The main ways to deposit money into Discover checking

Discover Bank offers three deposit methods for checking accounts: mobile check deposit through the Discover mobile app, ACH transfers from another bank account you own, and wire transfers from another financial institution. Mobile check deposit is the fastest for most people—you photograph the front and back of a check and submit it through the app. ACH transfers take one to two business days but cost nothing. Wire transfers arrive the same day but carry a fee and require you to provide Discover's wire instructions to the sending bank.

Discover does not accept cash deposits at physical locations because it operates as an online-only bank with no branch network. You cannot walk into a Discover office and hand over cash. If you need to deposit cash, you must first move it to another bank account you control, then transfer it to Discover using ACH or a wire.

Key Takeaways

  • Mobile check deposit through the Discover app is the fastest method for most deposits and requires only your phone and the check.
  • ACH transfers from another bank account take one to two business days and carry no fee, making them the cheapest option for regular deposits.
  • Wire transfers arrive the same day but cost money and require you to initiate the transfer from the sending bank, not from Discover.
  • Discover does not accept cash deposits because it has no physical branches; convert cash to a check or move it through another bank first.
  • Check deposits have daily and monthly limits that vary by account age and history; the app will tell you your limit when you attempt a deposit.

Mobile check deposit through the Discover app

To deposit a check using your phone, open the Discover mobile app, navigate to the deposit or transfer section, and select "Mobile Check Deposit." Photograph the front of the check, then the back, making sure the entire check is visible and the image is clear. The app will show you what it read from the check—the routing number, account number, check number, and amount. Verify these details match the physical check. If anything is wrong, retake the photo.

Once you submit the deposit, Discover will hold the funds for one business day before they become available in your account. This hold is standard across the banking industry. After the hold period ends, the money is yours to spend. Discover will destroy the physical check after processing, so keep it in a safe place until the deposit clears in case you need proof of the transaction.

Check deposits through the mobile app have limits. New accounts typically start with a lower daily limit—often $2,500 per day—and a monthly limit of $5,000 to $10,000. As your account ages and you build a history with Discover, these limits increase. The app will show you your current limit before you submit a deposit, so you will know whether a particular check can go through.

ACH transfers from another bank account

An ACH transfer is an electronic movement of money from one bank to another. To set one up, log into your Discover account online or through the app, go to the transfer section, and select "Transfer from another bank." Discover will ask you to enter the routing number and account number of the bank you want to transfer from. You can find these numbers on a check from that account or by logging into that bank's website.

After you enter the account details, Discover will send two small test deposits—usually between $0.01 and $0.99—to that account. This is a security step called microdeposit verification. You will need to log into the other bank's account, find those two deposits, and tell Discover what the amounts were. Once you verify them, the account is linked and you can transfer money whenever you want.

ACH transfers take one to two business days to complete. If you initiate a transfer on a Monday morning, the money will land in your Discover account by Wednesday. Transfers initiated on weekends or after business hours are processed the next business day. There is no fee for ACH transfers, making them the cheapest way to move money into Discover. You can set up recurring transfers if you want money to move automatically on a schedule—for example, every payday.

Wire transfers for same-day deposits

A wire transfer moves money from another bank to Discover on the same business day. To send a wire, you initiate the transfer from the other bank, not from Discover. Log into that bank's website or call their wire department and tell them you want to send a wire to Discover Bank. They will ask for Discover's wire routing number, your Discover account number, and the amount you want to send.

Discover's wire routing number is different from its ACH routing number. You can find the correct wire routing number by logging into your Discover account, going to the transfer section, and looking for "Wire Transfer Instructions" or by calling Discover customer service. Write down the exact number before you contact the other bank, because using the wrong routing number will send your money to the wrong place.

Wire transfers typically cost $15 to $25 at the sending bank, though some banks charge more. The fee comes out of your account at the sending bank, not from Discover. Money sent by wire before 2 p.m. Eastern Time on a business day usually arrives in your Discover account the same day. Wires sent after 2 p.m. or on weekends are processed the next business day.

What to do if you need to deposit cash

Discover cannot accept cash directly because it has no physical locations. If you have cash and need to get it into your Discover account, you have two options: deposit the cash at another bank you use, then transfer it to Discover via ACH, or exchange the cash for a check at your bank and deposit that check through the Discover mobile app.

The first option is simpler if you have another bank account. Deposit your cash there, wait for it to clear (usually one business day), then set up an ACH transfer from that account to Discover. The second option works if you do not have another account—go to your bank, ask them to issue a cashier's check for the amount you want to deposit, then photograph that check in the Discover app.

Deposit limits and holds

Discover places limits on how much you can deposit through mobile check deposit. These limits depend on your account age, deposit history, and whether you have had any problems with previous deposits. A brand-new account might have a $2,500 daily limit and a $5,000 monthly limit. An account that has been open for a year with a clean history might have a $10,000 daily limit and a $25,000 monthly limit. Discover does not publish exact limits publicly because they vary by account.

When you attempt a mobile check deposit, the app will show you how much you can deposit that day and how much room you have left in your monthly limit. If a check exceeds your limit, you can deposit it later in the month or use a wire transfer instead. ACH transfers and wire transfers do not have the same deposit limits as mobile check deposits, though your Discover account may have an overall daily transfer limit of $100,000 or more depending on your account type.

All deposits are subject to a hold. Mobile check deposits are held for one business day. ACH transfers are held for one to two business days. Wire transfers typically clear immediately or within a few hours. During the hold period, the money is in your account but you cannot spend it. After the hold lifts, the funds are fully available.

Troubleshooting common deposit problems

If a mobile check deposit is rejected, the app will tell you why. Common reasons include poor image quality, a check that is too old (more than six months), a check with a missing signature, or a check that has already been deposited. Retake the photo in good lighting and make sure the entire check is visible. If the check is old or already deposited, you will need to use a different check or contact the check issuer for a replacement.

If an ACH transfer does not arrive after two business days, log into your Discover account and check the transfer status. The transfer may still be processing, or it may have been rejected if you entered the wrong routing or account number. If it was rejected, Discover will show you the reason. Contact the sending bank to confirm the account details are correct, then initiate a new transfer. If a wire transfer does not arrive, contact Discover customer service immediately with the wire confirmation number from the sending bank—wires can be traced and recovered if they went to the wrong place.

Frequently Asked Questions

Can I deposit a check written to someone else?

No. The check must be made out to you or to you and another person whose name is on the Discover account. If a check is made out to someone else, that person must deposit it into their own account. Depositing a check made out to another person is considered check fraud.

How long does it take for money to show up after I deposit a check?

The money appears in your account within one business day, but it is held and you cannot spend it during that time. After the hold lifts—usually one business day—the funds are fully available. In total, most check deposits clear within one to two business days from the time you submit them through the app.

What if I deposit the same check twice by accident?

Discover's system is designed to catch duplicate deposits. If you submit the same check twice, the second deposit will be rejected and you will see an error message in the app. If somehow a duplicate deposit goes through, contact Discover customer service and they will reverse the duplicate deposit and return the money.

Can I deposit a check that is post-dated?

Technically yes, but Discover may reject it. A post-dated check is one with a date in the future. Banks are not required to honor post-dated checks, and Discover's system may flag it as invalid. If you have a post-dated check, wait until the date on the check arrives before you deposit it.

Is there a fee for depositing money into Discover checking?

No. Mobile check deposits, ACH transfers, and wire transfers initiated by the sending bank are all free at Discover. Wire transfers do carry a fee, but that fee is charged by the bank sending the wire, not by Discover. Some banks charge $15 to $25 to send a wire on your behalf.
