Chase account numbers have 10 digits

A Chase checking or savings account number is always 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 — nothing more, nothing less.

This 10-digit format is specific to Chase. Other banks use different lengths, so if you're moving money between Chase and another institution, don't assume the account number will be the same length. The routing number (which tells the banking system which Chase branch or processing center to use) is separate and is always 9 digits.

Key Takeaways

  • Chase account numbers are exactly 10 digits, whether you have a checking account, savings account, or money market account.
  • Your account number appears on the bottom left of your checks, in the Chase mobile app under account details, and on your monthly statement.
  • The routing number (9 digits) and account number (10 digits) are two different things and both are needed for wire transfers or external transfers.
  • If you see a number longer than 10 digits on your Chase paperwork, the extra digits are usually a check number or reference code, not part of your account number.

Where to find your 10-digit account number

The easiest place to look is the bottom of any check you have. The account number sits between the routing number (on the left) and the check number (on the right). If you don't have checks, log into your Chase online account or mobile app, go to account details or account information, and your 10-digit account number will be listed there.

You can also call Chase at the number on the back of your debit card. A representative can read your account number to you over the phone. If you're setting up a direct deposit or external transfer, Chase will often display your account number in the transfer setup screen so you can copy it directly.

Why the length matters for transfers and payments

When you're setting up a wire transfer, ACH transfer, or linking your Chase account to another bank, the receiving institution needs your account number to be exactly 10 digits. If you enter fewer or more digits, the transfer will be rejected or sent to the wrong account.

Some people accidentally include leading zeros or extra characters when copying their account number. Make sure you're entering only the 10 digits with no spaces, dashes, or letters. If a form asks for more than 10 digits and labels it as your account number, you're probably looking at a different field — check the label to be sure.

The difference between account number and routing number

Your routing number (9 digits) identifies which Chase location or processing center handles your account. Your account number (10 digits) identifies your specific account within Chase. Both are required for most transfers, but they serve different purposes.

On a check, the routing number appears first (leftmost), then your account number, then the check number. When you set up direct deposit or link accounts, you'll usually be asked for both. If you only provide one, the transaction won't go through.

What to do if you can't find your account number

If you don't have access to checks or your online account, call Chase at 1-800-935-9935 (the number on most Chase debit cards). Have your Social Security number and a form of ID ready. A representative will verify your identity and provide your 10-digit account number.

You can also visit a Chase branch in person with your ID. Any teller can look up your account number and write it down for you. This is useful if you need it when ready and don't want to wait for a phone call.

Common confusion about account number length

Some people see a longer string of numbers on their Chase statement or in their online account and think that's their account number. Often, what they're seeing is a reference number, transaction ID, or a combined display that includes the check number. The actual account number is always 10 digits.

If you're copying your account number from a statement, look for the label that says "Account Number" or "Account #" — that's the 10-digit number you need. If you're unsure, it's safer to log into your online account or call Chase directly rather than guess.

Frequently Asked Questions

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

No. Your debit card number (16 digits) is different from your account number (10 digits). They're linked to the same account, but they're separate numbers. If someone asks for your account number, don't give them your card number instead.

Do all Chase accounts have 10-digit account numbers?

Yes. Whether you have a checking account, savings account, money market account, or any other deposit account at Chase, the account number is 10 digits. Business accounts follow the same format.

What if I entered the wrong account number for a transfer?

If the number you entered doesn't match an existing account, the transfer will be rejected and the money returned to you. If the number matches someone else's account, the transfer may go through to the wrong person. Contact Chase when ready if this happens — they can sometimes reverse the transfer, but speed matters.

Can I change my Chase account number?

No, you cannot change your account number. It's assigned when you open the account and stays the same for the life of that account. If you want a new account number, you would need to close the current account and open a new one, which is rarely worth the hassle.

Why does Chase use 10 digits instead of a different length?

The 10-digit format is Chase's internal standard and has been for decades. Different banks use different lengths — some use 8 digits, others use 12 or more. There's no universal standard across the banking system, so each bank sets its own.
