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 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 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 is a separate 9-digit code that identifies which Chase branch or processing center handles your account.

Understanding the difference between these two numbers matters because you'll need both when setting up direct deposits, wire transfers, or automatic bill payments. Many people confuse the two or think they're the same thing, which can cause delays or failed transactions. Knowing that your account number is specifically the 10-digit portion helps you provide the correct information the first time.

Key Takeaways

  • Chase account numbers are always exactly 10 digits, regardless of account type.
  • Your account number appears on the bottom left of checks, after the routing number.
  • The routing number (9 digits) and account number (10 digits) are two separate pieces of information you may need for transfers or payments.
  • You can find your account number in the Chase mobile app, online banking, or by calling 1-800-935-9935.

Where to find your Chase account number

The easiest place to locate your account number is on a check from your Chase checking account. Look at the bottom of the check: you'll see three groups of numbers separated by colons or special symbols. The first group is the routing number (9 digits), the second group is your account number (10 digits), and the third group is the check number.

If you don't have checks handy, log into your Chase online banking account or open the Chase mobile app. Your account number will be displayed on your account dashboard or in your account details. You can also call Chase at 1-800-935-9935 and speak with a representative who can confirm your account number over the phone after verifying your identity.

For business accounts, the same locations apply — checks, online banking, the mobile app, or a phone call to Chase. The process is identical whether you're managing a personal or business account.

Why you need both your routing number and account number

Your routing number and account number work together to identify your specific account at Chase. When you set up a direct deposit, make an electronic transfer, or arrange a wire transfer, you'll typically need to provide both numbers. The routing number tells the banking system which Chase location processes your account, while the account number identifies which specific account at that location receives the funds.

If you only provide the account number without the routing number, the transfer may fail or be delayed because the system won't know which bank to send the money to. Similarly, providing just the routing number without the account number won't work — the funds need both pieces of information to reach the right place. Think of it like an address: the routing number is the city, and the account number is the specific house.

This is why employers ask for both when you're setting up direct deposit, and why bill payment services require both numbers before they can process a payment from your account.

What happens if you share your account number

Your account number alone is generally safe to share with people who need to send you money, such as your employer for direct deposit or a company processing a payment. However, you should never share your account number along with other sensitive information like your PIN, password, or Social Security number.

If you're concerned that your account number has been compromised or used without your permission, contact Chase immediately at 1-800-935-9935. Chase can review your account for unauthorized activity and take steps to protect it. You can also report fraud through your online banking portal or mobile app, which will flag your account for investigation.

Account numbers for different Chase account types

All Chase consumer accounts — checking, savings, money market, and certificates of deposit — use the same 10-digit account number format. Business accounts at Chase also follow this same structure. The account number doesn't change based on what type of account you have; it's simply a unique identifier for that specific account.

If you have multiple accounts with Chase, each one will have its own separate 10-digit account number. Your routing number will be the same across all your Chase accounts (assuming they're all at the same branch or processing center), but each account gets its own unique number. This allows you to direct deposits or transfers to a specific account when you have more than one.

Frequently Asked Questions

Can I change my Chase account number?

No, you cannot change your account number. It's a permanent identifier assigned to your account when you open it. If you close the account and open a new one, you'll receive a new account number, but you cannot request a different number for an existing account.

Is my account number the same as my card number?

No. Your Chase debit card or credit card has its own separate card number printed on the front. Your bank account number is different and is used for transfers, direct deposits, and bill payments. The card number is used for purchases and card-based transactions.

What if I can't remember my account number?

You can find it by logging into your Chase online account, checking a blank check, or calling Chase customer service at 1-800-935-9935. A representative can provide your account number over the phone after verifying your identity.

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

No. You log into Chase online banking using your username and password or your card number and PIN. Your account number is not used for login purposes — it's only needed when you're setting up transfers, payments, or sharing banking information with others.
