Your account number is printed on the bottom left of your checks, in your bank's mobile app, and on statements mailed to 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, open your bank's mobile app or log into your online banking portal — your account number is listed in the account details or summary section. You can also call your bank's customer service line and provide your name and Social Security number to confirm it.

Paper statements mailed to your address also show your account number, usually near the top. If you have switched to paperless statements, you can still access old statements through your online account. Some banks print the account number on debit cards, though not all do — check the back or front of your card.

Key Takeaways

  • Your account number appears on the bottom left of checks, right after the routing number.
  • Bank mobile apps and online portals display your account number in the account summary or details section.
  • Mailed bank statements show your account number near the top of the page.
  • Calling your bank's customer service line and verifying your identity will get you the number if you cannot locate it another way.
  • Your account number is specific to one account at one bank — if you have multiple accounts, each has its own number.

Finding it through online banking

Log into your bank's website or app using your username and password. Look for a section labeled "Account Details," "Account Information," "My Accounts," or "Account Summary." Your account number should appear prominently on that page, often alongside your account type (checking, savings, money market) and current balance.

If you cannot find it in the main account view, check the settings or profile section. Some banks hide the full account number behind a "Show" button for security reasons — you may need to click to reveal it. Screenshot or write down the number once you locate it, since you may need it for wire transfers, direct deposit setup, or bill payments.

Locating it on paper checks and statements

Open a check from your checking account and look at the bottom. You will see a series of numbers printed in a special magnetic ink format. The first set of numbers (usually 9 digits) is your routing number. The second set of numbers (usually 10 to 12 digits) is your account number. The third set is the check number itself.

If you have a bank statement in hand, flip to the first page. Your account number is typically printed in the upper right corner or near the account holder's name and address. Monthly statements, quarterly statements, and annual statements all display it in the same location. Older statements you have saved will show the same account number, since it does not change unless you close and reopen the account.

Calling your bank to confirm your account number

Dial the customer service number on the back of your debit card or on your bank's website. Have your name, date of birth, and Social Security number ready. The representative will verify your identity and read your account number aloud to you.

This method is useful if you have lost access to your online account, do not have checks, or have not received a statement recently. It also gives you a chance to ask whether your account number has changed or if there are any holds on the account. Keep a record of the date and time you called in case you need to reference it later.

Understanding what your account number means

Your account number is unique to one specific account at one specific bank. If you have a checking account and a savings account at the same bank, each one has its own account number. If you have accounts at two different banks, the account numbers are completely separate and unrelated.

The account number itself does not reveal your balance, transaction history, or other sensitive information — it is simply an identifier. However, you should treat it like a password and not share it with people you do not trust. Scammers sometimes use account numbers to set up unauthorized transfers or payments, so keep it private unless you are providing it to your bank, your employer, or a business you are paying intentionally.

What to do if you cannot locate your account number

If you have tried checking your checks, statements, and online account and still cannot find it, contact your bank directly. Call the number on your debit card or visit a branch in person with a photo ID. The bank can print out a statement on the spot or write the number down for you.

If you are locked out of your online account, use the "Forgot Password" or "Forgot Username" link on your bank's website to regain access. You will usually need to verify your identity using your email address, phone number, or security questions. Once you are back in, your account number will be visible in the account details section.

Account numbers for different account types

Checking accounts, savings accounts, and money market accounts all have separate account numbers at the same bank. If you are setting up direct deposit for your paycheck, make sure you use the account number for the checking account where you want the money to go, not your savings account number. Using the wrong account number will send the deposit to the wrong place.

If you have a joint account with another person, there is one account number for that account. Both account holders can use the same account number for transfers and payments. If you later split the account or add another person, the bank may issue a new account number for the new account structure.

Frequently Asked Questions

Is my account number the same as my routing number?

No. Your routing number identifies which bank you use, while your account number identifies which specific account at that bank is yours. Both appear on the bottom of checks, but in different positions. You need both numbers to set up direct deposit or wire transfers.

Can someone steal money using just my account number?

It is difficult but not impossible. Someone with your account number and routing number could potentially set up an unauthorized ACH transfer or payment. This is why you should not share your account number with strangers or post it on social media. If you suspect fraud, contact your bank immediately.

What if I have multiple accounts at the same bank?

Each account has its own account number. When you set up direct deposit, bill payments, or transfers, you must specify which account number you want the money to go to. Using the wrong account number will route the money to a different account.

Do I need my account number to call my bank?

No. You can call your bank and verify your identity using your name, date of birth, and Social Security number. The representative will then provide your account number. However, having your account number handy when you call can speed up the process.

Will my account number change if I close and reopen an account?

Yes. When you close an account and open a new one, the bank assigns a new account number. This is why you need to update direct deposit information and automatic payments if you switch accounts. The old account number will no longer work once the account is closed.
