Your account number appears on checks, bank statements, and online banking
Your account number is a unique identifier for your specific bank account. It is different from your routing number, which identifies your bank itself. You can find your account number in several places without calling your bank or visiting a branch.
The fastest method depends on what you have access to right now. If you have a physical check, look at the bottom. If you have online banking set up, log in and check your account details page. If you have a recent statement, the account number appears near the top.
Key Takeaways
- Your account number is printed on the bottom of every check you write, after the routing number and before the check number.
- Online banking shows your account number on the account details or summary page, usually labeled "Account Number" or "Account ID".
- Bank statements mailed to your home display the account number near the top, often next to your name.
- If you cannot find your account number through these methods, contact your bank directly by phone or in person with your ID.
Finding your account number on a check
Look at the bottom of any check from your checkbook. You will see a series of numbers printed in magnetic ink. Reading from left to right, the first set of numbers is your routing number (usually nine digits), the second set is your account number (typically 10 to 12 digits), and the third set is the check number.
The account number is the middle group. It may have leading zeros, and those zeros matter — write down or type the full number exactly as it appears. If you do not have checks or your checks are old, move to another method.
Checking your online banking portal
Log into your bank's website or mobile app using your username and password. Once you are logged in, look for a section labeled "Account Details," "Account Information," "Account Summary," or "My Accounts." The account number is usually displayed prominently on this page.
Some banks show the account number in full; others mask it with asterisks for security and only show the last four digits. If your bank masks the number, you may need to click a button or link that says "Show Full Account Number" or "Unmask." You will typically need to verify your identity or enter a security code to see the full number.
Looking at your bank statement
Open a recent bank statement, whether printed or digital. The account number is usually printed near the top of the page, often just below or next to your name and address. It may be labeled "Account Number," "Account #," or "Acct #."
Statements sent by mail typically show the full account number in plain text. Statements you download from online banking may mask the number for security. If you receive statements by email, the PDF or attachment will show the account number the same way your online portal does.
Contacting your bank if you cannot locate it
If you do not have checks, cannot access online banking, and do not have a recent statement, call your bank's customer service line. The number is on the back of your debit card or on your bank's website. Have your ID ready and be prepared to answer security questions to verify your identity.
You can also visit a branch in person with a photo ID. A teller can print your account number for you or write it down while you wait. This method takes longer but requires no passwords or online access.
Understanding account number format and length
Account numbers vary by bank and account type. Most are between 8 and 17 digits long. Some banks use letters and numbers together, though this is less common. The format does not matter for your purposes — what matters is that you have the exact number your bank uses for your account.
Leading zeros are significant. If your account number is 0012345678, do not write it as 12345678. When you provide the number to someone else — a payroll department, a creditor, or a government agency — include every digit exactly as your bank shows it.
Keeping your account number secure
Your account number, combined with your routing number, allows someone to set up automatic transfers from your account. Do not share your full account number with people you do not trust. If you are providing it to a business or government agency, confirm first that they are legitimate and that they have a secure way to receive it.
When you write checks, your account number is visible to anyone who handles the check. This is normal and expected. If you are concerned about sharing your account number online, use a phone call or in-person visit instead, or ask the organization if they have a secure portal for submitting banking information.
Frequently Asked Questions
Is my account number the same as my account ID?
Usually yes. Banks often use the terms interchangeably. Your account ID is the number your bank uses to identify your account internally. If your bank distinguishes between the two, the account number is what you need for transfers and payments.
Can I find my account number on my debit card?
No. Your debit card shows your card number (the 16-digit number on the front), which is different from your account number. The card number is tied to your account but is not the same thing. Use a check, statement, or online banking to find your account number.
What if my account number has changed?
Account numbers do not change unless you close the account and open a new one. If you think your number has changed, contact your bank. You may have opened a second account, or there may be confusion between your account number and another identifier.
Do I need both my routing number and account number?
Yes, for most transfers and automatic payments. Your routing number tells the system which bank to use; your account number tells it which account within that bank. Both are printed on your checks in order: routing number first, then account number.
