Bank account details are the identifying information a bank uses to find your account and move money in or out
Your bank account details are a set of numbers and codes that tell any bank or payment system exactly which account to send money to or pull money from. They are not your password or your login. They are the address of your account — the information you give to your employer, a creditor, or anyone else who needs to put money into your account or take money out of it.
The core details are your routing number (a nine-digit code that identifies your specific bank branch) and your account number (a number unique to your account at that bank, usually 8 to 12 digits). Together, these two pieces tell the payment system where your money goes. Many banks also ask for your name as it appears on the account, as a final check that the money is going to the right person.
Key Takeaways
- Your routing number identifies your bank branch; your account number identifies your specific account within that bank.
- You can find both numbers on the bottom left of any check you write, or by logging into your online banking or calling your bank.
- Bank account details are safe to share with employers, creditors, and payment systems — they do not give anyone access to withdraw money without your permission.
- Different types of accounts (checking, savings, money market) may have different account numbers at the same bank, so always use the number for the account you want the money to go to.
- Your bank account details are different from your debit card number, PIN, or online banking password — never share those.
Where to find your routing number and account number
The easiest place to find both numbers is on a check. Look at the bottom left corner of any check from your account. You will see three groups of numbers separated by colons or vertical lines. The first group (nine digits) is your routing number. The second group is your account number.
If you do not have checks, log into your online banking portal or mobile app. Most banks display your account number on the dashboard or in an account summary section. Some banks label it "Account Number" or "DDA Number" (demand deposit account). Your routing number is usually listed under "Bank Information" or "Account Details," or you can call your bank's customer service line and ask.
You can also search for your bank's routing number online by entering your bank name and state. The American Bankers Association maintains a routing number database, and many banks publish theirs on their website.
Why you need to give out your account details
You provide your bank account details whenever you want money to move electronically into or out of your account. Common situations include setting up direct deposit for your paycheck, authorizing an automatic bill payment, requesting a refund to your bank account, or sending money through a peer-to-peer payment app that requires bank account information.
You also need to provide these details when you open a new account at a different bank and want to transfer money from your old account, or when you are setting up an automatic transfer to a savings account. Any time the payment system needs to know where your money is, you are giving out your account details.
What account details do and do not let someone do
Your routing number and account number tell a payment system where to send money, but they do not give someone the ability to log into your account, change your password, or see your balance. They are like your mailing address — anyone can send you mail there, but knowing your address does not let them open your mailbox or read your mail.
Someone with your account details can set up a payment to your account (which is usually what you want) or, in rare cases, attempt to set up an unauthorized withdrawal. This is why you should only give your account details to people and organizations you trust. If you suspect someone has misused your account details, contact your bank immediately. Federal law limits your liability for unauthorized transfers if you report them within a certain timeframe, usually 60 days.
Your account details are different from sensitive information like your PIN, online banking password, or debit card number. Never share those with anyone, including your bank (your bank will never ask for your password).
Account details for different account types
If you have more than one account at the same bank — for example, a checking account and a savings account — each account has its own account number. Your routing number stays the same because it identifies the bank branch, not the individual account.
When you give out your account details, make sure you are using the account number for the account you want the money to go to. If you tell your employer to deposit your paycheck into your savings account, you need to give them your savings account number, not your checking account number. If you mix them up, your money will go to the wrong account, and you will have to contact your employer or the bank to fix it.
Protecting your account details
While your account details are generally safe to share with legitimate organizations, you should still be cautious about who you give them to. Only provide them to people and companies you recognize and trust — your employer, your bank, a creditor you owe money to, or a payment system you have chosen to use.
Be wary if someone calls you out of the blue asking for your account details. Scammers sometimes pose as banks or creditors to trick people into giving out this information. If you are unsure whether a caller is legitimate, hang up and call your bank directly using the number on your bank statement or card.
If you lose a check or think someone has seen your account details without permission, contact your bank. They can monitor your account for suspicious activity and, if necessary, close the account and open a new one with a new account number.
Frequently Asked Questions
Is it safe to give my account details to my employer?
Yes. Your employer needs your routing number and account number to set up direct deposit. This is one of the most common and secure uses of your account details. Your employer cannot access your account or withdraw money without your authorization.
What if I give someone the wrong account number?
The payment will likely be rejected or sent to the wrong account. If money goes to the wrong account, contact the organization that sent it and ask them to reverse the transaction. Your bank can also help trace the payment and request a return.
Do I need to give my account details to use a debit card?
No. Your debit card has its own number printed on it, and that is what you use to make purchases or withdraw cash. You only need to provide your routing number and account number for electronic transfers and direct deposits.
Can someone steal money from my account if they know my account number?
It is unlikely without additional information, but it is possible. Most unauthorized withdrawals require more than just your account number — they often involve fraud or a compromised payment system. If you suspect fraud, contact your bank right away. Federal law protects you from most unauthorized transfers if you report them within 60 days.
What is the difference between my account number and my debit card number?
Your account number is used for electronic transfers and direct deposits. Your debit card number is a separate number printed on your card and used for purchases and ATM withdrawals. They are not the same, and you should never share your debit card number the way you share your account details.
