The basic steps for mobile check deposit
Most banks and credit unions let you deposit a check by taking photos of the front and back with your phone, then submitting them through their mobile app. You do not need to visit a branch or ATM. The process usually takes less than two minutes, and the funds typically appear in your account within one to three business days.
The bank's app handles the photos and sends them to their processing system. You will need your account number and routing number, which you can find on a check or in your online banking profile. Some banks require you to sign the back of the check before photographing it; others do not. Check your bank's specific rules before you start.
Not every bank offers mobile check deposit, and some limit how many checks you can deposit per day or per month. Call your bank or log into your app to confirm the feature is available on your account.
Key Takeaways
- Mobile check deposit requires your bank's app, two clear photos (front and back), and an internet connection, but no visit to a branch.
- Funds from mobile deposits typically post within one to three business days, not immediately.
- You must endorse (sign) the back of the check before photographing it if your bank requires it; some banks do not.
- Daily and monthly deposit limits vary by bank, so check your app or call customer service to confirm your limits.
- After the bank processes your deposit, you should destroy the physical check or write "VOID" across it to prevent accidental double deposits.
How to take photos that the bank will accept
The bank's app will guide you through the photo process, but the images must meet specific standards or the deposit will be rejected. Both the front and back of the check must be fully visible, in focus, and properly lit. Shadows, glare, and cropped edges are common reasons deposits fail.
Place the check on a flat, light-colored surface and hold your phone directly above it, not at an angle. Use natural light or a lamp to avoid shadows. Make sure all four corners of the check are visible in the frame. The app will usually show you a preview before you submit, so review both images carefully before confirming.
If the app rejects your photos, it will tell you why — usually "image too dark," "check not fully visible," or "text not readable." Take new photos with better lighting or a steadier hand, and try again. Most banks allow unlimited resubmission attempts.
What happens after you submit the photos
Once you hit submit, the app will confirm receipt and give you a reference number. The bank's system scans the images, reads the check amount and routing information, and flags any problems — a missing signature, an illegible amount, or a check that appears to be a duplicate.
If everything looks correct, the deposit is processed and your account balance updates within one to three business days. Some banks show the deposit as "pending" immediately and then clear it after processing. Others do not show it until it clears. Log into your app or online banking to track the status.
If the bank cannot read the check or spots a problem, it will send you a message through the app or by email asking you to resubmit or contact customer service. Do not ignore these messages — the deposit will not go through until you resolve the issue.
Signing the back of the check
The back of a check has a blank line where you sign your name. This is called endorsing the check. Some banks require you to sign before photographing; others do not. A few banks ask you to sign, then write "For mobile deposit only" below your signature.
Check your bank's app or website for their endorsement rules. If you are unsure, sign the check before taking the photo — this covers you either way. Use a pen, not a pencil, and sign clearly. Do not sign the front of the check.
After the bank processes the deposit, write "VOID" across the front and back of the check in large letters. This prevents you or anyone else from accidentally depositing it again at an ATM or branch.
Daily and monthly deposit limits
Banks set limits on how much you can deposit through mobile check deposit in a single day and over a rolling month. These limits vary widely. Some banks allow $5,000 per day and $25,000 per month; others allow $10,000 per day and $50,000 per month. A few have no stated limit.
You can find your limits in the mobile app — usually under settings or account details — or by calling customer service. If you hit your daily limit, you can deposit again the next day. If you hit your monthly limit, you will have to wait until the rolling month resets, which is usually 30 days from your first deposit.
If you regularly deposit checks larger than your limit, ask your bank whether you can request a higher limit or whether you need to use a branch or ATM for large checks instead.
Troubleshooting common problems
The most common reason a mobile deposit fails is poor image quality — blurry photos, shadows, or missing corners. Retake the photos in better light and make sure the entire check is visible. The second most common reason is a missing or illegible signature on the back. Sign the check clearly before photographing.
If the app says the check has already been deposited, you may have submitted it twice by accident, or the check may have been deposited at a branch or ATM before you tried mobile deposit. Contact customer service with your reference number and they can investigate.
If the app crashes or you lose your internet connection after taking photos but before submitting, the photos are usually saved in the app. Open it again and look for a draft deposit or a resume option. If the deposit was submitted but you did not see a confirmation, check your account history or call customer service to confirm it went through.
What to do with the physical check after deposit
Once the bank has processed your mobile deposit, the physical check is no longer needed. Write "VOID" in large letters across the front and back to make it unusable. Do not throw it away immediately — keep it for at least 30 days in case the bank needs to verify the deposit or in case a problem arises.
After 30 days, you can safely destroy the check by shredding it or tearing it up. Do not deposit the same check again at an ATM, a branch, or through another bank's app. Depositing the same check twice is considered check fraud, even if it was an accident, and can result in overdraft fees, account closure, or legal action.
Frequently Asked Questions
How long does it take for the money to show up in my account?
Most banks post mobile check deposits within one to three business days. Some show the deposit as pending immediately, while others do not show it until it clears. Weekends and holidays do not count as business days, so a check deposited on Friday may not clear until Tuesday or Wednesday.
Can I deposit a check that someone else wrote to me?
Yes, as long as the check is made out to you or to you and someone else. You must sign the back of the check (endorse it) before photographing. If the check is made out to someone else, you cannot deposit it through mobile deposit — they must deposit it themselves or sign it over to you in writing, which varies by state.
What if the check amount is illegible in the photo?
The bank will reject the deposit and ask you to resubmit. Retake the photo with better lighting so the amount is clearly readable. If the check itself is damaged or faded, you may need to contact the person who wrote it and ask for a replacement check.
Can I deposit a check that is post-dated or already past due?
Most banks will process a post-dated check (one dated in the future) through mobile deposit, though the funds may not clear until that date. A check that is more than six months old is considered stale-dated and banks are not required to process it. Contact your bank if you are unsure whether a check is too old.
What if I accidentally deposit the same check twice?
Contact your bank immediately. If you catch it before the second deposit clears, the bank can usually reverse it. If both deposits have cleared, the bank will investigate and remove the duplicate. Repeated double deposits can result in account closure, so mark checks "VOID" as soon as they are processed to prevent this.
