Your account number is on your debit card, checks, and online banking
Your Chase account number is a 10-digit code that identifies your specific checking or savings account. You can find it in at least four places right now without calling anyone: on a check, on your debit card, in the Chase mobile app, or on the Chase website after you log in.
The fastest route is usually your debit card. Look at the bottom left of the front of the card — you'll see a series of numbers. The account number is the middle set of digits, between the routing number on the left and the check digit on the right. It's typically printed smaller than the card number itself.
If you don't have your card handy, a check works just as well. The account number appears at the bottom center of the check, after the routing number and before the check number on the right.
Key Takeaways
- Your Chase account number is a 10-digit code printed on the bottom left of your debit card, between the routing number and check digit.
- Checks display your account number at the bottom center, making them a reliable backup if your card is lost or unavailable.
- You can view your account number instantly in the Chase mobile app or on Chase.com after logging in under account details.
- Never share your full account number with anyone who contacts you first — Chase will never ask for it by phone or email.
Finding your account number in the Chase app or online
Open the Chase mobile app or go to Chase.com and sign in with your username and password. On the app, tap the account you want to view — it will show your account type (checking or savings) and the last four digits of the account number right on the main screen.
To see the full 10-digit number, tap "Account Details" or the gear icon. The complete account number will display there. On the website, click "Accounts" or "Account Summary," select the account, and look for "Account Number" in the details section — it's usually near the top.
This method is useful if you need to verify which account is which (checking versus savings) or if you're setting up a transfer and want to confirm the number before you enter it.
What to do if you can't locate your account number
If you've lost your card, don't have checks, and can't access online banking, call Chase customer service at the number on the back of your card or at 1-800-935-9935. Have your Social Security number, date of birth, and a photo ID ready. They'll verify your identity and read your account number to you over the phone.
If you're locked out of online banking, use the "Forgot Username" or "Forgot Password" link on Chase.com to regain access. You'll answer security questions or verify your identity through your phone number or email. Once you're back in, your account number is visible immediately.
Why you need your account number and when to use it
Your account number is required for setting up direct deposit, arranging wire transfers, paying bills through Chase Bill Pay, or giving someone permission to deposit money into your account. It's also needed if you're moving money between your own Chase accounts or linking a Chase account to an external bank.
You may also need it to dispute a transaction, set up automatic payments to creditors, or provide proof of account ownership to an employer or government agency. Keep it separate from your debit card number — they are different numbers that serve different purposes.
Protecting your account number from fraud
Your account number alone cannot be used to withdraw money or make purchases, but it can be used to set up unauthorized transfers or bill payments if someone has access to your online banking login. Never share your account number with anyone who calls or emails you first, even if they claim to be from Chase.
Chase will never ask for your account number, password, or Social Security number by phone or email. If someone contacts you claiming to be from Chase and asks for these details, hang up and call the number on the back of your card to verify whether the contact was real.
If you believe your account number has been compromised, log into Chase.com or call customer service immediately. They can monitor your account for suspicious activity and issue you a new debit card if needed.
The difference between your account number and other Chase numbers
Your Chase account number (10 digits) is different from your routing number (9 digits), your debit card number (16 digits), and your customer ID. The routing number identifies Chase as your bank and is the same for all Chase customers in your region. Your debit card number is unique to that card only and changes if you get a replacement card. Your customer ID is a separate identifier used for some Chase services.
When you're setting up direct deposit or a wire transfer, you'll need both your account number and your routing number. When you're making a purchase or payment online, you use your debit card number instead. Knowing which number to use for which task prevents delays and mistakes.
Frequently Asked Questions
Can someone withdraw money from my account if they have my account number?
Not directly. Your account number alone doesn't allow someone to make purchases or ATM withdrawals. However, they could potentially set up unauthorized transfers or bill payments if they also have access to your online banking login. Keep your account number and password separate and secure.
Is my account number the same as my customer ID?
No. Your customer ID is a separate number Chase uses to identify you as a customer across all your accounts and services. Your account number identifies a specific checking or savings account. You can find your customer ID in your online banking profile under "Account Details" or "Profile Settings."
What's the routing number and where do I find it?
Your routing number is a 9-digit code that identifies Chase as your bank and your region. It appears on the bottom left of your checks, before your account number. You can also find it on Chase.com or by calling customer service. You need both your routing number and account number for direct deposit and wire transfers.
Do I need my account number to pay a bill through Chase Bill Pay?
No. When you set up a bill payment through Chase Bill Pay, you enter the payee's information, not your own account number. Chase uses your account number internally to debit the payment from your account. You only need your account number if you're giving someone else permission to deposit money into your account.
What should I do if I see an unfamiliar transaction on my account?
Log into Chase.com or the mobile app and report it immediately through the "Report Fraud" or "Dispute a Transaction" option. You can also call the number on the back of your card. Chase will investigate and may issue a temporary credit while they verify the transaction. Document the date, amount, and merchant name before you report it.
