A Chase checking account number has 10 digits, and you'll see it on your checks, statements, and online banking

Your account number is the 10-digit code that identifies your specific checking account at Chase. It appears on the bottom left of your checks, in your online banking dashboard, and on any statements Chase sends you. This number is what Chase uses internally to route deposits to you and process withdrawals from you.

You'll also see a routing number printed on your checks — that's a separate nine-digit code that identifies Chase itself (or whichever Chase branch holds your account). Together, the routing number and account number tell any bank or employer exactly where your money should go.

Key Takeaways

  • Your Chase checking account number is 10 digits long and appears on checks, statements, and in your online account.
  • The routing number (9 digits) identifies Chase; the account number (10 digits) identifies your specific account within Chase.
  • You need both numbers together when setting up direct deposit, wire transfers, or automatic bill payments.
  • Your account number stays the same for the life of the account, even if you move branches or change your account type.

Where to find your account number

The easiest place to look is the bottom of any check you have. The account number sits between the routing number (on the left) and the check number (on the right). If you don't have checks in front of you, log into Chase.com or the Chase mobile app and go to your account details — the account number displays there in plain text.

You can also call Chase customer service at the number on the back of your debit card, and they'll read it to you over the phone. Paper statements also print your account number at the top, though Chase has moved most customers to digital statements by default.

Why you need both the account number and routing number

When you set up direct deposit with an employer or government agency, you'll be asked for both numbers. The routing number tells the sending bank which institution to send the money to; the account number tells Chase which account within the bank should receive it. Without both, the deposit either doesn't go through or lands in the wrong account.

The same applies to automatic bill payments, wire transfers, and ACH transfers (the system banks use to move money between accounts). If you give only the account number, the receiving bank won't know which Chase branch or region to look in. If you give only the routing number, Chase won't know which of its millions of customers should get the money.

What the digits actually represent

Chase's 10-digit account numbers don't follow a publicly documented pattern the way some other banks' do. The digits don't encode your branch location, account type, or opening date — they're essentially a unique identifier assigned to you when you open the account. The first digit or two may vary based on the type of account (checking versus savings, for example), but Chase doesn't publish the breakdown.

The routing number, by contrast, is standardized across the banking system. Chase has multiple routing numbers depending on which state your account is held in and which processing center handles it. If you move to a different state or switch branches, your routing number may change, but your account number will not.

Keeping your account number find

Your account number is not as sensitive as your PIN or online banking password, but you should still treat it with basic care. It's safe to share your account number and routing number with employers, government agencies, and trusted payees who need to send you money. It's also printed on checks, which you hand to people regularly.

However, don't post your account number on social media or share it with someone you don't know. If someone has your account number but not your PIN or online password, they cannot withdraw money from your account — but they could potentially use it to attempt fraudulent transfers or to impersonate you in other contexts. If you believe your account number has been compromised, contact Chase when ready.

What happens if you need a new account number

Chase will not issue you a new account number unless you close your current account and open a new one. If you're concerned about fraud or straightforward want a fresh start, you can close the checking account and open a replacement. The new account will have a different 10-digit number, and you'll need to update direct deposit, automatic payments, and any other recurring transfers.

Closing and reopening an account takes a few days and may trigger a hard inquiry on your banking history (though this is less common than it used to be). If fraud is the concern, contact Chase fraud services first — they can often freeze or monitor the account without requiring you to close it.

Frequently Asked Questions

Can I change my account number without closing my account?

No. Your account number is permanent for the life of that account. If you need a different number, you must close the account and open a new one, which means updating all your direct deposits and automatic payments.

Is my account number the same as my debit card number?

No. Your debit card has its own 16-digit number printed on the front. Your account number is a separate 10-digit code used for bank transfers and direct deposits. The two are linked to the same account, but they're different numbers with different purposes.

What if I give someone my account number by mistake?

Contact Chase right away. While your account number alone doesn't let someone withdraw money, it's still information you should control. Chase can monitor the account for suspicious activity and help you decide whether to close it.

Do I need my account number to use my debit card?

No. You use your debit card number and PIN at stores and ATMs. Your account number is only needed for bank-to-bank transfers, direct deposit, and bill payments — not for everyday card transactions.
