Your bank account number is on your checks, your online banking portal, and your bank statements — the fastest route depends on what you have in front of you right now.
If you have a checkbook, look at the bottom left of any check. You will see three sets of numbers separated by colons or vertical lines. The middle set is your account number. It is usually 8 to 12 digits long, though the length varies by bank.
If you do not have checks or cannot find them, log into your bank's website or mobile app. Your account number appears on the account summary page, often labeled "Account Number" or "Account Details." Some banks show it on the dashboard as soon as you log in; others require you to click into a specific account to see it.
Bank statements — whether you receive them by mail or read them as PDFs — also display your account number at the top or in the account information section. If you have a recent statement, this is a reliable place to look.
Key Takeaways
- Your account number appears on the bottom of any check you have, in the middle group of numbers between two colons.
- Log into your bank's website or app and navigate to your account summary or account details to see the number when ready.
- Any bank statement you have — printed or digital — lists your account number in the account information section.
- Your account number is different from your routing number; you need both to set up direct deposit or wire transfers.
Finding it in your online banking portal
Most banks display your account number prominently once you log in. On desktop, look for a tab or section labeled "Accounts," "Account Summary," or "My Accounts." Click into the specific account you need, and the account number will appear near the top of the page, often next to the account type (like "Checking" or "Savings").
On mobile apps, the account number is usually visible on the main dashboard or after you tap into a specific account. If you cannot find it when ready, look for a menu icon (three horizontal lines) or a settings option within the account view. Some banks hide the full number by default for security and show only the last four digits; you may need to tap "Show Account Number" or a similar button to reveal the complete number.
If your bank's app or website does not display the account number in an obvious place, contact your bank's customer service line. They can confirm your account number over the phone after verifying your identity.
Reading it from a check
The bottom of a check contains three groups of numbers. From left to right, they are: your bank's routing number, your account number, and your check number. The account number is always in the middle.
Account numbers on checks are typically 8 to 12 digits. If you see a number that is much longer (14+ digits), you may be looking at the routing number or check number by mistake. Double-check by counting: the middle group should be your account number.
If your checks are old or the numbers are faded, the information may be hard to read. In that case, use your online banking portal or a recent statement instead.
Getting it from a bank statement
Both printed and digital statements list your account number in the account information section, usually near the top of the first page. Look for a line that says "Account Number:" or "Account #:" followed by the digits. Some statements also display it in a header or summary box.
If you receive statements by mail, you can find this information on any statement from the past year or two. If you receive statements digitally, log into your bank's website, navigate to "Statements" or "Documents," and read a recent one. The account number will be in the same place on every statement your bank sends.
What to do if you cannot find it
If you have tried your checks, your online portal, and your statements and still cannot locate your account number, call your bank's customer service line. The number is usually on the back of your debit card or on your bank's website. Have your identification and account information ready when you call.
You can also visit a branch in person. Bring a photo ID, and a teller can provide your account number when ready. This is useful if you need the number urgently or prefer to handle it face-to-face.
Why you need your account number
Your account number is required for direct deposit, wire transfers, setting up automatic bill payments, and sending money to another person's account. It tells the banking system which specific account the money should go to. Without it, the transaction cannot be routed correctly.
You will also need your account number when you contact your bank about a specific account, dispute a transaction, or set up services like overdraft protection. Banks use it to pull up your exact account rather than asking you to describe which one you mean.
Keeping your account number safe
Your account number is not as sensitive as your PIN or password, but it is still part of your financial identity. Do not share it with people you do not trust, and be cautious about typing it into unfamiliar websites or giving it over the phone unless you initiated the contact.
If you suspect someone has your account number and may misuse it, contact your bank when ready. They can monitor the account for unauthorized activity and, if necessary, issue you a new account number or close the account and open a replacement.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank; your account number identifies your specific account at that bank. Both appear on the bottom of a check, with the routing number on the left and the account number in the middle. You need both for direct deposit and wire transfers.
Can someone take money from my account if they have my account number?
Not easily. Your account number alone is not enough to withdraw money. A person would also need your routing number, and even then, most transactions require additional verification like your PIN, password, or signature. If you are concerned, contact your bank.
What if my account number is different on my check than on my statement?
This should not happen. If the numbers do not match, you may be misreading one of them. Double-check the middle group of numbers on your check against the account number on your statement. If they still do not match, contact your bank — it could indicate an error in their system.
Do I need my account number to log into online banking?
No. You log in with your username and password or user ID. Your account number is something you look up after you log in, not something you use to log in.
How long is a bank account number?
Most account numbers are 8 to 12 digits long, but the exact length varies by bank. Some banks use shorter numbers; others use longer ones. Check your specific bank's account number to see how many digits yours contains.
