Check your checks or debit card first

Your account number appears on the bottom left of every check you write. Look at the string of numbers on the bottom of the check — the first set is your routing number, and the second set (usually 10 to 12 digits) is your account number. If you have checks from your account, this is the fastest place to look.

Your debit card does not print your account number on the front, but your bank can confirm it by the card number if you call. Some banks show the account number on statements or receipts from ATM withdrawals, though this varies by bank. The card number itself — the 16 digits printed on the front — is separate from your account number and is used only for purchases and cash withdrawals.

Log into your online banking portal

Most banks display your account number prominently on the dashboard or home page when you sign in. Look for a section labeled "Account Details," "Account Information," or "My Accounts" — your full account number will be listed there alongside your account type (checking, savings, money market).

If you cannot find it on the main page, check your account statements. Banks usually include the account number at the top of each monthly statement, whether you receive it by mail or download it as a PDF from your online account. The statement will also show your routing number, which you may need for the same transaction.

Call your bank's customer service line

The phone number is on the back of your debit card, on your statements, or on your bank's website. When you call, have your Social Security number, date of birth, and the last four digits of your debit card ready. The representative will verify your identity and read your account number to you over the phone.

This method takes longer than checking a check or logging in online, but it works if you have lost your checks and cannot access your online account. Some banks also allow you to request this information through their mobile app or by sending a secure message through your online portal. Wait times vary by bank and time of day, so calling during off-peak hours (early morning or late afternoon on weekdays) may be faster.

Visit a branch in person

Bring a photo ID and ask a teller for your account number. They will look it up in their system and provide it to you immediately. This is useful if you need to verify the number on the spot or if you have questions about which account number to use (for example, if you have multiple accounts at the same bank).

Branches are typically open Monday through Friday during business hours, and many have Saturday hours. Some banks also offer extended hours or Sunday service at select locations. If you are unsure of your branch location or hours, search your bank's name plus "branch locator" on their website.

Key Takeaways

  • Your account number appears on the bottom left of any check from your account, after the routing number, and is usually 10 to 12 digits long.
  • Logging into your bank's website or mobile app will show your account number on the dashboard or in your account details section, often alongside your routing number.
  • Calling your bank's customer service line requires identity verification but works if you do not have checks or online access.
  • Visiting a branch in person with a photo ID is the fastest way to confirm your account number if you need it immediately and have questions about multiple accounts.
  • Your debit card number and your account number are different — the card number is for purchases, while the account number is for direct deposit and bank transfers.

What to do if you have multiple accounts

If you have more than one account at the same bank — for example, a checking account and a savings account — make sure you are using the correct account number for what you need. Checks are drawn only from checking accounts, so if you have both types, your check will show only your checking account number. Your savings account will have a separate account number.

When you set up direct deposit, wire transfers, or automatic payments, the bank will ask you to specify which account the money should go to. Providing the wrong account number will send the money to the wrong place, so double-check before submitting. If you are unsure which number belongs to which account, ask the teller or customer service representative to confirm both the account number and the account type (checking or savings) at the same time.

Frequently Asked Questions

Is my account number the same as my routing number?

No. Your routing number identifies your bank or credit union (usually nine digits), while your account number identifies your specific account at that bank (usually 10 to 12 digits). Both appear on the bottom of your checks, with the routing number first.

Can I find my account number on my debit card?

Your debit card shows a card number, which is different from your account number. The card number is for purchases and ATM withdrawals. Your account number is not printed on the card itself, but your bank can tell you the account number if you call with your card number and verify your identity.

What if I do not have checks or online access?

Call your bank's customer service line with your Social Security number and date of birth ready, or visit a branch with a photo ID. Both methods will get you your account number without needing checks or a working online login.

Do I need my account number to use my debit card?

No. You use your card number (the 16 digits on the front of the card) for purchases and ATM withdrawals. You need your account number only for direct deposit, wire transfers, automatic bill payments, or when you are dealing directly with your bank.

How long does it take to get my account number over the phone?

Once you reach a representative and verify your identity, they can provide your account number within a few minutes. Total wait time depends on how busy the bank's phone line is, which varies by time of day and day of week.
