To deposit a check with your phone, you open your bank’s mobile app, navigate to the deposit feature, endorse the back of the check, snap photos of both sides, enter the amount, and submit. The whole process takes about two minutes once you know what to expect. Here’s how to do it right the first time and avoid the most common reasons deposits get rejected.
What You Need Before You Start
You’ll need three things: the physical check, a smartphone with your bank’s mobile app installed, and a bank account that’s already enrolled in mobile deposit. Most banks enable mobile deposit automatically when you download their app and log in, but some require you to opt in through your account settings or by calling customer service.
Make sure your app is updated to the latest version. Older versions can cause glitches with the camera feature or fail to load the deposit screen entirely.
How to Endorse the Check
Before you photograph anything, flip the check over and sign your name on the back in the endorsement area, which is the short section of lines near one end. Directly beneath your signature, write “For Mobile Deposit Only.” Some banks also want you to add your account number or the bank’s name below that line, so check your app’s instructions if you’re unsure.
This endorsement is important. It restricts the check so it can only be processed as a mobile deposit to your account, which protects you if the check is lost or stolen. A missing or incorrect endorsement is one of the top reasons mobile deposits get rejected.
Step-by-Step Deposit Process
The exact screen layout varies by bank, but the flow is nearly identical everywhere:
- Open the app and log in. Find the deposit option, which is usually labeled “Deposit,” “Mobile Deposit,” or “Deposit Checks” on the main menu or bottom navigation bar.
- Select the account. If you have more than one account (checking and savings, for example), choose which one should receive the funds.
- Enter the check amount. Type the dollar amount exactly as it appears on the check. If the amount you enter doesn’t match what the bank reads from the check image, the deposit will be refused.
- Photograph the front of the check. The app will activate your camera. Place the check on a dark, flat surface with good lighting. Align it inside the on-screen guide and hold steady until the app captures the image. Some apps snap the photo automatically when the alignment looks right.
- Photograph the back of the check. Flip the check over, making sure your endorsement and “For Mobile Deposit Only” are visible, and take the second photo the same way.
- Review and submit. The app will show you both images. Confirm the amount and account are correct, then tap submit or deposit.
You should see a confirmation screen with a reference number or confirmation code. Take a screenshot or write it down in case you need it later.
Tips for Clear Check Photos
Image quality is the single biggest factor in whether your deposit goes through or gets kicked back. A check image that isn’t readable, or a MICR line (the string of numbers printed along the bottom edge of the check) that comes out blurry, will cause a rejection.
Place the check on a dark, non-reflective surface like a desk or countertop. A white check on a white table confuses the camera’s auto-focus. Make sure overhead lighting is even and avoid shadows from your hand or phone falling across the check. Hold your phone directly above and parallel to the check rather than at an angle. If the check is folded or creased, flatten it as much as possible before photographing. Torn or heavily wrinkled checks often can’t be processed through mobile deposit at all.
Deposit Limits
Every bank sets its own daily and monthly caps on mobile deposits. These limits vary widely depending on the institution, your account type, and how long you’ve been a customer. A common range for daily limits is $2,500 to $10,000, though some banks start new customers at lower thresholds and raise them over time. If you need to deposit a check that exceeds your mobile limit, you’ll need to visit a branch or ATM instead.
You can usually find your specific limit inside the mobile deposit section of your app, or by checking your bank’s website under mobile deposit FAQs.
When Your Money Becomes Available
Don’t expect to spend the full amount immediately. Federal rules under Regulation CC require banks to make the first $225 of most check deposits available by the next business day, but the rest can take longer. For standard checks, banks typically release the remaining funds within two business days. However, banks are allowed to place extended holds on certain deposits, particularly large ones. For any deposit where the amount exceeds $6,725, your bank can hold the portion above that threshold for a longer “reasonable” period, which often means up to seven business days.
In practice, many banks release mobile deposit funds faster than the legal maximums, especially for established customers with a history of good deposits. Your confirmation screen or receipt will often tell you the expected availability date.
What to Do With the Paper Check
After you submit the deposit, write “mobile deposit” and the date on the front of the paper check. This prevents you (or anyone else) from accidentally depositing it a second time. Keep the physical check until the deposit has fully cleared in your account, which typically takes several days. Once the funds appear and your bank hasn’t flagged any issues, shred the check. Don’t just throw it in the trash, since it contains your name, the payer’s account number, and routing information.
Common Reasons Deposits Get Rejected
If your deposit doesn’t go through, the app will usually tell you why. The most frequent causes are straightforward to fix:
- Blurry or unreadable image. Retake the photo with better lighting and a steadier hand.
- Missing endorsement. Make sure you’ve signed the back and written “For Mobile Deposit Only.”
- Amount mismatch. The dollar figure you typed doesn’t match what the bank’s system reads from the check. Double-check and re-enter it.
- Check is folded, torn, or damaged. Flatten it or bring it to a branch if it’s too damaged.
- Check not signed on the front. The person who wrote the check forgot to sign it. You’ll need to contact them for a new one.
- Illegible MICR line. If the printed numbers along the bottom of the check are smudged or altered, the system can’t process it electronically.
If your deposit is rejected, the funds won’t be deducted or credited, so you haven’t lost anything. Fix the issue and try again, or take the check to a branch or ATM as a backup.
Checks You Can’t Deposit by Phone
Most banks won’t accept certain types of checks through mobile deposit. These typically include money orders, third-party checks (checks made out to someone else who signed them over to you), foreign checks, and checks older than 180 days. Savings bonds and traveler’s checks are also off the table. If you try to deposit one of these, the app will reject it, and you’ll need to handle it in person.
