Your account number is on your checks, your bank statement, and inside your online banking portal
The easiest place to find your account number is the bottom left of any check you have. It appears 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 will be listed on the account summary or dashboard page, often labeled "Account Number" or "Account Details." You can also call your bank's customer service line and ask them to read it to you.
Your bank statement — whether you receive it by mail or download it as a PDF — also shows your account number at the top or in the account information section. If you have a debit card, the account number may appear on the back or inside your online banking profile, though not always on the card itself.
Key Takeaways
- Your account number appears on the bottom left of your checks, between the routing number and the check number.
- Log into your bank's website or app and look for "Account Number" or "Account Details" on the main account page.
- Bank statements — paper or digital — display your account number in the account information section.
- Call your bank's customer service number on the back of your debit card if you cannot locate it online or on paper.
Finding it on your bank's website or app
Most banks show your account number on the home page or dashboard as soon as you log in. Look for a section labeled "Accounts," "Account Summary," or "My Accounts." Click on the specific account you need — checking, savings, or money market — and the full account number will appear near the top.
If you cannot find it on the main page, look for a link or tab called "Account Details," "Account Information," or "Settings." Some banks hide it one click deeper. The account number is always a string of 8 to 17 digits, depending on your bank.
Mobile apps follow the same pattern. Open the app, tap the account you need, and look for "Account Number" or "Details." If the app does not show the full number for security reasons, the website version usually will.
What to do if you cannot find it online
Call the customer service number on the back of your debit card or on your bank statement. Have your account holder name, date of birth, and the last four digits of your Social Security number ready. The representative will read your full account number to you over the phone.
You can also visit a branch in person with a photo ID and ask a teller to write down your account number. This takes a few minutes and requires no appointment at most banks.
If you have online banking set up but the account number is not visible, your bank may have a security setting that hides it. Call customer service and ask them to enable full account number display in your online portal, or ask them to email or mail it to you.
Why you need it and where it goes
Your account number is required for direct deposit, wire transfers, automatic bill payments, and tax refund delivery. When you set up direct deposit for a paycheck or refund, you will enter your routing number and account number together — they work as a pair to tell the sending bank exactly where your money should land.
You may also need it to authorize ACH transfers (electronic money movement between banks), to set up recurring payments to creditors or service providers, or to receive government payments like tax refunds or stimulus checks. Keep it private the same way you would a PIN — do not share it in emails or texts, and do not write it on documents you leave lying around.
The difference between account number and routing number
Your routing number identifies your bank or credit union — it is the same for all customers at that institution. Your account number identifies your specific account at that bank. Together they form the address where money gets sent.
If you give someone only your routing number, they cannot send you money because they do not know which account at the bank is yours. If you give only your account number, they cannot send money because they do not know which bank to send it to. You always need both.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is a 16-digit number printed on the front of your card. Your account number is separate and usually 8 to 17 digits. You can find your account number on checks, bank statements, or in your online banking portal. Your bank can tell you which number to use for a specific transaction.
Can I use my account number to pay someone in person?
No. Your account number is for electronic transfers and direct deposit only. For in-person payments, use your debit card, a check, or cash. Giving your account number to a store or business is not safe and will not work for payment.
What if I see multiple account numbers listed online?
You may have more than one account at the same bank — a checking account, a savings account, or a money market account, for example. Each one has its own account number. Use the account number that matches the account you want the money to go into. If you are unsure which is which, call your bank.
Do I need my account number to check my balance?
No. You can check your balance by logging into your bank's website or app with your username and password, calling the automated phone line, or visiting a branch. Your account number is only required when you are sending or receiving money electronically.
