How Many Digits Are in a Chase Bank Account Number

Chase bank account numbers have 10 digits

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

This 10-digit format is standard across Chase's consumer and business accounts. Whether you have a checking account, savings account, or money market account with Chase, the account number portion will be 10 digits. This is different from your routing number, which identifies Chase as your bank, and different from the full string of numbers on a check, which includes both the routing number and account number together.

Key Takeaways

• Chase account numbers are always 10 digits, found on checks, statements, and in the Chase app.
• The account number is separate from your routing number, which identifies Chase as your bank.
• A check displays both the routing number and account number, but only the 10-digit portion is your account number.
• You need both your routing number and 10-digit account number to set up direct deposit or wire transfers.

Where to find your 10-digit account number

The easiest place to find your account number is the Chase mobile app. Log in, select the account you want, and look for the account number displayed on the account details screen. You can usually copy it directly from the app.

On a paper check, look at the bottom. You'll see three groups of numbers separated by colons or special symbols. The middle group is your 10-digit account number. The first group (usually 9 digits) is your routing number. The last group is the check number.

Your monthly Chase statement also displays your account number, typically near the top or in the account information section. If you don't have a check or statement handy, you can call Chase customer service at the number on the back of your debit card, and they'll provide your account number over the phone after verifying your identity.

Account number versus routing number

People often confuse these two numbers because they appear together on checks, but they serve different purposes. Your routing number tells the banking system which bank holds your account — Chase's routing number is 021000021 for most consumer accounts, though it can vary by location and account type. Your account number identifies your specific account within Chase's system.

When you set up direct deposit at work, your employer needs both numbers. When you receive a wire transfer, the sender needs both. If you only provide one, the transaction won't go through correctly. Some forms ask for your "account and routing number" as a single field — in that case, you typically enter the routing number first, then the account number, though the format can vary by institution.

Why the 10-digit format matters

The 10-digit standard is a banking industry convention that makes account numbers consistent and easier to process electronically. Banks use this format to prevent errors when routing money between institutions. If you accidentally provide 9 digits or 11 digits, the transaction will likely be rejected or delayed.

When you're setting up automatic payments, transferring money between banks, or receiving deposits, always double-check that you've entered exactly 10 digits. A single missing or extra digit can send your money to the wrong place or cause the transaction to fail entirely.

What happens if you share your account number

Your 10-digit account number alone cannot be used to withdraw money from your account. Someone would need both your account number and your routing number, plus authorization to initiate a transaction. However, it's still smart to treat your account number as sensitive information and only share it with people and organizations you trust.

If you're concerned that your account number has been compromised, contact Chase when ready. They can monitor your account for unauthorized activity and issue you a new account number if necessary, though this process takes time and affects any automatic payments or direct deposits you have set up.

Frequently Asked Questions

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

No. Your debit or credit card number is different from your bank account number. Your card number is 16 digits (for most Chase cards) and is printed on the front of the card. Your account number is 10 digits and is not printed on the card itself — you have to look it up separately.

Do all Chase accounts have 10-digit account numbers?

Yes. All Chase consumer checking, savings, and money market accounts use 10-digit account numbers. Business accounts also follow this format. The only exception would be older accounts that may have been converted or merged, but Chase would have assigned a 10-digit number in that case.

Can I change my Chase account number?

Chase does not allow you to choose a different account number. If you need a new account number for security reasons, you would have to close your current account and open a new one. This is a significant step because any automatic payments or direct deposits tied to the old number will need to be updated.

What if I only have 9 digits or 11 digits?

Double-check that you're reading the number correctly. Look at your check again or log into the Chase app to confirm. If you're still seeing a different number of digits, contact Chase customer service — there may be a display error or you may be looking at a different number (like your routing number or card number by mistake).

Do I need my account number to log into Chase online?

No. You log into Chase with your username and password, not your account number. However, you'll need your account number once you're logged in if you want to perform certain transactions like setting up transfers or providing it to someone else.
