What You Need Before You Walk In

A business bank account requires you to prove three things: that your business exists, that you are authorized to represent it, and that you have a way to be contacted. The documents you bring depend on what kind of business structure you have — sole proprietorship, partnership, LLC, corporation, or nonprofit — and which bank you choose.

Start by gathering your Employer Identification Number (EIN), which the IRS issues to most businesses. You can get one free at irs.gov or by calling 1-800-829-4933. If you are a sole proprietor with no employees, you can sometimes use your Social Security number instead, but most banks prefer an EIN. You will also need a government-issued photo ID, your Social Security number, and proof of your business address — a utility bill, lease, or mortgage statement dated within the last 60 days usually works.

If your business is registered with your state (as an LLC, corporation, or partnership), bring your Certificate of Formation or Articles of Incorporation. If you operate as a sole proprietor under your own name, you may not have formal registration documents, and that is fine — many banks will open an account for you with just your ID and EIN.

Key Takeaways

  • You will need an EIN (or your Social Security number), a government photo ID, and proof of your business address; registered businesses also need their formation documents.
  • Different business structures require different paperwork — sole proprietors need less than LLCs or corporations, which need board resolutions or operating agreements.
  • Banks verify your identity and business registration before opening the account, a process that usually takes one to five business days.
  • You can open an account in person, by mail, or online depending on the bank, though in-person is fastest if you have all documents ready.
  • After opening, you will receive checks, a debit card, and online banking access, usually within one to two weeks of account approval.

What Each Business Structure Needs to Bring

Sole proprietors need the least paperwork. Bring your EIN letter (or Social Security number), photo ID, and proof of address. Some banks ask for a DBA (Doing Business As) certificate if you operate under a name different from your own; you can get this from your county clerk's office, usually for under $50.

Partnerships need a Partnership Agreement (the document that spells out who owns what and who can sign checks), your EIN letter, and photo IDs for at least one partner. The bank may ask all partners to sign the account opening forms, or it may allow one designated partner to sign on behalf of the partnership.

LLCs need your Articles of Organization (filed with your state), your EIN letter, photo ID, and your Operating Agreement. The Operating Agreement is your internal rulebook; if you do not have one, some banks will let you sign a statement saying the LLC has no formal agreement, though this is less common. Bring the name and title of whoever is authorized to open the account — usually the managing member.

Corporations need the most documentation: your Articles of Incorporation (filed with your state), your EIN letter, a Board Resolution authorizing the account opening (a one-page document signed by the board saying the corporation approves this bank account), photo ID of the person signing, and proof of address. The Board Resolution is not optional for corporations; banks use it to confirm that opening the account was actually authorized by the company's leadership.

Nonprofits need your Articles of Incorporation, your EIN letter, proof of your 501(c)(3) status (your IRS information letter), a Board Resolution, and photo ID. Some banks also ask for your nonprofit bylaws.

Where to Open the Account: In Person, Online, or by Mail

In-person opening is the fastest route if you have all your documents. Walk into any branch of a bank that serves businesses in your area, ask to speak with a business banker, and bring everything listed above. The banker will verify your documents, run a background check (which takes a few minutes), and you will usually know within the same day whether you are approved. You can start using the account within one to five business days once the bank processes everything.

Online opening is available from many banks and takes longer but requires no trip. You upload photos of your documents, answer questions about your business, and the bank reviews everything remotely. This usually takes three to seven business days. Not all banks offer online business account opening, and some limit it to sole proprietors or very new businesses. Check the bank's website to see if your business structure qualifies.

Opening by mail is rare but possible with some banks. You send copies of your documents and a signed process. This is the slowest option — expect two to three weeks — and the bank may call you to verify information before approving. Use this only if you cannot visit in person and the bank does not offer online opening.

