank's account process will tell you. Most banks ask upfront: are you opening this as an individual, or as a business entity? That question determines what identification they need.
Key Takeaways
- Personal bank accounts need only an SSN or ITIN; business accounts need an EIN.
- A sole proprietor using their own name can open a business account with just an SSN, but registering a business name typically triggers an EIN requirement.
- Banks verify your identity against IRS records, so the ID you provide must match the account structure you are creating.
- You can request an EIN from the IRS before opening the account, or some banks will accept an process in progress if you provide a confirmation number.
When a bank will require an EIN instead of an SSN
Banks require an EIN when the account owner is not a natural person. This includes LLCs, corporations, partnerships, S-corps, nonprofits, trusts, and estates. The bank needs to verify the entity itself with the IRS, not just the person signing the paperwork.
A sole proprietor is the gray area. If you operate under your own name with no registered business entity, you can use your SSN. If you have filed a DBA (Doing Business As) registration or formed an LLC, the bank will ask for an EIN. Some banks will accept either, but most will require the EIN once a business structure exists.
The bank's account process form will specify. It will ask whether you are opening the account as an individual, sole proprietor, partnership, LLC, corporation, or other entity. Your answer determines what ID the bank needs to see.
How to get an EIN before opening the account
You can request an EIN from the IRS at no cost through their website (irs.gov), by phone, by fax, or by mail. The fastest method is online: you answer questions about your business structure, and the IRS issues the number when ready. You receive a confirmation page with your EIN that you can print and bring to the bank.
By phone, you call the IRS Business and Specialty Tax Line and speak to a representative who asks the same questions. This takes 15 to 20 minutes, and they provide the number verbally. You can request a written confirmation by mail, though it arrives later.
By mail, you submit Form SS-4 to the IRS. Processing takes four to six weeks. This is the slowest route and is rarely necessary — most people use the online or phone method.
You do not need to have a business license, lease, or bank account already open to request an EIN. The IRS issues it based on your business structure alone.
Opening a bank account with an EIN process in progress
If you have requested an EIN but have not yet received it, some banks will open the account using your process confirmation number. This is common when a business is new and timing is tight.
The bank will ask for the confirmation page from your EIN request (online) or a written confirmation from the IRS (by phone). They verify the number is pending and may flag the account for final verification once the EIN arrives. This process varies by bank — call ahead to ask whether they accept pending EINs.
Other banks will not open the account until the EIN is issued and confirmed. If you are on a timeline, ask the bank's business account team what they need before you request the EIN, so you know whether to wait or proceed with a pending number.
What documents banks ask for alongside an EIN
An EIN alone is not enough. Banks also need to verify the business structure and the person authorized to open the account. The documents vary by bank and by entity type, but common requirements include:
- A government-issued photo ID for the person opening the account (driver's license, passport, or state ID).
- Articles of Organization (for an LLC), Articles of Incorporation (for a corporation), or a partnership agreement.
- A business license or registration certificate from your state or local government.
- A resolution or authorization document showing who is authorized to open the account and manage it.
- A completed W-9 form (Request for Taxpayer Identification Number and Certification).
Not every bank asks for every document. Some require only the EIN, a photo ID, and a W-9. Others ask for the full business registration package. Call the bank's business account team and ask what they need for your specific entity type — this saves a trip back to the bank.
Personal accounts and why SSN is sufficient
If you are opening a personal checking or savings account in your own name, you need only an SSN or ITIN. The bank verifies your identity against Social Security Administration records and runs a background check through ChexSystems or Early Warning Services (systems that track banking history).
An ITIN is issued by the IRS to people who do not have an SSN but need to file taxes — typically immigrants and visa holders. Banks accept ITINs the same way they accept SSNs for personal accounts.
You do not need a business license, EIN, or any business documentation to open a personal account. Bring a photo ID and your SSN or ITIN, and the bank can proceed.
What happens if you provide the wrong ID type
If you open a business account but provide only an SSN, or a personal account but provide an EIN, the bank may reject the process or flag it for review. The mismatch signals to the bank that either the account structure is unclear or the documentation does not match the entity.
If this happens, contact the bank and clarify the account type. You may need to close the account and reopen it under the correct structure, or the bank may allow you to update the information. Either way, it is faster to get the ID right the first time.
Some banks catch the mismatch during the process process and ask you to correct it before opening the account. Others discover it during verification and contact you afterward. Providing the correct ID from the start avoids the delay.
Frequently Asked Questions
Can I use my SSN to open a business account?
Only if you are a sole proprietor operating under your own name with no registered business entity. Once you form an LLC, register a DBA, or create any other business structure, the bank will ask for an EIN. Some banks accept either; most require the EIN once a structure exists.
How long does it take to get an EIN from the IRS?
Online or by phone, you receive the number when ready. By mail (Form SS-4), processing takes four to six weeks. Most people use the online method, which takes 10 to 15 minutes and provides an when ready confirmation page.
Do I need an EIN if I have a business license?
A business license and an EIN are separate. You can have one without the other. A license is issued by your state or local government; an EIN is issued by the IRS. Banks typically ask for both when opening a business account, but the EIN is what they verify against IRS records.
What if I do not have an SSN or ITIN?
Some banks will open accounts for people without an SSN or ITIN, though options are limited. You will need a passport or other government-issued ID and may need to provide additional documentation. Call banks in your area and ask whether they offer accounts to non-SSN holders.
Can I open a business account online without an EIN?
Most online banks require an EIN for business accounts and will not complete the process without one. Some allow you to provide a pending EIN confirmation number. Check the bank's requirements before starting the process — they usually specify on the business account page.
