Your Chase account number is printed on the bottom left of your checks, visible in the Chase mobile app, and available by calling customer service
The fastest way to locate your account number depends on what you have access to right now. If you have a checkbook, look at the bottom left corner of any check — the account number appears after the routing number and before the check number. If you use the Chase mobile app or online banking, log in and open your account details; the account number displays prominently on the account summary page. If you need it immediately and don't have checks or online access, call Chase customer service at the number on the back of your debit or credit card, and they'll read it to you after verifying your identity.
Your account number is a string of 10 to 12 digits unique to your specific account. You'll need it for wire transfers, setting up direct deposit, authorizing automatic bill payments, and providing proof of account ownership to third parties like employers or loan servicers.
Key Takeaways
- Your Chase account number is the middle set of numbers on the bottom of a check, between the routing number and the check number.
- The Chase mobile app and online banking portal both display your account number on the account summary or details page.
- Chase customer service can provide your account number over the phone if you call the number on your card and verify your identity.
- Your account number is different from your routing number; you may need both for wire transfers or setting up direct deposit.
- If you have multiple Chase accounts, each one has its own unique account number.
Reading the numbers on a check
A Chase check has three sets of numbers printed along the bottom in magnetic ink. From left to right, they are: the routing number (nine digits), your account number (typically 10 to 12 digits), and the check number (four to six digits). The account number is always in the middle. This layout is the same across all Chase checks, whether you have a basic checking account or a premium product.
If your checks are old or the ink has faded, the numbers may be hard to read. In that case, use one of the other methods instead of trying to guess. Writing down an incorrect account number can cause transfers to fail or reach the wrong account. If you've ordered new checks recently, they should have clear, dark printing that's easy to read.
Finding it in the Chase app or online banking
Open the Chase mobile app or go to chase.com and log in with your username and password. On the home screen or dashboard, you'll see a list of your accounts. Tap or click on the checking or savings account you need. The account number appears on the account details page, usually near the top, alongside the account type and current balance. You can also find it by selecting "Account Details" or "Account Information" from the menu.
If you have trouble locating it, look for a section labeled "Account Number" or "Account Details." Some versions of the app display it prominently; others require you to scroll down slightly. The number is always there — it's not hidden behind a security setting. If you're using a shared or joint account, both account holders can see the same account number in their own logins.
Calling Chase customer service
The phone number for Chase customer service is printed on the back of your debit card or credit card. Call that number and follow the prompts to speak with a representative. They will ask you to verify your identity by providing your Social Security number, date of birth, or answers to security questions you set up when you opened the account.
Once verified, the representative will read your account number to you. This method works even if you don't have your card, checks, or online access — as long as you can answer the security questions. Wait times vary by time of day; calling early in the morning or mid-week often means shorter holds. Have a pen and paper ready so you can write down the number accurately.
Understanding routing number versus account number
Your Chase routing number and account number are two different things, and you may need both for certain transactions. The routing number identifies which Chase branch or processing center handles your account — it's the same for all Chase customers in your region. Your account number identifies your specific account within Chase's system. When you set up direct deposit or a wire transfer, you'll usually need to provide both.
The routing number is the first set of nine digits on the bottom of a check. If you're unsure which is which, remember: routing number comes first (left), account number comes second (middle). For Chase, the routing number depends on your state and the branch where you opened the account, but you can also find it on the Chase website or by calling customer service.
What to do if you can't find your account number
If you've checked your checks, the app, and online banking and still can't locate it, contact Chase directly. Call the number on your card, visit a Chase branch in person with your ID, or use the secure message feature in online banking to ask for your account number. Chase will not send account numbers through unsecured email, so don't ask them to email it to you — they'll direct you to retrieve it through the app or by phone instead.
If you're trying to find the account number for someone else's account (a joint account holder, for example), that person must be present or must have authorized you to access the account. Chase will not release account information to unauthorized parties, even if you're related. If you're a parent trying to access a minor's account, bring documentation showing you're the account owner or authorized guardian.
Keeping your account number secure
Once you have your account number, treat it like sensitive financial information. Don't share it in emails, texts, or over the phone unless you initiated the contact and you're certain you're speaking with your bank or a trusted organization. Scammers sometimes call claiming to be from Chase and ask for your account number — legitimate Chase representatives will never ask for it this way. If someone calls you asking for your account number, hang up and call Chase directly using the number on your card.
Write down your account number and keep it in a secure place at home, separate from your checks and cards. You may need it for tax purposes, loan applications, or setting up automatic payments. If you suspect your account number has been compromised or used fraudulently, contact Chase immediately — they can close the account and issue a new one with a different number.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your debit or credit card number is different from your bank account number. The card number is printed on the front of the card; the account number is on the bottom of your checks or in your online banking portal. Some transactions require the account number, while others require the card number.
Can I use my account number to make online purchases?
No. Online purchases require your card number, expiration date, and CVV. Your account number is used for bank-to-bank transfers, direct deposit, and bill payments — not for retail or online shopping.
What if I have multiple Chase accounts?
Each account has its own unique account number. When you log into online banking or the app, you'll see all your accounts listed separately, each with its own number. Make sure you're using the correct account number for the transaction you're making.
Do I need my account number to call Chase customer service?
No. When you call, Chase will ask you to verify your identity using your Social Security number, date of birth, or security questions. Once verified, they can pull up your account and provide the number if you need it.
Will Chase send my account number by email or text?
Chase will not send account numbers through email or text for security reasons. You can retrieve it through the mobile app, online banking, by calling customer service, or by visiting a branch in person.
