Chase bank account numbers have 10 digits
A Chase bank 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. The account number itself is just those 10 digits — it does not include your routing number, which is a separate 9-digit code that identifies Chase as your bank.
When you're setting up direct deposit, paying bills online, or giving someone your banking details, you need both numbers. The routing number tells the sending bank where to send the money; the account number tells Chase which account within the bank should receive it. Confusing the two or transposing digits is one of the most common reasons transfers get delayed or sent to the wrong place.
Key Takeaways
- Chase account numbers are always 10 digits, and you can find yours on a check, in the Chase app, or by calling customer service.
- Your routing number (9 digits) and account number (10 digits) are different codes that work together for transfers and direct deposit.
- The account number appears on the bottom left of checks, after the routing number and before the check number.
- Double-checking both numbers before submitting a transfer prevents money from going to the wrong account or being delayed.
Where to find your 10-digit account number
The easiest place to locate your account number is on a paper check. Look at the bottom of the check from left to right: you'll see the routing number first (9 digits), then your account number (10 digits), then the 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 or account summary section.
You can also call Chase customer service at the number on the back of your debit card. A representative can read your account number to you over the phone. Some people take a photo of a check or write down the number for future reference, since you'll need it repeatedly for things like setting up payroll direct deposit or authorizing automatic bill payments.
How the account number works with your routing number
Your routing number and account number are a paired system. The routing number is 9 digits and identifies Chase Bank as the institution. The account number is 10 digits and identifies your specific account within Chase. When you give someone these two numbers together, they have everything needed to send money to you electronically.
If you provide only the account number without the routing number, the sender's bank won't know which bank to send the money to. If you provide only the routing number, Chase won't know which account to credit. Both are required for ACH transfers (the system used for direct deposit and bill pay), wire transfers, and other electronic payments. This is why banks always ask for both.
What happens if you give the wrong account number
If you transpose digits or provide an incorrect 10-digit account number, the transfer may be rejected outright if the number doesn't match any valid Chase account. In other cases, the money might be sent to a different Chase customer's account by mistake. This is rare but does happen, and recovering the funds can take weeks because the receiving bank has to contact the other account holder and request a reversal.
To avoid this, always double-check the account number before confirming a transfer. If you're setting up direct deposit with an employer, verify the number matches what appears in your Chase app or on a recent check. If you're sending money to someone else, ask them to confirm the number matches their bank statement or app, not just what they remember.
Account numbers for different types of Chase accounts
Whether you have a Chase checking account, savings account, money market account, or credit card, each one has its own separate 10-digit account number. If you have multiple accounts at Chase, do not assume the numbers are similar or sequential — they are independent numbers. This matters because if you're setting up a transfer between your own accounts, you need the correct account number for each one.
Credit card accounts also have account numbers, but they function differently than bank account numbers. A credit card account number is typically 16 digits and is used for purchases and payments, not for receiving electronic transfers. If someone asks for your "account number" for a bank transfer, they mean your checking or savings account number (10 digits), not your credit card number.
Why Chase uses 10 digits instead of a different length
The 10-digit standard for Chase checking and savings accounts is an industry convention, not a Chase-specific rule. Most major U.S. banks use 10-digit account numbers for consumer accounts, though some smaller banks or credit unions may use different lengths. The 10-digit format has been standard long enough that it's built into the ACH system and most payroll software, so changing it would create widespread problems.
The combination of a 9-digit routing number and a 10-digit account number gives banks enough unique combinations to serve millions of customers without running out of numbers. If you're moving money between different banks, each bank's routing number tells the system where to go, and the account number tells that bank which account to use.
Frequently Asked Questions
Can I change my Chase account number?
No, your account number is permanent and cannot be changed. If you close an account and open a new one, you'll receive a new account number. If you're concerned about fraud or security, contact Chase directly — they can help you secure the account without changing the number itself.
Is my Chase account number the same as my card number?
No. Your debit card has a 16-digit card number printed on it, which is different from your 10-digit bank account number. Your account number is used for transfers and direct deposit; your card number is used for purchases and ATM withdrawals. Never confuse the two when providing banking details.
What if I only have the last four digits of my account number?
The last four digits alone are not enough to complete a transfer — you need all 10 digits. If you've forgotten your full account number, log into your Chase app, check a recent check, or call Chase customer service. They can provide the complete number in seconds.
Do I need to memorize my 10-digit account number?
You don't need to memorize it, but it's helpful to write it down or save it somewhere secure for reference. Most people keep it in a password manager, a note in their phone, or on a copy of a check. You'll need it often enough that having quick access saves time.
