Your account number is printed on the bottom left of every check you write
The easiest place to find your checking account number is on a check from your account. Look at the bottom of the check, on the left side. You will see a series of numbers — usually between 10 and 12 digits. That is your account number. It stays the same for as long as you keep that account open.
If you do not have checks handy or have not ordered them yet, your bank can tell you your account number in seconds. You do not need to go to a branch — a phone call or login to your online account will get you the number when ready.
Key Takeaways
- Your account number appears on the bottom left of any check from your account, printed as a series of 10 to 12 digits.
- You can find your account number by logging into your online banking account or mobile app without leaving home.
- Calling your bank's customer service line and providing your name and identifying information will give you your account number over the phone.
- Your bank statement — whether paper or digital — lists your account number at the top or in the account summary section.
- Never share your account number with anyone unless you are setting up a direct deposit, automatic payment, or wire transfer with a trusted organization.
Check your online banking account or mobile app
Log into your bank's website or open their mobile app using your username and password. Your account number is usually displayed on the main dashboard or account summary page — often right next to your account balance. Some banks show it prominently; others require you to click on "Account Details" or "Account Information" to see it.
This method works even if you are away from home or do not have physical checks. The number you see online is the same one printed on your checks, so you can use it when ready for direct deposits, bill payments, or other transactions.
Look at your bank statement
Whether you receive a paper statement in the mail or view it online, your account number is listed somewhere on that document. Paper statements typically show it at the top of the page or in a box labeled "Account Information." Digital statements usually display it in the same location or in a downloadable PDF version.
If you have not received a recent statement, you can usually request one through your online account or by calling your bank. Many banks also let you view past statements going back several months or years through their website.
Call your bank's customer service number
The phone number for customer service is on the back of your debit card, on your bank statements, or on your bank's website. When you call, a representative will ask you to verify your identity — usually by providing your name, date of birth, and the last four digits of your Social Security number or another piece of identifying information.
Once verified, they will give you your full account number over the phone. This is a standard request and takes only a minute or two. If you are uncomfortable sharing information over the phone, you can ask the representative to mail the information to the address on file instead.
Visit your bank branch in person
Walk into any branch of your bank with a photo ID. Tell a teller or banker that you need your account number. They will look it up in their system and provide it to you when ready. This method works even if you have never visited that particular branch before — all branches can access your account information.
This is often the slowest option because it requires you to travel during business hours, but it is useful if you prefer face-to-face interaction or if you are already at the bank for another reason.
What to do if you cannot remember which bank you use
If you have a debit card, the bank name is printed on the front. If you have old checks or statements, the bank name and usually a branch address appear on them. You can also search your email for messages from your bank — most banks send account confirmations, statements, or promotional emails that include the bank name.
If you truly cannot locate any records, you can search for banks in your area online or call your local Chamber of Commerce. Once you identify the bank, use any of the methods above to retrieve your account number.
Why you might need your account number
Your account number is required for setting up direct deposits from an employer or government program, arranging automatic bill payments, receiving wire transfers, or sending money to another person's account. Some employers and service providers ask for both your account number and your routing number together — the routing number identifies which bank you use, while the account number identifies your specific account within that bank.
Keep your account number private and share it only with organizations you trust. Legitimate businesses — your employer, your utility company, your bank — will never ask you to confirm your account number by email or text. If someone contacts you asking for it unsolicited, do not provide it.
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 your card and is different from your account number. Your account number is what you use for direct deposits and bank transfers. Your debit card number is what you use to make purchases or withdraw cash.
Can I use my account number to make purchases online?
No. Online purchases require your debit card number, expiration date, and security code. Your account number is only for bank-to-bank transactions like direct deposits and bill payments. Never enter your account number into a retail website.
What if I have multiple accounts at the same bank?
Each account has its own unique account number. When you log into your online banking, you will see all your accounts listed separately, each with its own number. Make sure you are looking at the correct account before using the number.
Do I need my account number to open a new account at the same bank?
No. When opening a new account, the bank will create a new account number for you. You do not need to provide your existing account number unless you are transferring money between your own accounts at that bank.
What should I do if I think someone has my account number?
Contact your bank when ready by phone using the number on the back of your debit card or on your statement. Tell them you believe your account number may have been compromised. They can monitor your account for unusual activity and may issue you a new account number if necessary.
