Your Chase ABA number is a nine-digit code that identifies which Chase branch or processing center handles your account
The ABA number (American Banker Association number) is not unique to you — it's tied to the bank location or processing center, not your individual account. Chase has multiple ABA numbers because it operates thousands of branches and regional processing centers across the country. When you set up a direct deposit, wire transfer, or automatic payment, you'll need to provide your ABA number along with your account number so the other bank knows exactly where to send or pull the money.
The ABA number appears on the bottom left of your checks, printed before your account number. If you don't have checks handy, you can find it through your Chase online banking portal, by calling Chase customer service, or by visiting your local branch. The number is always nine digits and follows a specific format that tells the Federal Reserve which bank and region processes your account.
Key Takeaways
- Your Chase ABA number is a nine-digit code printed on the bottom left of your checks, before your account number.
- The ABA number identifies the Chase branch or processing center that handles your account, not your account itself.
- You need your ABA number and account number together when setting up direct deposits, wire transfers, or automatic bill payments.
- Chase has different ABA numbers for different regions and account types, so verify you have the correct one for your specific account.
- You can find your ABA number on checks, through Chase online banking, by phone, or at your branch.
Where to find your ABA number on a check
Look at the bottom left corner of any check from your Chase account. You'll see nine digits printed in a specific order: the ABA number comes first, followed by your account number, then the check number on the right. The ABA number is always nine digits and uses a routing format that the banking system recognizes nationwide.
If your checks are old or you've switched account types, the ABA number may have changed. Chase sometimes assigns different routing numbers based on the type of account (checking versus savings) or the region where you opened it. If you're unsure whether the number on an old check is still current, verify it through your online account or by calling Chase.
How to find your ABA number without checks
Log into your Chase online banking account and look for account details or account information. Most banks display the routing number (another name for ABA number) in a section labeled "Account Details," "Routing Information," or "Wire Transfer Information." The exact location varies depending on whether you're using Chase's website or mobile app, but it's usually accessible from your account summary page.
You can also call Chase customer service at the number on the back of your debit card or find it on your monthly statement. When you call, have your account number ready and tell them you need your routing number for a direct deposit or transfer. A representative can confirm the correct nine-digit number in seconds and can also tell you if you have multiple accounts with different routing numbers.
If you visit a Chase branch in person, any teller can print your routing number for you or write it down while you wait. This is useful if you need it immediately and want to verify it face-to-face.
Why Chase has multiple ABA numbers
Chase operates as a large national bank with processing centers in different regions. The ABA number system was designed so that each bank location or processing center has its own routing identifier. This helps the Federal Reserve and other banks direct transactions to the correct place quickly. Even though you can walk into any Chase branch and access your account, the ABA number on your checks may correspond to the branch where you opened the account or the regional processing center that handles it.
If you move to a different state or switch to a different Chase branch, your ABA number might stay the same or might change depending on how your account is set up. This is why it's important to verify your current routing number rather than assuming an old one is still correct.
ABA number versus account number: what's the difference
Your ABA number identifies the bank and branch. Your account number identifies your specific account within that bank. Together, they form the complete routing information needed for any transfer or deposit. Think of the ABA number as the address of the bank and the account number as your mailbox within that building.
When you provide banking information to an employer for direct deposit, you'll give both numbers. The employer's payroll system uses the ABA number to find Chase, then uses your account number to deposit your pay into the right account. If you give only one number without the other, the transaction will fail or be delayed.
What to do if you have multiple Chase accounts
If you have more than one account at Chase — for example, a checking account and a savings account, or accounts at different branches — each account may have a different ABA number. This is especially true if you opened accounts in different states or regions. Before setting up a direct deposit or transfer, confirm which ABA number belongs to the specific account you want to use.
Log into each account separately through Chase online banking and check the routing number for that account. If the numbers differ, write them down and label them clearly so you don't mix them up. Using the wrong routing number for the right account will send the money to the wrong place.
Common mistakes when using your ABA number
The most common error is confusing the ABA number with the account number or transposing digits. Double-check that you're copying all nine digits correctly and in the right order. A single wrong digit will cause the transaction to fail or go to the wrong account.
Another mistake is using an outdated ABA number from an old check or statement. If you haven't used checks in a while or switched account types, verify your current routing number before setting up any automatic transfers. Chase customer service can confirm the correct number in one call.
Some people also assume that all their Chase accounts share the same ABA number. If you have multiple accounts, check each one separately rather than guessing.
Frequently Asked Questions
Is my ABA number the same as my routing number?
Yes, ABA number and routing number are the same thing. ABA stands for American Banker Association, and the nine-digit routing number is also called the ABA routing number. Banks use the terms interchangeably.
Do I need my ABA number to check my account balance or log in online?
No. You only need your ABA number when you're setting up transfers, direct deposits, or wire transfers with another bank or employer. For logging into Chase online banking or checking your balance, you use your username and password or your card number.
What if the ABA number on my check doesn't match the one shown in my online account?
Use the number from your online account or call Chase to verify. Checks can be outdated, and your routing number may have changed if you switched account types or if Chase updated its processing. The online account information is current.
Can I use the same ABA number for all my Chase accounts?
Not always. If your accounts are in different regions or are different types, they may have different routing numbers. Check each account separately in your online banking or call Chase to confirm the correct routing number for each one.
What happens if I give someone the wrong ABA number?
The transaction will fail or be rejected by the receiving bank. The money won't go through, and you'll be notified of the error. Verify the number before submitting it to avoid delays with direct deposits or bill payments.
