Your account number is printed on the bottom left of every check you have, and in your online banking portal under account details or account information
The fastest way is to look at a physical check from your checkbook. The account number appears at the bottom of the check, after the routing number and before the check number. It is usually 8 to 12 digits long, though the length varies by bank.
If you do not have checks, log into your bank's website or mobile app. Most banks display your account number on the dashboard or home screen. If not, look for a section labeled "Account Details," "Account Information," "My Accounts," or "Account Summary." Your full account number will be there, sometimes with the last four digits visible and the rest masked with asterisks for security.
Your bank statement—whether paper or digital—also shows your account number at the top or in a header section. If you receive statements by mail, it is printed on the front. If you view statements online, it appears near the account name or in the document header.
Key Takeaways
- Your account number is on the bottom of any check you own, printed between the routing number and the check number.
- Log into your bank's website or app and look for "Account Details" or "Account Information" to see your full account number.
- Paper and digital bank statements both display your account number in the header or top section.
- If you cannot find it online or on paper, call your bank's customer service line—the number is on the back of your debit card.
Finding your account number in online banking
The location varies slightly by bank, but the process is the same. Sign in to your bank's website or app, then look for your accounts list. Most banks show a summary view with all your accounts—checking, savings, money market, and so on. Click or tap on the specific account you need the number for.
A details page will open. Your account number is usually displayed prominently near the top, sometimes labeled "Account Number" or "Account #." Some banks show the full number; others show only the last four digits on the main screen and require you to click a "View Full Account Number" button or link. If you do not see it on the first screen, look for a tab or menu option that says "Account Details," "Account Settings," or "More Information."
If your bank's app or website is unfamiliar to you, the help or search function can point you to the right page. Type "account number" into the search box, and the bank will show you where to find it.
Reading your account number from a check
At the bottom of every check, you will see three sets of numbers separated by vertical lines or special symbols. From left to right, they are: the routing number (9 digits), your account number (usually 8 to 12 digits), and the check number (usually 4 digits).
The account number is the middle set. Write it down carefully—a single digit wrong will cause a transfer or payment to fail or go to the wrong account. If you are reading it aloud to someone, spell out each digit to avoid confusion between similar-sounding numbers like 5 and 9.
What to do if you cannot locate your account number
If you have no checks, cannot access online banking, and do not have a recent statement, call your bank directly. The phone number is on the back of your debit card, or you can search for "[Bank Name] customer service" online. Have your identification ready—the bank will ask for your Social Security number, date of birth, or other personal information to verify you are the account holder.
You can also visit a branch in person with a photo ID. A teller can print your account number for you in seconds. This is often the fastest option if you need the number when ready and a branch is nearby.
Why banks mask your account number online
Many banks show only the last four digits of your account number on the main dashboard or in notifications for security reasons. This protects you if someone gains temporary access to your phone or computer—they cannot see your full account number without logging in and navigating to the account details page.
When you need to share your account number with someone—a payroll department, a creditor, or another bank—you can safely do so. Your account number alone, without your routing number, cannot be used to withdraw money or open new accounts. However, your account number plus your routing number together can be used to set up transfers, so only share both pieces of information with people and organizations you trust.
Account numbers for different account types
Each account you hold at a bank has its own account number. If you have a checking account and a savings account at the same bank, they have different account numbers. The same is true for money market accounts, certificates of deposit, and any other account type.
When you set up a transfer or direct deposit, make sure you are using the account number for the specific account you want the money to go into. Using the wrong account number will send the money to the right bank but the wrong account, and you will have to contact the bank to correct it.
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 at the bottom of your checks, with the routing number first and the account number second. You need both to set up transfers or direct deposits.
Can someone use my account number to steal money?
Your account number alone cannot be used to withdraw money or open new accounts. However, combined with your routing number, it can be used to set up transfers or recurring payments. Only share both numbers with organizations you trust, like your employer or a creditor.
What if I see a different account number on my statement than on my checks?
This is rare but can happen if your account was recently transferred or merged. Contact your bank to confirm which number is current. Use the number from your most recent statement or online banking portal.
Do I need my account number to use my debit card?
No. Your debit card has its own card number printed on the front. You do not need your account number for everyday purchases or ATM withdrawals. You only need your account number for transfers, direct deposits, or when setting up payments from your account.
