Yes, other people can deposit money into your account without your permission, as long as they know your account number and routing number
Anyone with your account number and routing number can send you money directly into your bank account. They do not need your permission first, and you do not need to approve the deposit. The money lands in your account automatically, usually within one to three business days depending on how they send it.
This is one of the simplest ways to receive money from family, friends, employers, or government programs. You do not have to be present, sign anything, or take any action. The sender handles everything on their end.
Key Takeaways
- Your account number and routing number are all someone needs to deposit money into your account — you cannot prevent a deposit once they have this information.
- Direct deposit from employers and government programs uses the same account and routing number method and is the most common way money enters accounts.
- Bank transfers, wire transfers, and ACH transfers are different methods people use to send you money, each with different timing and costs.
- Sharing your account and routing number is safe for receiving money, but never share your PIN, password, or the back of your debit card.
The two pieces of information someone needs to send you money
Your routing number is a nine-digit code that identifies your specific bank or credit union. Every bank has one. Your account number is unique to you and is usually 10 to 12 digits long. Together, these two numbers tell the sender's bank exactly where to send the money.
You can find both numbers on the bottom left of any check you have from your account. The routing number comes first (nine digits), then your account number. If you do not have checks, call your bank or log into your online account — both will show you these numbers. You can also ask a teller in person.
It is safe to share these two numbers with anyone who needs to send you money. They cannot withdraw funds, change your password, or access your account in any other way with just these numbers. They can only put money in.
Direct deposit: the most common way money enters your account
Direct deposit is when an employer, government program, or other organization sends your money straight into your account on a regular schedule. Your paycheck, tax refund, Social Security payment, or unemployment benefit can all arrive this way. You give the organization your account and routing number once, and the money shows up automatically on payday or the scheduled date.
Direct deposit is faster and more reliable than a paper check. The money usually arrives one or two business days before the official payment date. You do not have to go anywhere or do anything — it just happens. Most employers now offer direct deposit, and many government programs require it or strongly encourage it.
To set up direct deposit, you typically fill out a form at work or on a government website. The form asks for your account number, routing number, and the type of account (checking or savings). Once it is set up, you do not need to do anything again unless you change banks.
Bank transfers and ACH transfers: how friends and family send you money
When someone sends you money from their own bank account, they are usually doing an ACH transfer (Automated Clearing House). This is a system that moves money between banks electronically. The sender goes into their bank's website or app, enters your account and routing number, picks an amount, and schedules the transfer. The money arrives in your account in one to three business days.
ACH transfers are free or very cheap — usually $0 to $1 per transfer. They are slower than some other methods, but they work for everyday situations like splitting rent with a roommate, paying back a friend, or receiving money from family. Most banks let you receive unlimited ACH transfers with no fees.
Some banks also let you send money through their own system using just a phone number or email address, without needing account numbers. This is sometimes called a bank transfer or peer-to-peer transfer. The exact process depends on your bank, but the result is the same — money moves from their account to yours in a day or two.
Wire transfers: faster but more expensive
A wire transfer is a faster way to send money, usually arriving the same day or next business day. The sender goes to their bank in person or online, provides your account and routing number, and the bank sends the money through a separate system. Wire transfers cost more — usually $15 to $30 — so people use them when speed matters, like for a down payment on a house or an urgent payment.
You do not need to do anything to receive a wire transfer. The money arrives in your account automatically. If you are expecting a large wire transfer, you can call your bank ahead of time to let them know, but it is not required. Some banks may hold large wire transfers for a day while they verify them, but this is rare.
What you should never share about your account
Your account and routing number are safe to share. But there are other pieces of information you should keep completely private. Never give anyone your PIN (personal identification number), your online banking password, or the three-digit security code on the back of your debit card. These allow someone to withdraw money or make purchases, not just deposit.
Also do not share photos of your entire debit card, checks with your full information, or your Social Security number unless you are sure you are dealing with your bank or a trusted organization. If someone asks for these things to send you money, they are asking for something they do not need — that is a sign something is wrong.
What happens if someone sends you money by mistake
If someone deposits money into your account by mistake — the wrong account number, a duplicate payment, or a genuine error — the money is still yours to use until the sender or their bank asks for it back. You are not required to refuse it or report it when ready.
However, if the sender or their bank discovers the mistake and asks you to return it, you are legally required to do so. If you have already spent the money, you may face a dispute with the bank. The safest approach is to contact your bank as soon as you realize a mistake has happened and ask what to do. Your bank can help you return the money or hold it while things get sorted out.
Frequently Asked Questions
Can someone deposit money into my account if they only know my name and bank?
No. They need your specific account number and routing number. Knowing just your name and bank is not enough — there are thousands of accounts at each bank. They must have the nine-digit routing number and your account number to send money to you.
Does the money show up right away when someone sends it?
Not usually. ACH transfers and bank transfers take one to three business days. Wire transfers are faster, usually arriving the same day or next day. The exact timing depends on when the sender initiates the transfer and your bank's processing schedule. Weekends and holidays can add extra days.
What if I give someone my account number and they take money out instead of putting it in?
They cannot withdraw money with just your account and routing number. Those numbers only allow deposits. To withdraw or transfer money out, someone would need your PIN, password, or debit card — which you should never share. If money goes missing from your account, contact your bank when ready to report unauthorized activity.
Is it safe to give my account number to my employer for direct deposit?
Yes. Your employer needs your account and routing number to set up direct deposit, and this is a standard, safe practice. Millions of people do this every day. Your employer cannot access your account or withdraw money with just these numbers.
Can I receive money from outside the United States?
Yes, but the process is different and slower. International wire transfers can take five to ten business days and usually cost $15 to $50. The sender's bank and your bank both charge fees. For smaller amounts, some people use services like PayPal or Wise, which may be cheaper and faster. Ask your bank what options they offer for international transfers.