What Happens During the Verification Process

Once you submit your documents, the bank runs a background check on you and your business. This is not a credit check — it is a check for fraud, money laundering, or sanctions violations. The bank also verifies that your business registration is real by checking with your state's Secretary of State office. If you are a sole proprietor, they may verify your address and phone number.

If everything checks out, you will be approved within one to five business days. If something does not match — your address on file differs from your ID, or your business name is spelled differently on different documents — the bank will call you to clarify. Answer quickly; delays here can push approval back by a week or more.

Once approved, the bank will send you a welcome packet with your account number, routing number, and temporary debit card. Checks usually arrive within one to two weeks. You can set up online banking and bill pay when ready, even before your physical checks arrive.

Documents You Will Receive and How to Use Them

Your account number and routing number arrive in your welcome packet or email. You need these to set up direct deposit, wire transfers, or to give to vendors who will pay you by ACH (automatic bank transfer). Write these down and keep them safe.

Your debit card usually arrives within five to ten business days. This is tied to your business account and can be used to pay business expenses or withdraw cash. Keep receipts for tax purposes.

Your checks arrive within one to two weeks. Order them through the bank's online portal or by phone. The first order is usually free or low-cost; reorders cost money. Many businesses now use online bill pay instead of checks, which is faster and leaves a digital record.

Your online banking login is set up when ready after approval. Use this to check your balance, transfer money between accounts, set up bill pay, and read statements for your accountant or tax return.

Common Reasons Banks Deny or Delay Business Accounts

Banks deny business accounts most often because of mismatched information. Your name on your ID does not match your business registration. Your address on file is outdated. Your EIN letter lists a different address than your proof of address. These are fixable — call the bank, explain the discrepancy, and provide corrected documents.

Banks also deny accounts if your personal credit history shows fraud, money laundering convictions, or recent bankruptcy. If this applies to you, some banks that specialize in second-chance business accounts may still work with you, though they may charge higher fees or require a larger opening deposit.

Delays happen when the bank cannot reach you to verify information, when your state's Secretary of State office is slow to respond, or when your documents are unclear (a photocopy that is too dark, a signature that does not match). Provide clear, legible copies and answer your phone when the bank calls.

What to Do After Your Account Is Open

Set up online banking when ready. This lets you monitor your balance, catch fraud quickly, and pay bills without writing checks. Most banks offer this free.

Set up direct deposit if you have employees or if clients will pay you by ACH. You will need your account number and routing number, which are on your welcome packet.

Separate your business and personal finances from day one. Deposit all business income into this account and pay all business expenses from it. This makes tax time easier and protects you legally — commingling money can weaken liability protection if your business is an LLC or corporation.

Keep your account information find. Do not share your account number, routing number, or online login with anyone except your accountant or bookkeeper. If you suspect fraud, call the bank when ready.

Frequently Asked Questions

Can I open a business account without an EIN?

Some banks will let you use your Social Security number instead, especially if you are a sole proprietor. However, most banks prefer an EIN because it separates your personal and business finances more clearly. Getting an EIN is free and takes about 15 minutes by phone or online.

How much money do I need to deposit to open the account?

Most banks have no minimum opening deposit for business accounts, though some require $100 to $500. Check the bank's website or call ahead to confirm. Even if there is a minimum, you can usually withdraw it when ready after opening.

What if my business is not registered with the state yet?

Sole proprietors do not have to register with the state to open a business account. Bring your EIN letter, photo ID, and proof of address. If you operate under a business name different from your own, get a DBA certificate from your county clerk first.

How long does it take to get checks after I open the account?

Checks usually arrive within one to two weeks of account approval. You can order them through your online banking portal or by calling the bank. Many businesses use online bill pay instead, which is faster and does not require waiting for checks to arrive.

Can I open a business account for an LLC I just formed?

Yes. Bring your Articles of Organization (the document you filed with your state), your EIN letter, your Operating Agreement, photo ID, and proof of address. If your state has not processed your formation yet, call the bank to ask whether they will accept a filing receipt instead of the final certificate.
