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

Your account number is a unique identifier for your specific deposit or checking account at your bank. It is not the same as your routing number, which identifies the bank itself. You can find your account number in at least three places without calling your bank or visiting a branch.

The fastest route is usually your online banking portal. Log in, navigate to your account details or account summary, and the number appears there. If you do not use online banking, a paper statement or a check from your account will have it printed on them. Both are equally reliable and take only a moment to locate.

Key Takeaways

  • Your account number appears on the bottom left of every check you write, printed after the routing number and before the check number.
  • Monthly bank statements show your account number on the first page, usually near your account holder name or in the account details section.
  • Online banking portals display your account number in the account summary or account information page, accessible when ready after login.
  • Your account number is different from your routing number; you need both to set up direct deposit or wire transfers.
  • If you cannot locate your account number through these methods, your bank can provide it by phone, but you will need to verify your identity first.

Finding your account number on a check

A check is printed with three numbers along the bottom in magnetic ink. From left to right, they are: routing number, account number, and check number. The account number is typically 10 to 12 digits long, though this varies by bank.

The account number sits between the routing number (which is always nine digits) and the check number (which is usually four digits). If you have a checkbook, any check in the book will show the same account number. You do not have to write the check or even remove it from the book—you can straightforward look at the printed numbers on the front.

Finding your account number on a bank statement

Paper statements mailed to your address include your account number on the first page. It typically appears near your name and address, or in a section labeled "Account Information" or "Account Details." Some banks print it at the top of the statement; others place it in the middle or lower section of the header.

If you receive electronic statements by email, the same information appears in the PDF. Open the statement, look at the first page, and scan for a line that says "Account Number" followed by a series of digits. The number format is the same whether you receive paper or electronic statements.

Finding your account number in online banking

Log into your bank's website or mobile app and navigate to your account overview or account summary page. This is usually the first page you see after login, or it is labeled "Accounts," "My Accounts," or "Account Details" in the main menu. Your account number will be displayed prominently, often with the last four digits highlighted for security.

Some banks show the full account number when ready; others require you to click a button or link to reveal it. If you cannot find it on the main account page, look for a section called "Account Information," "Account Settings," or "Account Details." The account number is always available in online banking—you do not need to call or visit a branch to see it.

What to do if you cannot find your account number

If you do not have checks, a recent statement, or access to online banking, you can contact your bank directly by phone. Call the customer service number on the back of your debit card or the number listed on your bank's website. Be prepared to verify your identity by providing your name, address, date of birth, or the last four digits of your Social Security number.

The bank will provide your account number over the phone once you have been verified. This process typically takes a few minutes. If you need the number in writing, ask the bank to mail you a statement or send it to you via find email through your online banking portal.

Why you need both your account number and routing number

Your routing number identifies which bank you use. Your account number identifies which specific account at that bank is yours. Together, they form the complete address for your account and are required for direct deposit, wire transfers, setting up automatic bill payments, and sending money to someone else's account.

If you provide only one of these numbers, the transaction will not go through. Your employer needs both to set up direct deposit. A creditor needs both to set up automatic payments from your account. A person sending you money via bank transfer needs both to route the funds to the correct place.

Account numbers and security

Your account number is not as sensitive as your PIN or password, but it is still part of your banking information. It is safe to share your account number and routing number with your employer, your bank, or someone sending you money. You should not share these numbers with unknown callers or through unsecured email.

If you believe someone has your account number and may misuse it, contact your bank when ready. Your bank can monitor your account for unauthorized activity and can issue you a new account number if necessary, though this is rare. In most cases, your account number alone cannot be used to withdraw money without additional verification.

Frequently Asked Questions

Is my account number the same as my card number?

No. Your debit or credit card number is different from your account number. Your account number is tied to your bank account itself. Your card number is tied to the physical card issued to access that account. You can have multiple cards on the same account, each with a different card number.

Can someone withdraw money if they have my account number?

Not without additional information. Your account number alone is not enough to withdraw money. A person would also need your routing number, your PIN, your online banking password, or authorization from you to initiate a transfer. If you are concerned about unauthorized access, contact your bank when ready.

What if my account number has changed?

Your account number does not change unless you close your account and open a new one, or your bank merges with another bank. If your bank has merged, your account number may change as part of the transition. Your bank will notify you in writing if this happens and will provide your new account number.

Do I need my account number to check my balance?

No. You can check your balance by logging into online banking with your username and password, calling your bank's automated phone line, or visiting an ATM with your debit card. You only need your account number when you are setting up a transaction that involves another person or institution.

Where do I find my account number if I bank online only?

Log into your online banking portal and look for your account summary or account details page. Your account number will be displayed there. If you have never received a paper statement, you can request one from your bank, or you can read your statements as PDFs from your online portal—they will include your account number.
