The main ways to deposit money into checking
You can deposit money into a checking account through your bank's ATM, at a teller window during business hours, by mailing a check, through a mobile app, or by having money transferred directly from another account or employer. The method you choose depends on how much money you're depositing, how quickly you need it available, and what your bank offers.
Each method has different timing — some deposits show up instantly, others take one to three business days. ATM deposits and mobile deposits usually process overnight, while mailed checks can take five to seven business days to clear.
Key Takeaways
- ATM deposits and teller deposits are the fastest in-person methods, with funds often available the same day or next business day.
- Mobile check deposit through your bank's app lets you photograph a check and submit it from home, typically clearing within one business day.
- Direct deposit from your employer or government payments goes straight into your account and is the most reliable method for regular income.
- Mailed checks take the longest — usually five to seven business days — and should only be used when other options aren't available.
- Some banks charge fees for certain deposit methods or limit how many deposits you can make per month, so check your account terms.
Depositing at an ATM or bank branch
The simplest way to deposit cash or a check is at your bank's ATM or at a teller window. ATMs are available 24/7 at most banks, while teller windows operate during business hours — usually 9 a.m. to 5 p.m. on weekdays and limited Saturday hours. Insert your debit card, enter your PIN, select "deposit," and follow the on-screen instructions. For checks, the ATM will scan both sides and return the check to you immediately.
Cash deposits at an ATM are available right away, usually within minutes. Check deposits typically post by the next business day, though some banks make a portion available sooner. At a teller window, you can deposit cash or checks and ask questions if something seems wrong with the check. Tellers can also deposit large amounts of cash without the limits some ATMs have.
Using mobile check deposit
Most banks offer a mobile app that lets you photograph the front and back of a check and submit it without visiting a branch. Open your bank's app, find the deposit or mobile check feature, take clear photos of both sides of the check, and submit. The app will tell you the deposit amount and when it will be available.
Mobile deposits usually clear within one business day. Some banks make a portion of the deposit available immediately and the rest the next day. You'll receive a confirmation number and can delete the photos from your phone once the deposit is confirmed. Do not deposit the physical check again — most banks require you to write "deposited" on the check and keep it for 30 days before destroying it, in case the bank needs proof.
Setting up direct deposit
Direct deposit is when money from your employer, the government, or another source transfers automatically into your checking account on a set schedule. To set it up, you'll need to give your employer or the paying organization your bank's routing number and your account number. Both numbers appear on the bottom left of your checks, or you can find them by logging into your online banking or calling your bank.
Direct deposit is the most reliable deposit method because it happens automatically and doesn't require you to do anything each time. Funds usually appear on the scheduled date or one business day before. If you receive a paycheck, tax refund, or government payment like Social Security, setting up direct deposit means you don't have to visit a bank or use an app — the money just arrives.
Transferring money from another account
You can move money from another bank account into your checking account through an online transfer. Log into your bank's website or app, select "transfer," and choose the account you want to send money from. You'll need the routing number and account number of the other bank. Most transfers between accounts at different banks take one to three business days.
Transfers between two accounts at the same bank usually happen instantly or within hours. If you're transferring from a savings account to a checking account at the same bank, the money is often available immediately. Some banks limit how many transfers you can make per month from a savings account, though transfers into a checking account usually don't count against that limit.
Depositing cash or checks by mail
Mailing a check or cash to your bank is the slowest deposit method and should only be used when you have no other option. Write your account number on the back of the check, place it in an envelope with a deposit slip (available from your bank's website or by calling), and mail it to the address your bank provides. Cash should never be mailed — it can be lost or stolen in transit.
Mailed checks typically take five to seven business days to clear, sometimes longer depending on the check's origin and your bank's processing schedule. You won't receive a receipt, so keep a copy of the deposit slip or take a photo of the check before mailing it. Track your account to confirm the deposit posted before assuming it was lost.
Understanding deposit limits and fees
Some banks limit how much you can deposit through certain methods. ATMs may have daily cash deposit limits of $1,000 to $10,000, and mobile check deposits often cap at $2,500 to $5,000 per check or per day. These limits vary by bank and account type. Teller deposits and direct deposits usually have no limits.
Most banks don't charge fees for standard deposits, but some charge for services like mobile check deposit or for depositing at an ATM outside their network. Check your account agreement or call your bank to learn what deposit methods are free and what limits apply to your account. If you frequently deposit large amounts, ask whether your bank offers a business checking account, which may have higher limits and different fee structures.
What to do if a deposit doesn't show up
If you deposited money and it hasn't appeared after the expected time, first check your account online or call your bank to confirm the deposit was received. If it was received but hasn't posted, wait until the next business day — some deposits take longer than expected. If the deposit was rejected, your bank will send you a notice explaining why, usually because the check was damaged, the amount was illegible, or the check was already deposited elsewhere.
If a deposit is missing and your bank has no record of it, contact your bank immediately with the date, amount, and method of deposit. If you used an ATM, your bank can review the ATM footage. If you mailed a check, file a claim with your bank and contact the sender to request a replacement check. Keep records of all deposits — photos, receipts, or confirmation numbers — so you can prove what you deposited if there's a dispute.
Frequently Asked Questions
How long does it take for a check to clear after I deposit it?
Most checks clear within one to three business days. ATM and teller deposits usually post by the next business day, while mailed checks take five to seven days. Some banks make a portion of the deposit available immediately and hold the rest until the check fully clears.
Can I deposit a check that's made out to someone else?
No. A check must be deposited into an account in the name of the person it's written to. If someone gives you a check made out to them, they must sign the back and write "pay to the order of [your name]," then you sign below that. Not all banks accept third-party checks, so call yours first.
What happens if I deposit a check twice by accident?
Your bank will catch the duplicate and reject the second deposit, or it will post and then be reversed a few days later. You'll see a debit for the reversed amount. If you're unsure whether a check cleared, log into your account online or call your bank before depositing it again.
Is it safe to mail cash to my bank?
No. Cash can be lost or stolen in the mail and there's no way to prove you sent it. Always use a deposit method that creates a record — ATM, teller, mobile app, or direct deposit. If you must send money by mail, use a cashier's check or money order instead.
Do I need to keep the physical check after I use mobile deposit?
Yes, for at least 30 days. Write "deposited" on the check and keep it in case your bank needs proof of the deposit. After 30 days, you can shred or destroy it. Don't deposit the physical check again at an ATM or teller — that creates a duplicate deposit.
