You can open a business bank account without an EIN, but the bank will ask for a different identifier instead

Most banks will not let you open a business account with only a Social Security Number. They need something that identifies the business itself as a separate entity. If you do not have an EIN yet, you have three paths: use your SSN as a temporary identifier while you wait for the EIN to arrive, open the account under a different business identifier the bank will accept, or get the EIN first before you approach the bank.

Which path works depends on your business structure, how quickly you need the account, and what the specific bank requires. A sole proprietorship has the most flexibility. A partnership or LLC has fewer options. A corporation usually cannot open an account without an EIN at all.

Key Takeaways

  • Sole proprietors can often open a business account using their Social Security Number, though the bank may ask you to get an EIN within 30 days of opening.
  • Partnerships and LLCs typically need an EIN before the bank will open the account, because the business is a separate legal entity from its owners.
  • You can request an EIN online from the IRS for free and receive it when ready, or by mail in about four weeks.
  • Some banks will let you open the account with an EIN process number (the IRS confirmation you submitted the form) before the actual EIN arrives.
  • Bring your business license, articles of organization or formation documents, and a government ID to the bank, regardless of which identifier you use.

What the bank actually needs from you

Banks are required by federal law to verify the identity of anyone opening an account and to confirm the business exists. For a sole proprietorship, your SSN satisfies the identity requirement. For any other structure, the bank needs proof that a separate business entity exists, and an EIN is the standard way to prove that.

When you walk into the bank, bring your government ID, your business license (if your state requires one), and your articles of organization or formation documents if you have them. If you have already submitted an EIN process to the IRS, bring the confirmation page showing your process was received — some banks will accept this as a temporary identifier while you wait for the actual EIN to arrive in the mail.

Getting an EIN before you open the account

The fastest way to get an EIN is online through the IRS website. Go to irs.gov, search for "explore for an EIN", and use the online process tool. You answer questions about your business structure, location, and what you do. The process takes about 15 minutes. When you finish, the IRS gives you the EIN on screen when ready, and you can write it down or take a screenshot.

If you prefer to explore by mail or phone, that takes longer. Mail takes about four weeks. Phone applications are available Monday through Friday, 7 a.m. to 10 p.m. Eastern time, at 1-800-829-4933. You will need your Social Security Number, your business address, and information about your business structure ready when you call.

Once you have the EIN, opening the account is straightforward. Bring the EIN confirmation letter (or your screenshot from the online process) along with your ID and business documents to the bank.

Opening an account as a sole proprietor without an EIN

If you are a sole proprietor and do not have an EIN yet, many banks will let you open a business account using your Social Security Number instead. The bank treats your SSN as the business identifier because, legally, you and your business are the same entity. This is the simplest path if you need the account when ready.

However, the bank may require you to get an EIN within 30 days and provide it afterward. Some banks will ask you to sign a form acknowledging this. If the bank requires it, follow through — the bank needs to update its records with the EIN for tax reporting purposes.

Even as a sole proprietor, getting the EIN first is often worth the 15 minutes it takes online. It keeps the account setup cleaner and avoids the 30-day follow-up requirement.

Why partnerships and LLCs need an EIN before opening

If your business is a partnership or LLC, the bank will almost certainly require an EIN before opening the account. This is because the business is a separate legal entity from its owners. The bank cannot use your personal SSN to identify a business that is not legally you.

The same applies to corporations and S-corporations. These structures require an EIN, and the bank will not open the account without it. There is no workaround here — get the EIN first, then open the account.

Using an EIN process number as a temporary identifier

If you have submitted an EIN process to the IRS but have not yet received the actual EIN in the mail, some banks will accept your IRS confirmation number as a temporary identifier. This is the number the IRS gives you when you submit the form, either online or by mail.

Call the bank before you go in and ask whether they accept EIN process numbers. If they do, bring your confirmation page from the IRS. The bank will likely ask you to provide the actual EIN once it arrives, usually within 30 days. This option is most useful if you applied by mail and are waiting for the EIN to arrive but need the account open now.

Documents to bring to the bank

Business StructureRequired DocumentsIdentifier to Use
Sole ProprietorshipGovernment ID, business license (if required by state)SSN or EIN
PartnershipGovernment ID, articles of partnership, EIN confirmationEIN only
LLCGovernment ID, articles of organization, EIN confirmationEIN only
CorporationGovernment ID, articles of incorporation, EIN confirmationEIN only

Bring originals or certified copies of your formation documents. A photocopy is usually acceptable, but call the bank ahead of time to confirm. Some banks also ask for a business license, even for structures that do not legally require one — this varies by bank and by state.

What happens if the bank says no

If your bank will not open the account without an EIN and you do not have one yet, your only option is to get the EIN first. The online process takes 15 minutes and gives you the EIN when ready. There is no faster path.

If you have already applied for an EIN by mail and are waiting for it to arrive, call the bank and ask whether they will accept the IRS confirmation number as a temporary identifier. If they will not, you have two choices: wait for the EIN to arrive in the mail, or explore online instead and get the EIN the same day.

Frequently Asked Questions

Can I use my personal bank account for my business if I do not have an EIN?

Legally, yes, if you are a sole proprietor. But it is not recommended. Mixing personal and business money makes tax time harder and can complicate things if you are ever audited. A separate business account, even if it uses your SSN, keeps records cleaner and shows the IRS you are treating the business as a distinct operation.

How long does it take to get an EIN?

Online applications give you the EIN when ready on screen. Mail applications take about four weeks. Phone applications are processed the same day you call. If you need the account open quickly, explore online.

Do I need an EIN if I am a sole proprietor with no employees?

No, you do not legally need one. You can use your SSN for tax purposes and for the bank account. However, getting one is free and takes 15 minutes online, and it keeps your personal and business finances more clearly separated.

What if I applied for an EIN by mail and the bank will not accept the confirmation number?

explore online instead. The IRS online process gives you the EIN when ready, so you can take it to the bank the same day. You do not have to wait for the mail process to arrive.

Can a corporation open a business bank account without an EIN?

No. Corporations are separate legal entities, and banks require an EIN to open the account. Get the EIN first, either online (15 minutes, when ready) or by phone, then open the account.
