Your bank account number is printed on the bottom left of your checks, shown in your online banking portal, and available by calling your bank

The fastest way is to look at a check from your account. The account number appears on the bottom of the check, after the routing number and before the check number. If you do not have checks, log into your bank's website or mobile app — your account number is usually displayed on the dashboard or in an account details section. If you cannot access online banking, call your bank's customer service line and provide your name and identification; they will read it to you.

Your account number is typically 8 to 12 digits long, though the length varies by bank. It identifies your specific account within that bank's system. You need this number when setting up direct deposit, making wire transfers, paying bills by bank account, or authorizing automatic payments.

Key Takeaways

  • Your account number appears on the bottom left of any check you have, printed between the routing number and the check number.
  • Online banking portals and mobile apps display your account number on the account overview or details page.
  • Calling your bank's customer service line will get you the number within minutes if you cannot locate it another way.
  • Account numbers are typically 8 to 12 digits and are unique to your account at that specific bank.
  • You will need your account number for direct deposit setup, wire transfers, bill payments, and automatic payment authorizations.

Finding it on a physical check

If you have a checkbook, open it and look at any check. At the bottom of the check, you will see three groups of numbers separated by vertical lines. The first group is your routing number. The second group, in the middle, is your account number. The third group on the right is the individual check number.

The account number on a check is always printed in the same position. It will be 8 to 12 digits depending on your bank. Write it down exactly as it appears — do not add spaces or dashes unless your bank's documentation shows them that way.

Checking your online banking account

Log into your bank's website or open the mobile app. On the main dashboard or home screen, your account number is usually visible next to your account name or balance. If it is not when ready visible, look for a link labeled "Account Details," "Account Information," or "Account Settings."

Some banks hide the full account number for security and show only the last four digits on the main screen. If you see only partial numbers, click into the account details section — the full number will be there. You may need to verify your identity with a password or security question before the bank displays the complete number.

Calling your bank directly

If you do not have checks and cannot access online banking, call the customer service number on the back of your debit card or on your bank's website. Have your name, date of birth, and a form of identification ready. The representative will verify your identity and then read your account number to you.

This process usually takes fewer than five minutes. Write down the number as the representative says it and ask them to repeat it so you can confirm it is correct. Some banks also offer automated phone systems where you can log in with your PIN and retrieve the number without speaking to a person.

Finding it in bank statements and documents

Your account number appears on every bank statement you receive, whether by mail or email. Look at the top of the statement near your name and address — the account number is printed there. It is also listed on any official bank documents you have received, such as account opening paperwork or tax forms.

If you have old statements in a file or email, you can pull the account number from any of them. The number does not change unless you close the account and open a new one, so a statement from years ago will still show your current account number.

What to do if you cannot locate it

If you have tried checks, online banking, and statements and still cannot find the number, contact your bank in person at a branch. Bring a photo ID and ask a teller to provide your account number. This is the most direct method and takes only a few minutes.

Do not share your account number with anyone who contacts you unsolicited by phone or email. Legitimate businesses and government agencies will not ask you to confirm your account number this way. If someone calls claiming to be from your bank and asks for this information, hang up and call your bank directly using the number on your card or statement.

Frequently Asked Questions

Is my account number the same as my routing number?

No. Your routing number identifies which bank you use; your account number identifies your specific account within that bank. Both appear on the bottom of a check, but in different positions. You need both numbers for wire transfers and direct deposit setup.

Can I use my account number to send money to someone?

Your account number alone is not enough to send money. You need both your account number and your bank's routing number. Some payment systems also require your bank's name. Always confirm you have the correct information before authorizing a transfer.

What if my account number is different on my check than in my online banking?

This is unusual and suggests an error. Contact your bank when ready to verify which number is correct. Do not use either number until you have confirmed with the bank which one is active for your account.

Do I need to memorize my account number?

You do not need to memorize it, but it is useful to write it down and keep it in a safe place separate from your checks and cards. You will need it periodically for direct deposit, bill payments, and other transactions, so having it readily available saves time.
