You can deposit money at your own bank's branches and ATMs, but depositing at another bank's location depends on whether you have an account there and what type of deposit it is
The short answer: deposit at your bank. If you need to deposit elsewhere, your options narrow fast. You can deposit cash or checks at your own bank's branches and ATMs during business hours. You can also mail checks to your bank or use mobile deposit (photographing the check through an app). If you try to walk into a different bank and deposit money into your account, they will usually refuse — they do not process deposits for accounts held elsewhere.
The confusion happens because banks used to share deposit networks. That changed. Today, most banks are closed networks: they accept deposits only for accounts they hold. A few exceptions exist, but they are shrinking, and the rules around them are strict.
Key Takeaways
- Your own bank accepts deposits at all its branches and most of its ATMs during the hours they operate.
- Other banks will not accept a deposit into your account unless you have an account with them, even if you have the routing and account numbers.
- Mobile deposit and mailed checks let you deposit without visiting a branch, and most banks process them within one to three business days.
- Some credit unions and online banks participate in shared branching networks, allowing deposits at partner locations, but you must check your specific institution.
- ATM deposits at your bank are usually available 24/7, but the funds may not post until the next business day.
Depositing at your own bank's locations
Your bank's branches accept deposits during their posted hours — typically 9 a.m. to 5 p.m. on weekdays, with shorter Saturday hours at many locations. You can deposit cash or checks. Bring your debit card or account number so the teller can route the money to the right account. Most banks process branch deposits the same day if you arrive before a cutoff time (often 2 p.m.), though some post them the next business day.
ATM deposits work around the clock. You insert cash or checks into the machine, and it scans and holds the deposit. The bank verifies the amount and posts it to your account, usually by the next business day. Some banks post ATM deposits the same day if you deposit before a certain time. Check your bank's website or app to see the cutoff and whether your specific ATM accepts deposits — not all do.
Why other banks will not accept your deposit
Banks are separate businesses with separate accounting systems. When you deposit money at Bank A into an account held at Bank B, Bank A has no way to verify your account exists, no way to confirm you are the account holder, and no obligation to process the transaction. They also cannot may provide the money will reach the right place. For these reasons, most banks stopped accepting third-party deposits decades ago.
The risk is real: if you hand cash to a teller at the wrong bank and claim it is for your account elsewhere, the bank has no proof you own that account. If the money goes missing, you have no recourse against them. They protect themselves by refusing the deposit outright.
Shared branching networks for credit unions and some online banks
Some credit unions and a handful of online banks participate in shared branching networks, which allow members to deposit at partner locations. The two largest networks are CO-OP and Alliant. If your credit union or online bank is part of one of these networks, you can walk into a participating branch and make a deposit to your account, even though you do not have an account at that location.
To use shared branching, bring your debit card or account number and a photo ID. The teller will verify your account through the network and process the deposit. Funds typically post within one to three business days. Not all credit unions or online banks participate, so check your institution's website or call to confirm whether shared branching is available to you and where the nearest partner branch is located.
Mobile deposit and mailed checks
Mobile deposit lets you photograph the front and back of a check using your bank's app and submit it without visiting a branch. Most banks offer this for free. The check must be endorsed (signed on the back) and the image must be clear and legible. Processing usually takes one to three business days, though some banks post mobile deposits the next business day.
Mailing a check is slower but works with any bank. Write your account number on the back of the check, place it in an envelope with a deposit slip (available on your bank's website or at a branch), and mail it to the address your bank provides. Processing takes five to ten business days depending on mail delivery and your bank's processing schedule. Do not mail cash — it can be lost or stolen in transit.
What happens if you try to deposit at the wrong bank
If you walk into a bank where you do not have an account and ask to deposit money into your account elsewhere, the teller will tell you they cannot process it. They may suggest you visit your own bank or use mobile deposit. If you insist or try to leave the money anyway, they will refuse and may ask you to leave.
Some older readers may remember when banks belonged to regional networks and accepted deposits from each other. Those networks are gone. A few independent banks still have reciprocal agreements with nearby banks, but these are rare and you would need to ask your bank directly whether such an agreement exists.
Timing and posting rules for deposits
Deposits made at a branch before the cutoff time (usually 2 p.m.) often post the same day. Deposits made after the cutoff or on weekends post the next business day. ATM deposits and mobile deposits typically post the next business day, though some banks are faster. Check your bank's deposit policy on its website or in your account app — most banks show the expected posting date when you make the deposit.
The Expedited Funds Availability Act requires banks to make certain deposits available within a set number of business days, but the timeline depends on the deposit type. Cash deposits must be available by the next business day. Local checks must be available within two business days. Remote checks (from banks far away) may take up to five business days. Your bank's policy may be faster than these minimums.
Frequently Asked Questions
Can I deposit a check at a different bank if I endorse it to someone else?
No. Third-party checks — checks endorsed to you and then signed over to someone else — are rarely accepted by any bank today, including your own. Most banks refuse them because they create fraud risk and verification problems. Deposit the check into your own account and then transfer the money to the other person instead.
What if I need to deposit cash urgently and my bank is closed?
Use your bank's ATM if it accepts cash deposits — most do and operate 24/7. If your bank's ATM does not accept deposits, you will need to wait until the branch opens. No other bank will accept the deposit for you. Some banks offer Saturday hours; check your branch's schedule online.
Do online banks have physical locations where I can deposit?
Most online banks have no physical branches. They accept deposits through mobile deposit, mailed checks, or transfers from other accounts. Some online banks partner with shared branching networks, allowing deposits at credit union branches. Check your bank's website to see what deposit methods are available.
Can I deposit money into someone else's account at my bank?
Yes, if you both have accounts at the same bank. You can deposit cash or checks into their account at a branch, and the teller will route it to their account number. You do not need their permission, but they will see the deposit in their account. For security, some people prefer to transfer money electronically instead.
What if my bank's ATM is broken and I need to deposit before the branch closes?
Go to the branch and deposit with a teller. If the branch is also closed or too far away, use mobile deposit if you have checks, or wait until the next business day. If you have cash and no other option, hold it safely until you can reach your bank — no other bank will accept it for you.
