Your bank account number is on your checks, in your online banking portal, and by phone with your bank
The fastest way is to look at a check from your account. The account number appears at the bottom, usually in the middle section between the routing number on the left and the check number on the right. If you do not have checks, log into your bank's website or mobile app — your account number is listed on the account overview or dashboard page, sometimes labeled "Account Number" or "Account Details". If you cannot access online banking, call your bank's customer service line (the number is on your debit card or bank statements) and give them your name and identifying information; they will read it to you.
You need your account number when you set up direct deposit, arrange wire transfers, pay bills through your bank's bill pay system, or provide banking details to an employer or government agency. The account number alone is not enough to access your account — someone would also need your routing number and usually your PIN or online password — but you should still treat it as sensitive information and not share it casually.
Key Takeaways
- Your account number appears at the bottom of any check you have from that account, in the middle section after the routing number.
- If you do not have checks, log into your bank's website or app and look for "Account Details" or "Account Information" on your account overview page.
- You can call your bank's customer service number (printed on your debit card or statement) and ask them to provide your account number over the phone.
- Your account number is needed for direct deposit, bill payments, and wire transfers, but should not be shared with people you do not trust.
Finding your account number online
Most banks display your account number prominently when you log into their website or mobile app. After you sign in, look for a page labeled "Accounts", "Account Overview", "Dashboard", or "My Accounts". Your account number usually appears near the top of that page, often next to your account type (like "Checking" or "Savings") and your current balance.
Some banks hide the full account number for security and show only the last four digits by default. If you see something like "Checking ••••5678", click on that section or look for a "Show" or "Reveal" button to display the complete number. You may need to enter your PIN or answer a security question to reveal it.
If you cannot find it on the main account page, check under "Account Details", "Account Information", or "Settings". Some banks put it in a different location depending on which product you use — for example, a savings account might show it in a different menu than a checking account.
Reading your account number from a check
The bottom of a check contains three sets of numbers separated by vertical lines. From left to right, these are: the routing number (nine digits), the account number (usually 10 to 12 digits), and the check number (three to four digits). Your account number is the middle section.
The numbers are printed in a special magnetic ink that banks can read automatically. You can read them by eye, but the ink and font matter for the bank's processing machines, not for you. Write down the account number exactly as it appears — do not skip digits or rearrange them.
If your checks are very old or damaged, the numbers may be hard to read. In that case, use your online banking portal or call your bank instead.
Getting your account number by phone
Call the customer service number on the back of your debit card, on a recent bank statement, or on your bank's website. Tell the representative you need your account number. They will ask you to verify your identity — usually your full name, date of birth, and the last four digits of your Social Security number or a PIN you set up with the bank.
Once you are verified, they will read your account number to you. Write it down carefully as they say it, or ask them to repeat it. Some banks will also email or text it to you if you ask, though this depends on their security policy.
Customer service lines are usually available during business hours, Monday through Friday, and sometimes on weekends. If your bank is closed, you can still use online banking or check your statements.
Account numbers for different account types
If you have multiple accounts at the same bank — for example, a checking account and a savings account — each one has its own account number. The routing number stays the same across all your accounts at that bank, but the account number changes for each account.
When you set up direct deposit or bill pay, make sure you are using the account number for the specific account you want the money to go into. Using the wrong account number will send the payment to the wrong place, and it can take several days to correct.
If you have accounts at different banks, each bank has its own routing number and each account has its own account number. You cannot mix them — a Wells Fargo account number will not work with a Bank of America routing number.
What to do if you cannot find your account number
If your online banking is not working, you do not have checks, and you cannot reach customer service by phone, check any recent bank statements you have received in the mail. The account number is printed on statements, usually near the top or in a section labeled "Account Information".
If you have a debit card from the account, the account number is not printed on the card itself, but the customer service number on the back will connect you to someone who can provide it. If you have a savings account passbook (older accounts sometimes still use these), the account number is written in the book.
As a last resort, visit a branch of your bank in person with a photo ID. A teller can look up your account and provide the number when ready.
Keeping your account number find
Your account number is not a secret on its own — it appears on checks you send to people, on statements you receive, and on forms you fill out. However, it should not be shared with people you do not know or trust. Someone with your account number and routing number can set up unauthorized transfers or bill payments if they also have access to your online banking credentials.
Do not post your account number on social media, in emails, or in text messages. When you provide it to a business or government agency, make sure you are dealing with the real organization — scammers sometimes pose as banks or employers to collect account numbers.
If you think your account number has been compromised, contact your bank when ready. They can monitor your account for suspicious activity and issue you a new account number if needed, though this usually takes a few days.
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 account; the card number is what merchants use when you swipe or tap the card. You can have the same account number for years, but your debit card number changes each time you get a new card.
Can someone take money from my account if they only have my account number?
Not easily. They would also need your routing number and usually your online banking password or PIN. However, with all three pieces of information, they could potentially set up unauthorized transfers. This is why you should not share your account number with strangers, even though it is not a complete secret.
What if the account number on my check does not match what my bank shows online?
This is rare, but it can happen if you have very old checks or if your account was recently merged or transferred. Call your bank to confirm which number is current. Use the number your bank confirms, not the one on old checks.
Do I need my account number to use my debit card at a store?
No. You only need the card number, which is printed on the front of the card. Your account number is used for direct deposit, bill payments, wire transfers, and other banking transactions, not for everyday card purchases.
Can I change my account number?
Most banks do not allow you to change your account number yourself. If you are concerned about security, contact your bank and ask if they can issue you a new account number. This is usually free but takes several days, and you will need to update any direct deposits or automatic payments that use the old number.
