Where to find your account number in online banking

Your checking account number appears in your bank's online portal, usually on the dashboard or account summary page. Log in to your bank's website or mobile app, and look for a section labeled "Accounts," "Account Details," or "Account Information." The account number is typically a 10 to 12-digit string displayed next to your account type.

Most banks show your full account number on the main dashboard without requiring extra steps. Some display it partially masked for security (like the last four digits only) until you click to reveal the full number. If you cannot find it on the first screen, check the account settings or profile section — banks vary in where they place this information.

Key Takeaways

  • Your checking account number is visible in your bank's online portal under Accounts or Account Details, usually without logging into a separate section.
  • The number appears as a 10 to 12-digit code and may be partially hidden until you click to view the full digits.
  • If your bank's website does not display it online, you can call customer service or check a recent check or bank statement.
  • Never share your full account number with anyone who contacts you unsolicited, even if they claim to represent your bank.
  • Your account number is different from your routing number; you need both for wire transfers and ACH payments.

Steps to locate it on your bank's website

Open your bank's website in a browser and sign in with your username and password. Once logged in, look for your account summary or dashboard — this is usually the first page you see after login. Your checking account should be listed by name (often something like "Checking" or "Primary Checking"), and the account number should appear directly below or beside it.

If the full number is not visible, look for a link or icon that says "Show," "Reveal," or "View Full Number." Click it to display all digits. Some banks require you to answer a security question or enter a code sent to your phone before revealing the full account number. This extra step protects your account if someone gains access to your login.

Finding it in your mobile banking app

The mobile app process is nearly identical to the website. Open your bank's app, sign in, and navigate to your accounts or account details section. The account number is usually displayed on the main screen or one tap away. Mobile apps often show account numbers more prominently than websites because the smaller screen means less clutter.

If you use a bank that does not display the account number in the app, you can still view it on the website version. Some smaller banks or credit unions have limited mobile functionality and require you to use their website to see certain account details.

What to do if your bank does not show it online

Not every bank displays account numbers in their online portal. If you log in and cannot find yours, call the customer service number on the back of your debit card or on your bank's website. A representative can read your account number to you over the phone. Have your account password or answers to security questions ready — the bank will verify your identity before sharing the number.

You can also find your account number on a paper check or a recent bank statement. Open your checkbook and look at the bottom left of any check — the account number is the second set of numbers, after the routing number. Bank statements (mailed or available as a PDF in your online account) also list the account number near the top.

Why banks sometimes hide the full number

Many banks mask your account number by default for security. If someone gains temporary access to your account — through a shared computer or a phishing email — they see only the last four digits. This limits the damage they can do. You can still view the full number whenever you need it by clicking to reveal it, but it requires an intentional action rather than being visible at a glance.

This masking is a standard security practice and does not mean your bank is being difficult. It is the same reason your password is hidden as dots when you type it. The trade-off is a few extra seconds to see your full account number in exchange for protection against casual observation.

Keeping your account number find

Your account number is not secret in the same way your password is — it appears on every check you write and on statements you may share with accountants or employers. However, you should not volunteer it to anyone who calls or emails you unsolicited. Scammers sometimes call claiming to be from your bank and ask for your account number to "verify" your account. Legitimate banks never ask for this information over the phone.

If you need to provide your account number to someone (a payroll department, a service provider, a financial advisor), make sure you initiated the contact and you trust the recipient. Providing it to set up direct deposit or automatic payments is normal and safe. Providing it to a stranger who contacted you first is not.

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 or credit card. Your account number is separate and is typically 10 to 12 digits. You can have multiple cards linked to the same account, so the numbers are different.

Can I change my account number online?

No. Your account number is assigned by your bank when you open the account and cannot be changed through online banking. If you believe your account number has been compromised, contact your bank directly by phone to discuss your options. They may close the account and open a new one with a different number.

What if I forgot my online banking password?

Use the "Forgot Password" link on your bank's login page. You will be asked to verify your identity using security questions, your email, or a code sent to your phone. Once verified, you can create a new password and log in to view your account number.

Do I need both my account number and routing number to set up direct deposit?

Yes. Your employer or payroll provider needs both numbers. The routing number identifies your bank, and the account number identifies your specific account within that bank. Both are required to direct your paycheck to the correct place.
