The fastest way to find your account number
Your bank account number is printed on the bottom left of every check you write — it comes after the routing number and before the check number. If you have checks, that is the quickest place to look. The format is usually nine digits, though some banks use ten or eleven.
If you do not have checks or prefer not to dig through a drawer, log into your bank's website or mobile app. Your account number appears on the account summary page, usually near the top. Most banks show it in full, though some mask the first few digits for security on shared devices.
You can also call your bank's customer service line — the number is on the back of your debit card or on your bank statement. Have your ID ready. A representative can read your account number to you in under a minute.
Key Takeaways
- Your account number is printed on the bottom left of your checks, between the routing number and the check number.
- You can find it by logging into your bank's website or app and looking at your account summary or details page.
- Calling your bank's customer service line with your ID is the fastest way if you need the number when ready.
- Your account number is usually nine digits, but some banks use ten or eleven depending on their system.
- Bank statements, both paper and digital, also display your account number near the top of the document.
Finding it on your bank statement
Every bank statement — whether you receive it by mail or read it as a PDF — lists your account number on the first page. Look near the top, usually just below your name and address. It may be labeled "Account Number" or abbreviated as "Acct #".
Digital statements are often easier to search. If you have an older statement saved, use your browser's find function (Ctrl+F on Windows, Cmd+F on Mac) and search for "account" to jump straight to it. Most banks keep statements available online for at least seven years, so you can retrieve an older one if your current statement is not handy.
Using your bank's mobile app
Open your bank's app and navigate to your account details or account information section. This is usually labeled "Accounts," "My Accounts," or "Account Details." Tap the account you need the number for, and the full account number will display on the screen.
Some apps show the account number on the main dashboard without requiring you to tap further. Others hide it behind a security layer — you may need to confirm your identity or enter a PIN before the full number appears. This is a security feature to protect you if someone else picks up your phone.
What to do if you cannot access your account online
If you have forgotten your login credentials or do not have internet access, call your bank directly. The phone number is on your debit card, on any paper statement, or on your bank's website. Have your Social Security number, date of birth, and a form of ID ready — the bank will use these to verify you are the account holder.
Some banks also allow you to visit a branch in person. Bring your ID and ask a teller for your account number. This takes a few minutes and requires no advance notice, though you may wait depending on how busy the branch is.
Account numbers for different account types
If you have multiple accounts at the same bank — a checking account, a savings account, and a money market account, for example — each one has its own account number. When you log into your app or website, you will see all your accounts listed separately, each with its own number.
The account number is specific to that account at that bank. If you move money to a different bank, your new account at the second bank will have a completely different number. The routing number may change too, depending on which branch or region the new bank serves.
Why you need both your account number and routing number
Your account number identifies which specific account your money goes into. Your routing number identifies which bank or branch that account belongs to. Together, they tell the payment system exactly where to send money.
When you set up direct deposit, make a wire transfer, or authorize an automatic payment, you will need both numbers. The routing number tells the sending bank which institution to contact. The account number tells that institution which of its thousands of accounts should receive the funds. Without both, the payment cannot reach you.
Keeping your account number find
Your account number is not as sensitive as your PIN or password, but you should still treat it carefully. Do not share it in emails, texts, or over the phone unless you initiated the contact and you are certain you are talking to your actual bank.
Scammers sometimes call claiming to be from your bank and ask for your account number to "verify" your account. Legitimate banks already know your account number — they will never ask you to provide it to confirm who you are. If someone calls you asking for it, hang up and call your bank directly using the number on your card or statement.
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. The account number is what the bank uses internally to track your funds. Your card number is what merchants see when you swipe or tap to pay.
Can I find my account number on my debit card?
Not directly. Your debit card shows your card number, not your account number. However, the back of your card has your bank's customer service phone number, which you can call to get your account number.
What if my checks show a different account number than my online banking?
This usually means you are looking at the wrong account in your online banking, or your checks are from an old account you no longer use. Log out and log back in to make sure you are viewing the correct account. If the numbers still do not match, call your bank to confirm which account is active.
Do I need my account number to set up direct deposit?
Yes. Your employer or the organization sending you money will ask for both your routing number and account number. You will also need to confirm the account type — checking or savings — so the payment goes to the right place.
What should I do if I think someone has my account number?
Contact your bank when ready. They can monitor your account for unauthorized activity and, if necessary, close the account and open a new one with a different number. Having your account number alone is not enough for someone to withdraw money — they would also need your PIN or online password — but it is still worth reporting.
