Your account number is printed on the bottom left of your checks, in your bank's mobile app, and on paper statements mailed to you
The easiest place to look is the bottom of a check from your checking account. The account number appears after the routing number and before the check number. If you don't have checks handy, log into your bank's website or mobile app — your account number shows on the account overview page, usually near the account name. You can also call your bank's customer service line and give them your name and Social Security number to confirm it.
Paper statements mailed to your home also display your account number at the top or in the account details section. If you've switched to paperless statements, you can still download past statements from your bank's website and find the number there. Some banks print it on debit cards as well, though not all do.
Key Takeaways
- Your account number appears on the bottom left of checks, right after the routing number.
- Bank websites and mobile apps show your account number on the main account page without needing to log into anything extra.
- Calling your bank's customer service line and providing your name and Social Security number will get you the number over the phone.
- Paper statements and downloadable PDFs from your bank's website both display the account number in the account details section.
Finding it on checks
Look at the bottom of any check from your account. You'll see a series of numbers printed in magnetic ink. The first set is your routing number (nine digits), the second set is your account number (typically 10 to 12 digits), and the third is the check number. The account number is the middle group.
If you're looking at an old check, the account number is still valid — it doesn't change when you order new checks. You don't need a current check; any check from that account will show the same number.
Checking your bank's website or app
Log into your bank's website or open the mobile app on your phone. Once you're signed in, go to the main account page or dashboard. Most banks display your account number prominently near the account name, balance, or account type. You may see it labeled as "Account Number" or "Account #."
If you don't see it on the main page, look for an "Account Details" or "Account Information" link. Some banks hide it behind a settings menu or require you to click on the specific account you're asking about if you have multiple accounts.
Calling your bank directly
Pick up the phone and call the customer service number on the back of your debit card or on your bank's website. Tell the representative you need your account number. They'll ask you to verify your identity — usually by providing your name, date of birth, and Social Security number, or by answering security questions you set up when you opened the account.
This method works even if you've lost your checks and don't have online access. The call typically takes a few minutes, and the representative can also confirm which type of account it is (checking, savings, money market) if you need that information too.
Locating it on paper statements
If you receive paper statements in the mail, your account number is printed on every one. Look at the top of the statement near the account name, or scan the account details section — usually on the first page. The number format is the same as what appears on your checks.
You can also request an old statement from your bank if you've thrown yours away. Most banks keep statements available for download through their website for at least seven years. Log in, find the statements section, and download a PDF from any month — the account number will be there.
What to do if you can't find it
If none of these methods work — for example, if you've just opened an account and haven't received checks or statements yet — contact your bank immediately. Call the number on your debit card or visit a branch in person with your ID. They can provide the number on the spot and answer any questions about your account.
Never share your account number with someone who calls or emails you claiming to be from your bank. Real banks will never ask for your account number unsolicited. If you're uncertain whether a caller is legitimate, hang up and call your bank's official number from the back of your card.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank (nine digits), while your account number identifies your specific account at that bank (usually 10 to 12 digits). Both appear on checks, but in different positions. You need both to set up direct deposit or wire transfers.
Can I use an old check to find my account number?
Yes. Your account number doesn't change, so any check from your account — even one from years ago — will show the correct number. The routing number stays the same too, unless your bank merges with another bank.
What if I have multiple accounts at the same bank?
Each account has its own number. If you have a checking account and a savings account, they'll have different account numbers but the same routing number. Log into your bank's app and select the specific account you need — the number will display for that account only.
Do I need my account number to use my debit card?
No. Your debit card works with just the card number, expiration date, and CVV. You only need your account number for things like setting up direct deposit, receiving wire transfers, or paying bills by bank transfer.
