Your bank account number is printed on the bottom left of your checks, in your bank's mobile app, and on statements mailed to you
The easiest place to look is the bottom of a check from your account. The account number appears after the routing number — it's the longer string of digits, usually 10 to 12 numbers. If you don't have checks handy, log into your bank's website or mobile app and look for "Account Details" or "Account Information." Your statement — whether paper or digital — also shows the account number near the top.
If you need the number right now and can't access any of those, call your bank's customer service line. The number is on the back of your debit card or on your bank's website. Have your Social Security number and a form of ID ready, because the bank will verify your identity before giving out account information over the phone.
Key Takeaways
- Your account number appears on the bottom left of checks, after the routing number, and is typically 10 to 12 digits long.
- Bank statements — both paper and online — display your account number in the account details section near the top.
- Your bank's mobile app shows your account number under Account Details or Account Information without requiring a phone call.
- If you cannot locate it through these methods, call your bank's customer service line with your ID ready for verification.
Finding it on a check
Look at the bottom of any check from your account. You'll see three groups of numbers separated by colons or vertical lines. The first group is the routing number (nine digits). The second group is your account number. The third is the check number.
The account number is always the middle group and is usually longer than the routing number — often 10 to 12 digits, though some banks use different lengths. Write it down carefully, because a single digit wrong will cause a payment or deposit to fail.
Checking your online banking or app
Log into your bank's website or open the mobile app and navigate to the account overview or dashboard. Most banks display your account number prominently under "Account Details," "Account Information," or "My Accounts." Some banks require you to click on the specific account to see the full number.
The app method is often fastest because you don't have to wait for mail or dig through old checks. You can also take a screenshot or copy the number directly into a form or email if you need to send it somewhere.
Looking at your bank statement
Paper statements and electronic statements both show your account number. On a paper statement, it usually appears in the upper left or upper right corner, near your name and address. On an online statement (sometimes called an eStatement), look at the top of the document — the account number is typically listed alongside the routing number.
If you've misplaced recent statements, you can often download past statements from your online banking portal. Most banks keep at least 12 months of statements available for download.
Calling your bank directly
If you can't find your account number through any of the above methods, call your bank's customer service number. You'll find this number on the back of your debit card, on your bank's website, or in any statement you have on file.
Be ready to provide your Social Security number, date of birth, and a form of ID to verify your identity. The bank will not give out account information to someone who cannot prove they own the account. Once verified, the representative can read your account number to you over the phone or send it to you via secure message in your online banking portal.
What to do if your account number doesn't match
If you're trying to set up a direct deposit or make a transfer and the account number you found doesn't work, double-check that you copied it correctly. A single digit error will cause the transaction to fail or go to the wrong account.
Verify the number against at least two sources — your check, your statement, and your app, for example. If all three match and the transaction still fails, contact your bank. There may be a hold on the account, a recent account closure, or a technical issue on the receiving end that's preventing the deposit from going through.
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. The account number is what's used for direct deposits, wire transfers, and ACH payments. Your card number is for swiping or entering online purchases.
Can I find my account number on a mobile deposit receipt?
Yes. If you've used mobile deposit through your bank's app, the receipt or confirmation screen often displays your account number. You can also take a screenshot of the confirmation for your records.
What if I have multiple accounts at the same bank?
Each account has its own unique account number. Make sure you're looking at the statement or check for the specific account you need. If you log into your app, you can usually switch between accounts at the top of the screen to see each account's number separately.
Do I need to give my account number to receive a direct deposit?
Yes. To set up direct deposit for payroll, tax refunds, or government payments, you'll need to provide both your routing number and your account number. The employer or agency uses both to deposit money into the correct account at the correct bank.
