Your checking account number is on the bottom left of your checks, in your Chase mobile app, or by calling Chase customer service

Your checking account number is a unique identifier for your specific account at Chase. You need it to set up direct deposit, arrange wire transfers, pay bills by phone, or give someone else permission to deposit money into your account. Chase prints it on every check you order, displays it in the app, and can tell you over the phone in seconds.

The fastest way to find it depends on what you have access to right now. If you have a check, look at the bottom. If you have your phone, open the Chase app. If you need it immediately and have neither, a quick call to Chase gets you the answer without waiting for mail or logging in online.

Key Takeaways

  • Your account number appears on the bottom left of every check you write, printed between two colons.
  • The Chase mobile app shows your full account number in the account details section without requiring a separate login.
  • Chase.com displays your account number when you log in and navigate to your account information or account settings.
  • Calling Chase customer service at the number on the back of your debit card will connect you to someone who can read your account number aloud in under a minute.
  • Your account number is not the same as your routing number, which is also printed on checks but identifies Chase itself, not your individual account.

Finding your account number on a check

Look at the bottom of any check you have written or received. You will see a series of numbers printed in magnetic ink. The first set of numbers on the left is your routing number (identifies Chase). The middle set is your account number. The last set on the right is the check number.

The account number is typically 10 to 12 digits long, though the exact length varies. It will be positioned between two colons or in a clearly separated section. If you have not ordered checks yet or yours are blank, this method will not work — move to the app or website instead.

Finding your account number in the Chase mobile app

Open the Chase mobile app and sign in with your username and password. Tap on the checking account you want to look up. At the top or in a menu labeled "Account Details" or "Account Information," your full account number will be displayed. Some versions of the app show it directly on the account summary screen; others require you to tap a details button.

The app does not require you to verify your identity a second time once you are logged in, so this is usually the fastest digital method. You can screenshot the number or write it down. If you cannot find the account details section, swipe left or right on the account tile to reveal additional options.

Finding your account number on Chase.com

Log into your Chase account at Chase.com. Click on the checking account you need. Look for a link or button labeled "Account Details," "Account Information," or "Account Settings." Your account number will be displayed there, often alongside your routing number and other account information.

Some Chase accounts also show the account number in a section called "Account Summary" or when you hover over the account name. If you are setting up direct deposit or a transfer, Chase will often display your account number automatically on the form you are filling out, so you may not need to hunt for it separately.

Calling Chase to get your account number

Call the customer service number on the back of your Chase debit card or check. You can also call Chase directly at 1-800-935-9935. When you reach a representative, provide your name and the last four digits of your Social Security number or the card number associated with your account. They will verify your identity and read your account number to you.

This method works at any time, including nights and weekends when Chase customer service is staffed. The call usually takes fewer than five minutes. Have a pen ready to write down the number, or ask the representative to repeat it slowly so you can confirm each digit.

The difference between your account number and routing number

Your routing number identifies Chase Bank as the institution. Your account number identifies your specific account within Chase. Both appear on your checks, but they serve different purposes. When you set up direct deposit, your employer needs both numbers. When you receive a wire transfer, the sender needs both numbers. When you pay a bill by phone, you usually only need your account number.

Chase's routing number is 021000021 for most accounts, though some older accounts or specialty products may have a different routing number. Your account number is unique to you and changes only if you close the account and open a new one. If you are unsure which number you need for a specific transaction, ask the person or organization requesting it — they will tell you which one applies.

What to do if you cannot access your account

If you have forgotten your Chase password, you can reset it on the login page without needing your account number. If your account is locked or frozen, or if you cannot log into the app or website for any reason, call Chase customer service. They can verify your identity by other means and provide your account number over the phone.

If you have lost access to the phone number or email associated with your account, bring a government-issued ID to a Chase branch in person. A banker can verify your identity and help you regain access to your account information. This is also the fastest way to get your account number if you do not have a check, phone, or internet access available.

Frequently Asked Questions

Is my account number the same as my debit card number?

No. Your debit card number is printed on the front of your card and is different from your account number. Your account number is what you use for direct deposits, wire transfers, and bill payments. Your card number is what you use to make purchases or withdraw cash. Both are linked to the same account, but they are separate numbers.

Can I change my account number?

You cannot change your existing account number. If you need a different account number, you would have to close your current account and open a new one. This is rarely necessary. If you are concerned about fraud or security, contact Chase directly — they can help you secure your account without closing it.

Do I need to memorize my account number?

No. You can look it up whenever you need it using the methods described above. Most people write it down or take a screenshot when they need to provide it to an employer or lender. Keeping it in a secure place at home is safer than memorizing it.

What if I see a different account number in the app than on my checks?

This is unusual but can happen if you have multiple accounts or if there is a display error. Call Chase to confirm which number is correct. Do not use a number you are unsure about for direct deposit or wire transfers, as sending money to the wrong account number can delay or lose the transaction.
