What happens when you open a bank account

Opening a bank account means you give a bank your personal information, they verify who you are, and they create a record that lets you deposit money, write checks, use a debit card, and move money electronically. The bank holds your money in their vault or their accounts at other banks, and they pay you a small amount of interest on some account types. You get access through a debit card, online login, mobile app, or by visiting a branch.

The process takes between 15 minutes and a few days depending on whether you do it online, by phone, or in person. Most banks will let you start using the account within hours of opening it, though some transactions won't clear until the next business day. You'll need to bring or provide a government ID, proof of your address, and sometimes your Social Security number or tax ID.

Key Takeaways

  • You need a government-issued ID, proof of your current address, and usually your Social Security number to open an account at any bank.
  • Online accounts open fastest — often in 15 to 30 minutes — but in-person accounts at a branch let you ask questions and sometimes get a debit card the same day.
  • Banks check a database called ChexSystems to see if you've had problems with past accounts; some banks work with people who have a record there.
  • You can open an account with a small deposit or sometimes with no deposit at all, depending on the bank and account type.
  • If you don't have a Social Security number, some banks will open an account using an Individual Taxpayer Identification Number (ITIN) instead.

What documents and information you need to bring

Every bank requires a government-issued photo ID — a driver's license, passport, state ID card, or military ID. They scan or photograph it to verify your identity. You also need proof that you live where you say you do: a recent utility bill, lease, mortgage statement, or government mail with your name and address. Banks use this to prevent fraud and to comply with federal anti-money-laundering rules.

Most banks will ask for your Social Security number. If you don't have one, you can use an Individual Taxpayer Identification Number (ITIN), which the IRS issues to people who file taxes but don't have a Social Security number. A few banks will open accounts without either, but they may limit what you can do with the account or charge higher fees. Call ahead if you don't have a Social Security number.

Bring your initial deposit if you want to fund the account right away. Many banks have no minimum deposit requirement, but some require $25 to $100 to open. If you're opening online, you'll provide this information by typing it in and uploading photos of your documents.

Opening an account in person at a branch

Walk into a branch during business hours with your ID, address proof, and initial deposit if you have one. Tell the person at the desk you want to open a checking or savings account. They'll ask you questions about what you want the account for, how much money you expect to deposit each month, and whether you want online access. Answer honestly — they're not judging, they're matching you to the right account type.

The banker will enter your information into their system, show you the account agreement (a long document explaining the bank's rules), and ask you to sign it. They'll explain fees, interest rates, and how to use the debit card. The whole process usually takes 20 to 45 minutes. You'll walk out with a debit card or a temporary card, online login information, and an account number. You can start using the account the same day, though deposits may not clear until the next business day.

Opening an account online

Go to the bank's website, click "Open an Account" or "Sign Up", and follow the steps. You'll type in your name, address, phone number, email, and Social Security number. The bank will ask you to upload or photograph your ID and address proof using your phone or computer. Some banks use video verification — they'll ask you to show your ID to your camera and answer a few questions to confirm you're really you.

The whole process takes 15 to 30 minutes. The bank will tell you when ready whether your account is open, or they may say they need to review your information and will email you within a few hours. Once approved, you can log in, see your account number, and set up direct deposit or transfers. A physical debit card arrives by mail in 7 to 10 business days, though many banks let you use a temporary digital card in their app right away.

What ChexSystems is and why banks check it

ChexSystems is a database that banks use to check whether you've had problems with past accounts. If you've overdrawn an account, written bad checks, or committed fraud, that information goes into ChexSystems. Banks check it before opening a new account. If you're in the system, some banks will deny you. Others will open an account but charge higher fees or limit your access to certain features.

You can request a free copy of your ChexSystems report from the company's website (chexsystems.com) to see what's there. If information is wrong, you can dispute it. If you're in the system and want to open an account, look for banks that advertise "second chance" checking accounts — they specifically work with people who have a ChexSystems record. Credit unions sometimes have more flexible policies than large banks.

Fees and minimum balances to watch for

Banks make money partly from fees. Common ones are monthly maintenance fees (usually $5 to $15), overdraft fees (charged when you spend more than you have), ATM fees (if you use another bank's ATM), and fees for paper statements or wire transfers. Some accounts have no monthly fee at all. Online banks tend to charge fewer fees than branches because they have lower costs.

Minimum balance requirements vary. Some accounts require you to keep $500 or $1,000 in the account at all times or you'll be charged a fee. Others have no minimum. If you're opening your first account or don't have much money to start with, look for accounts with no minimum balance and no monthly fee. Read the fee schedule before you sign — it's usually a page in the account agreement.

Getting your debit card and setting up online access

If you open in person, you may get a debit card the same day or within a few days. If you open online, the card arrives by mail in 7 to 10 business days. Before you use it, you'll need to set up it — the bank will send you a text or email with instructions, or you'll set up it in the mobile app or by calling a number on the card.

Online access means you can log in to the bank's website or app to check your balance, transfer money, pay bills, and deposit checks by taking a photo. You'll create a username and password. Many banks also offer two-factor authentication — they'll text you a code when you log in from a new device, which makes your account more find. Set this up as soon as you can.

Frequently Asked Questions

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

Yes. You can use an Individual Taxpayer Identification Number (ITIN) instead, which the IRS issues to people who file taxes but don't have a Social Security number. Some banks accept ITIN; others don't. Call the bank before you go in or check their website to confirm they'll open an account with an ITIN.

What if I'm denied when I try to open an account?

Banks usually deny accounts because of a ChexSystems record, unpaid overdrafts at another bank, or fraud concerns. Ask the bank why you were denied — they're required to tell you. If it's a ChexSystems issue, look for a "second chance" checking account at another bank or a credit union. If it's unpaid overdrafts, pay them first, then try again.

How long does it take to use my account after I open it?

You can usually start using your account within hours of opening it online or in person. Deposits you make may not clear until the next business day. If you open online, your debit card arrives by mail in 7 to 10 days, but most banks let you use a digital card in their app right away.

Do I need to keep a minimum balance in my account?

It depends on the account. Some accounts require you to keep $500 or $1,000 or you'll be charged a fee each month. Many accounts, especially online ones, have no minimum balance requirement. Check the fee schedule before you open to see whether the account you want has a minimum.

Can I open more than one account at the same bank?

Yes. You can open a checking account and a savings account at the same bank, or multiple accounts of the same type if you want to separate money for different purposes. Each account has its own number and debit card (if it's a checking account). There's no limit to how many accounts you can have.
