Chase account numbers are 10 digits long
Your Chase bank account number is always 10 digits. You'll find it on the bottom left of your checks, in your online banking dashboard, or by calling Chase customer service. The account number itself never changes for the life of that account.
When you see your full account information printed or displayed, it appears as a 10-digit string with no letters or special characters. This is different from your routing number (which is 9 digits and identifies which Chase branch or processing center handles your account) and your card number (which is 16 digits for debit or credit cards).
Key Takeaways
- Chase account numbers are exactly 10 digits long, with no letters or symbols.
- You can find your account number on checks, in the Chase mobile app, online banking, or by calling customer service.
- Your account number stays the same for as long as you keep that account open.
- When setting up direct deposit or wire transfers, you'll need both your 10-digit account number and your 9-digit routing number.
Where to locate your Chase account number
The easiest place to find your account number is on a check. Look at the bottom of the check: the first set of numbers on the left is your routing number (9 digits), and the second set is your account number (10 digits). The third set is your check number.
If you don't have checks handy, log into your Chase online banking account or open the Chase mobile app. Your account number appears in the account details section, usually labeled "Account Number" or visible when you select the specific account. You can also call Chase customer service at the number on the back of your debit card, and a representative will read it to you over the phone.
Why you need both your account number and routing number
Your account number identifies which specific account you have at Chase. Your routing number identifies which Chase location or processing center handles transactions for that account. Together, they form a complete address for your money.
When you set up direct deposit from an employer, arrange a wire transfer, or authorize an automatic payment, you'll be asked for both numbers. Giving only one is not enough—the receiving bank needs both to send money to the right place. If you provide the wrong account number but the correct routing number, the money may go to someone else's Chase account, or the transaction may be rejected.
What happens if you give out your account number
Sharing your 10-digit account number alone is generally low-risk. Your account number by itself does not allow someone to withdraw money or make purchases. To actually move money out of your account, a person would also need your routing number, and even then they would typically need authorization or additional verification from Chase.
The real risk comes when you share your account number along with other information—your name, routing number, and especially your online banking password or PIN. If someone has all of these, they may be able to set up unauthorized transfers or payments. If you suspect fraud, contact Chase immediately at the number on your statement or debit card. Chase monitors accounts for suspicious activity and can freeze or reverse unauthorized transactions.
Account numbers stay the same when you change account types
If you switch from a checking account to a savings account, or consolidate accounts, Chase may close your old account and open a new one with a different 10-digit number. However, as long as you keep the same account open, the number never changes. You don't need to update direct deposit or automatic payments unless you actually close the account.
If Chase closes your account (for inactivity, at your request, or due to policy violations), any new account you open will have a completely different 10-digit number. This is why it's important to update your direct deposit information with your employer if you ever close and reopen an account.
How account numbers work with other Chase products
Your Chase checking or savings account number is separate from your Chase credit card number, Chase business account number, or any other Chase product you may have. Each one has its own identifier. If you have multiple Chase accounts, each one has its own unique 10-digit account number.
When you link accounts together in online banking (for example, to transfer money between your checking and savings), Chase uses these separate account numbers to route the money correctly. The routing number stays the same across all your Chase accounts at the same branch, but each account has its own 10-digit number.
Frequently Asked Questions
Can I change my Chase account number?
No. Your account number is permanent for that account. If you need a different number, you would have to close the account and open a new one, which would give you a new 10-digit number. Chase does not reassign or change account numbers on active accounts.
Is my 10-digit account number the same as my debit card number?
No. Your debit card number is 16 digits and is different from your account number. The account number identifies your bank account; the card number identifies the physical or digital card linked to that account. You can have the same account number with multiple debit cards.
What if I only have a Chase credit card and no checking account?
Credit cards don't have account numbers in the same way checking accounts do. Your credit card has a 16-digit card number, which is different. If you want a 10-digit account number, you need to open a Chase checking or savings account.
Do I need my account number to log into online banking?
No. You log in with your username and password or through the Chase app. Your account number is not a login credential. However, Chase may ask you to verify your account number as part of security checks or when you call customer service.
