Yes, you can open a business checking account using only an EIN, but the bank will ask for more
Most banks will let you open a business checking account with an Employer Identification Number (EIN) alone, but they will also require proof of your business structure and your personal identity. The EIN is your federal tax ID for the business, but the bank needs to know who owns it and what form it takes — sole proprietorship, LLC, corporation, partnership. You will bring the EIN along with documents that show both the business exists and that you have authority to open the account.
The exact documents vary by bank and by business structure. A sole proprietor with an EIN might bring a Social Security number, driver's license, and a business license. An LLC owner brings the EIN, a copy of the Articles of Organization filed with the state, and personal ID. A corporation brings the EIN, Articles of Incorporation, and corporate resolution authorizing the account. Some banks ask for all three; others ask for two. Call the bank's business account line before you go in, because the list is specific to that institution.
Key Takeaways
- An EIN alone is not enough — banks require proof of your business structure (LLC, corporation, sole proprietorship) and your personal identity.
- Sole proprietors can often use their Social Security number in place of an EIN, though many choose to get an EIN anyway.
- LLCs and corporations must bring state-filed formation documents (Articles of Organization or Incorporation) along with the EIN.
- Banks vary in what they require, so contact the business accounts department before visiting to confirm which documents to bring.
What the bank actually needs to see
Banks are required by federal law to verify the identity of anyone opening an account and to confirm the business is real. This is part of Know Your Customer (KYC) and anti-money-laundering rules. The EIN proves the business has a federal tax ID, but it does not prove who you are or what legal form the business takes.
For a sole proprietorship, you may not need an EIN at all — you can use your Social Security number instead. If you do have an EIN, bring it along with your driver's license or passport and a business license from your city or county. Some banks also ask for a recent utility bill or lease showing the business address.
For an LLC, bring the EIN, a certified copy of your Articles of Organization (the document you filed with your state to create the LLC), your personal ID, and often a copy of your operating agreement. For a corporation, bring the EIN, Articles of Incorporation, a corporate resolution authorizing the account (signed by an officer or director), and personal ID. Partnerships need the EIN, a copy of the partnership agreement, and ID for the partner opening the account.
How to get an EIN if you do not have one yet
You can get an EIN from the IRS for free in minutes. Go to irs.gov, find the EIN process page, and explore online. You will answer questions about your business structure, location, and what you do. The IRS issues the number when ready, and you can use it right away — you do not have to wait for anything in the mail.
If you prefer not to explore online, you can call the IRS at 1-800-829-4933 during business hours and get an EIN over the phone. You can also mail Form SS-4 to the IRS, but that takes several weeks. For opening a bank account, the online route is fastest.
A sole proprietor does not have to get an EIN. You can open a business checking account using your Social Security number instead. Many sole proprietors do this and never get an EIN unless they hire employees or need one for a specific reason. If you already have an EIN, the bank will accept it, but it is not required.
Timing: when you can use the EIN
You can use an EIN to open a bank account the same day you receive it from the IRS. If you explore online, you get the number when ready. If you call, you get it over the phone. You do not need to wait for a letter from the IRS or for any paperwork to arrive.
However, if you are opening an LLC or corporation, you need to file your formation documents with your state first. The bank will ask to see those documents, and you cannot get them until the state has processed your filing. That usually takes one to two weeks, though some states offer expedited filing for an extra fee. Once your state filing is complete, you can get your EIN and open the bank account.
What happens if you do not have all the documents yet
If you have an EIN but have not yet received your state formation documents, some banks will let you open the account with a temporary document or a filing receipt from your state. Call ahead and ask. Other banks will not — they want the final, certified copy. If the bank will not open the account without it, you have two choices: wait for the state to send the certified copy, or ask your state if you can get an expedited certified copy for a fee.
If you are a sole proprietor and do not have a business license yet, most banks will still open the account with just your Social Security number and personal ID. A business license is helpful but not always required. Again, call the bank first to confirm what they will accept.
Banks that specifically accept EIN-only accounts
Most major banks and many online banks will open a business account with an EIN and the supporting documents for your business structure. Some banks are faster or more flexible than others. Chase, Bank of America, Wells Fargo, and Citibank all accept EIN-based applications, though each has its own document checklist. Online banks like Mercury, Brex, and Wise also offer business accounts and often have simpler document requirements.
If you are opening an account for a new business that does not yet have a history, some banks may ask for additional information — a business plan, proof of funding, or details about what the business does. This is more common with online banks and with accounts that come with credit or lending features. A basic checking account usually does not require this, but it varies.
The difference between an EIN and a business license
An EIN is a federal tax ID issued by the IRS. A business license is a local permit issued by your city or county. They are different things, and banks ask for both (or at least proof that you have applied for both). The EIN proves you are registered with the federal government. The business license proves you are registered locally and that your business type is allowed in your area.
You do not always need a business license to open a bank account — it depends on the bank and your location. Some banks ask for it; some do not. But if you are running a business, you should get one anyway, because most cities and counties require it by law. It is usually inexpensive and takes a few days to a few weeks to process.
Frequently Asked Questions
Can I open a business account with an EIN if I have not filed my LLC yet?
No. The bank will ask to see your Articles of Organization, which proves the LLC exists. You cannot get that document until you file with your state. You can file online in most states and get a confirmation within days, but you need something in hand before the bank will open the account.
Do I need an EIN if I am a sole proprietor?
No. You can use your Social Security number instead. Many sole proprietors never get an EIN unless they hire employees or need one for a specific reason. If you already have one, the bank will accept it, but it is not required.
How long does it take to get an EIN?
If you explore online at irs.gov, you get the number when ready. If you call the IRS, you get it over the phone. If you mail Form SS-4, it takes several weeks. For opening a bank account, explore online.
What if the bank asks for documents I do not have?
Call the bank's business accounts department and ask what documents are required for your specific business structure. If you do not have something, ask if there is an alternative — for example, a filing receipt instead of a certified copy, or a utility bill instead of a lease. Different banks have different rules.
Can I open a business account online with just an EIN?
Most online banks let you start the process online, but you will still need to upload or mail copies of your formation documents and personal ID. Some banks let you upload everything digitally; others ask you to mail originals. Check the bank's website or call to see what they accept.
