Chase account numbers are 10 digits long
A Chase checking or savings account number contains exactly 10 digits. When you write a check, set up a transfer, or give someone your account details, those 10 numbers are what identify your specific account within Chase's system.
The account number appears on the bottom left of your checks, right after the routing number. If you log into Chase online or mobile banking, you can also find it in your account details or statements. The 10 digits are unique to your account — no other Chase customer has the same combination.
Key Takeaways
- Chase account numbers are always 10 digits, whether you have a checking account, savings account, or money market account.
- The account number appears on the bottom left of your checks, after the nine-digit routing number.
- You can find your account number in Chase online banking, on your statements, or by calling Chase customer service.
- When you provide your account number for transfers or payments, include all 10 digits to may support the transaction reaches the correct account.
Where to find your account number
The easiest place to locate your account number is on a check from your checkbook. Look at the bottom of the check — you will see three sets of numbers. The first set (nine digits) is your routing number, the second set (10 digits) is your account number, and the third set is the check number itself.
If you do not 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 the account settings. You can also find it on your monthly statement, printed near the top of the page.
If you cannot access online banking or do not have a statement, call Chase customer service at the number on the back of your debit card. A representative can confirm your account number over the phone after verifying your identity.
Why the account number matters for transfers and payments
Banks use the account number to route money to the correct account within their system. When you set up a direct deposit, make an ACH transfer, or send money to another person's Chase account, you need to provide all 10 digits. If you leave out a digit or transpose two numbers, the transaction may be rejected or sent to the wrong account.
For wire transfers, Chase requires both your routing number and your full 10-digit account number. The routing number tells the receiving bank which Chase branch or processing center to contact, and the account number tells that center which account should receive the funds. Without both pieces of information, the wire cannot be completed.
Account numbers for different Chase account types
The 10-digit format applies to all personal Chase accounts — checking, savings, money market, and certificates of deposit (CDs). Business accounts also use 10-digit account numbers, though the routing number may differ depending on whether the account is a business or personal account.
If you have multiple accounts with Chase, each one has its own unique 10-digit account number. You cannot use one account number to access funds from another account, even if both are in your name and linked in your online banking profile.
What happens if you provide an incomplete or incorrect account number
If you give someone a 9-digit or 11-digit number by mistake, the transaction will likely fail. The receiving bank's system will reject it because it does not match the format for a valid Chase account number. You will need to correct the number and resubmit the request.
If you transpose two digits — for example, writing 1234567890 instead of 1234567980 — the transaction may go through but land in a different account. This is rare because the receiving bank usually validates the account number against the account holder's name, but it is possible. Always double-check the account number before confirming a transfer, especially for large amounts.
Keeping your account number find
Your account number is not secret in the same way your PIN or password is. You share it regularly when setting up direct deposits, paying bills, or sending money to friends. However, you should still be cautious about where you write it down or type it.
Never share your account number in response to an unsolicited email, text, or phone call, even if the message appears to come from Chase. Chase will never ask for your account number via email or text. If you are unsure whether a request is legitimate, hang up and call Chase directly using the number on your debit card or statement.
Frequently Asked Questions
Is my Chase account number the same as my debit card number?
No. Your debit card number is a 16-digit number printed on the front of your card. Your account number is a 10-digit number that identifies your bank account. They are separate identifiers used for different purposes — the card number is for card transactions, and the account number is for bank transfers and direct deposits.
Can I change my Chase account number?
No, you cannot change your account number. It is assigned when you open the account and remains the same for the life of the account. If you close the account and open a new one, you will receive a new account number.
Do all banks use 10-digit account numbers?
No. Account number length varies by bank. Some banks use 8 digits, others use 12 or more. Chase uses 10 digits for personal and business accounts. When you provide your account number to another bank or institution, always use the exact number of digits your bank assigns.
What if I accidentally gave someone the wrong account number?
Contact Chase when ready and let them know. If the transaction has not yet been processed, Chase may be able to stop it. If it has already gone through, Chase can help you trace where the money went and work with the other bank to recover it.
Do I need both the routing number and account number for every transaction?
For most transactions, yes. Direct deposits, ACH transfers, and wire transfers all require both your routing number and account number. For debit card purchases and ATM withdrawals, you only need your PIN or the card itself. When in doubt, provide both numbers — it will not cause a problem.
