Documents and identification you'll need to provide

To open a joint checking account, both account holders must provide a government-issued photo ID — a driver's license, passport, or state ID card. The bank needs to verify that both people are who they say they are before the account exists. Bring the original ID, not a copy, because the bank will scan or photograph it during the application process.

You'll also need a Social Security number or Individual Taxpayer Identification Number (ITIN) for each person on the account. The bank uses this to run a background check through ChexSystems or Early Warning Services, which are banking verification systems that flag fraud risk or unpaid overdrafts at other banks. If either account holder has been flagged in these systems, the bank may deny the account or require additional steps before opening it.

Bring proof of your current address — a utility bill, lease, mortgage statement, or government mail dated within the last 60 days. Some banks accept a bank statement instead. If you've moved recently and your ID doesn't match your current address, bring both the old ID and the new address proof.

Key Takeaways

  • Both account holders must bring a government-issued photo ID and provide their Social Security number or ITIN in person or online.
  • The bank will run a background check through ChexSystems or Early Warning Services to verify neither person has unpaid overdrafts or fraud flags at other banks.
  • You'll need proof of your current address, such as a utility bill or lease dated within the last 60 days.
  • Some banks allow one person to open the account online and add the second person later, while others require both to be present or to sign documents separately.
  • If either person has been denied a bank account before, contact the bank ahead of time to ask what additional documentation they may need.

How the bank verifies your information

When you submit your ID and Social Security number, the bank queries ChexSystems or Early Warning Services — the two major banking history databases. These systems track overdrafts, fraud reports, and closed accounts due to mismanagement. If you or your co-account holder appear in either system, the bank will see a flag and may ask follow-up questions or deny the account outright.

The bank also runs a soft credit pull, which does not affect your credit score. This is different from a hard inquiry; it's a background check, not a loan decision. The bank is checking whether you have a history of unpaid debts or fraud, not whether you may have access to for credit.

If either account holder has been flagged, ask the bank what specific issue triggered the flag. Some flags expire after a set period — typically five to seven years — and some can be removed if you pay off the underlying debt. If you know you have a flag, bring documentation showing the issue has been resolved, such as a letter from a previous bank confirming you paid an overdraft.

Whether both people need to be present

This varies by bank and by whether you're opening the account in person or online. Some banks require both account holders to be physically present at a branch with ID in hand. Others allow one person to open the account online and add the second person as a signer later, though the second person will still need to verify their identity before they can access the account or make transactions.

If you're opening online, the bank will typically send a secure link to both email addresses. Each person clicks the link, uploads their ID, and confirms their Social Security number. Some banks then mail a PIN or verification code to each person's address on file, which they must enter to activate the account.

Call the bank before you start the application and ask their specific process. If one person is out of state or unavailable, knowing whether you can complete the application separately saves time and frustration.

Initial deposit requirements

Most banks require a minimum opening deposit to activate a joint checking account. This amount varies widely — some banks require as little as $25, while others require $100, $500, or more. A few banks have no minimum deposit requirement at all. The opening deposit can come from either account holder or split between both.

You can fund the account by transferring money from another bank account, depositing a check, or making a cash deposit at a branch. If you're opening the account online, you'll typically provide the routing and account number of an existing bank account to transfer the opening deposit electronically. The transfer usually takes one to three business days to clear.

Ask the bank whether the opening deposit counts toward any monthly balance requirement. Some accounts require you to maintain a minimum balance to avoid a monthly fee; others charge a fee regardless. Knowing this upfront helps you decide whether the account is worth opening.

Paperwork both account holders must sign

Both people must sign the account agreement and disclosure documents, which outline the terms of the account, fee structure, and each person's rights and responsibilities. If you're opening in person, you'll both sign these documents at the branch. If you're opening online, you'll both sign electronically using an e-signature tool, and the bank will email you copies for your records.

The account agreement specifies whether the account is a true joint account — meaning both people own all the money and either can withdraw it — or a convenience account where one person is the primary owner and the other is an authorized signer. This distinction matters if one account holder dies or if the relationship ends. Ask the bank to explain the difference before you sign, because changing it later can be complicated.

You'll also receive disclosures about overdraft protection, fraud liability, and how the bank handles disputes. Read these carefully, especially the section on what happens if one account holder disputes a transaction or if the account is frozen due to a legal hold.

What happens if one person is denied

If the bank denies the account because of a ChexSystems flag on one person's record, that person has the right to request a copy of their ChexSystems report and dispute any errors. You can order your report directly from ChexSystems' website at no cost. If there's an error — for example, an overdraft that was actually paid — you can file a dispute with ChexSystems, which will investigate and correct the report if the dispute is valid.

If the denial is based on fraud or an unresolved overdraft, the person flagged will need to resolve that issue before most banks will open an account. This might mean paying the overdraft, waiting for the flag to age off the system, or applying at a bank with less restrictive policies, such as a credit union or online bank.

Some banks offer second-chance checking accounts designed for people with banking history issues. These accounts often come with higher fees and lower limits on debit card transactions, but they're a way to rebuild banking history. Ask the bank whether they offer this option if you're denied a standard joint account.

Frequently Asked Questions

Can we open a joint account if we're not married?

Yes. Banks do not require marriage or any legal relationship to open a joint account. You can open one with a family member, friend, business partner, or anyone else. Both people just need to provide ID and a Social Security number.

What if one person doesn't have a Social Security number?

If one person has an ITIN (Individual Taxpayer Identification Number) instead of a Social Security number, most banks will accept it. Bring the ITIN documentation along with the ID. If the bank won't accept an ITIN, ask whether they offer accounts for non-citizens or whether a credit union in your area has different policies.

Do we both have to sign the paperwork, or can one person sign for both?

Both people must sign. The bank needs each person's signature to confirm they understand the account terms and agree to be bound by them. One person cannot sign on behalf of the other.

How long does it take to open a joint account?

If you open in person at a branch, the account is usually active the same day or within one business day. If you open online, it typically takes one to three business days for the account to be fully activated and for both people to gain access. Some banks mail a debit card, which adds another five to seven business days.

What if we already have separate accounts at the same bank — do we need new IDs?

No. If the bank already has your ID and Social Security number on file from an existing account, they may not need you to provide them again. However, the co-account holder will still need to provide their ID and Social Security number, since they're new to the bank or new to that account.
