Your bank account number is on your checks, your online banking portal, and your bank statements — you do not need to visit a branch or call customer service to find it.
The fastest way is to log into your bank's website or mobile app. Once you are signed in, your account number usually appears on the dashboard or in an "Account Details" or "Account Information" section. Some banks show it when ready; others require you to click through to a specific account view.
If you have a checkbook, look at the bottom left of any check. The account number is the second set of numbers, printed between the routing number on the left and the check number on the right. The format is always the same on every check from that account.
Bank statements — whether you receive them by mail or read them as PDFs — print your account number near the top, usually next to the account holder's name or in a header section labeled "Account Information."
Key Takeaways
- Your account number appears in your online banking portal under account details, usually accessible within seconds of logging in.
- The second set of numbers at the bottom of any check is your account number, positioned between the routing number and check number.
- Bank statements printed or emailed to you display your account number in the header or account information section.
- You do not need to contact your bank or visit a branch to retrieve your account number if you have access to any of these sources.
Finding your number through online banking
Log into your bank's website or app using your username and password. The account number is usually visible on the main dashboard or home page, often displayed prominently next to your account balance.
If it is not when ready visible, look for a menu option labeled "Accounts," "Account Details," "Account Information," or "My Accounts." Clicking this will open a page showing all your accounts with their numbers. Some banks require you to click on a specific account to see its full number; others show it in a list view.
Mobile apps often hide the full account number by default for security. If you see only the last four digits, tap or click on the account name or a "View Details" button to reveal the complete number.
Reading your account number from a check
Open any check from your checkbook. At the bottom of the check, you will see three groups of numbers separated by vertical lines or special symbols.
The first group (on the far left) is your bank's routing number. The second group is your account number — this is what you need. The third group on the right is the individual check number. Your account number on a check is typically 10 to 12 digits long, though this varies by bank.
Every check from the same account will have the same account number printed at the bottom. If you have multiple accounts at the same bank, each will have a different account number, but the routing number stays the same.
Locating your account number on statements
Bank statements arrive either by mail or as email attachments, depending on how you set up your account. Open the statement and look at the top section, usually labeled "Account Information" or "Account Details."
Your account number will be printed there, often next to your name or account type (such as "Checking" or "Savings"). If you receive statements by email as a PDF, use your PDF reader's search function to look for "Account Number" — this will take you directly to the line where it appears.
Statements are useful if you have lost your checkbook and do not have online banking access. You can request a copy of your most recent statement from your bank by phone or through your online portal.
What to do if you cannot access any of these sources
If you do not have checks, cannot log into your online account, and have not received a statement, contact your bank directly. You will need to verify your identity — typically by providing your Social Security number, date of birth, and the last four digits of the phone number or address on file.
Call the customer service number on the back of your debit card, or visit your bank's website to find the phone number for your local branch. Have your ID ready. The bank will confirm your identity and provide your account number over the phone.
Some banks also allow you to retrieve your account number through their website without logging in, by entering your Social Security number and other identifying information. Check your bank's website for a "Forgot Username" or "Account Information" section that may offer this option.
Why you might need your account number
Your account number is required for direct deposits, wire transfers, automatic bill payments, and setting up transfers between your accounts at different banks. It is also needed when you contact your bank about a specific transaction or account issue.
Your account number alone is not enough for someone to withdraw money from your account — they also need your routing number and typically additional verification. However, treat your account number as you would any other financial information: do not share it with unknown callers or in unsecured emails.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is printed on the front of the card and is different from your account number. Your account number is what the bank uses internally to identify your account; your card number is what merchants use to process payments. You can have the same account number for years, but your debit card number changes when you get a new card.
Can someone access my account with just my account number?
Your account number alone is not enough to withdraw money or make unauthorized transfers. A person would also need your routing number, and most banks require additional verification such as a PIN, password, or security questions. However, do not share your account number with people you do not trust.
What if my bank does not show the account number in the app?
Some banks hide the full account number in their mobile app for security. Try logging into the website version instead of the app, or contact your bank's customer service. You can also find the number on a check or statement if you have either available.
Do I need both my routing number and account number to receive a direct deposit?
Yes. Your employer or the organization sending the deposit will ask for both your routing number and account number. The routing number tells the system which bank to send the money to; the account number tells the bank which account within that bank should receive it.
