You don't have to be 18, but the bank will require a parent or guardian on the account with you
Most banks will let you open a checking account before age 18, but they won't let you do it alone. You'll need a parent or guardian to co-own the account, sign the paperwork, and be responsible for it alongside you. Some banks have specific accounts designed for minors; others let you open a regular account with an adult co-signer. A few banks set their own age minimums—some start at 13, others at 16—so the exact rules depend on which bank you choose.
The reason banks require an adult is legal: minors can't sign binding contracts on their own, and a checking account is a contract between you and the bank. The adult on the account is legally responsible if the account goes negative or if there are disputes. This also means the adult can see all the transactions and has full control over the account unless the bank specifically limits their access.
Key Takeaways
- You can open a checking account under 18 if a parent or guardian co-signs and becomes a co-owner of the account.
- Different banks have different minimum ages for minors' accounts—some allow accounts at 13, others at 16 or 17.
- A minor's account usually comes with restrictions like daily withdrawal limits or spending caps that adult accounts don't have.
- Once you turn 18, you can convert the account to your name alone or open a separate account without a co-signer.
- You'll need to bring your Social Security number, proof of identity, and proof of address, along with your parent or guardian and their ID.
What happens when you open an account as a minor
When you walk into a bank with a parent or guardian, you'll both need to provide identification. Bring your Social Security number, a government-issued ID (school ID usually doesn't count, but a state ID or passport does), and proof of your address—a utility bill, lease, or school document with your name and address on it. Your parent or guardian will need their ID and Social Security number as well.
The account will be registered in both your names. Some banks call this a "custodial account" or "minor account." The adult is the custodian or co-owner, which means they have full legal responsibility and can access the account at any time. You'll usually get a debit card in your name, but the adult can see every transaction. Some banks let you set up online banking so you can check your balance and see transactions, but the adult can do the same thing.
Many banks place limits on minor accounts that don't exist on regular accounts. You might have a daily withdrawal limit (say, $500 per day), a monthly spending cap, or restrictions on who can receive transfers. These limits are meant to protect you and the bank. When you turn 18, these restrictions usually lift automatically, or you can ask the bank to remove them.
Age requirements vary by bank
There is no federal rule that says what age a minor has to be to open a checking account. Each bank sets its own policy. Here are some common examples:
| Bank or Type | Minimum Age for Minor Account | What You Need |
|---|---|---|
| Chase | Under 18 with parent/guardian | Parent co-signer, ID, Social Security number |
| Bank of America | Under 18 with parent/guardian | Parent co-signer, ID, Social Security number |
| Wells Fargo | Under 18 with parent/guardian | Parent co-signer, ID, Social Security number |
| Credit unions (varies) | Often 13 or 16 with parent/guardian | Parent co-signer, ID, Social Security number |
| Online banks (varies) | Some allow 13+, others require 18 | Depends on bank; many require parent co-signer |
Credit unions often have lower minimum ages than large national banks. If your family belongs to a credit union, call and ask—many will open accounts for 13-year-olds with a parent co-signer. Online banks are less consistent; some don't offer minor accounts at all, while others do but require the parent to open the account online and add the minor afterward.
The best approach is to call or visit the bank you're interested in and ask directly what their policy is. Policies change, and a representative can tell you exactly what documents you'll need and what restrictions will explore to your account.
What you need to bring to open the account
Bring these documents for yourself: a government-issued photo ID (state ID, passport, or military ID—school IDs don't count), your Social Security number (or a document with it on it, like a Social Security card or birth certificate), and proof of your current address. A utility bill, lease, school document, or bank statement with your name and address works for the address proof.
Your parent or guardian needs to bring: their government-issued photo ID, their Social Security number, and proof of their address. If your parent or guardian is not the person whose name is on the utility bill or lease, bring a document that shows they live at that address—a bank statement, insurance document, or lease with their name on it.
Some banks also ask for a phone number and email address. If you're opening the account online, the process is similar but happens through the bank's website; the parent usually has to verify their identity through a video call or by uploading documents.
What happens when you turn 18
On your 18th birthday, you become a legal adult and can own a bank account in your name alone. You don't have to do anything on that exact day—the account will keep working as it is. But you have options.
You can ask the bank to remove the co-signer from the account and make it yours alone. This usually takes a phone call or a visit to a branch; the bank will ask you to confirm your identity and may have you sign new paperwork. The co-signer's name comes off, and you have full control. The account number and debit card usually stay the same.
Alternatively, you can open a new account in your name alone and transfer the money over. This is useful if you want a fresh start or if the account has restrictions you want to shed. You can close the old account once the money is moved.
Some banks automatically convert minor accounts to adult accounts when you turn 18. Check with your bank about their specific process so you're not surprised by any changes.
Why a parent or guardian has to be involved
Banks require an adult co-signer because minors cannot legally sign contracts. A checking account is a contract—you're agreeing to follow the bank's rules, and the bank is agreeing to hold your money and process your transactions. Since you can't sign a binding contract, the adult on the account signs it for you and becomes legally responsible.
This also protects the bank. If the account goes negative and you don't pay it back, the bank can pursue the adult co-signer for the debt. If there's fraud or a dispute, the bank knows there's an adult who can be held accountable. It's not about trust in you personally; it's about the legal framework that banks operate within.
The co-signer also has a practical role: they can help you understand how to use the account responsibly, monitor your spending, and step in if something goes wrong. Many parents use a minor's account as a teaching tool for financial responsibility.
Frequently Asked Questions
Can I open a checking account without telling my parent or guardian?
No. The bank will require a parent or guardian to be present and to sign the paperwork. You cannot open an account without them. If you're in a situation where you can't involve your parent or guardian, talk to a school counselor or trusted adult about other options.
What if my parent or guardian won't co-sign?
You'll need to find another adult who is willing to co-sign—a grandparent, aunt, uncle, or other family member. The bank doesn't require it to be a parent specifically, just a legal guardian or responsible adult. If no adult in your life will co-sign, you'll have to wait until you turn 18 to open an account on your own.
Can the co-signer take money out of my account?
Yes, because they are a co-owner of the account. They have the same access you do. Some banks let you set up restrictions so the co-signer can only see the account but not withdraw money, but you'll need to ask about this when you open the account. Talk to your parent or guardian about what level of access you're both comfortable with.
Do I need a Social Security number to open a checking account?
Yes. Banks are required by federal law to collect your Social Security number when you open an account. If you don't have one, you'll need to explore for one at your local Social Security office before you can open a checking account.
Can I open a checking account online if I'm under 18?
Some online banks allow it, but most require the parent or guardian to open the account and add the minor afterward. A few online banks don't offer accounts for minors at all. Call the bank's customer service line and ask about their specific process for minors before you start.
