Your bank account number is printed on the bottom left of your checks, shown in your online banking portal, or available by calling your bank's customer service line.

The fastest way is to look at a check from your account. The account number appears after the routing number on the bottom of the check, printed in magnetic ink. If you do not have checks, log into your bank's website or mobile app — most banks display your account number prominently on the dashboard or in an account details section. If neither of those works, call the phone number on the back of your debit card and ask for your account number; the bank can verify you by asking security questions.

You need this number when you set up direct deposit, arrange wire transfers, or give payment details to employers or creditors. Banks sometimes use different account numbers for different account types (checking, savings, money market), so make sure you have the right one for what you are doing.

Key Takeaways

  • Your account number is printed on the bottom left of any check you have, after the routing number.
  • Online banking portals and mobile apps show your account number in the account details or dashboard section.
  • You can call your bank's customer service line and provide security information to get your account number by phone.
  • Different account types at the same bank may have different account numbers, so confirm you have the right one for your purpose.
  • You will need your account number for direct deposit, wire transfers, bill payments, and other transactions that move money between accounts.

Finding your account number on a check

A check has three numbers printed in magnetic ink along the bottom. From left to right, they are the routing number, your account number, and the check number. Your account number is the middle one and is usually 10 to 12 digits long, though the length varies by bank.

The account number on a check is the same for all checks from that account. If you have old checks from years ago, the account number will still be correct — banks do not change account numbers when you renew your checkbook. If you have multiple accounts at the same bank (a checking account and a savings account, for example), each one will have its own account number, and each will appear on checks or statements for that specific account.

Checking your online banking portal or app

Log into your bank's website or open the mobile app and look for a section labeled "Account Details," "Account Information," or "My Accounts." Most banks display your account number on the main dashboard as soon as you log in, or you may need to click on the specific account to see its details.

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 page — the full account number will appear there. You may also see it on your monthly statement, usually near the top or in a section labeled "Account Information."

Calling your bank to get your account number

Call the customer service number on the back of your debit card or on your most recent bank statement. Tell the representative you need your account number. They will ask you security questions to verify your identity — typically your Social Security number, date of birth, and the answer to a security question you set up when you opened the account.

This method works even if you do not have checks or online access. The call usually takes fewer than five minutes. Write down the account number the representative gives you, and ask them to confirm it by reading it back to you — account numbers are long and straightforward to mishear.

Understanding account numbers for different account types

If you have both a checking account and a savings account at the same bank, each account has its own account number. The routing number stays the same, but the account number changes. This matters because if you set up direct deposit to the wrong account number, your paycheck will go to your savings account instead of checking, or vice versa.

Before you give your account number to an employer, creditor, or service provider, confirm which account you want the money to go into. If you are unsure, ask the bank which account number corresponds to which account type — they can tell you in seconds.

What to do if you cannot find your account number

If you have no checks, cannot access online banking, and do not have your debit card, visit a branch in person with a photo ID. A teller can look up your account number when ready. Bring any mail from the bank — statements, debit card offers, or account notices — because these often contain your account number.

If you have forgotten your online banking password, use the "Forgot Password" link on the bank's website to reset it. You will usually need to verify your identity by answering security questions or confirming a code sent to your phone or email. Once you reset your password, you can log in and find your account number.

Frequently Asked Questions

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

No. Your debit card number is printed on the front of the card and is different from your account number. The account number appears on checks and in your online banking portal. Some transactions use the debit card number, while others use the account number and routing number.

Can I change my account number if I want to?

Banks do not routinely change account numbers. If you are concerned about fraud or security, contact your bank directly — they can discuss your options, which may include closing the account and opening a new one with a different number.

Do I need both the routing number and account number?

Yes, for most transfers and direct deposits. The routing number tells the banking system which bank to send the money to, and the account number tells it which specific account within that bank. Both are required for the money to reach the right place.

What if someone has my account number?

An account number alone is not enough to withdraw money or make unauthorized transfers — the person would also need your routing number, PIN, or online banking password. If you are concerned, contact your bank and ask them to monitor the account for suspicious activity.

Will my account number change if I move to a different branch?

No. Your account number stays the same no matter which branch you visit or which state you move to. The routing number may change if you move to a different bank, but your account number at your current bank remains constant.
