Your checking account number is printed on the bottom left of your checks, or you can find it in your bank's app or online portal
The account number is a unique identifier your bank assigns to your checking account. It is different from your routing number (which identifies the bank itself) and different from your card number. You need it to set up direct deposit, arrange wire transfers, authorize automatic bill payments, and receive refunds from the IRS or state tax agencies.
The fastest way to find it depends on what you have access to right now. If you have a check, it takes five seconds. If you do not, your bank's website or mobile app will show it in under a minute. If you cannot access either, a phone call to your bank's customer service line gets you the answer in a few minutes.
Key Takeaways
- Your account number appears on the bottom left of any check you have, printed between the routing number and the check number.
- You can view your account number in your bank's mobile app or online banking portal without needing a check or calling anyone.
- If you do not have checks or online access, call your bank's customer service number on the back of your debit card or on their website.
- Never share your account number with anyone except your employer (for direct deposit), the IRS, or your bank itself.
- The account number is typically 8 to 12 digits long, but the exact length varies by bank.
Reading the account number from a check
Open any check from your account. Look at the bottom of the check. You will see three groups of numbers printed in a special magnetic ink format.
The first group is your routing number (nine digits). The second group, in the middle, is your account number (usually 8 to 12 digits, depending on your bank). The third group on the right is the check number.
Write down the account number from the second group. That is the number you need for direct deposit, wire transfers, and refund routing.
Finding your account number online or in your bank's app
Log into your bank's website or open their mobile app. Look for a section labeled "Account Details," "Account Information," or "My Accounts."
Your account number will be displayed there, usually near your account type (Checking, Savings, etc.) and your current balance. Some banks show the full number; others mask it with asterisks and show only the last four digits. If you see only the last four digits, you can usually click to reveal the full number, or you can call customer service to confirm the complete account number.
This method works even if you have never ordered checks or if your checks are at home and you need the number right now.
Calling your bank to get your account number
If you do not have a check and cannot access online banking, call your bank's customer service line. The phone number is usually on the back of your debit card or on your bank's website.
Tell the representative you need your checking account number. They will ask you to verify your identity—usually by providing your name, date of birth, and the last four digits of your Social Security number or your debit card number. Once verified, they will read your full account number to you.
Write it down as they say it, and ask them to repeat it so you can confirm you have it correct. This call typically takes fewer than five minutes.
What your account number looks like and how long it is
Account numbers are not standardized across all banks. Most are between 8 and 12 digits long, but some banks use longer or shorter numbers. They contain only numbers—no letters or special characters.
When you see your account number in your bank's app or online portal, it may be formatted with spaces or dashes for readability (for example, 123-456-789), but when you enter it into a form or provide it over the phone, you typically type or say only the digits with no spaces.
If you are unsure whether you have copied the number correctly, compare it to the version shown in your bank's app or on a check. They should match exactly.
Using your account number for refunds and direct deposit
When you set up direct deposit for a paycheck or tax refund, you will be asked for your account number along with your routing number. The IRS, your employer, and your state tax agency all use this pair of numbers to deposit money into the correct account.
For tax refunds specifically, the IRS uses your account number to route your refund to your bank. If you provide an incorrect account number, the refund may go to the wrong account or be rejected by your bank. If this happens, the IRS will mail you a check instead, which takes several weeks longer.
Double-check your account number before submitting any refund or direct deposit form. Verify it against your check or your bank's app.
Keeping your account number secure
Your account number is sensitive information. Share it only with people and organizations you trust: your employer (for payroll), the IRS or your state tax agency (for refunds), your bank, and any business you have authorized to withdraw money from your account (like a utility company or insurance provider).
Do not share your account number in response to unsolicited emails, texts, or phone calls. Legitimate banks and government agencies will never ask you to confirm your account number via email or text. If someone contacts you claiming to be from your bank or the IRS and asks for your account number, hang up or delete the message and call your bank directly using the number on your debit 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 your card and is used for purchases and ATM withdrawals. Your account number is different and is used for direct deposit, wire transfers, and bill payments. You can have the same account number for years, but your debit card number changes each time you get a new card.
What if I cannot find my account number anywhere?
Call your bank's customer service line. You can find the number on the back of your debit card, on your bank statement, or on the bank's website. Have your ID ready so you can verify your identity. The representative will provide your account number over the phone.
Can I use my account number to make purchases online?
No. Your account number is not a payment method. To pay online, use your debit card number, credit card number, or a service like PayPal or Apple Pay. Your account number is only for direct deposits, transfers between accounts, and bill payments you have authorized.
Will my account number change if I switch banks?
Yes. Each bank assigns its own account numbers. If you move your checking account to a new bank, you will receive a new account number. You will need to update your direct deposit information with your employer and any organizations that withdraw money from your account automatically.
What should I do if I think someone has my account number?
Contact your bank immediately. Tell them you believe your account number may have been compromised. They can monitor your account for unauthorized activity and may issue you a new account number if necessary. Review your recent transactions to make sure no unauthorized withdrawals have occurred.
