Bank of America checking accounts have 10 digits

Your Bank of America checking account number is 10 digits long. You'll find it on the bottom left of your checks, in your online banking portal, or by calling customer service at 1-800-432-1000.

The account number itself is just one part of the full routing and account information you need to send or receive money. When you're setting up direct deposit, making a wire transfer, or authorizing an ACH payment, you'll usually need both your account number and Bank of America's routing number (which varies by state and account type).

Bank of America uses different routing numbers depending on where you opened the account and what type of account it is. The routing number is a nine-digit code that identifies the bank and the specific branch or processing center. Together, your routing number and 10-digit account number form the complete identifier for your account.

Key Takeaways

  • Bank of America checking account numbers are always 10 digits, found on checks or in your online account settings.
  • You need both your 10-digit account number and a 9-digit routing number to send or receive ACH transfers and direct deposits.
  • The routing number changes based on your account type and the state where you opened it, so verify it before authorizing payments.
  • Never share your full account number and routing number together with anyone you don't trust, as this combination can be used to withdraw money from your account.

Where to find your account number

The easiest place to locate your account number is on the bottom left of any check you have. The numbers appear in this order: routing number (9 digits), then account number (10 digits), then check number. If you don't have checks handy, log into your Bank of America online banking account or mobile app—your account number appears on the account summary page.

You can also call Bank of America customer service at 1-800-432-1000 and speak to a representative who can confirm your account number. Have your Social Security number and a form of identification ready when you call.

How the account number is used in transactions

When you set up direct deposit for your paycheck, your employer needs your routing number and account number. When you authorize an automatic bill payment through your bank, the biller receives the same information. ACH transfers between banks—whether you're sending money to a friend or paying a bill—require both numbers.

Wire transfers also use your account number, though the process is slightly different: the sending bank contacts Bank of America using the routing number, then references your account number to deposit the funds. If you're receiving a wire, you'll give the sender your routing number and account number, and sometimes your full name as it appears on the account.

When you write a check, the routing and account numbers are printed at the bottom in magnetic ink so they can be read by sorting machines. The check number itself is separate and appears on the right side of the bottom line.

What happens if someone has your account number

Your account number alone is not enough for someone to drain your account. They would also need your routing number, and even with both pieces of information, they cannot simply withdraw money without authorization. However, they could attempt to set up unauthorized ACH transfers or bill payments in your name.

If you believe your account number has been compromised, contact Bank of America immediately at 1-800-432-1000. You can request a new account number, though this involves closing your current account and opening a new one—a process that takes a few business days and requires updating any automatic payments or direct deposits tied to the old number.

Bank of America's fraud protection covers unauthorized transactions, but you must report suspicious activity within a specific timeframe. For ACH fraud, report it as soon as you notice it; for debit card fraud, you have up to 60 days from when your statement is sent to report it.

Routing numbers versus account numbers

The routing number identifies the bank or the specific processing center handling your account. Bank of America has multiple routing numbers depending on whether your account is a checking account, savings account, or money market account, and depending on the state where you opened it. The account number, by contrast, identifies your specific account within the bank.

Think of it this way: the routing number is like the address of the bank branch, and the account number is like your mailbox inside that branch. You need both to direct money to the right place. If you use the wrong routing number, your transfer may be delayed or rejected. If you use the wrong account number with the correct routing number, the money may go to someone else's account at Bank of America.

Keeping your account information secure

Never share your full account number and routing number together via email, text, or phone unless you initiated the contact and you're certain you're speaking with Bank of America or a trusted organization like your employer or a known biller. Scammers sometimes call pretending to be from the bank and ask for account information.

Bank of America will never ask you for your account number, PIN, or password via email or unsolicited phone call. If someone contacts you claiming to be from the bank and asking for this information, hang up and call the official Bank of America number on the back of your debit card or on your statement.

When you need to provide your account information for a legitimate purpose—setting up direct deposit, authorizing a payment, or receiving a wire—verify that you're communicating with the correct organization. Check the phone number or website independently rather than using contact information provided in an unsolicited message.

Frequently Asked Questions

Can I change my account number?

Bank of America can issue you a new account number, but this requires closing your current account and opening a new one. The process takes a few business days. You'll need to update your direct deposit, automatic bill payments, and any other recurring transactions tied to the old number. Contact Bank of America at 1-800-432-1000 to request this if you believe your account has been compromised.

What's the difference between my account number and my debit card number?

Your account number is 10 digits and identifies your checking account specifically. Your debit card number is 16 digits and is tied to your account but is a separate identifier used for card transactions. They are not the same, and someone with only your debit card number cannot access your account through ACH or wire transfers.

Do I need my routing number for every transaction?

You need your routing number for ACH transfers, direct deposits, and wire transfers. You do not need it for debit card purchases, ATM withdrawals, or checks (the routing number is already printed on the check). When in doubt, ask the organization requesting the information whether they need the routing number or just the account number.

What if I give someone the wrong account number?

If you provide an incorrect account number but the correct routing number, the money may be deposited into someone else's Bank of America account, or the transfer may be rejected. Contact the sender immediately and provide the correct account number. If money was deposited to the wrong account, Bank of America can sometimes recover it, but this requires the cooperation of the account holder who received it.

Is my account number the same as my customer ID?

No. Your customer ID is a separate number Bank of America uses to identify you as a customer across all your accounts. Your account number identifies a specific account. You may have multiple account numbers if you have checking, savings, and money market accounts, but you have one customer ID.
