Chase checking accounts have two separate number systems

A Chase checking account uses two different numbers, and they serve different purposes. The first is your account number, which identifies your specific account at Chase. The second is your routing number, which tells other banks and payment systems how to find Chase itself. You need both pieces of information to receive money from outside sources — direct deposits, wire transfers, or payments from other people's accounts.

Your account number is typically 10 digits long. Your routing number is always 9 digits. Together, they form the complete address for your account in the banking system. Neither one is secret in the way a password is — you give out both regularly when you set up direct deposit or ask someone to send you money.

The routing number is the same for all Chase customers in your region. The account number is unique to you. This is why you can safely write your account and routing numbers on a check or give them to your employer — they identify where your money should go, but they do not let someone withdraw from your account or access your balance.

Key Takeaways

  • A Chase checking account has a 10-digit account number and a 9-digit routing number, and you need both to receive transfers from outside sources.
  • The routing number is the same for all Chase customers in your region, while the account number is unique to your account only.
  • You can find both numbers on the bottom left of your checks, in the Chase mobile app, or by calling Chase customer service.
  • The account number and routing number are not secret — you share them whenever you set up direct deposit or ask someone to send you money.

Where to find your account and routing numbers

The easiest place to locate both numbers is on a check from your Chase checking account. Look at the bottom left corner. The first set of numbers is your routing number (9 digits). when ready after that, separated by a colon or small space, is your account number (10 digits). The third set of numbers on the bottom is the check number itself.

If you do not have checks, open the Chase mobile app or log into Chase.com. Go to your account details or account information section — the exact location varies slightly depending on whether you use the app or website, but it is always labeled clearly. Your account number and routing number will both be displayed there. You can also call Chase customer service at the number on the back of your debit card, and a representative will read both numbers to you over the phone.

Why you need both numbers for different transactions

When you set up direct deposit with your employer, you provide both numbers so payroll knows exactly where to send your paycheck. The routing number tells the employer's bank which bank to contact (Chase). The account number tells Chase which account within the bank should receive the deposit.

The same applies when someone sends you a wire transfer, an ACH transfer (which takes one to three business days), or a payment through an app like Zelle. Each system uses the routing number to locate Chase and the account number to locate your specific account. Without either number, the transfer cannot reach you.

When you write a check, you only write your account number on the check itself — the routing number is pre-printed. The person depositing the check uses the routing number that is already printed there, so you do not need to write it again.

The difference between account number and routing number

Your account number is personal to you. It changes only if you close the account and open a new one. It appears on your statements, your debit card, and your checks. It is the permanent identifier for that specific account.

Your routing number depends on which Chase branch region you use, not on your individual account. All Chase customers in the same region share the same routing number. If you move to a different state or region, your routing number may change, but your account number stays the same. Chase has multiple routing numbers because the banking system routes transfers through regional processing centers.

You can have multiple Chase checking accounts, and each one will have its own unique account number. But if both accounts are in the same region, they will share the same routing number.

What these numbers do and do not protect

Your account and routing numbers are designed to direct money into your account, not to let someone take money out. Sharing these numbers with your employer, your landlord, or anyone else who needs to send you money is safe. They cannot use these numbers to withdraw funds, change your password, or access your balance.

Your account number does appear on your debit card, and it is printed on every check you write, so it has never been treated as confidential information. The routing number is public — it is published by the Federal Reserve and is the same for thousands of Chase customers.

What you should keep private are your PIN, your online banking password, and your full debit card number with expiration date and CVV. Those are the pieces of information that let someone actually move money out of your account or make purchases.

If you need a different account number

You cannot change your account number while keeping the same account open. If you want a new account number, you must close your current checking account and open a new one. Chase will assign you a new account number automatically when you open the new account.

Some people close and reopen accounts for security reasons — for example, if they believe their account number has been compromised or if they want to stop automatic payments that are difficult to cancel. Keep in mind that closing an account can affect your banking history and credit report if the account had overdrafts or other issues. Before you close an account, make sure all automatic deposits and payments are redirected to your new account.

Frequently Asked Questions

Can someone withdraw money from my account if they have my account and routing numbers?

No. These numbers are designed to direct money into your account, not out of it. Someone would need your PIN, online password, or debit card details to withdraw or spend your money. You can safely share your account and routing numbers with employers, landlords, and anyone else who needs to send you money.

Do I need to memorize my account and routing numbers?

You do not need to memorize them, but it is useful to know where to find them quickly. Keep a photo of a check or a note with both numbers in a safe place. You will need them when setting up direct deposit, requesting wire transfers, or filling out banking forms.

What if I have multiple Chase checking accounts?

Each account has its own unique 10-digit account number. If all your accounts are in the same region, they share the same 9-digit routing number. When you set up direct deposit or request a transfer, make sure you provide the correct account number for the specific account you want the money to go into.

Will my routing number change if I move to a different state?

It may. Chase routing numbers are assigned by region, so moving to a different state could mean a different routing number. Check your new checks or log into your account after you move to confirm your current routing number. Your account number stays the same regardless of where you live.

Where is the account number on my Chase debit card?

Your account number appears on your debit card, but it is not the same as the card number. The card number is the 16-digit number on the front. Your account number is shorter (10 digits) and may be printed on the card or visible only in your online account details, depending on your card design.
