Minimum age requirements vary by bank, but most require you to be at least 18

You must be 18 years old to open a checking account in your own name at most banks. This is the legal age of majority in the United States, which means you can sign contracts and enter into binding agreements with financial institutions.

Some banks set their minimum age higher — a few require 21 — so it is worth checking your specific bank's policy before you visit a branch or start an online application. The age requirement is set by the bank itself, not by federal law, which is why it varies.

If you are under 18, you have two main paths: open a joint account with a parent or guardian, or wait until you turn 18 to open an account on your own.

Key Takeaways

  • Most banks require you to be 18 to open a checking account by yourself, though a few require 21.
  • If you are under 18, you can open a joint account with a parent or guardian at nearly every bank.
  • A joint account lets you use a debit card and write checks, but the parent or guardian can see all transactions and withdraw money.
  • Some banks offer teen checking accounts designed for minors, which come with parental controls and spending limits.
  • You will need a Social Security number and a form of ID to open any account, whether you are 18 or older.

Joint accounts for people under 18

If you are younger than 18, you can open a joint checking account with a parent, guardian, or sometimes a grandparent. The adult becomes a co-owner and can manage the account alongside you. Most major banks — Chase, Bank of America, Wells Fargo, Ally, and others — offer this option.

A joint account works like a regular checking account: you get a debit card, can write checks, and can set up direct deposit. The key difference is that the adult on the account can see every transaction, set spending limits, and withdraw money at any time. This is by design — the account is meant to help you learn to manage money while the adult maintains oversight.

To open a joint account, you and the adult will both need to visit a branch or complete an online application together. You will need your Social Security number, a form of ID (school ID or state ID often works), and the adult will need their ID and Social Security number as well.

Teen checking accounts with parental controls

Some banks offer accounts specifically designed for minors, often called teen checking or youth accounts. These accounts come with built-in parental controls: the parent can set daily spending limits, receive alerts when the teen uses the card, and restrict certain types of transactions.

Banks that offer teen accounts include Chase (Chase First Banking), Bank of America (BankAmericard for Students), and Ally (Ally Bank Teen Checking). The age range varies — some start at 13, others at 15 or 16. The parent does not need to be a co-owner; instead, they manage the account through a separate app or portal.

Teen accounts typically come with a debit card and online banking access, but usually not check-writing privileges. Monthly fees are often waived if you meet certain conditions, such as setting up direct deposit or maintaining a minimum balance.

What you need to bring to open an account

Whether you are 18 or opening a joint account as a minor, you will need the same documents. Bring your Social Security number and a form of ID. For adults, this is usually a driver's license or passport. For minors, a school ID, state ID, or passport works at most banks.

You will also need proof of address if you are opening the account online or by mail — a utility bill, lease, or bank statement with your name and current address. If you are opening a joint account, the adult will need to bring their ID and Social Security number as well.

Some banks ask for a phone number and email address during the application. A few may ask about your employment or income, though this is less common for checking accounts than for credit products.

Opening an account online versus in person

Most banks let you open a checking account online, and the process is the same whether you are 18 or older. You enter your personal information, upload photos of your ID and proof of address, and agree to the account terms. The account usually opens within one to three business days.

If you are under 18 opening a joint account, some banks require you to visit a branch in person so the adult can sign the account agreement. Others allow the adult to sign electronically. Call your bank or check their website to find out which option they use.

Opening in person at a branch takes longer — you may wait 30 minutes to an hour — but you can ask questions and get help on the spot. Online opening is faster but requires you to navigate the process yourself and upload documents correctly.

What happens when you turn 18

If you opened a joint account as a minor, you do not automatically become the sole owner when you turn 18. The account remains joint unless you and the adult take steps to change it. Some people keep the joint account because they want the adult to continue monitoring their spending or helping them manage money.

If you want to remove the adult from the account, you will need to contact the bank. Some banks let you do this online; others require you to visit a branch or call. The adult may need to sign off on the change, depending on the bank's policy. Once the adult is removed, you become the sole owner and they can no longer see transactions or withdraw money.

Alternatively, you can open a new account in your name alone and transfer your money over. This is sometimes simpler than removing a co-owner, especially if you want a fresh start.

Frequently Asked Questions

Can I open a checking account at 17 if I turn 18 soon?

No — banks enforce the age requirement on the day you open the account, not on the day it becomes active. If you are 17, you will need to wait until your 18th birthday or open a joint account with an adult. Some banks may let you start an application before your birthday and complete it on the day you turn 18.

Do I need a parent's permission to open an account at 18?

No. At 18, you are a legal adult and can open a checking account on your own without anyone's permission or signature. You do not need to tell your parents, and they will not be able to see your transactions unless you add them as a co-owner.

What if I do not have a Social Security number?

You will need a Social Security number to open a checking account at a U.S. bank. If you are not a U.S. citizen, some banks accept an Individual Taxpayer Identification Number (ITIN) instead. Call your bank to ask whether they accept ITIN or what alternatives they offer.

Can a grandparent open a joint account with me instead of a parent?

Yes, most banks allow any adult to open a joint account with a minor, not just parents. A grandparent, aunt, uncle, or older sibling can serve as the co-owner. The bank's requirements are the same — the adult needs ID and a Social Security number.

Will opening a checking account affect my credit score?

No. Opening a checking account does not affect your credit score because banks do not report checking accounts to credit bureaus. Credit scores are based on credit activity — loans, credit cards, and payment history — not on deposit accounts.
