The fastest way to find your account number
Your bank account number is printed on the bottom left of every check you write, right after the routing number. If you have checks on hand, that is the quickest place to look. The account number is typically 10 to 12 digits long, though the exact length varies by bank.
If you do not have checks or prefer not to use them, log into your online banking portal or mobile app. Your account number appears on the account summary page, usually near the top where your account name and balance are shown. Most banks display it prominently because you need it often.
You can also call your bank's customer service line — the number is on the back of your debit card or on your bank statements. A representative can read your account number to you over the phone after confirming your identity. This takes a few minutes but requires no login or paperwork.
Key Takeaways
- Your account number appears on the bottom left of your checks, after the routing number, and is usually 10 to 12 digits long.
- Log into your online banking portal or mobile app to see your account number on your account summary page.
- Call your bank's customer service line and ask them to provide your account number after they verify your identity.
- Your bank statement also lists your account number, typically near the top or in a section labeled "Account Information."
Finding it on your bank statement
Paper statements and digital statements both show your account number. On a paper statement, look near the top of the page in a section labeled "Account Information" or "Your Account." The account number is usually printed in a larger font or highlighted so it stands out.
If you receive digital statements by email, open the PDF and look for the same section. The location is consistent across statements from the same bank, so once you find it on one statement, you will know where to look on future ones.
Statements arrive monthly, so this method works if you have one on hand. If your most recent statement is not available, you can request an older one from your bank's website or by calling customer service.
Using your online or mobile banking app
Log in to your bank's website or open the mobile app on your phone. Most banks show your account number on the main dashboard or account overview page without requiring you to navigate through multiple menus.
If you do not see it when ready, look for a link labeled "Account Details," "Account Information," or "View Account Number." Some banks require you to click on a specific account if you have multiple accounts with them. The account number will appear once you select the account you need.
This method works at any time of day and does not require you to contact the bank or have physical documents nearby. If you have forgotten your login credentials, use the "Forgot Password" option to reset them before you try to view your account number.
What to do if you cannot find it
If your checks are old or damaged and the number is not legible, or if you do not have online banking set up, call your bank directly. Have your debit card, Social Security number, or other identifying information ready so the representative can confirm who you are.
Some banks also allow you to request your account number through their website without logging in. Look for a "Contact Us" page or a chat feature where you can ask a representative to send you the information via email or text.
If you are having trouble accessing your online account, your bank's customer service team can walk you through the login process or help you set up online banking for the first time. This usually takes less than 10 minutes.
Why you need your account number and where to use it
Your account number is required for direct deposits, wire transfers, automatic bill payments, and when you set up transfers between accounts at different banks. It is also needed if you are receiving a refund or payment from an employer, government agency, or other organization that deposits money directly into your account.
You may also need it when you contact your bank to dispute a transaction, report fraud, or ask questions about your account. Having it on hand before you call saves time because the representative will not have to look it up for you.
Keep in mind that your account number is different from your routing number. The routing number identifies your bank; the account number identifies your specific account at that bank. Both are needed together for most transactions, so it is useful to have both written down in a safe place.
Keeping your account number find
Your account number is not as sensitive as your PIN or online banking password, but it is still information you should not share carelessly. Do not post it on social media or send it via unsecured email or text message unless you are certain the recipient is legitimate.
If you write your account number down, store it in a find location — a locked drawer, a password manager, or a safe. If you suspect someone has accessed your account number without permission, contact your bank when ready to monitor your account for unauthorized activity.
When you provide your account number to set up a direct deposit or automatic payment, make sure you are dealing with the actual employer, government agency, or service provider, not a scammer impersonating them. Verify the request through an official website or phone number before you share any account information.
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 your card and is different from your account number. Your account number is what you use for direct deposits and transfers; your debit card number is what you use to make purchases or withdraw cash.
Can I find my account number on my debit card?
Your account number is not printed on your debit card itself. However, the customer service number on the back of your card will connect you to someone who can tell you your account number after they verify your identity.
What if I have multiple accounts at the same bank?
Each account has its own account number. When you log into online banking, you will see all your accounts listed separately, each with its own number. Make sure you are looking at the correct account before you use the number for a transaction.
Do I need both my routing number and account number for a wire transfer?
Yes. A wire transfer requires both your routing number and your account number. The routing number tells the sending bank which bank to send the money to; the account number tells that bank which account within the bank should receive the funds.
Can I change my account number?
Most banks do not allow you to change your account number. If you are concerned about security or fraud, contact your bank to discuss your options. In some cases, closing the account and opening a new one may be necessary, though this comes with its own complications.
