Your account number is printed on the bottom left of your checks, in your online banking portal, and on statements your bank mails you
The easiest place to look is the bottom of a check from your checking account. The account number appears after the routing number — it is the second set of digits on that line. If you do not have checks, log into your bank's website or mobile app and look for "Account Details" or "Account Information." Your account number will be listed there. If you cannot access online banking, call your bank's customer service number on the back of your debit card or on a recent statement.
Your bank statement — whether you get it by mail or email — also shows your account number near the top. Some banks print it on your debit card itself, though not all do. If you have a savings account, money market account, or any other account type at the same bank, each one has its own separate account number.
Key Takeaways
- Your account number appears on the bottom left of checks, right after the routing number.
- You can find it in your online banking portal under Account Details or Account Information.
- Bank statements — mailed or emailed — display your account number near the top of the page.
- Each account you hold at the same bank has a different account number, even if they are both checking accounts.
- If you cannot locate it yourself, call the customer service number on your debit card or a recent statement.
Finding it on a check
Look at the bottom of any check. You will see a series of numbers printed in a special magnetic ink. The first set of numbers on the left is your routing number. The second set, which comes right after it, is your account number. The account number is usually 10 to 12 digits long, though the exact length varies by bank.
If your checks are old or faded, the numbers may be hard to read. In that case, move to your online banking portal or call your bank instead. Do not guess at the digits — using the wrong account number means your payment or transfer will go to the wrong place.
Finding it in online banking
Log into your bank's website or open the mobile app. Look for a section labeled "Accounts," "Account Details," "Account Information," or "My Accounts." Click on the specific account you need the number for — if you have multiple accounts, each one will be listed separately.
Your account number will be displayed prominently on that page. Some banks also let you copy it to your clipboard with a single click, which is useful if you need to paste it into a form. If you cannot find the account information section, use the search function within the app or website and type "account number."
Finding it on a bank statement
Open a recent bank statement, whether it arrived by mail or email. The account number is usually printed near the top of the page, often next to the account type (like "Checking" or "Savings"). It may also appear in a box labeled "Account Information" or "Your Account Details."
If you receive statements by email, search your email inbox for "statement" and open the most recent one. If you receive paper statements but cannot find a recent one, you can request a duplicate from your bank — most banks will email or mail one to you at no cost.
Finding it on your debit card
Some banks print the account number on the debit card itself, usually on the front or back. However, not all banks do this for security reasons. If your card does not show it, use one of the other methods above instead.
Never share your account number with anyone unless you initiated the contact and trust the person or organization. Legitimate businesses will never ask you to confirm your account number by email or text.
What to do if you cannot find it
Call your bank's customer service number. You can find this number on the back of your debit card, on a recent statement, or on your bank's website. Have your identification ready — the bank will ask you to verify who you are before sharing your account number.
You can also visit a branch in person with your ID. A teller can write down your account number for you or print a statement that shows it. If you are new to banking or have been away from your account for a while, the staff can walk you through how to access your account number online so you can find it yourself next time.
Why you need your account number
Your account number is required when you set up direct deposit for paychecks, arrange automatic bill payments, or transfer money between banks. It is also needed if someone outside your bank needs to send you money — for example, a tax refund or a payment from an employer.
Your account number is different from your routing number. The routing number identifies which bank you use; the account number identifies which specific account at that bank is yours. You often need both together to complete a transaction.
Frequently Asked Questions
Is it safe to give my account number to someone?
Your account number alone cannot be used to withdraw money from your account — a thief would also need your routing number and your signature or authorization. However, only share it with people and organizations you trust and who have a legitimate reason to need it, such as your employer or a company you are paying.
What if I have multiple accounts at the same bank?
Each account has its own separate account number. When you log into online banking, you will see all your accounts listed. Click on the specific account to view its account number. Make sure you are using the correct number for the account you want to use.
Can I change my account number?
No, your account number is permanent and tied to that specific account. If you want a fresh start, you would need to close the old account and open a new one, which would give you a new account number. However, this is rarely necessary and can disrupt automatic payments and direct deposits.
Do I need my account number to use my debit card?
No. Your debit card has its own number printed on the front, which is different from your account number. You use the card number for purchases and online shopping. You only need your account number for bank transfers, direct deposit, and bill payments.
What if my account number is printed wrong on my checks?
Contact your bank when ready. A wrong account number on checks means deposits or payments could go to the wrong account. Your bank can reorder checks with the correct number at no cost, or you can use online banking and bill pay instead while you wait for new checks to arrive.
