Documents and information you'll bring to the bank
To open a business checking account, you need to prove who you are, prove your business exists, and show the bank who has authority to sign checks. The exact documents depend on your business structure — sole proprietorship, partnership, LLC, or corporation — but most banks follow the same basic pattern.
Start with a government-issued ID for yourself: a driver's license or passport. The bank will scan this and verify it matches their records. You'll also need your Social Security number or Employer Identification Number (EIN). If you're a sole proprietor operating under your own name, your Social Security number is enough. If you have a business name different from your legal name, or if you're an LLC or corporation, you'll need an EIN — a nine-digit number the IRS issues to identify your business for tax purposes.
Next, bring proof that your business exists. For a sole proprietorship, this might be a business license from your city or county, or a DBA (Doing Business As) certificate if you registered that name. For an LLC or corporation, bring your Articles of Organization or Articles of Incorporation — the legal document you filed with your state to create the business. The bank will want to see the official copy with the state's stamp or filing date.
If anyone other than you will be signing checks or accessing the account, the bank will need their government ID and Social Security number too. Some banks require a corporate resolution — a document signed by the business owner stating who is authorized to manage the account. Smaller banks may skip this; larger ones almost always require it.
Key Takeaways
- Bring a government-issued ID and your Social Security number or EIN to prove who you are and that your business is registered.
- For an LLC or corporation, you must bring your Articles of Organization or Articles of Incorporation with the state's official stamp.
- If someone other than you will sign checks, the bank needs their ID and Social Security number, and may require a corporate resolution document.
- Sole proprietors operating under their own name need fewer documents than those using a business name or operating as an LLC.
- Call the bank before you go — document requirements vary, and some banks ask you to bring additional items like a recent utility bill or lease.
Why banks ask for these documents
Banks are required by federal law to verify the identity of anyone opening an account and to confirm that the business is real. This is part of anti-money-laundering rules that explore to every bank in the country. The bank is not being cautious for no reason — they face fines if they open accounts without proper documentation.
The documents also protect you. By requiring proof of who owns the business and who can sign checks, the bank creates a record that prevents someone else from claiming authority over your account. If a dispute arises later — a partner claims they should have been added, or an employee claims they were authorized to withdraw funds — the bank's file shows exactly what you authorized on the day you opened the account.
What to do if you don't have an EIN yet
If you're a sole proprietor using your own name, you don't need an EIN — your Social Security number works. But if you're operating as an LLC, a corporation, or a partnership, or if you're a sole proprietor using a business name and want to hire employees, you'll need an EIN before the bank will open the account.
You can get an EIN free from the IRS. The fastest way is online at irs.gov — you fill out Form SS-4 and receive your EIN when ready. You can also explore by phone (1-800-829-4933) or by mail, though mail takes several weeks. Have your Social Security number, business name, and business address ready. Once you have the EIN, the bank can proceed.
Some people wait to get an EIN until they actually need one — for example, when they hire their first employee or open a business bank account. There's no penalty for getting one early, but there's also no requirement to have one if you're a sole proprietor working alone under your own name.
Bringing your business address and ownership information
The bank will ask for your business address — where you operate or where mail should go. This can be a physical office, a home address, or a mailbox service address. You don't need to bring proof of the address (like a lease or utility bill) unless the bank specifically asks, but have it ready in case they do.
You'll also state who owns the business and in what percentage. If it's just you, that's straightforward. If there are multiple owners, the bank may ask for a list of all owners and their ownership stakes. For an LLC or corporation, this information is usually in your Articles of Organization or Articles of Incorporation, so the bank can verify it there.
What happens after you bring the documents
The bank will review everything, make copies, and verify your identity and your EIN with the IRS. This usually takes a few minutes to a few hours if you're in the branch. Some banks can do this same-day; others may take a day or two to complete the verification.
Once approved, you'll sign signature cards — documents that show the bank which people are authorized to sign checks. You may also sign an account agreement that explains the bank's fees, overdraft policies, and other terms. Read this before signing, because it governs how the account works.
The bank will give you a temporary debit card or checks, or will mail them to you. You can usually start using the account online when ready, even if your physical checks haven't arrived yet.
Differences between banks and what to ask about
Large national banks and small community banks have different document requirements. A national bank like Chase or Bank of America may require a corporate resolution and ask for additional proof of address. A community bank or credit union may be more flexible, especially if you already have a personal account there.
Before you go to the bank, call and ask what documents they need for your specific business structure. Ask whether they require a corporate resolution, whether they need proof of address, and whether there are any fees to open the account. Some banks charge a monthly maintenance fee; others waive it if you maintain a minimum balance. Knowing this in advance saves a trip.
Also ask how long verification takes and whether you can start using the account online while you wait for physical checks. Some banks let you transfer money and pay bills when ready; others make you wait until everything is verified.
If you're opening an account for a nonprofit or tax-exempt organization
Nonprofits and tax-exempt organizations follow a slightly different path. You'll need your nonprofit's Articles of Incorporation, your IRS information letter (the letter saying you're tax-exempt), and the names and IDs of the board members or officers authorized to sign checks. Some banks require a board resolution authorizing the account.
The process is similar to opening a business account, but banks are more cautious with nonprofits because they want to confirm that the organization is legitimate and that the people opening the account actually have authority. Bring everything in writing — don't rely on verbal confirmation.
Frequently Asked Questions
Can I open a business checking account online without going to the bank?
Some banks allow you to start the process online, but most require you to verify your identity in person or by video call. You'll need to show your ID and sign documents. A few online-only banks can do this entirely through video, but they're less common for business accounts than for personal accounts. Call the bank and ask whether they offer remote opening.
What if I don't have a business license yet?
For a sole proprietorship, you don't always need a business license to open a checking account — your Social Security number and proof of identity are usually enough. For an LLC or corporation, you must have filed your Articles with the state first. If you haven't done that yet, do it before you go to the bank. The filing takes a few days to a few weeks depending on your state.
Do I need a separate business address, or can I use my home?
You can use your home address as your business address. The bank doesn't require a commercial office. Just be consistent — use the same address on your business registration, your tax forms, and your bank account.
What if I'm adding a co-owner after I open the account?
You'll need to go back to the bank with the co-owner's ID and Social Security number. The bank will update the account authorization and may ask for a new signature card or corporate resolution. Some banks charge a small fee for this change; others don't. Ask when you open the account what the process is.
Can my accountant or lawyer bring the documents for me?
Most banks require at least one owner to be present in person to verify identity. Your accountant or lawyer can help you gather the documents, but you'll likely need to show up yourself with your ID. Some banks may allow a power of attorney to act on your behalf, but this is rare for account opening. Call ahead and ask.
