Most people don't need an EIN to open a personal checking account
A personal checking account requires a Social Security number, not an EIN. Banks use your SSN to verify your identity and run a background check through ChexSystems or Early Warning Services. If you have a valid SSN, you can open a checking account at any bank or credit union without an EIN.
An EIN (Employer Identification Number) is a nine-digit number issued by the IRS specifically for business entities. It functions like a Social Security number for a business—sole proprietorships, partnerships, corporations, nonprofits, and trusts use them for tax purposes and to hire employees. Banks only ask for an EIN when you're opening a business checking account, not a personal one.
The confusion usually arises because both numbers serve identification purposes, and both appear on banking paperwork. But they're used in different contexts. Your bank will ask for your SSN on a personal account process and your EIN on a business account process. You don't need both for the same account.
Key Takeaways
- Personal checking accounts require a Social Security number; banks will not ask for an EIN unless you're opening a business account.
- An EIN is issued by the IRS to businesses, nonprofits, and trusts—not to individuals—and is only needed if your account is registered to a business entity.
- If you don't have an SSN but are a non-citizen, some banks will open accounts using an ITIN (Individual Taxpayer Identification Number) instead.
- Business accounts require both an EIN and proof of business formation documents like articles of incorporation or a DBA filing.
When banks ask for an EIN instead of an SSN
Banks request an EIN when you're opening an account in the name of a business, not in your personal name. This includes sole proprietorships that operate under a business name (a DBA, or "doing business as"), partnerships, LLCs, S-corporations, C-corporations, nonprofits, and trusts. The account itself belongs to the business entity, not to you as an individual.
If you're a sole proprietor operating under your own name with no employees, you technically don't need an EIN—you can use your SSN instead. But many sole proprietors obtain an EIN anyway to keep their personal and business finances separate on the bank's records. This is optional, not required.
When you open a business account, the bank will ask for the EIN, your personal SSN (as the account owner or authorized signer), and documentation proving the business exists. That documentation varies by business type: articles of incorporation for a corporation, an operating agreement for an LLC, a DBA certificate from your county or state, or a nonprofit information letter from the IRS.
What to bring if you don't have an SSN
Non-citizens and some visa holders can open personal checking accounts using an ITIN (Individual Taxpayer Identification Number) instead of an SSN. An ITIN is issued by the IRS to people who need to file taxes but don't have a Social Security number. Banks accept ITINs as a valid form of identification for personal accounts.
To open an account with an ITIN, bring the ITIN itself, a valid passport or visa, and proof of address (a utility bill, lease, or government-issued ID). Some banks may ask additional questions about your immigration status or employment, but this is routine verification, not a barrier to opening the account.
If you're in the US on a work visa and your employer has obtained an EIN for your company, that EIN belongs to the employer, not to you. You would still use your SSN or ITIN to open your personal checking account. The employer's EIN is separate and used only for business tax filings and payroll.
The difference between personal and business account requirements
| Account Type | Primary ID Required | Additional Documents | Who the Account Belongs To |
|---|---|---|---|
| Personal checking | Social Security number or ITIN | Valid ID, proof of address | You as an individual |
| Business checking (sole proprietor with DBA) | EIN or SSN | DBA certificate, business license, personal ID | The business entity |
| Business checking (LLC, corporation, nonprofit) | EIN | Articles of incorporation, operating agreement, or information letter; personal ID of authorized signer | The business entity |
| Trust account | EIN (if the trust has one) or SSN of trustee | Trust document, trustee ID | The trust |
How to get an EIN if you need one
If you're opening a business account and don't have an EIN, you can obtain one from the IRS at no cost. The fastest method is to explore online at irs.gov using Form SS-4. The online process takes about 15 minutes, and you receive your EIN when ready upon completion. You can then use that number right away when opening your business account.
You can also explore by phone (1-800-829-4933), by mail using a paper Form SS-4, or through a tax professional. Phone applications are processed the same day during business hours. Mail applications take about four weeks. Most banks will not hold an account open while you wait for an EIN by mail, so the online or phone route is practical if you need the account quickly.
Have your business formation documents ready before you explore for an EIN. The IRS will ask what type of business entity you have (sole proprietor, LLC, corporation, etc.), the business name, the business address, and the names and SSNs of owners. If you haven't yet registered your business with your state, you can still get an EIN—you don't need state registration first.
What happens if you give the bank the wrong number
If you accidentally provide an EIN on a personal account process or an SSN on a business account process, the bank will catch it during verification. Banks run the number through the IRS database to confirm it matches the account type. A mismatch will delay the account opening while the bank contacts you to correct it.
This is a common mistake and easily fixed. straightforward call the bank, confirm which type of account you're opening, and provide the correct number. The bank will update the process and resubmit it. There's no penalty or rejection—it's treated as a data entry error.
If you're unsure which number to use, ask the bank directly before you submit the process. The account representative can tell you exactly what they need based on whether you're opening a personal or business account.
Frequently Asked Questions
Can I open a personal checking account without an SSN or ITIN?
No. Banks are required by federal law to verify your identity using either an SSN or ITIN. If you don't have either, you'll need to obtain an ITIN from the IRS first. Some banks may also accept a valid passport and visa as supplementary identification, but the SSN or ITIN is mandatory.
Do I need an EIN if I'm a freelancer or contractor?
No. As a freelancer or independent contractor, you can open a personal checking account using your SSN. An EIN is optional unless you plan to hire employees or want to keep your business finances completely separate from your personal finances. Many freelancers use their SSN for their business banking.
What if my business doesn't have an EIN yet but I need to open a checking account?
You can obtain an EIN online from the IRS in about 15 minutes at irs.gov using Form SS-4. Once you have it, you can open the business account when ready. If you're a sole proprietor operating under your own name, you can use your SSN instead while you decide whether to get an EIN.
Can I use someone else's EIN to open a checking account?
No. The EIN must belong to the business entity that owns the account. Using someone else's EIN is fraud and will be discovered during the bank's verification process. If you're opening an account for a business you don't own, you'll need written authorization from the owner and documentation proving your authority to act on behalf of the business.
Do I need an EIN to open a joint checking account with my spouse?
No. Joint personal checking accounts use the SSNs of both account holders, not an EIN. An EIN is only needed if the account is registered to a business entity, not to individuals.
