Chase checking account numbers have 10 digits

Your Chase checking account number is always 10 digits long. You can find it on the bottom left of your checks, in your Chase mobile app, or by calling Chase customer service. The account number itself is just those 10 digits — nothing more, nothing less.

This is different from your routing number, which is a separate 9-digit code that tells banks where to send money. When you give someone your account information for a direct deposit or wire transfer, you'll provide both numbers, but they serve different purposes.

Key Takeaways

  • Chase checking account numbers are always 10 digits, printed on the bottom left of your checks.
  • Your account number is different from your routing number, which has 9 digits and identifies your Chase branch.
  • You can see your full account number in the Chase mobile app under account details or by logging into Chase.com.
  • When setting up direct deposit or transfers, you will need both your 10-digit account number and your 9-digit routing number.

Where to find your 10-digit account number

The easiest place to look is the bottom of any check you have. The numbers are printed in a specific order: the routing number (9 digits) comes first on the left, then your account number (10 digits) in the middle, and finally the check number on the right. The account number is the middle set of digits.

If you don't have checks handy, log into your Chase account online or open the Chase mobile app. Go to your account details or account information section — it will show your full 10-digit account number there. You can also call Chase at the number on the back of your debit card and ask a representative to read it to you.

Why the account number is 10 digits

Chase uses a 10-digit format to create enough unique combinations for all of their checking accounts across the country. This length is an internal choice by Chase — other banks may use different lengths. The important thing is that Chase's format is always 10 digits, so if you see a number that's longer or shorter, you may have copied something else by mistake.

The 10 digits are just an identifier. They don't encode information about your branch, your account type, or your balance. They're straightforward a unique label that tells Chase's system which account is yours.

Account number vs. routing number: what's the difference

Your routing number is 9 digits and identifies which Chase branch or processing center handles your account. Your account number is 10 digits and identifies your specific account within that branch. When you set up direct deposit at work, for example, you'll give your employer both numbers so the money goes to the right place.

On a check, the routing number appears first (leftmost), and the account number appears in the middle. If you're ever unsure which is which, the routing number is always shorter — 9 digits instead of 10.

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

The fastest way is to log into Chase.com or the Chase mobile app. Your account number will be visible in the account details section without any extra steps. If you don't have online access set up yet, you can call Chase customer service at the number on the back of your debit card or on a recent statement, and they will read your account number to you over the phone.

You can also visit a Chase branch in person with your ID, and a teller can write down your account number for you. This takes longer than a phone call or app check, but it's an option if you prefer to handle it face-to-face.

Using your account number safely

Your 10-digit account number is not secret in the same way a password is — it appears on every check you write, and you have to share it with employers, landlords, and other organizations for direct deposits and payments. However, you should still be cautious about where you type it or who you give it to.

Never share your account number with someone who calls you unexpectedly claiming to be from Chase. Chase will never ask for your account number over the phone unless you called them first. If you're unsure, hang up and call the number on the back of your debit card to verify the request is real.

Frequently Asked Questions

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

No. Your debit card has a 16-digit number printed on the front. Your checking account number is 10 digits and is separate. You can have the same checking account but replace your debit card multiple times — each new card gets a new 16-digit number, but your account number stays the same.

Can I change my Chase account number?

Chase does not allow you to request a new account number for an existing account. Your account number is permanent for that account. If you close the account and open a new one, you will get a new account number, but you cannot change it while the account is active.

What if I see more than 10 digits on my check?

You may be looking at multiple numbers together. The check has the routing number (9 digits), account number (10 digits), and check number (usually 4 digits) all printed on the bottom. Make sure you're copying only the middle set of 10 digits for your account number.

Do all Chase accounts have 10-digit account numbers?

Chase checking accounts have 10-digit account numbers. Savings accounts and other account types may follow the same format, but if you're unsure about a different account type, check your statement or log into your account to confirm the exact number.
