Chase checking accounts use a 10-digit account number
Your Chase checking account number is 10 digits long. You'll find it on the bottom left of your checks, in your online banking portal, or by calling Chase customer service. This number is unique to your specific account and is separate from your routing number, which identifies Chase itself rather than your individual account.
The 10-digit format is standard across most major U.S. banks, though some regional banks use different lengths. Chase uses this consistently whether you have a basic checking account, a premium account like Chase Premier Plus, or a business checking account.
Key Takeaways
- Your Chase checking account number is always 10 digits and appears on the bottom left of your checks, starting after the routing number.
- The routing number (9 digits) and account number (10 digits) are two separate identifiers you need for wire transfers and direct deposits.
- You can find your account number in the Chase mobile app, online banking dashboard, or by calling 1-800-935-9935.
- Never share your full account number with anyone except Chase or a business you are directly paying, as it can be used to set up unauthorized transfers.
Where to find your 10-digit account number
The easiest place to locate your account number is on a check. Look at the bottom of the check: you'll see three sets of numbers. The first set (9 digits) is your routing number. The second set (10 digits) is your account number. The third set is the check number itself.
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 visible on your dashboard or in account settings. You can also call Chase at 1-800-935-9935 and speak with a representative who can confirm your account number over the phone.
The difference between routing number and account number
Many people confuse these two numbers because they appear together on checks, but they serve different purposes. Your routing number (9 digits) identifies Chase Bank itself and tells other financial institutions where to send money. Your account number (10 digits) identifies your specific account within Chase.
When you set up direct deposit at work or arrange a wire transfer, you typically need both numbers. The routing number directs the money to Chase; the account number directs it to your specific account. If you provide only the routing number without the account number, the transfer will fail or be rejected.
Why account numbers matter for transfers and payments
Your account number is required for any transaction that moves money into or out of your account without a debit card or check. This includes setting up direct deposit from your employer, arranging automatic bill payments, or receiving wire transfers from another bank.
When you pay a bill online through Chase's bill pay service, the system uses your account number to debit the payment from your account. Similarly, if someone sends you a wire transfer, they need your account number (along with your name and routing number) to may support the money lands in the right place.
Security: what not to do with your account number
Your account number is not as sensitive as your PIN or password, but it should still be treated carefully. Never share it with someone who contacts you unsolicited by phone, email, or text. Legitimate Chase representatives will never ask you to confirm your full account number unless you initiated the call.
If you share your account number with a business (like your employer for direct deposit or a utility company for automatic payments), that business can initiate transfers from your account. If you no longer want them to have access, you can revoke authorization through your bank or contact the business directly to cancel the arrangement.
What to do if you forget your account number
Forgetting your account number is not a problem and happens often. The fastest way to retrieve it is to log into your Chase online account or mobile app—it's displayed prominently on your dashboard. If you prefer not to use digital banking, call Chase customer service at 1-800-935-9935 with your Social Security number and date of birth ready for verification.
You can also visit a Chase branch in person with a valid ID, and a banker can provide your account number when ready. There is no fee for this service, and it takes less than a minute.
Frequently Asked Questions
Can I change my Chase checking account number?
No, your account number is permanent and cannot be changed. If you close your account and open a new one, you will receive a new account number. If you need a new account for a specific reason, contact Chase to discuss your options.
Is my account number the same across all my Chase accounts?
No. Each account you hold at Chase—whether it's a checking account, savings account, or money market account—has its own unique 10-digit account number. You cannot use one account's number for transactions on another account.
What if I give my account number to the wrong person?
Contact Chase when ready at 1-800-935-9935. While your account number alone cannot be used to withdraw cash or make purchases, it can be used to set up unauthorized transfers or bill payments. Chase can monitor your account and help you reverse any unauthorized transactions.
Do I need my account number to use my debit card?
No. Your debit card works independently of your account number. You only need your account number for transfers, direct deposits, wire transfers, and bill payments—not for everyday card purchases or ATM withdrawals.
