Your account number is printed on the bottom left of your checks, in your bank's mobile app, and on statements your bank mails or emails you
The fastest way is to look at a check from your checking 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 in front of you, log into your bank's website or mobile app — your account number is usually visible on the dashboard or in an account details section. You can also call your bank's customer service line, and they will read it to you after confirming your identity.
If you have not received statements yet or cannot access your online account, your bank mailed you a welcome letter when you opened the account. That letter contains your account number. You can also visit a branch in person with your ID, and a teller will provide it when ready.
Key Takeaways
- Your account number appears on the bottom left of checks, right after the routing number and before the check number.
- Logging into your bank's website or app shows your account number on the account overview or details page.
- Your bank's welcome letter, mailed when you opened the account, lists your account number.
- Calling your bank's customer service line and providing identification is the fastest option if you cannot access other sources.
Finding it on a check
Open a checkbook from the account you need. At the bottom of any check, you will see three sets of numbers separated by vertical lines. The first set is the routing number (nine digits). The second set, usually longer, is your account number. The third set is the check number.
Account numbers vary in length by bank — some are eight digits, others are twelve or more. Write down all the digits you see. If the numbers are faint or worn, hold the check under bright light or use your phone's camera to zoom in.
Finding it in your online banking
Log into your bank's website or app using your username and password. Most banks display your account number on the main dashboard or home screen, often next to your account name and balance. If you do not see it there, look for a link labeled "Account Details," "Account Information," or "Manage Accounts." Click it, and your full account number will appear.
Some banks hide the full number for security and show only the last four digits on the main screen. If that happens, click into the specific account or the details section to reveal the complete number. Take a screenshot or write it down so you have it when you need it.
Finding it on statements and welcome letters
Your bank sends you a statement each month — either by mail or email, depending on what you chose when you opened the account. Your account number appears near the top of the statement, usually next to your account name. If you signed up for paperless statements, log into your online banking and read a recent statement as a PDF.
Your welcome letter, sent when you first opened the account, also lists your account number. Check your filing or email inbox for a letter from your bank dated around the time you opened the account. The account number is usually printed in a highlighted box or near the top of the letter.
Calling your bank directly
If you cannot find your account number through any other method, call the customer service number on the back of your debit card or on your bank's website. Have your ID ready — the bank will ask you to confirm your identity by providing your Social Security number, date of birth, or answers to security questions you set up when you opened the account.
Once you are verified, the representative will read your account number to you. Ask them to spell it out digit by digit so you write it correctly. This call usually takes less than five minutes.
Visiting a branch in person
Walk into any branch of your bank with a government-issued ID. Tell a teller you need your account number. They will look it up in seconds and write it down for you or print a small slip with the number on it. This is the most straightforward option if you are already near a branch.
Bring your ID even if the teller knows you — banks require identification for security reasons. If you do not have your ID with you, you can still call ahead and ask the branch to have the information ready when you arrive.
What to do if you have multiple accounts
If you have more than one account at the same bank — a checking account and a savings account, for example — each one has its own account number. When you look at a check, you are seeing the number for that checking account only. Your savings account number is different.
To find the account number for a savings or money market account, log into your online banking and click on that specific account, or call your bank and ask for the number associated with that account by name. Write down each account number separately and label which account it belongs to so you do not mix them up when you need to use them.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank (nine digits). Your account number identifies your specific account at that bank (usually eight to twelve digits). Both appear on the bottom of checks, but in different positions. You need both numbers to set up direct deposit or wire transfers.
Can I use the last four digits of my account number instead of the full number?
No. Banks require the complete account number for transactions like direct deposit, bill pay, or transfers. The last four digits alone are not enough to process a payment or identify your account in their system.
What if I cannot find a check or access my online account?
Call your bank's customer service number or visit a branch in person. Both can provide your account number within minutes. You will need to verify your identity with your Social Security number, date of birth, or other security information.
Is it safe to share my account number?
Your account number alone cannot be used to withdraw money from your account — a thief would also need your routing number and other information. However, only share your account number with people or organizations you trust, such as your employer for direct deposit or your bank for legitimate transactions.
Do I need my account number to use my debit card?
No. Your debit card works at ATMs and stores without your account number. You only need your account number for direct deposit, wire transfers, bill pay, or when setting up automatic payments.
