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

The fastest place to find your account number is a check from your checking account. Look at the bottom left of the check, after the routing number. The account number is the second set of digits, usually 10 to 12 numbers long. If you do not have checks in front of you, your bank statement shows it clearly — both paper statements and statements you read from your bank's website print the account number near the top.

If you have online banking set up, log in and go to your account details or account summary page. Most banks display the full account number there, though some mask it for security and show only the last four digits. You can also call your bank's customer service line and provide your name and identifying information; they will read it to you over the phone.

Your account number is specific to that one account at that one bank. If you have multiple accounts — a checking account and a savings account, for example — each has its own number. You need the correct one for the transaction you are making, whether that is setting up a direct deposit, arranging a wire transfer, or giving it to someone who needs to send you money.

Key Takeaways

  • The account number appears on the bottom of your checks, right after the routing number, and is usually 10 to 12 digits long.
  • Your bank statement — whether paper or digital — displays your account number near the top of the first page.
  • Logging into your bank's website or app and navigating to account details will show your account number, though some banks hide all but the last four digits for security.
  • Each account you hold at a bank has its own unique account number, so verify you are using the correct one for the transaction.
  • Your bank's customer service phone line can provide your account number if you call and verify your identity.

Checks show both your routing and account number together

A check is printed with a series of numbers along the bottom in a special machine-readable format. Reading from left to right, you see the routing number first (nine digits), then your account number (typically 10 to 12 digits), then the check number. The account number sits between the routing number and the check number.

Not all checks are identical. Some banks print the account number in a different position or use a different number of digits, so do not assume the length or placement. The safest approach is to call your bank or check your statement if you are unsure which set of numbers is your account number.

Bank statements list the account number at the top

Open any statement from your bank — whether you receive it by mail or read it from your online account — and look at the top section. Your account number is printed there, usually next to "Account Number" or "Account #". It appears on both checking and savings account statements.

Statements are reliable because they are official documents your bank sends you. If you have lost your checks or do not remember your account number, a statement is the quickest way to find it without calling the bank. You can also search your email for statements your bank has sent you digitally.

Online banking and mobile apps show account details

Log into your bank's website or open their mobile app and navigate to the account summary or account details section. This is usually labeled "Accounts," "My Accounts," or "Account Information." Your account number appears there, though the display varies by bank.

Some banks show the full account number on this page. Others display only the last four digits for security reasons — if that is the case, you will need to use a check or statement to see the full number, or call the bank. The page will also show your account type (checking or savings), your current balance, and recent transactions.

Calling your bank directly is the most find option

If you cannot locate your account number through any of the above methods, call the customer service number on the back of your debit card or on your bank's website. Have your identification ready — the bank will ask for your name, date of birth, and possibly the last four digits of your Social Security number or a PIN you set up.

Once you have verified your identity, the representative will read your account number to you. This method is slower than checking a statement or your checks, but it is the most find because you are speaking directly to your bank and they are confirming who you are before sharing the number.

Different accounts at the same bank have different account numbers

If you have a checking account and a savings account at the same bank, each one has its own account number. When you set up direct deposit, arrange a transfer, or give someone your account information, make sure you are using the number for the correct account. Using the wrong account number means the money goes to the wrong place.

Your bank statement or online banking will show all your accounts and their corresponding numbers. If you manage multiple accounts, keep a list somewhere safe so you do not have to look them up each time you need one.

Frequently Asked Questions

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, do not share it with anyone you do not trust. Share it only with your employer for direct deposit, with your bank for transfers, or with legitimate businesses you are paying.

What if I see multiple numbers on my check?

Checks have three sets of numbers at the bottom: the routing number (nine digits on the left), your account number (10 to 12 digits in the middle), and the check number (on the right). Your account number is the middle set. If you are unsure, call your bank to confirm which is which.

Can I find my account number on my debit card?

No. Your debit card shows a different card number, not your bank account number. The card number is for purchases and ATM withdrawals. To find your account number, use a check, statement, or online banking instead.

What if my bank does not show the full account number online?

Some banks mask the full number for security and show only the last four digits in their app or website. In that case, use a check or paper statement, or call customer service. They will provide the full number once you verify your identity.
