Your account number is printed on the bottom left of your checks, visible in your online banking portal, and available by calling your bank
The fastest way is to look at a check from your account. The account number appears on the bottom of the check, usually after the routing number and before the check number. If you do not have checks, log into your bank's website or mobile app — your account number is displayed on the account overview page or in account settings. If you cannot access online banking, call your bank's customer service line (the number is on your debit card or bank statements) and provide your name and identifying information; they will read it to you.
Your account number is unique to that specific account at that specific bank. It is different from your routing number, which identifies the bank itself. You will need both numbers together for wire transfers, direct deposit setup, and automatic bill payments.
Key Takeaways
- Your account number appears on the bottom left of any check you have from that account, printed between the routing number and the check number.
- Online banking shows your account number on the account overview or settings page, usually labeled "Account Number" or "Account Details."
- Calling your bank's customer service line will get you the number within minutes if you cannot locate it any other way.
- Your account number is specific to one account; if you have multiple accounts at the same bank, each has its own number.
- You need both your routing number and account number together for direct deposit, wire transfers, and bill payments.
Reading the account number from a check
The bottom of a check contains three sets of numbers in a specific order. On the far left is the routing number (nine digits), which identifies your bank. In the middle is your account number (usually 10 to 12 digits, though this varies by bank). On the far right is the check number. The account number is the longer middle section.
Not all checks display the account number in the same position or format. Some banks print it in a slightly different order or use different spacing. If you are unsure which number is which, compare it to your online banking portal — the account number you see there should match the middle section on your check.
If your checks are old or the printing is faded, the numbers may be hard to read. In that case, move to your online banking or call your bank instead of trying to decipher worn ink.
Finding it in your online banking account
Log into your bank's website or app and look for your account overview or dashboard. Most banks display your account number prominently on this page, often labeled "Account Number," "Account Details," or "Account Information." Some banks require you to click into account settings or a specific account to see the full number.
If your bank's interface is unfamiliar, look for a menu option like "Accounts," "My Accounts," or "Account Summary." The account number is usually one of the first pieces of information shown. If you still cannot find it, your bank's help section or FAQ will tell you exactly where to look in their specific interface.
Calling your bank to get the number
The customer service number is printed on the back of your debit card, on your bank statements, or on your bank's website. When you call, have your name, date of birth, and the last four digits of your Social Security number or another form of ID ready. The bank will verify your identity before giving you any account information.
Customer service representatives can read your account number to you over the phone, and some can also email or text it to you if you request it. The call usually takes less than five minutes. If you are calling during business hours, wait times are typically short; calling early in the morning or mid-week often means shorter hold times than calling on Friday afternoons.
What to do if you cannot locate your account number
If you have no checks, cannot access online banking, and do not have your debit card, you can still reach your bank through other channels. Visit a branch in person with a photo ID and ask for your account number. The teller can provide it immediately. You can also look at old bank statements if you have them — many statements print the account number at the top or in the account summary section.
If you have recently opened the account and have not received statements yet, online banking is usually active within one business day of account opening. If your online access is not working, call the bank's new account line or customer service to reset your password or troubleshoot login issues.
Account numbers for different account types
If you have multiple accounts at the same bank — a checking account, a savings account, a money market account — each one has its own unique account number. The routing number stays the same (it identifies the bank), but the account number changes for each account. When you set up direct deposit or a bill payment, make sure you are using the account number for the specific account where you want the money to go.
Some banks also issue separate account numbers for joint accounts or accounts held in trust. If you are unsure which account number belongs to which account, your online banking portal will label each one clearly, or you can ask your bank to confirm.
Keeping your account number secure
Your account number is not as sensitive as your PIN or password, but you should still treat it with care. It is safe to share your account number and routing number with your employer (for direct deposit), your utility company (for bill payments), or other trusted organizations that need it to deposit or withdraw money. However, do not share it with people you do not know or on unsecured websites.
If you suspect someone has your account number and may misuse it, contact your bank immediately. They can monitor the account for unauthorized activity and issue you a new account number if necessary, though this process takes time and requires updating all your direct deposits and automatic payments.
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 identify your account; the card number is what merchants use when you swipe or tap the card. You need the account number for direct deposit and wire transfers, not the card number.
Can I use my account number to make purchases online?
No. Online purchases require your debit card number, expiration date, and CVV code. Your account number is for bank-to-bank transfers and direct deposits, not for retail transactions. If a website asks for your account number to process a purchase, it is likely a scam.
What if the account number on my check does not match what I see online?
This is rare but can happen if your checks were printed before you changed accounts or if there was an error during printing. Trust the number shown in your online banking portal, as that is what your bank's system uses. If you are setting up direct deposit or a wire transfer, use the number from your online account, not the check.
How many digits should my account number have?
Most account numbers are between 8 and 17 digits, depending on the bank. There is no standard length across all banks. Your specific bank's account numbers will always be the same length, so if you see a number that looks too short or too long, double-check that you are reading the correct section of the check or account page.
Do I need both my routing number and account number for everything?
For direct deposit, wire transfers, and ACH payments, you need both. For some other transactions, you may only need the account number. When in doubt, provide both — it does not hurt to include the routing number even if only one is strictly required.
