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

The fastest 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 routing number. The last group, usually nine to twelve digits, is your account number.

If you do not have checks handy, log into your bank's website or mobile app. Most banks display your account number on the dashboard or in an account details section — often labeled "Account Information" or "My Accounts". You may need to click on the specific account to see the full number.

Your monthly bank statement also lists your account number, either at the top of the page or in a section labeled "Account Details". Paper statements show it clearly; digital statements (PDF or online) have it in the same place.

Key Takeaways

  • Your account number appears at the bottom of any check you have written, in the last group of digits after the routing number.
  • Your bank's website or mobile app shows your account number in the account details or dashboard section.
  • Your monthly statement — paper or digital — lists your account number near the top or in an account information section.
  • If you cannot find it yourself, call your bank's customer service line; the number is on your debit card or bank statements.
  • Never share your full account number by email, text, or phone unless you initiated the contact and verified you are speaking to your actual bank.

Finding it through your bank's customer service

If you have lost access to your checks and cannot log into online banking, call the customer service number on the back of your debit card or on a recent bank statement. Have your Social Security number and a form of ID ready. The representative will verify your identity and read your account number to you over the phone.

Some banks also allow you to text a code word to a specific number or use their mobile app to request account details without speaking to anyone. Check your bank's website for these options — they are usually listed under "Contact Us" or "Customer Service".

What to do if you need it urgently

If you need your account number to set up a direct deposit or wire transfer and cannot wait for mail, use your online banking portal or mobile app — both show the number instantly. If your bank's website is down, call the customer service number on your debit card or a recent statement.

Do not rely on memory or old documents. Account numbers can change if you close and reopen an account, and using an outdated number will cause the transaction to fail or route to the wrong place.

Protecting your account number

Your account number is sensitive information. Do not share it in emails, text messages, or over the phone unless you initiated the contact and can confirm you are speaking to your actual bank. Scammers sometimes call claiming to be from your bank and ask for account details.

If someone calls you asking for your account number, hang up and call your bank directly using the number on your debit card or statement. Your bank will never ask you to confirm your full account number over the phone if they called you first.

Different account types and where to find the number

Checking and savings accounts both have account numbers, and they are usually different even at the same bank. If you have multiple accounts, each one has its own number. Your checks will only show the number for your checking account.

Money market accounts, certificates of deposit (CDs), and other account types also have their own numbers. Log into your online banking portal and select each account to see its specific number. If you are setting up a transfer between your own accounts, make sure you are using the correct number for the destination account.

When you have changed banks

If you recently switched banks, your old account number is no longer active. Do not use it for new transactions. Log into your new bank's portal or check a new check to find your current account number.

If you need to reference an old account for a past transaction or tax record, contact your previous bank. They can look up the old account by your name and Social Security number, even if the account is closed.

Frequently Asked Questions

Is my account number the same as my debit card number?

No. Your debit card number is different from your account number. The card number is printed on the front of your card and is used for purchases and ATM withdrawals. Your account number is used for direct deposits, wire transfers, and bank-to-bank transactions. You can find your account number on your checks or in online banking.

Can someone access my account if they know my account number?

Your account number alone is not enough to withdraw money or make unauthorized transfers. Banks also require your routing number, your identity verification, or your PIN. However, treat your account number as sensitive information and do not share it unnecessarily. If you believe someone has misused your account number, contact your bank immediately.

What if my bank statement shows a different account number than my checks?

This is unusual but can happen if your account was recently transferred or restructured. Contact your bank to confirm which number is current. Use the number shown on your most recent statement or in your online banking portal for new transactions.

Do I need my account number to open a savings account at the same bank?

No. When you open a new account, the bank will assign you a new account number. You do not need your existing account number to open another account at the same institution, though you may need to provide your Social Security number and ID.
