The fastest way: look at your checks or debit card

Your checking account number is printed on the bottom left of every check you have. It is the middle set of numbers, after the routing number and before the check number on the far right. If you have your debit card, the account number is usually printed on the front or back — check both sides.

If you have neither checks nor a debit card yet, or if the numbers are worn and unreadable, move to the next section. But if you can read them right now, you have what you need.

Key Takeaways

  • Your account number appears on the bottom of your checks (middle set of numbers) and often on your debit card.
  • Your bank's website or mobile app shows your account number in the account details or settings section, usually without logging in required for the first lookup.
  • Calling your bank's customer service line on the back of your debit card or on their website will get you the number in under five minutes.
  • Your monthly bank statement lists your account number at the top or in the account summary section.
  • If you opened your account online, check your email for the account opening confirmation — it contains your account number.

Log into your bank's website or app

Open your bank's website or mobile app and sign in with your username and password. Once you are logged in, look for a section called "Account Details," "Account Information," or "My Accounts." Your account number will be displayed there, usually near your account type (like "Checking") and your current balance.

If you cannot remember your password, use the "Forgot Password" link on the login page. You will need to verify your identity using your email address or phone number, and the bank will send you a reset link. This usually takes a few minutes.

Call your bank's customer service line

The phone number for customer service is on the back of your debit card, on your monthly statement, or on your bank's website. When you call, have your Social Security number and a form of ID ready — the bank will ask you to verify your identity before sharing account information.

Tell the representative you need your checking account number. They will read it to you over the phone. Write it down or ask them to repeat it. This call usually takes fewer than five minutes, and you do not need to be logged into anything online.

Check your monthly bank statement

Your account number appears on every monthly statement your bank sends you. Look at the top of the first page or in a section labeled "Account Summary" or "Account Information." The number will be listed next to your account type.

If you receive statements by mail, look through recent ones. If you receive statements by email, search your email inbox for "statement" or "bank statement" and open a recent one. The account number format is the same whether the statement is on paper or digital.

Look for your account opening confirmation email

When you opened your checking account, your bank sent you a confirmation email. This email contains your account number, routing number, and other account details. Search your email inbox for messages from your bank with words like "welcome," "account opened," or "confirmation."

If you cannot find the email in your inbox, check your spam or promotions folder — sometimes banks' emails end up there by mistake. The email may be several months or years old if you opened the account a while ago, so search by the bank's name rather than by date.

Visit your bank in person

Walk into any branch of your bank with a photo ID. Tell a teller or banker that you need your checking account number. They will look it up in their system and give it to you. You do not need an appointment, and this takes just a few minutes.

This option works even if you have lost your debit card, forgotten your password, or do not have access to your statements. Bring your ID and be ready to answer a security question or two to confirm your identity.

Frequently Asked Questions

Is my account number the same as my routing number?

No. Your routing number identifies your bank; your account number identifies your specific account at that bank. On a check, the routing number comes first (on the left), and the account number comes second (in the middle). You need both for wire transfers and direct deposits.

Can I share my account number with anyone?

You can share it with people or businesses you trust to deposit money into your account or set up automatic payments. Do not share it with strangers or in response to unsolicited calls or emails. Legitimate businesses you already work with (your employer, your landlord) will ask for it directly.

What if I cannot remember my bank's name?

Look at your debit card — the bank name is printed on the front. If you do not have the card, check your email for recent statements or account messages. You can also search your email for "bank" or "statement" to find messages from your financial institution.

Do I need my account number to open a savings account at the same bank?

No. You can open a savings account with just your ID and Social Security number. The bank will assign you a new account number for the savings account. Your checking and savings accounts are separate, each with its own number.
