Yes, you can open most BMO accounts online in minutes

BMO lets you open a checking or savings account entirely online through their website or mobile app. The process takes about 10 to 15 minutes and requires a valid government ID, Social Security number, and initial deposit (which varies by account type). You'll have access to your account and debit card within one to two business days in most cases, though the physical card itself arrives by mail in five to seven business days.

Not every BMO account type is available online. Some specialty accounts, business accounts, and accounts requiring a minimum deposit above a certain threshold may require you to visit a branch or call. Before you start, check which specific account you want — BMO offers checking, savings, money market, and certificate of deposit (CD) accounts, each with different online availability and requirements.

Key Takeaways

  • BMO checking and savings accounts can be opened online through their website or app with just an ID, Social Security number, and an initial deposit.
  • The entire process takes 10 to 15 minutes, and you can use your account immediately, though your physical debit card arrives by mail.
  • You must be at least 18 years old and a U.S. resident with a valid Social Security number to open an account online.
  • Some account types, including business accounts and certain high-minimum products, require you to visit a branch or call instead of opening online.

What you need before you start

Gather these items before opening your account: a valid government-issued photo ID (driver's license, passport, or state ID), your Social Security number, and your current address. You'll also need to decide on an initial deposit amount — most BMO checking accounts require a minimum opening deposit, though the amount varies. Check BMO's current terms for the specific account you want, as minimums change.

Have your phone or computer ready with a stable internet connection. BMO's online process works on both desktop and mobile, but you'll need to verify your identity, which sometimes involves taking a photo of your ID or answering security questions. If you're opening an account linked to an existing BMO account, have that account number handy.

The step-by-step process

Start at BMO's website or open their mobile app and select "Open an Account." Choose the account type you want — checking, savings, money market, or CD. BMO will ask you to enter your personal information: full name, date of birth, address, phone number, and email. You'll create a username and password for online banking access.

Next, BMO verifies your identity. This usually means uploading a photo of your government ID or answering questions based on your credit history. The verification happens in real time or within a few minutes. Once verified, you'll review the account terms and conditions, agree to them, and set up your initial deposit method — either from another bank account or a debit card.

After you submit, BMO sends a confirmation email with your account number and temporary access details. You can log into online banking immediately and set up bill pay, transfers, and other services. Your debit card ships separately and typically arrives within five to seven business days.

When you cannot open an account online

BMO requires you to visit a branch or call if you're opening a business account, applying for a secured credit card, or need a product with a minimum deposit above a certain threshold. Some specialty accounts tied to specific programs also require in-person verification. If you're under 18, you'll need a parent or guardian to open a joint account at a branch.

If your identity verification fails online — for example, if your ID photo is unclear or your information doesn't match BMO's records — you'll be asked to visit a branch with your original ID. This is also the case if you don't have a Social Security number or are not a U.S. resident, though BMO may have alternative accounts for non-residents; contact them directly to ask.

How long until you can use your account

Your account is active immediately after you complete the online process. You can log into online banking, set up bill pay, and transfer money between your own accounts right away. However, if you're transferring money from another bank to fund your initial deposit, that transfer follows standard ACH timelines — usually one to two business days.

Your debit card arrives by mail in five to seven business days. Until it arrives, you can use your account number and routing number to receive direct deposits or set up automatic payments. If you need a card sooner, some BMO branches can issue a temporary card or expedite shipping for a fee; call or visit a branch to ask about this option.

Fees and account requirements after opening

BMO checking accounts may have monthly maintenance fees, though some accounts waive the fee if you maintain a minimum balance or set up direct deposit. Savings accounts typically have no monthly fee but may charge if you exceed a certain number of withdrawals per month. Review the fee schedule for your specific account type before opening, as fees vary.

After opening, you're responsible for keeping your account in good standing: maintaining any required minimum balance, following withdrawal limits on savings accounts, and reporting any unauthorized transactions within 60 days. BMO also requires you to keep your contact information current and monitor your account for fraud.

Frequently Asked Questions

Do I need an existing BMO account to open a new one online?

No. You can open your first BMO account entirely online without any prior relationship with the bank. However, if you already have a BMO account, linking it during the process can speed up funding and verification.

What if my identity verification fails?

If BMO cannot verify you online, you'll receive an email explaining why. Common reasons include a blurry ID photo, mismatched information, or a name that doesn't match your credit file. You can usually fix this by visiting a branch with your original ID or calling BMO to complete verification over the phone.

Can I open an account if I have a bad banking history?

BMO checks your banking history through ChexSystems, a banking verification system. If you're listed for unpaid fees or fraud, you may be denied. However, some banks offer second-chance accounts; contact BMO directly to ask if you're unsure whether you'll be approved.

How do I fund my account after opening it online?

You can transfer money from another bank account (takes one to two business days), deposit a check using mobile deposit once your debit card arrives, or visit a branch to deposit cash. Your initial deposit can come from a debit card or linked bank account during the online signup process.

Can I close my account if I change my mind?

Yes. You can close your BMO account online through your banking portal or by calling customer service. Make sure your account balance is zero and all pending transactions have cleared before closing. BMO may charge a fee if you close the account within a certain timeframe; check your account terms.
