What You Need Before You Start

Union Bank requires a government-issued photo ID, a Social Security number or ITIN, and a current address to open a checking account. You'll also need an initial deposit — the amount varies by account type, but many Union Bank checking accounts have no minimum opening deposit requirement. Check the specific account you're interested in, as some products do require a deposit to start.

Have your information ready before you begin: your full legal name, date of birth, phone number, email address, and current mailing address. If you're opening an account online, you'll enter all of this into their system. If you're going to a branch in person, bring your ID and Social Security card or ITIN documentation with you.

Union Bank operates primarily in California, Idaho, Nevada, Oregon, and Washington. If you live outside these states, you won't be able to open an account with them. Check their website to confirm they serve your area before starting the process.

Opening an Account Online

The fastest way to open a Union Bank checking account is through their website. Go to unionbank.com and look for the "Open an Account" button, usually on the homepage. Select the checking account type you want — Union Bank offers several options, including basic checking and accounts with higher interest rates or additional features. Read the account details to understand any monthly fees, minimum balance requirements, or interest rates that apply.

Click through to the application and enter your personal information: full name, date of birth, Social Security number or ITIN, phone number, email, and current address. Union Bank will verify your identity during this process, which may include asking security questions based on your credit history. Answer these accurately — if the system cannot verify you, it will ask you to visit a branch in person or call their customer service line.

Once your identity is verified, review the account terms and disclosures, then sign electronically. The entire process takes about 10 to 15 minutes. You'll receive a confirmation email with your account number and temporary login credentials for online banking. Your account is usually active immediately, though you may not see it in your online dashboard for a few hours.

Opening an Account in Person at a Branch

If you prefer to open your account face-to-face, visit a Union Bank branch near you. Bring your government-issued photo ID (driver's license, passport, or state ID card) and your Social Security card or documentation showing your ITIN. You can also bring a recent utility bill or lease agreement as proof of your current address, though the branch may not require it if your ID shows your current address.

Tell the banker you want to open a checking account. They'll walk you through the account options and help you choose one that fits your needs. You'll fill out an application form (either on paper or on a tablet at the branch) with your personal information. The banker will verify your identity and may ask security questions. If you have an initial deposit ready, you can hand it over at this time — cash, check, or debit card transfer are all accepted.

The account opens on the spot. You'll receive a temporary debit card at the branch or be told when to expect it in the mail. Your permanent debit card typically arrives within 7 to 10 business days. You can start using online banking immediately with your temporary login credentials.

Opening an Account by Phone

You can also open a Union Bank checking account by calling their customer service line. The phone number is on their website — look for "Contact Us" or "Customer Service." Have your ID, Social Security number or ITIN, and current address information ready before you call.

A representative will walk you through the account options and ask you the same questions as an online or in-person application. They'll verify your identity and may ask security questions. If you pass verification, they'll open the account over the phone and provide you with your account number and temporary online banking login.

You'll need to make an initial deposit by mail, transfer, or by visiting a branch in person. The representative will explain your options. Your debit card will be mailed to you within 7 to 10 business days.

What Happens After You Apply

Your Union Bank checking account is active the same day you complete your application, whether you applied online, in person, or by phone. You can log into online banking and set up bill pay, transfer money, and check your balance immediately. However, your debit card takes longer — expect it to arrive in 7 to 10 business days.

If you made an initial deposit during the application process, it posts to your account according to Union Bank's deposit timeline. Deposits made in person at a branch are available immediately. Deposits by check or transfer may take 1 to 2 business days to clear, depending on the source.

Once your account is open, you can set up direct deposit, link external accounts for transfers, and customize your online banking settings. Union Bank offers mobile banking through their app, which you can download from the App Store or Google Play once your account is active.

Account Types and Features

Union Bank offers several checking account options. Their basic checking account typically has no monthly fee and no minimum opening deposit. Some accounts offer interest on your balance — these may have higher minimum balance requirements or monthly fees if you fall below that balance. Other accounts come with perks like cash back at ATMs, fee waivers, or higher interest rates.

Review the account comparison on Union Bank's website to see which features matter to you. Some accounts are designed for frequent travelers (with ATM fee reimbursement), while others are built for people who want to earn interest on their checking balance. The account you choose during application can usually be changed later if you decide you want different features.

Union Bank also offers joint accounts if you want to open an account with another person. Both account holders must provide their own ID and Social Security number or ITIN during the application process.

If Your Application Is Denied or Delayed

Union Bank may deny your application if they cannot verify your identity, if you have a history with ChexSystems (a banking history report system) that flags you as a risk, or if there's an issue with the information you provided. If this happens, the bank will send you a notice explaining why.

If your application is delayed, it's usually because the identity verification process needs more information. Union Bank may ask you to visit a branch in person, provide additional documentation, or answer more security questions. Check your email for any requests from the bank and respond as quickly as you can.

If you're denied, you have the right to know why. Contact Union Bank's customer service and ask for a detailed explanation. Some denials can be appealed, especially if the issue was a mistake or outdated information in your credit file. You can also try opening an account at a different bank if Union Bank's decision is final.

Frequently Asked Questions

Do I need a minimum deposit to open a Union Bank checking account?

Most Union Bank checking accounts have no minimum opening deposit requirement. However, some account types may require you to maintain a minimum balance to avoid monthly fees or to earn interest. Check the specific account details before you apply to confirm what applies to the account you want.

How long does it take to get my debit card?

Can I open a Union Bank account if I don't have a Social Security number?

Yes, you can use an ITIN (Individual Taxpayer Identification Number) instead of a Social Security number. You'll need to provide documentation of your ITIN during the application process. Contact Union Bank directly if you have questions about what documents they accept.

What if I live outside California, Idaho, Nevada, Oregon, and Washington?

Union Bank does not currently serve customers outside these five states. You'll need to open an account with a different bank that operates in your state. Many national banks like Chase, Bank of America, and Wells Fargo have branches and online services available nationwide.

Can I open a joint account with someone else?

Yes, Union Bank offers joint checking accounts. Both account holders must provide their own government-issued photo ID, Social Security number or ITIN, and current address during the application. You can open a joint account online, in person, or by phone using the same process as a single account.
