The fastest way to find your account number
Your checking account number is printed on the bottom left of every check you write, right after the routing number. If you have a checkbook in front of you, open it and look at the first check. You will see nine digits (the routing number), then your account number, which is usually 10 to 12 digits long. That is the number your bank uses to identify your specific account.
If you do not have checks or prefer not to dig through a drawer, your bank's website or mobile app shows your account number in seconds. Log in, go to your account details or account summary, and the number will be listed there alongside your balance and recent transactions. Most banks display it prominently so you can copy it without calling anyone.
Your bank statement — whether you get it by mail or email — also lists your account number at the top. If you have a recent statement saved or can access it through your bank's portal, that is another reliable place to look.
Key Takeaways
- Your checking account number appears on the bottom left of any check you have, printed after the routing number.
- Log into your bank's website or app and navigate to account details to see your account number without leaving home.
- Your bank statement, whether mailed or emailed, displays your account number at the top of the document.
- If you cannot locate it through these methods, call your bank's customer service line and have your ID ready to verify your identity.
Finding it on your bank's website or app
Most banks make this straightforward. After you log in, look for a section labeled "Account Details," "Account Information," or "My Accounts." Click or tap that section and your account number will be displayed. Some banks put it right on the dashboard when you first log in; others require one extra click.
If you use your bank's mobile app, the process is the same. Open the app, log in, and navigate to your account summary. Your account number is usually visible there, and many apps let you tap it to copy it to your clipboard so you can paste it elsewhere without typing it out.
If you cannot find it after looking in these places, your bank's website usually has a help section or FAQ that walks you through the steps for your specific bank. Alternatively, you can call the customer service number on the back of your debit card.
Reading it from a check
The bottom of a check contains three sets of numbers separated by vertical lines. From left to right: the routing number (nine digits), your account number (usually 10 to 12 digits), and the check number (three to four digits). Your account number is the middle set.
The account number on a check is always the same for your checking account, no matter which check you look at. If you have multiple checking accounts at the same bank, each one will have a different account number, and each checkbook will reflect the correct number for that account.
Getting it from your bank statement
Open any bank statement you have received — whether it arrived by mail or you downloaded it as a PDF from your bank's website. Look at the top of the document. Your account number is typically printed there, often labeled as "Account Number" or "Acct #." It will be the same number that appears on your checks.
If you receive statements by email, search your email for "statement" or the name of your bank, find a recent one, and download the PDF. The account number will be in the same place. Many banks also let you access past statements through their website portal, so you can pull up any month you need.
Calling your bank if you cannot find it
If none of these methods work — you have no checks, cannot access your online account, and do not have a statement — call the customer service number on the back of your debit card or the number listed on your bank's website. Have your ID ready and be prepared to answer security questions to verify you are the account holder.
The bank will confirm your identity and then read your account number to you over the phone. Write it down or ask them to repeat it so you have it correct. This route takes longer than the others, but it is reliable if you are locked out of your online account or have lost access to your checks and statements.
Why you need your account number
Your account number is required when you set up direct deposit, arrange a wire transfer, authorize an automatic payment, or give someone else permission to deposit money into your account. It is also what you need when you contact your bank about a specific transaction or dispute on your account.
Your account number is not sensitive information in the way your PIN or password is — it is printed on every check you write and visible to anyone who receives a payment from you. However, you should not share it with people you do not trust, and you should never give it to someone who calls you claiming to be from your bank unless you initiated the call.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank or credit union; your account number identifies your specific account at that bank. Both appear on your checks, but they are different numbers. The routing number is always nine digits; your account number is usually 10 to 12 digits.
Can I find my account number on my debit card?
No, your debit card does not display your account number. It shows your card number, which is different. To find your account number, check a check, your bank statement, or log into your online banking.
What if I have multiple checking accounts at the same bank?
Each account has its own unique account number. When you log into your bank's website or app, you will see all your accounts listed separately, each with its own number. Your checkbooks will also reflect the correct account number for each account.
Is it safe to share my account number?
Your account number is not secret — it appears on every check you write. However, only share it with people or organizations you trust, such as your employer for direct deposit or a utility company for automatic payments. Never give it to someone who calls you unsolicited.
