Your bank account number is printed on the bottom left of your checks, in your online banking portal, or on a statement from your bank

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. It is usually 8 to 12 digits long, though the length varies by bank.

If you do not have checks, log into your bank's website or mobile app. Your account number appears on the account overview page, often labeled "Account Number" or "Account Details". Some banks show it on the dashboard when ready after you sign in; others require you to click into a specific account.

A paper statement mailed by your bank also displays the account number at the top or in a summary section. If you have an old statement, the number is there. Your bank can also tell you the number over the phone if you call customer service and verify your identity.

Key Takeaways

  • Your account number appears on the bottom left of any check you have, printed between the routing number and the check number.
  • Online banking portals and mobile apps show your account number on the account overview or details page, usually without logging into a separate section.
  • Paper statements display the account number in the header or summary area, and old statements work just as well as current ones.
  • Your bank's customer service line can provide the number over the phone after you verify your identity with personal information.

Finding it in online banking

Log into your bank's website using your username and password. Most banks display your account number on the main dashboard or the first page you see after signing in. Look for a section labeled "Accounts", "Account Summary", or "My Accounts".

If the number is not visible on the main page, click into the specific account you need. Banks often hide the full account number behind a "Show" or "View Details" button for security. Click that button and the full number appears. Some banks show only the last four digits by default.

Mobile apps follow the same pattern. Open the app, sign in, and navigate to the account overview. The account number is usually visible without additional clicks, though some apps require you to tap an account card to expand the details.

Reading it from a check

Open a check from your checking account and look at the bottom of the check. You will see a series of numbers printed in a special magnetic ink format. These numbers read from left to right as: routing number, account number, check number.

The routing number is nine digits. The account number comes when ready after and is typically 8 to 12 digits long. The check number is the shortest sequence, usually 3 to 4 digits, and appears on the right side of the bottom line and also in the top right corner of the check.

If you are unsure which sequence is which, the routing number always comes first. Your bank's routing number is the same for all your accounts at that bank. The account number is unique to that specific account.

Getting it from a bank statement

Your account number appears on every statement your bank sends you, whether by mail or email. On a paper statement, look at the top of the first page. The account number is usually printed in the header section, near your name and address.

Some banks print it as "Account Number:" followed by the digits. Others list it in a summary box that includes your account type and current balance. If you cannot find it in the header, scan the first page for a section labeled "Account Information" or "Account Details".

PDF statements sent by email follow the same layout. Open the statement and look at the top of the document. The account number is in the same location as it would be on a printed statement.

Calling your bank directly

If you cannot locate the number through any of these methods, call your bank's customer service line. The number is on the back of your debit card, on your bank's website, or in a statement you have received.

When you call, be prepared to verify your identity. The bank will ask for information such as your full name, date of birth, the last four digits of your Social Security number, or answers to security questions you set up when you opened the account. After verification, a representative will provide your account number.

Some banks also allow you to retrieve your account number through their automated phone system without speaking to a representative. Follow the prompts to sign in with your account credentials, and the system will read your account number to you.

Account numbers for different account types

Each account you hold at a bank has its own unique account number. If you have a checking account and a savings account at the same bank, they have different account numbers even though they share the same routing number.

When you need to provide an account number, make sure you are giving the number for the correct account. If you are setting up a direct deposit to your checking account, use the checking account number, not the savings account number. Using the wrong number will send the deposit to the wrong account.

Your online banking portal lists all your accounts separately, so you can see each account number at a glance. If you have multiple banks, each bank has a different routing number and each account has its own account number.

Why you need it and where it goes

Your account number is required whenever money needs to move into or out of your specific account. Direct deposits from an employer, automatic bill payments, wire transfers, and ACH transfers all require your account number along with your routing number.

You will provide this number to your employer's payroll department, to creditors or service providers setting up automatic payments, and to anyone sending you money via bank transfer. The account number tells the banking system which account at which bank should receive or send the funds.

Keep your account number reasonably private, though it is less sensitive than your PIN or online banking password. Your account number alone cannot be used to withdraw money or change your account settings. However, combined with your routing number, it can be used to set up transfers, so do not share it with people you do not trust.

Frequently Asked Questions

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

No. Your debit card number is a 16-digit number printed on the front of your card. Your account number is typically 8 to 12 digits and is found on checks, statements, or in online banking. They are different numbers tied to the same account.

Can someone withdraw money if they have my account number?

Not with the account number alone. A person would need both your account number and your routing number to set up a transfer, and even then, many banks require additional verification. Your PIN and online banking password are more sensitive because they allow direct access to your account.

What if I cannot find my account number anywhere?

Call your bank's customer service line. You will need to verify your identity with personal information like your name, date of birth, or Social Security number. The representative will provide your account number when ready.

Do I need a different account number for wire transfers versus ACH transfers?

No. The same account number works for all types of transfers into or out of that account. The routing number may differ depending on the type of transfer, but the account number remains the same.

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

Log into your online banking portal and navigate to your account overview or details page. Most online-only banks display the account number prominently on the dashboard. If not, look for a "View Details" or "Account Information" button to expand the full number.
