Your account number is printed on the bottom left of your checks, visible in your online banking portal, and available by calling your bank's customer service line.
The fastest way to find your account number depends on what you have access to right now. If you have a checkbook, look at the bottom of any check—the account number appears after the routing number and before the check number. If you're online, log into your bank's website or mobile app and look for "Account Details," "Account Information," or a similar section, usually found in the dashboard or under your profile. If you don't have checks or online access, call your bank's main number, give them your name and identification, and they'll read it to you.
Key Takeaways
- Your account number is printed on the bottom left of every check you have, right after the routing number.
- Online banking portals show your account number in the account details or dashboard section, accessible from any device.
- If you don't have checks or online access, call your bank's customer service line with your ID ready and they will provide it immediately.
- Some banks also print the account number on statements, debit cards, or in confirmation emails sent when you opened the account.
- Never share your full account number with anyone unless you initiated the contact and trust the recipient.
Finding it on a check
The bottom of a check contains three numbers in a specific order: routing number, account number, and check number. The account number is the middle one and is typically 10 to 12 digits long, though this varies by bank. It appears in the same spot on every check from your account.
If you have old checks from years ago, the account number will be the same as on your current checks—it doesn't change unless you close the account and open a new one. If you've misplaced your checkbook, any check you've written and kept a record of will have this information.
Viewing it online
Log into your bank's website or app using your username and password. Once you're logged in, look for a section labeled "Account Details," "Account Information," "My Accounts," or "Account Summary." This is usually on the main dashboard or accessible from a menu at the top or side of the page.
Click into the specific account you need the number for—if you have multiple accounts, each one will have its own account number. The account number will be displayed prominently, often alongside the routing number and account type. Some banks also show it in a format you can copy and paste, which is useful if you need to send it to someone.
Getting it by phone
Call your bank's main customer service number, which is usually on the back of your debit card or on your most recent statement. Have your Social Security number, date of birth, and a form of ID ready—the bank will ask for these to verify you're the account holder.
Tell the representative which account you need the number for if you have more than one. They'll read it to you over the phone. Some banks also offer automated phone systems where you can press buttons to navigate to account information without speaking to a person, though this varies by institution.
Other places the number appears
Bank statements, whether printed or digital, usually show your account number at the top or in a header section. If you receive paper statements in the mail, look at the first page. If you view statements online, they're typically in the same location as the online portal shows them.
Some banks print the account number on debit cards, though not all do—if yours does, it's usually on the front or back. Confirmation emails sent when you first opened the account may also contain it. If you've saved those emails, searching your inbox for "account number" or "account confirmation" may turn them up.
What to do if you can't find it
If you don't have checks, can't access online banking, and don't have a recent statement, the phone route is your most direct option. You'll need to verify your identity, which requires information only you would know—typically your Social Security number, date of birth, and the answers to security questions you set up when you opened the account.
If you've forgotten your online banking password, most banks have a "Forgot Password" link on the login page that will walk you through resetting it via email or text. Once you reset it, you can log in and find the account number yourself without calling.
Keeping your account number safe
Your account number, combined with your routing number, is enough for someone to set up automatic payments or transfers from your account. Don't share it with people you don't trust, and be cautious about typing it into websites unless you initiated the contact and recognize the organization.
If you need to give your account number to a business—to set up a direct deposit, pay a bill, or receive a refund—make sure you're communicating with them directly, not through a link or number they provided. Scammers sometimes pose as banks or businesses to collect account information.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is different from your account number. The card number is printed on the front of the card, while the account number appears on checks and in your online banking portal. Both are tied to the same account, but they're separate numbers.
Can I find my account number on a bank transfer receipt?
Usually yes. If you've sent or received a wire transfer or ACH transfer, the receipt or confirmation email often shows the account number that was used. Check your email for transfer confirmations or look in your online banking history under "Transfers" or "Activity."
What if my bank merged with another bank?
Your account number typically stays the same after a merger, though your routing number may change. Log into your online portal or call the new bank to confirm both numbers, especially if you have automatic payments or direct deposits set up.
Do I need both the routing number and account number to receive a refund?
Yes. Most refunds that go directly to your bank account require both numbers. The routing number tells the system which bank to send the money to, and the account number tells it which specific account within that bank. You'll usually enter them together on a form.
