What banks ask for when you walk in

Most banks need two things to open a checking account: a government-issued photo ID and a Social Security number or ITIN. That's the baseline. Beyond that, what they ask for depends on the bank, whether you're opening in person or online, and sometimes on your banking history.

The photo ID has to be current and show your face—a driver's license, passport, or state ID card all work. If you don't have one, some banks will accept other documents like a tribal ID or military ID. The Social Security number or ITIN goes into their system so they can run a background check and report the account to the IRS. If you don't have either, a few banks will still open an account for you, but they'll ask more questions and may limit what you can do.

Banks also run a check through ChexSystems or Early Warning Services, which are databases that track banking problems like unpaid overdrafts or fraud. If you've had trouble at another bank, this check might flag it. That doesn't automatically disqualify you—many banks will still open an account—but some will decline or ask you to wait a certain amount of time before trying again.

Key Takeaways

  • You need a current government photo ID and a Social Security number or ITIN to open a checking account at most banks.
  • Banks check ChexSystems or Early Warning Services to see if you've had problems at other banks, but a past issue usually doesn't block you from opening an account.
  • Online banks often need less paperwork than brick-and-mortar branches, but they may require a linked external bank account to fund your new account.
  • If you don't have an ID or Social Security number, credit unions and some community banks are more likely to work with you than large national chains.
  • Your opening deposit can be as little as $0 at many banks, though some require a minimum to avoid monthly fees.

Opening in person versus online

Opening an account at a physical branch takes about 15 to 30 minutes. You bring your ID and Social Security card (or a document with your number on it), sign some paperwork, and often make a deposit on the spot. The teller can answer questions about fees, overdraft policies, and how to use the debit card. If something doesn't match up—your address on file, your name spelling, your ID expiration—they can fix it right there.

Opening online is faster but requires you to have more ready beforehand. You'll upload photos of your ID and sometimes a second document like a utility bill or bank statement to prove your address. You'll enter your Social Security number directly into the bank's website. Most online banks ask you to link an existing bank account so they can verify you're real by sending you two small deposits and asking you to confirm the amounts. This verification step can take three to five business days.

Online banks generally need less paperwork overall, but they can't answer questions in real time the way a branch can. If you're new to banking or unsure about fees and features, opening in person might be worth the trip.

Documents that help but aren't always required

A second form of ID speeds things up. A passport, military ID, or state ID card works if your driver's license is expired or you don't have one. Some banks ask for a second document to prove your address—a recent utility bill, lease, mortgage statement, or government mail with your name and current address on it. This is more common when you're opening online, but some branches ask for it too.

If you're opening an account for a minor, you'll need to bring the child's birth certificate or Social Security card and your own ID. You'll be listed as the account holder or custodian, depending on the bank's policy. Some banks let minors have their own account at a certain age; others require a parent or guardian to stay on the account.

If you've been through a name change—marriage, divorce, or legal name change—bring a document that shows both your old name and new name, like a marriage certificate or court order. This prevents the bank from flagging your account as suspicious when records don't match.

What happens if you don't have an ID or Social Security number

Large national banks will usually turn you away if you can't provide a Social Security number or ITIN. Credit unions and smaller community banks are more flexible. Some will open an account using an ITIN, a passport number, or even just a state ID number if you can't get a Social Security number. A few will open an account without any of these if you bring multiple forms of ID and proof of address.

If you're undocumented or don't have a Social Security number yet, call ahead to the bank or credit union you're considering. Ask specifically whether they work with people who have an ITIN or no Social Security number. Don't assume they won't—many do, but their policies vary widely.

Some banks offer "second chance" checking accounts for people who have been denied elsewhere or have a negative ChexSystems report. These accounts often come with higher fees and lower limits on how much you can deposit or withdraw, but they're designed to get you back into the banking system.

Minimum deposits and opening fees

Most banks don't require a minimum deposit to open a checking account—you can open with $0. However, some banks waive monthly maintenance fees only if you keep a certain balance, make a certain number of deposits, or set up direct deposit. Read the fee schedule before you open so you know what you're signing up for.

A few banks charge an opening fee of $25 to $50, though this is less common than it used to be. Online banks almost never charge opening fees. If a bank charges one, ask whether they'll waive it if you set up direct deposit or keep a minimum balance.

Monthly maintenance fees range from $0 to $15 depending on the bank and account type. Many banks waive the fee if you maintain a minimum balance (often $500 to $1,500), receive direct deposit, or make a certain number of debit card transactions per month. Some banks don't charge a monthly fee at all.

What banks check before they say yes

Banks run your name and Social Security number through ChexSystems or Early Warning Services. These databases show whether you've had accounts closed due to overdrafts, fraud, or other problems. If you show up in the system, the bank will see how long ago the problem was and what it was. A closed account from five years ago is treated differently than one from last month.

Banks also run a soft credit check, which doesn't affect your credit score. This check looks for signs of fraud or identity theft, not whether you pay your bills on time. If your credit report shows you've been a victim of identity theft, the bank might ask more questions or require extra verification.

Some banks decline accounts based on ChexSystems reports, but many don't. If you've had problems before, be honest about it when you open your account. Some banks will work with you if you explain what happened and show you've fixed the problem.

Bringing everything together: a checklist

Before you go to the bank or start an online application, gather these items:

  • A current government-issued photo ID (driver's license, passport, or state ID)
  • Your Social Security number or ITIN
  • A second form of ID if your first one is expired or you want to speed up the process
  • Proof of your current address (utility bill, lease, or recent bank statement) if opening online or if the bank asks for it
  • Information about your employer or income source if you plan to set up direct deposit
  • The name and account number of another bank account if you're opening online and the bank requires verification

If you're opening an account for a minor, bring the child's birth certificate or Social Security card and your own ID. If you've had a name change, bring the document that shows both names.

Frequently Asked Questions

Can I open a checking account without a Social Security number?

Large banks typically require a Social Security number or ITIN. Credit unions and community banks are more likely to work with you if you have an ITIN or other government ID. Call ahead to ask whether the bank you're considering will open an account without a Social Security number.

What if I've been denied a checking account before?

If you show up in ChexSystems with a negative report, many banks will still open an account for you, especially if the problem was years ago. Some banks specialize in "second chance" accounts. If you're declined, ask the bank why and how long you need to wait before trying again. You can also request your ChexSystems report to see what's on file.

Do I need to bring my Social Security card to the bank?

No. You need to provide your Social Security number, but you can do that verbally or by typing it into an online form. Bringing your card isn't necessary and some people prefer not to carry it. A utility bill or other document with your number on it works too.

How long does it take to open a checking account?

In person, 15 to 30 minutes. Online, it can be instant, but verification through linked bank accounts takes three to five business days before you can use the account fully. Some online banks let you start using the account right away and complete verification later.

What's the difference between opening at a big bank and a credit union?

Big banks have more branches and ATMs but often charge higher fees and have stricter requirements. Credit unions typically have lower fees and are more flexible about who they'll open an account for, but they have fewer locations. Both require the same basic documents.
