Chase checking account numbers have 10 digits

A Chase checking 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 is different from your routing number, which is 9 digits and tells banks where to send money. When you're setting up direct deposit, paying bills, or receiving a wire transfer, you'll need 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 routing number (9 digits) and account number (10 digits) are two separate pieces of information you may need together.
  • You can find your account number in your Chase mobile app, online banking, or by calling 1-800-935-9935.
  • Never share your full account number with anyone unless you initiated the transaction or verified the request yourself.

Where to find your 10-digit account number

The easiest place to locate your account number is on a check. Look at the bottom of the check — you'll see three groups of numbers. The first group (9 digits) is your routing number. The second group (10 digits) is your account number. The third group is the check number itself.

If you don't have checks handy, log into your Chase online banking account or open the Chase mobile app. Your account number appears on the account summary page, usually near the top. You can also call Chase at 1-800-935-9935 and speak with a representative who can read it to you over the phone.

Why the length matters when you're setting up payments

Knowing that your account number is exactly 10 digits helps you catch mistakes before they cause problems. If someone asks you for an account number and you count 9 or 11 digits, something is wrong — you may have included your routing number by accident, or the person asking may have given you incorrect instructions.

When you're setting up direct deposit with an employer, transferring money between banks, or authorizing a payment, double-check that you're entering only the 10-digit account number in the account number field. Entering extra digits can cause the transaction to fail or route to the wrong place.

The difference between your account number and routing number

Your routing number (9 digits) identifies which Chase branch or processing center handles your account. Your account number (10 digits) identifies your specific account within Chase's system. Together, they form the complete address for your money.

When you receive money via direct deposit or wire transfer, the sender needs both numbers. When you're paying a bill from your Chase account, you typically only need to provide your account number — the biller already knows Chase's routing number. Always verify what information is actually needed before you share anything.

What to do if you see a different number of digits

If you're looking at a number that doesn't match the 10-digit pattern, you may be looking at a different identifier. Some Chase accounts have additional reference numbers for specific purposes — like a credit card account number (which is 16 digits) or a savings account number (also 10 digits, but separate from your checking account).

If you're unsure whether you have the right number, call Chase directly at 1-800-935-9935. Don't rely on a number someone else gave you or found online. A Chase representative can confirm your account number and tell you exactly which number you need for whatever you're trying to do.

Security: why you should protect your account number

Your 10-digit account number, combined with your routing number, is enough information for someone to set up unauthorized transfers from your account. This is why you should never share your account number with anyone unless you initiated contact with them or you've verified their identity through an official Chase channel.

If you suspect someone has your account number and you didn't authorize it, contact Chase when ready at 1-800-935-9935. They can monitor your account for suspicious activity and issue you a new account number if necessary. The sooner you report it, the faster they can act.

Frequently Asked Questions

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

No. Your debit card number is 16 digits and is printed on the front of your card. Your checking account number is 10 digits and appears on your checks and in your online banking. They're linked to the same account, but they're different numbers.

Do all Chase accounts have 10-digit account numbers?

Chase checking and savings accounts both use 10-digit account numbers. Credit card accounts use a different numbering system (16 digits). If you have multiple account types with Chase, each one has its own 10-digit account number.

What if I only have part of my account number?

If you have your debit card or a recent statement, you can find your full 10-digit account number there. You can also log into your Chase online banking or call 1-800-935-9935 to retrieve it. Never guess or use a partial number for a transaction.

Can I change my Chase account number?

Chase can issue you a new account number if there's fraud or security concerns, but you cannot request a number change for other reasons. If you need a new account number, call Chase at 1-800-935-9935 and explain the situation. They'll tell you whether a change is possible.
