Discover does not accept check deposits through the mail or at physical locations
Discover Bank has no branches and does not process paper checks sent by mail. You cannot walk into a location to deposit a check, and you cannot mail a check to Discover for deposit. If you have a check you need to deposit into a Discover savings account, you will need to use one of three routes: mobile check deposit through the Discover app, transfer the funds from another bank account you control, or cash the check elsewhere and transfer the money electronically.
The fastest and most direct method is mobile check deposit if you have the Discover mobile app. This feature lets you photograph the front and back of a check and submit it through your phone. The funds typically appear in your account within one business day, though Discover may hold the deposit for up to five business days depending on the check amount and your account history.
Key Takeaways
- Mobile check deposit through the Discover app is the only way to deposit a check directly into your Discover account without visiting another bank.
- You will need the Discover mobile app installed on your phone and a valid camera to photograph both sides of the check.
- Funds from mobile check deposits typically post within one business day, but Discover may hold larger deposits for up to five business days.
- If you do not have the app or prefer not to use it, you can deposit the check at your current bank and transfer the funds to Discover electronically.
How to use mobile check deposit on the Discover app
Open the Discover mobile app and log in with your username and password. Navigate to the menu or account section and look for "Mobile Check Deposit" or "Deposit a Check." You will be asked to select which account to deposit into — choose your savings account. The app will then prompt you to photograph the front of the check, followed by the back. Make sure the entire check is visible in the frame, the image is in focus, and the lighting is clear enough to read the numbers and text.
After you submit both images, the app will show you the check amount and ask you to confirm the deposit. Review the amount carefully — if it is wrong, you can cancel and retake the photos. Once you confirm, the check is submitted for processing. Discover will send you a notification when the deposit has been received and again when the funds post to your account. Do not spend or discard the original check until the deposit has fully cleared, which typically takes one to five business days.
What happens if mobile check deposit is not available to you
Mobile check deposit may not be available if your account is very new, if you have had fraud or disputes on your account, or if Discover has placed a temporary hold on check deposits for your account. If the feature is greyed out or missing from your app, contact Discover customer service to ask whether the restriction is temporary and when it might be lifted.
If you cannot use mobile deposit, the alternative is to deposit the check at a bank or credit union where you have an account, then transfer the funds electronically to your Discover savings account. This takes longer — typically two to three business days for the transfer to complete — but it works if you have access to another financial institution. You can also cash the check at the issuing bank (the bank name printed on the check) or at a check-cashing service, then transfer the cash electronically or deposit it into Discover through a linked account at another bank.
Deposit limits and holds on check deposits
Discover does not publish a single daily or monthly limit for mobile check deposits, but the bank may decline deposits that are unusually large for your account or that exceed certain thresholds. If your deposit is rejected, the app will tell you why. Checks for more than $10,000 may trigger additional review or reporting requirements under federal law, which can extend the hold period.
Discover typically holds mobile check deposits for one business day before the funds become available, but the bank reserves the right to hold funds for up to five business days. Longer holds are more common for checks over $5,000, checks from accounts outside the United States, or if you are a new customer. The hold does not mean the check has not cleared — it means Discover is verifying the check is legitimate before releasing the funds to you.
What to do if a check deposit fails or is rejected
If you submit a check through mobile deposit and receive an error message, the most common reasons are poor image quality, the check is already deposited, the check is post-dated (dated in the future), or the check amount is illegible. Retake the photos in better lighting and make sure the entire check is in frame. If the same check keeps failing, try depositing it through another method — at your current bank or through a check-cashing service.
If Discover rejects the deposit outright, the bank will notify you of the reason. Common rejection reasons include the check being stale-dated (more than six months old), the check being damaged or altered, or the check being flagged as fraudulent or already deposited elsewhere. Contact the person or business who issued the check to ask for a replacement, or ask them to send the funds by another method such as ACH transfer or wire.
Endorsing the check before deposit
Before you photograph the check for mobile deposit, sign the back of the check in the endorsement area — the blank space on the back, usually near the top. Write your signature on the line provided. Some banks ask you to write "For mobile deposit only" below your signature, though Discover does not require this. Do not sign the check until you are ready to deposit it, because a signed check can be cashed by anyone who has it.
After the deposit has posted to your account and cleared (usually within five business days), you can destroy the original check by shredding it or tearing it up. Keep it until then in case Discover needs to verify the deposit or in case the check bounces and needs to be resubmitted.
Transferring funds from another bank instead of depositing a check
If you have a checking account at another bank and the check is drawn on that same bank, you can deposit the check there first, then transfer the funds to your Discover savings account electronically. This avoids the mobile deposit process entirely and may be faster if you are already at that bank's location or ATM.
To transfer funds from another bank to Discover, log into your Discover account online or through the app and look for "Transfer Money" or "Link an Account." You will need the routing number and account number of the other bank. Discover will verify the account by depositing two small amounts (usually under $1 each) and asking you to confirm those amounts. Once verified, you can transfer money between the accounts. Transfers typically take one to three business days, depending on the other bank's processing speed.
Frequently Asked Questions
Can I deposit a check at a Discover ATM?
No. Discover ATMs only dispense cash and do not accept check deposits. You must use the mobile app to deposit checks into a Discover account.
What if the check is made out to someone else?
You cannot deposit a check made out to another person into your own account. The check must be made payable to you or to you and another person jointly. If the check is made out to someone else, that person must deposit it into their own account, or they must sign the back and write "Pay to the order of [your name]" if the bank allows third-party deposits.
How long does it take for a mobile check deposit to show up?
The funds usually appear in your account within one business day. Discover may hold the deposit for up to five business days before the funds are fully available for withdrawal, depending on the check amount and your account history.
What if I accidentally deposit the same check twice?
Discover's system is designed to catch duplicate deposits, but if a check is deposited twice, you will be notified and asked to return the duplicate funds. Contact Discover customer service when ready if you realize you have submitted the same check more than once.
Can I deposit a check if I do not have the Discover app?
You cannot deposit a check directly without the app, but you can deposit the check at another bank you use and transfer the funds to Discover electronically. You will need the routing and account number of your Discover savings account to set up the transfer.
