Where to find your account number in online banking
Your bank account number appears in your online banking 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." Most banks display your full account number right there, though some mask it for security and show only the last four digits on the main screen.
If you cannot find it on the main dashboard, check the account statements section. Your account number is printed on every statement your bank generates — look at the top or header of any recent statement PDF or document. You can also find it on checks if you have them; the account number is the middle set of digits printed at the bottom of the check, between the routing number on the left and the check number on the right.
Some banks require you to click into individual account settings or a "View Details" button to see the full number. If your bank's app only shows the last four digits, try logging in through the website instead — the website version often displays more complete information.
Key Takeaways
- Your account number is visible in your bank's online portal under "Accounts" or "Account Details," though some banks mask it and show only the last four digits on the main screen.
- Every bank statement includes your full account number at the top or in the header section, and you can download or view past statements through your online banking portal.
- Physical checks display your account number as the middle set of digits at the bottom, between the routing number and check number.
- If you cannot locate it online, call your bank's customer service line — they can confirm your account number over the phone after verifying your identity.
Checking your statement for the account number
The fastest way to find your account number if you do not want to dig through your online portal is to pull up a recent bank statement. Log into your online banking and navigate to "Statements," "History," or "Documents." Download or view any statement from the past few months — your account number is printed near the top, usually in the header or on the first line of the document.
If you have paper statements mailed to you, grab the most recent one from your files. The account number will be printed clearly at the top of the page. This method works even if you have not set up online banking yet, as long as you have received at least one statement in the mail.
Using your checks to locate the account number
If you have a checkbook, your account number is printed on every check. Look at the bottom of the check — you will see three sets of numbers separated by vertical lines or special characters. The first set is your bank's routing number, the middle set is your account number, and the third set is the check number itself.
The account number on a check is typically 10 to 12 digits long, though this varies by bank. Write down the middle set of numbers, and that is your account number. This method works whether or not you have online banking set up.
What to do if your online portal does not show the full number
Many banks hide your full account number on their mobile apps or main dashboard for security reasons, displaying only the last four digits instead. If you need the complete number and your app only shows a partial view, try logging in through your bank's website on a computer — the website version often displays more information than the mobile app.
Look for a "View Full Account Number" link or button, or click into the account settings or details page. Some banks require you to verify your identity a second time before showing the full number. If the website still does not display it, contact your bank directly — customer service can read your account number to you over the phone after confirming your identity with security questions or other verification.
Contacting your bank if you cannot find it online
If you do not have access to statements, checks, or a working online banking account, call your bank's customer service number. This number is on the back of your debit card, on your bank's website, or in your account paperwork. Have your identification ready — the bank will ask you to verify your identity before providing your account number.
Be prepared to answer security questions about your account, provide your Social Security number, or confirm recent transactions. Once verified, the representative will give you your account number over the phone. You can also visit a branch in person with a photo ID and ask a teller to provide your account number.
Why banks sometimes mask account numbers
Banks hide full account numbers on mobile apps and public-facing screens as a security measure. If your phone is lost or stolen, or if someone looks over your shoulder, they see only the last four digits rather than your complete account number. This reduces the risk that someone could use your account number for unauthorized transfers or payments.
The full number is still stored securely in your account and is available to you when you need it — through statements, checks, the website, or by calling the bank. This masking does not prevent you from accessing your own information; it just requires one extra step to view sensitive details.
Frequently Asked Questions
Is it safe to share my account number online?
Your account number alone cannot be used to withdraw money or make purchases — most transactions also require your routing number, PIN, or other verification. However, do not share it with unknown websites or people. Share it only with your employer for direct deposit, with your bank, or with established companies you trust. Never enter it on a website unless you initiated the contact.
What if I see multiple account numbers in my online banking?
If you have more than one account with the same bank — such as a checking account and a savings account — each one has its own account number. Make sure you are looking at the correct account. The account type is usually labeled next to the number, so you can tell them apart.
Can I change my account number?
You cannot change your account number yourself. If you are concerned about fraud or security, contact your bank and explain the situation. In rare cases, the bank may close your current account and open a new one with a different number, but this is not a standard option for routine requests.
Do I need both my routing number and account number?
Many transactions require both numbers — direct deposit, wire transfers, and automatic bill payments typically need both. Your routing number identifies your bank; your account number identifies your specific account within that bank. Statements and checks show both numbers, so you can find them together.
