Yes, but the account holder must authorize it first
You can deposit money into someone else's account, but the bank will not let you do it without their permission. Most banks require the account owner to add you as an authorized user, set up a transfer rule, or give you explicit written consent before you can move money in. Some banks allow deposits without authorization if you use their mobile app or ATM and have the account number and routing number, but this varies by institution and is not may provide to work.
The safest and most direct method is to ask the account holder to add you as a joint account holder or authorized depositor. This takes a few days to process and requires them to visit the bank or complete an online form with you present. Once approved, you can deposit cash, checks, or transfers into the account without additional permission each time.
Key Takeaways
- The account owner must authorize you before you deposit money into their account, either by adding you as an authorized user or by giving written consent.
- You can deposit cash or checks at an ATM or teller window if the account holder has added you to the account, but mobile app deposits usually require their login credentials.
- Wire transfers and ACH transfers into someone else's account require the account number, routing number, and the account holder's permission.
- If you deposit money without authorization, the bank may freeze the account or reject the deposit, and the account holder may report it as fraud.
- Some banks allow third-party deposits through their mobile app if you have the account details, but this is not standard across all institutions.
Adding yourself as an authorized user or joint account holder
The most straightforward way to deposit money into someone else's account is to have them add you as an authorized user or joint account holder. The account owner goes to their bank in person or logs into their online banking portal and requests to add you. They will need your name, date of birth, address, and Social Security number. The bank will verify your identity and may run a background check.
As an authorized user, you can deposit money but may not have full access to withdraw funds or close the account, depending on the bank's rules. As a joint account holder, you have equal rights to the account and can deposit, withdraw, and manage it as if it were your own. The account owner should be clear about which role they want you to have before you visit the bank together.
This process usually takes three to five business days. Once you are added, you can deposit cash at any ATM or teller window, deposit checks through the mobile app (if the bank offers mobile check deposit), or transfer money electronically.
Depositing cash or checks without being on the account
If you are not an authorized user, you can still deposit cash or a check into someone else's account at a physical bank branch. Walk into the bank with the cash or check and tell the teller you want to deposit it into another person's account. You will need to provide the account holder's name and account number. The teller will process the deposit and give you a receipt.
Some banks allow third-party check deposits through their mobile app if you have the account number and routing number, but this is not universal. Check your bank's mobile app to see if this option is available. If it is not, you will have to go to a branch or ATM.
ATM deposits are less reliable for third-party deposits. Most ATMs are programmed to accept deposits only into the account holder's own card, but some banks have updated their machines to accept deposits into other accounts if you enter the account number manually. Call the bank ahead of time to confirm whether their ATMs support this.
Sending money via wire transfer or ACH
You can send money electronically into someone else's account using a wire transfer or an ACH transfer. Both methods require the account holder's bank account number and routing number. You initiate the transfer from your own bank account or through a money transfer service.
Wire transfers move money the same business day or within one to two business days, depending on the time you send it and the banks involved. ACH transfers take three to five business days. Neither method requires the account holder to authorize the transfer in advance — the money goes in based on the account details you provide. However, if the account number or routing number is wrong, the transfer may be rejected or sent to the wrong account.
The account holder does not need to do anything on their end to receive the money. It will appear in their account automatically once the transfer clears. If they are concerned about where the money came from, they can contact their bank to trace the transfer back to you.
What happens if you deposit money without permission
If you deposit money into someone else's account without their knowledge or consent, the bank may flag the transaction as suspicious. Banks monitor for unusual activity, and a deposit from an unknown third party can trigger a review. The account holder may receive a notification asking them to confirm the deposit.
If the account holder reports the deposit as unauthorized or fraudulent, the bank will investigate and may reverse the transaction. The money will be returned to your account, and the bank may close the account or restrict it. In rare cases, the account holder could report you to law enforcement, though this is uncommon for a single deposit.
To avoid this, always get permission from the account holder before depositing money into their account. A quick text, email, or phone call confirming that they want to receive the deposit protects both of you.
Depositing money into a minor's account
If you want to deposit money into a child's account, the rules depend on how the account is set up. Most children's accounts are owned by a parent or guardian, and you will need that adult's permission to deposit money. Some banks allow grandparents, relatives, or family friends to deposit cash or checks at a branch without being on the account, but you will still need to provide the child's name and account number.
If the account is a custodial account (held in trust for the child), only the custodian can authorize deposits. If it is a joint account with the parent, either parent can authorize a deposit from you. Ask the parent which type of account it is before you try to deposit money.
Frequently Asked Questions
Can I deposit a check into someone else's account if I sign the back?
No. If a check is made out to someone else, you cannot deposit it into your own account even if you sign the back. You can deposit it into the payee's account at a bank branch by giving it to the teller along with their account number. The payee does not need to sign it or be present.
What if the bank rejects my deposit into someone else's account?
The bank may reject the deposit if the account number is wrong, the account is closed, or the account holder has restrictions on third-party deposits. Contact your bank to find out why the deposit was rejected. If the account number was incorrect, ask the account holder to confirm it and try again.
Do I need the account holder's permission to send them money via wire transfer?
No. You only need their account number and routing number to send a wire transfer. However, it is good practice to tell them you are sending money so they know to expect it and can confirm it arrived.
Can I deposit money into someone else's account at a different bank?
Yes. You can deposit money into any bank account in the United States as long as you have the account number and routing number. The banks do not have to be the same. Wire transfers and ACH transfers work across all banks.
What if I want to deposit money regularly into someone else's account?
Set up a recurring ACH transfer or standing order from your bank. You provide the account holder's account number and routing number once, and the bank will transfer the same amount on the same day each month. This is common for parents sending money to adult children, employers sending reimbursements, or family members sharing expenses.
