Your account number is on your checks, your bank statement, and your online banking login
Your bank account number is a string of digits that identifies your specific account at your bank. It is not the same as your routing number (which identifies the bank itself). You can find your account number in at least three places right now without calling anyone or waiting for mail.
The fastest place to look is a check from your checkbook. Open the check and look at the bottom left. You will see three groups of numbers separated by colons or special symbols. The middle group is your routing number; the last group is your account number. It is usually 10 to 12 digits long, though the exact length varies by bank.
If you do not have checks handy, log into your online banking. Your account number appears on the account summary or dashboard page — often labeled "Account Number" or "Account Details." Some banks also print it on your debit card statement or in your account settings.
Key Takeaways
- Your account number is printed at the bottom of every check you write, in the last group of numbers after the routing number.
- You can see your account number by logging into your bank's website or mobile app under account details or summary.
- Your bank statement (paper or digital) lists your account number at the top or in the account information section.
- Never share your full account number with anyone who contacts you first — legitimate businesses already have it if they need it.
Finding your account number on a paper statement
If you receive a monthly statement in the mail, your account number is printed near the top of the first page. Look for a line that says "Account Number" or "Acct #" followed by a series of digits. This is the same number that appears on your checks.
The statement also shows your routing number nearby, usually labeled "Routing Number" or "ABA Number." Both numbers together are what you need if you are setting up direct deposit, arranging a wire transfer, or giving payment instructions to an employer or creditor.
Locating it in your online banking portal
Log into your bank's website or open the mobile app. Look for a section called "Accounts," "Account Summary," or "Dashboard." Your account number should appear on the main screen or in a dropdown menu that shows all your accounts.
If you cannot find it on the main page, look for a link labeled "Account Details," "Account Information," or "Settings." Some banks hide the full account number behind a "Show" button for security reasons — you may need to click to reveal it. If you are still stuck, your bank's help section or FAQ usually has a page titled "Where is my account number?" with screenshots.
What to do if you cannot locate it
Call your bank's customer service number on the back of your debit card or on your most recent statement. Have your name, address, and the last four digits of your Social Security number ready. The representative will confirm your identity and read your account number to you over the phone.
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. This is useful if you need it when ready and do not have online access or checks available.
Why you need your account number and when to share it
Your account number is required for direct deposit (when an employer or government agency sends money to your account), wire transfers, setting up automatic bill payments, and receiving payments from other people or organizations. It is a normal piece of information to provide when you are the one requesting a transaction.
Be cautious about sharing your account number unsolicited. If someone calls or emails you claiming to be from your bank and asks for your account number, hang up or delete the message. Your bank already has your account number — they do not need you to provide it. Scammers sometimes pose as banks to collect this information. If you are unsure whether a call is real, hang up and call the number on your bank card or statement instead.
The difference between account number and routing number
Your routing number identifies which bank you use. Your account number identifies which account you have at that bank. Think of the routing number as your bank's address and the account number as your mailbox number at that address.
Both numbers appear together at the bottom of your checks in this order: routing number, then account number. You need both when setting up direct deposit or receiving a wire transfer. When you are sending money out (paying a bill, for example), you usually only need the account number of the person or organization you are paying.
Keeping your account number safe
Your account number is not as sensitive as your PIN or password, but it is still worth protecting. Do not write it on a sticky note or leave it visible on your desk. Store it in a find place — a locked drawer, a password manager, or a note in your phone that is password-protected.
If you suspect someone has your account number and you are worried about fraud, contact your bank when ready. They can monitor your account for suspicious activity and issue you a new account number if necessary, though this process takes time and affects any automatic payments you have set up.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your debit or credit card number is printed on the front of the card and is different from your account number. Your account number is what the bank uses internally to track your account. You can have multiple cards linked to the same account number.
Can someone take money from my account if they have my account number?
Not easily. Your account number alone is not enough to withdraw money or make unauthorized transfers. Most transactions also require your PIN, password, or signature. However, if someone has both your account number and routing number, they could attempt to set up unauthorized automatic payments, so contact your bank if you think your information has been compromised.
What if my bank merged or changed its name?
Your account number usually stays the same even if your bank merges or rebrands. Your routing number may change, so check your most recent statement or online banking to confirm both numbers are current before setting up direct deposit or wire transfers.
Do I need my account number to open a new account at the same bank?
No. When opening a new account, the bank will assign you a new account number. You do not need to provide your old account number unless you are transferring money between your own accounts, in which case you will need both numbers.
