Your account number is on your checks, your bank statement, and in your online banking login

Your bank account number is a string of digits that identifies your specific account at your bank. It is different from your routing number — the routing number identifies the bank itself, while your account number identifies you within that bank. You can find your account number in at least three places without calling the bank or visiting a branch.

The easiest place to look is a check from your checking account. Open your checkbook and look at the bottom left of any check. You will see three groups of numbers separated by colons or special symbols. The middle group is your account number. It is usually 10 to 12 digits long, though the length varies by bank.

If you do not have checks or prefer not to use them, your bank statement shows your account number at the top. Whether you receive paper statements in the mail or view them online through your bank's website, the account number appears near your name and address. Online statements are often easier to search — you can use your browser's find function to locate it quickly.

Key Takeaways

  • Your account number appears on the bottom of any check you have, in the middle group of numbers between the routing number and the check number.
  • Bank statements, whether paper or online, display your account number near the top with your personal information.
  • Your online banking portal shows your account number when you log in, usually on the account summary or dashboard page.
  • Your account number is safe to share with people who need to send you money, such as employers setting up direct deposit or creditors arranging payments.

Finding it in your online banking account

Log into your bank's website or mobile app using your username and password. Once you are logged in, look for a page labeled "Account Summary," "My Accounts," or "Dashboard." Your account number is usually displayed prominently on this page, often next to your account type (such as "Checking" or "Savings").

Some banks hide the full account number for security reasons and show only the last four digits on the main page. If you see only partial numbers, look for a link that says "View Full Account Number" or "Account Details." Clicking this will reveal the complete number. You may need to answer a security question or enter a PIN before the bank shows you the full number.

What your account number tells you

Your account number is unique to you at that specific bank. If you have multiple accounts at the same bank — a checking account and a savings account, for example — each one has its own account number. The account number does not change unless you close the account and open a new one.

The account number itself does not reveal sensitive information like your balance or transaction history. It is safe to write it down, share it with your employer for direct deposit, or give it to someone who needs to send you a wire transfer or ACH payment. However, you should never share your account number along with your routing number and PIN, as that combination could allow someone to access your account.

Why you might need it

You will need your account number when setting up direct deposit for your paycheck, arranging automatic bill payments, or receiving a wire transfer from someone outside your bank. If you are moving money between your own accounts at different banks, you will need both your account number and routing number for the receiving bank.

Some employers ask for your account number before your first paycheck so they can deposit your wages directly into your account. Utility companies, insurance companies, and loan servicers may also ask for it if you want to pay your bill automatically each month. In each case, having your account number ready speeds up the process.

Keeping track of multiple account numbers

If you have accounts at more than one bank, write down each account number and the bank name in a safe place — a notebook you keep at home, a password manager, or a find document on your computer. Do not store account numbers in your phone's notes app or email, as these can be accessed if your phone or email is compromised.

A straightforward table works well: bank name in one column, account type in another, and account number in a third. Update it whenever you open a new account or close an old one. This way, when you need the number for direct deposit or a payment arrangement, you can find it without logging into your bank or searching for a statement.

What to do if you cannot find your account number

If you have lost your checks, cannot access your online banking, and do not have a recent statement, you can contact your bank directly. Call the customer service number on the back of your debit card, or visit a branch in person with your ID. The bank will provide your account number over the phone or in person.

You can also request a new statement from your bank if you need one. Many banks allow you to request statements through their website or app, and they will email or mail it to you. This usually takes a few business days, so if you need the number right away, a phone call to customer service is faster.

Frequently Asked Questions

Is it safe to give my account number to someone?

Your account number alone is safe to share with employers, creditors, and people sending you money. However, never share it together with your routing number and PIN, as that combination could allow unauthorized access. If someone asks for all three pieces of information at once, verify they are legitimate before providing anything.

What is the difference between my account number and my routing number?

Your routing number identifies your bank — all customers at the same bank branch share the same routing number. Your account number identifies your specific account within that bank. You need both when receiving direct deposits or wire transfers, but they serve different purposes.

Can I change my account number?

You cannot change your account number while keeping the same account open. If you need a new account number, you would have to close your current account and open a new one, which is usually not necessary. Contact your bank if you are concerned about your account number's security.

Do I need my account number to use my debit card?

No. Your debit card has its own number printed on the front, which is different from your account number. You use the card number for purchases and online transactions. Your account number is only needed for direct deposits, wire transfers, and automatic bill payments.

What if I have a joint account?

A joint account has one account number shared by both account holders. Either person can use that account number to set up direct deposit or payments. Both people have equal access to the account and the same account number.
