Opening a bank account is an essential step toward managing your finances. Whether you're opening your first account or switching banks, knowing exactly what documents you'll need can help you prepare and avoid any surprises.
This guide will help you prepare to open a bank account by explaining the documents you need, some additional requirements for joint accounts and minors, and what happens once you’ve opened your account.
What do you need to open a bank account?
To open a bank account, you'll need a government-issued ID, your Social Security number or ITIN, proof of address, and basic contact information. Some financial institutions may ask for an opening deposit, typically between $25 and $100, though many online accounts don't require any money upfront.
Most financial institutions also require you to be at least 18 years old, a U.S. resident, and have a valid mailing address. The documents are generally the same whether you apply online or in person, but check with your financial institution to be sure.
Here's a closer look at what you'll need to gather before you apply.
Government-issued ID
You'll generally need a government-issued ID so the financial institution can verify your identity, as required by federal law. Acceptable forms include:
Driver's license: A commonly used ID for opening accounts
Passport: Works for both domestic and international applicants
State-issued ID card: An alternative if you don't have a driver's license
Some financial institutions require two forms of ID, so check the requirements before you apply. Make sure your ID isn't expired, since many financial institutions won't accept outdated documents.
Social Security number or ITIN
If you have one, you'll provide your Social Security number when opening a bank account. If you apply online, you can simply type your number in the application without needing to show your physical Social Security card.
If you don't have a Social Security number, a financial institution may accept an ITIN instead.
Proof of address
Financial institutions typically require proof of address so your statements and alerts reach you. You'll generally need an official document with your full name and current address. Here's what qualifies:
Utility bills: Recent electric, gas, water, or internet bills
Lease agreement: Your current rental or mortgage agreement
Bank or credit card statements: Recent statements showing your address
Financial institutions typically won't accept handwritten addresses. You'll need official mail with your full name and address printed on it.
Contact information
You'll also need to provide your:
Phone number: For account alerts and verification
Email address: To access online banking and receive digital statements
Opening deposit
Some financial institutions ask for an opening deposit, which is money you add when you first set up the account. It typically ranges from $25 to $100, though many online accounts let you start with nothing. Check the specific requirements before you apply.
Extra requirements for joint accounts and minors
Joint accounts and those opened for minors need documentation from everyone listed on them. Here's what to gather for each situation.
Joint account applicants
Opening a joint account? Both account holders need to provide their:
Full legal name
Social Security number
Government-issued ID
Contact information
You may need to decide who will be the primary account holder before you apply, as some financial institutions offer this option.
Applicants under 18
If you're under 18, you'll typically need a parent or legal guardian as a co-owner. They'll usually need to provide the same documentation: full legal name, Social Security number, government-issued ID, and contact information.
Once you turn 18, you can typically request to become the sole owner of your account.
Who can open a bank account?
Most people can open an account once they meet a few basic requirements. Here's what financial institutions generally look for:
Age: You usually need to be at least 18 to open an account on your own, and younger applicants often need an adult co-owner.
Residency: Financial institutions typically require a U.S. address, and non-residents may need to provide extra documents, such as a passport or visa.
Identity verification: Financial institutions must confirm your identity before opening an account, so they check your details against public records.
Banking history: A record of unpaid overdrafts or a closed account can lead to a denial, and second-chance banking options may help if that happens.
If you have a limited banking history, you can also explore options for opening an account with bad credit.
What happens after you open a new bank account?
After you open your account, you'll generally receive your account and routing numbers along with instructions for setting up mobile banking. Here's what to do next:
Review your welcome materials: Check for details about accessing online banking, setting up direct deposit, and ordering checks.
Monitor your transactions: Review statements regularly and report any discrepancies right away.
Set up account tools: Turn on budgeting features, savings programs, and spending alerts.
Keep information current: Update your contact details if they change.
