Chase account numbers have 10 digits
A Chase bank account number is 10 digits long. When you look at a check or your online banking portal, you will see this 10-digit number printed or displayed as your account identifier.
This 10-digit account number is specific to you and that particular account. If you have multiple accounts at Chase — a checking account and a savings account, for example — each one has its own separate 10-digit number. The number never changes as long as the account remains open.
Key Takeaways
- Chase account numbers are always 10 digits, whether you have a checking, savings, or money market account.
- Your routing number (9 digits) and account number (10 digits) work together to identify both your bank and your specific account.
- You can find your account number on the bottom left of your checks, in the Chase mobile app, or by logging into your online account.
- The account number alone is not enough to transfer money — you also need the routing number, which tells the system which Chase location processes your account.
Where to find your 10-digit account number
The easiest place to see your account number is on a check from your checking account. Look at the bottom left of the check. You will see three sets of numbers: the routing number (9 digits), then your account number (10 digits), then the check number.
If you do not have checks handy, log into your Chase account online or open the Chase mobile app. Your account number appears in the account details section, usually labeled "Account Number" or "Account Information." You can also call Chase customer service at the number on the back of your debit card, and they will read it to you over the phone.
How the account number works with your routing number
Your account number and routing number are two separate pieces of information that work together. The routing number (9 digits) tells the banking system which Chase branch or processing center handles your account. The account number (10 digits) identifies which specific account at that location is yours.
When you set up a direct deposit, make a wire transfer, or give someone your banking information to send you money, you need both numbers. Without the routing number, the money does not know which bank to go to. Without the account number, the bank does not know which of its thousands of accounts should receive the money. Both pieces are required for the transaction to reach the right place.
Why account numbers are always 10 digits at Chase
Banks use a fixed number of digits for account numbers so their computer systems can process transactions consistently. Chase standardized on 10 digits for all its consumer accounts — checking, savings, money market, and others. This means you can expect the same format no matter what type of account you open with them.
The 10-digit format gives Chase enough combinations to assign a unique number to millions of customers without running out of numbers. It also makes it easier for their systems to validate that an account number is real before processing a transfer or deposit. The consistency across all account types simplifies how Chase's internal systems handle routing and verification.
What happens if you write down the number wrong
If you give someone an incorrect account number, the money may go to the wrong account or be rejected entirely. Some banks have systems that catch mismatched numbers before the transfer goes through. Others process the transfer and then have to reverse it later, which can take several business days.
Always double-check your account number when you share it, especially for large transfers or recurring payments like direct deposit. If you are unsure, verify it directly from your check or your online account rather than relying on memory or a number you wrote down weeks ago. A single digit wrong can send money to the wrong place.
Account numbers for different Chase account types
Whether you have a Chase Total Checking account, a Chase Savings account, a Chase Money Market account, or any other Chase product, the account number will always be 10 digits. Each account type uses the same numbering system, so you will never encounter a Chase account number that is longer or shorter than 10 digits.
If you have both a checking and a savings account at Chase, they will have different 10-digit account numbers. The routing number may be the same for both accounts (depending on which Chase location processes them), but the account numbers will be unique to each account. This separation ensures that deposits and transfers go to the correct account type.
Frequently Asked Questions
Can I change my Chase account number?
No, your account number is permanent and tied to your account. If you close the account and open a new one, you will receive a new account number. But you cannot change the number on an existing account.
Is my account number the same as my debit card number?
No, they are different. Your debit card has its own 16-digit number printed on the front. Your account number is 10 digits and is used for transfers and direct deposits, not for card purchases.
What is the routing number for Chase?
Chase has multiple routing numbers depending on which state your account is processed in. You can find the correct routing number on the bottom left of your checks, or by calling Chase customer service. The most common routing number for Chase is 021000021, but yours may be different based on your location.
Do I need to memorize my account number?
You do not need to memorize it, but it is helpful to have it written down somewhere safe. Keep a record of both your account number and routing number in case you need them for direct deposit, wire transfers, or other banking tasks.
Where do I find my account number if I do not have checks?
Log into your Chase online account or mobile app and look for the account details section. You can also call the customer service number on the back of your Chase debit card, and a representative will provide your account number over the phone.
