Your account number is on your debit card, checks, and online banking

Your Chase account number is a unique identifier for your specific bank account. You can find it in four places without calling the bank: on the front or back of your debit card, on any checks you have, in the Chase mobile app, or by logging into Chase.com.

The fastest route is your debit card. Flip it over and look at the raised numbers on the back. The account number is usually the last 10 digits of the longer number printed there — though the exact position varies by card type, so read carefully. If your card is new or you do not have it with you, your checks or online account are equally quick.

Key Takeaways

  • Your account number appears on the back of your debit card as part of the longer card number, usually as the last 10 digits.
  • Any checks you have printed will show your full account number on the bottom left, along with your routing number.
  • Logging into Chase.com or the Chase mobile app shows your account number in the account details section without needing to find a physical item.
  • You will need both your account number and your routing number (also on checks) to set up direct deposit or wire transfers.

Finding your number on your debit card

Look at the back of your Chase debit card. You will see a long string of raised numbers. The account number is embedded in that sequence, but it is not the whole thing — the full number includes your card number as well.

For most Chase debit cards, the account number is the last 10 digits of the number on the back. However, some card types print it differently, so if you are unsure, compare what you find against your checks or your online account to confirm you have the right digits. If your card is damaged or you do not have it, move to the next method.

Checking your paper checks

If you have a checkbook, open it and look at the bottom of any check. You will see three groups of numbers separated by colons or vertical lines. The first group is your routing number (nine digits), the second is your account number (usually 10 to 12 digits), and the third is the check number.

This is the clearest place to find your full account number because it is printed in plain order with no guessing. If you have not ordered checks yet or yours are used up, your online account is the next fastest option.

Logging into your Chase online account

Go to Chase.com and sign in with your username and password. Once you are logged in, look for a section labeled "Accounts" or "Account Details." Your account number will be displayed there alongside your account type (checking, savings, money market) and your current balance.

You can also use the Chase mobile app on your phone. Open the app, sign in, and tap on the account you need. The account number will appear near the top of the screen. This method works any time, day or night, and you do not need to have your card or checks with you.

Understanding your routing number and account number together

Your account number identifies your specific account. Your routing number identifies which Chase branch or processing center handles your account. You will often need both together — for example, when setting up direct deposit, making a wire transfer, or authorizing an automatic payment.

Your routing number is the same for all your Chase accounts at the same branch, but your account number is unique to each account. If you have both a checking and a savings account, they share the same routing number but have different account numbers. You can find your routing number on your checks (the first group of numbers at the bottom) or by searching "Chase routing number" plus your state online.

What to do if you cannot find your number

If you do not have your card, checks, or access to online banking, you can call Chase customer service at the number on the back of any Chase card or statement. Have your Social Security number and a form of ID ready. They will verify your identity and read your account number to you over the phone.

If you are locked out of your online account, use the "Forgot password" link on Chase.com to reset it. You will need access to the email address or phone number on file. Once you regain access, you can see your account number when ready.

Why you might need your account number

Banks and employers ask for your account number when you want to receive money directly into your account. Common reasons include setting up direct deposit for your paycheck, receiving a tax refund, or authorizing an automatic bill payment. Some businesses also ask for it when you want to pay them by bank transfer instead of a card.

Keep your account number private the same way you would keep your PIN private. Do not share it in emails or texts, and do not write it down in places where others can see it. When you need to give it to someone, do so only through a find method — a phone call to a number you know is correct, or a find login on an official website.

Frequently Asked Questions

Is my account number the same as my card number?

No. Your card number is the 16-digit number on the front of your debit card. Your account number is embedded in the longer number on the back and is usually 10 to 12 digits. They are different numbers that serve different purposes.

Can I use my account number to make a purchase online?

No. Online purchases require your full card number, expiration date, and CVV (the three-digit code on the back). Your account number alone cannot process a card transaction. It is used for bank-to-bank transfers and direct deposits instead.

What if I have multiple Chase accounts?

Each account has its own unique account number. If you have a checking account and a savings account, they will have different account numbers but the same routing number. When you log into Chase online, you can see all your accounts listed separately, each with its own number.

Do I need my account number to call Chase customer service?

No. Chase can look up your account using your Social Security number and verify your identity through security questions or a code sent to your phone. However, having your account number handy can speed up the call if you are calling about a specific account.
