ATM check deposits work like this: you insert your card, select deposit, scan or insert the check, and the machine reads it and credits your account

Most ATMs that accept deposits will take a check without an envelope. You insert your debit card, navigate to "Deposit" or "Make a Deposit," and either feed the check into a slot or place it on a scanner — the machine reads the check image and amount, then asks you to confirm. The check goes into a secure compartment, and the funds typically appear in your account within one business day, though some banks hold them for two to three days depending on the check amount and your account history.

Not every ATM has this feature. Older machines and those at smaller branches or credit unions may only dispense cash. Your bank's website or app usually shows which ATMs near you have deposit capability, or you can call your branch to confirm before you go.

Key Takeaways

  • Check deposits at ATMs are read by machine and usually post to your account within one business day, though holds of two to three days are common for larger amounts.
  • Your card must be enrolled in mobile or online banking with your bank, and the ATM must be owned by your bank or a network partner — deposits at out-of-network ATMs typically are not accepted.
  • Checks must be signed on the back, made out to you or your account name, and free of damage or writing in the MICR line at the bottom.
  • If the machine rejects your check, take it to a teller or try a different ATM — some machines are more reliable than others, and tellers can deposit checks that machines cannot read.

What your bank requires before you can deposit at an ATM

You need an active debit card linked to a checking account at that bank, and your account must be set up for online or mobile banking. Some banks require you to turn on mobile deposit or ATM deposit in your app or online portal before your first use — this is a security step, not a barrier, and takes less than a minute.

The ATM must belong to your bank or to a network your bank participates in. Bank of America, Wells Fargo, Chase, and most large banks are part of shared networks, so you can use their ATMs even if you bank elsewhere. Credit unions often belong to CO-OP or Allpoint networks. If you use an ATM owned by a bank you do not have an account with and that bank is not in your network, the machine will reject the deposit.

How to prepare your check

Sign the back of the check in the space marked "Endorse here." Write your account number below your signature — this is optional but helps if the machine misreads the check number. Do not write anything in the magnetic ink character recognition (MICR) line, which is the row of numbers at the very bottom of the check; machines cannot read checks with marks or writing there.

Check that the check is made out to you or to your account name. Checks made out to a business name, a former name, or a name that does not match your account will be rejected. If the check is damaged, torn, or has ink smudges on the front, the machine may not read it — take it to a teller instead.

Step-by-step: depositing at the ATM

Insert your debit card and enter your PIN. Navigate the menu to "Deposit," "Make a Deposit," or "Check Deposit" — the exact wording varies by bank. The machine will ask you to choose your account (usually checking) and may ask you to enter the deposit amount or let the machine read it.

Place the check face-up in the slot or on the scanner, depending on the machine type. Some machines have a slot you feed the check into; others have a flat glass surface where you lay the check down. The machine will scan the check, display the amount it read, and ask you to confirm. Review the amount — if it is wrong, cancel and try again or take the check to a teller. Once you confirm, the machine will accept the check and print a receipt showing the deposit amount and your new balance.

How long the deposit takes to post

Most banks post ATM check deposits within one business day. If you deposit on a Friday evening, the check may not post until Monday. Deposits made after business hours (usually 9 p.m. or later) are often treated as next-day deposits even if you make them early in the morning.

Holds are common for checks over a certain amount — often $5,000 or more, though this varies by bank and your account history. A hold means the bank credits the deposit to your account but does not let you withdraw the funds until the check clears, which usually takes two to three business days. Your receipt or online banking will show whether a hold is in place.

What to do if the machine rejects your check

The machine will display an error message and return your check. Common reasons are a missing signature, damage to the check, writing in the MICR line, or the check being made out to a name that does not match your account. Review the check against the requirements above and try a different ATM if one is nearby — some machines are more sensitive than others and may accept a check that another machine rejected.

If a second machine also rejects it, take the check to a teller during business hours. Tellers can deposit checks that machines cannot read, and they can also help if the check is made out to a slightly different version of your name or if there is a question about the account it should go into. This is not a problem — tellers handle rejected ATM deposits regularly.

ATM deposits versus mobile check deposits

Mobile check deposits (photographing a check with your phone) are faster to initiate — you can do it from home — but ATM deposits are more reliable because the machine reads the actual check, not a photo. Mobile deposits sometimes fail because of poor lighting, camera angle, or image quality, and you have to retake the photo and resubmit. ATM machines read the check directly and give you immediate feedback on whether it worked.

Both methods post within one business day on average. If you have a choice and the ATM is convenient, ATM deposits are less likely to fail. If you are depositing a check late at night or from home, mobile deposit is your only option.

Frequently Asked Questions

Can I deposit a check made out to someone else?

No. The check must be made out to you or to your account name. If a check is made out to another person, they must sign it and deposit it into their own account, or they can sign it over to you in writing (called a third-party endorsement), though many banks no longer accept third-party checks for security reasons.

What if the ATM keeps rejecting my check?

Take it to a teller. The machine may be malfunctioning, or the check may have a flaw the machine cannot read but a teller can work around — a slightly faded signature, minor damage, or a name variation. Tellers have options machines do not.

Do I get the check back after I deposit it?

No. The ATM keeps the check in a secure compartment, and your bank stores it or destroys it after the funds clear. You do not need the physical check after deposit — your receipt and online banking record are your proof of deposit.

Can I deposit a check at an ATM that is not my bank?

Only if your bank is part of the same network. Most large banks share networks, so you can use their ATMs. Credit unions have their own networks. If the ATM belongs to a bank you do not have an account with and that bank is not in your network, the machine will reject the deposit.

Why is my check on hold?

Banks place holds on checks to protect against fraud or insufficient funds. Holds are common for large checks, checks from out-of-state banks, or if your account is new. The hold does not mean the deposit failed — the money is in your account, but you cannot withdraw it until the check clears, usually two to three business days.
