Your account number is printed on the bottom left of your checks, in your bank's online portal, and on statements mailed to you
The easiest place to find your checking account number is the bottom left corner of any check you have. It appears after the routing number and before the check number itself. If you do not have checks in front of you, log into your bank's website or mobile app — your account number will appear on the account overview or dashboard page. You can also call your bank's customer service line and provide your name and identifying information; they will read it to you.
Your account number is unique to that specific checking account at that specific bank. If you have multiple accounts at the same bank, each one has its own number. The number typically runs 8 to 12 digits, though the length varies by bank.

Reading the MICR line on a check
The bottom of every check contains a line of numbers printed in a special machine-readable format called the MICR line (Magnetic Ink Character Recognition). This line always follows the same order: routing number, account number, check number.
The routing number comes first and is nine digits. Your account number follows when ready after. It is not separated by a space or dash on the check itself, so you need to count carefully. Once you pass the nine-digit routing number, the next sequence of digits (usually 8 to 12 of them) is your account number. The final short sequence on the right is the check number.
If the numbers are hard to read because the check is old or worn, request a new checkbook from your bank. A fresh set of checks will have clear, legible numbers.
Finding it in your online banking portal
Log into your bank's website or mobile app using your username and password. Look for a section labeled "Accounts," "Account Details," "Account Information," or "Dashboard." Your checking account number will be displayed prominently on this page, usually near the account name and balance.
Some banks show the full account number; others show it partially masked for security (for example, the last four digits only). If your bank displays a masked number and you need the full number, look for a "Show" or "Reveal" button, or click on the account name itself to expand the details. If neither option appears, you can call customer service to request the full number.
The online portal is often the fastest way to find your number if you are away from home or do not have checks available.
Checking your bank statements
Paper statements mailed to your address will show your account number on the first page, usually in the top right or top left corner near your name and address. It may also appear in the account summary section. If you receive electronic statements instead, open the PDF and look in the same locations.
Statements are typically mailed monthly, so this method works only if you have a recent one on hand. If your last statement is more than a few months old, the information is still accurate — your account number does not change unless you close the account and open a new one.
Calling your bank directly
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 the last four digits of your Social Security number ready. The representative will verify your identity and read your account number to you over the phone.
This method takes a few minutes but requires no login or paperwork. It is useful if you need the number when ready and cannot access your checks or online account. Customer service lines are usually available during business hours and sometimes 24/7, depending on your bank.
What your account number is used for
Your account number, combined with your routing number, tells the banking system exactly where your money should go. When you set up direct deposit for a paycheck, transfer money between banks, or receive a wire transfer, you provide both numbers so the funds reach the correct account.
Your account number alone is not enough to access your account or move money — a thief would also need your routing number, and typically your online banking password or other verification. However, treat your full account number as you would any financial information: do not share it with people you do not trust, and do not post it on social media or unsecured websites.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is printed on the front of the card and is different from your account number. Your account number is what the banking system uses to identify your checking account; your card number is what merchants and ATMs use to process transactions. You can have the same account number for years, but your debit card number changes each time you get a new card.
Can I find my account number on my debit card?
No, your debit card does not display your account number. The card shows only the card number, expiration date, and cardholder name. To find your account number, use your checks, online banking, statements, or call your bank.
What if I have multiple checking accounts at the same bank?
Each account has its own unique account number. When you log into online banking, you will see all your accounts listed separately, each with its own number. If you have checks for each account, the account number on each checkbook will be different.
Do I need both my routing number and account number to receive a transfer?
Yes. Both numbers are required for direct deposits, wire transfers, and ACH transfers. The routing number tells the system which bank to send the money to; the account number tells it which account at that bank. Without both, the transfer cannot be completed.
