The main ways to deposit money into Discover checking
Discover Bank offers four primary deposit methods: direct deposit from your employer or other payers, transfers from another bank account you own, mobile check deposit through the Discover mobile app, and transfers from another Discover account if you have multiple accounts with them. You cannot deposit cash directly at a Discover branch because Discover operates as an online bank with no physical locations.
Each method has different timing and setup requirements. Direct deposit is the fastest and most hands-off once you set it up. Mobile check deposit works within hours for most checks. Bank transfers take one to three business days depending on the sending bank. Understanding which method fits your situation will save you time and prevent deposit delays.
Key Takeaways
- Direct deposit from your employer or government agency is the fastest deposit method and requires you to provide Discover's routing number and your account number to the payer.
- Mobile check deposit through the Discover app lets you photograph the front and back of a check, and funds typically appear within one business day.
- Transfers from another bank account you own take one to three business days and require you to link the external account through Discover's website or app.
- Discover does not accept cash deposits because it has no physical branches; you would need to deposit cash at your current bank first, then transfer the funds.
Setting up direct deposit to your Discover checking account
Direct deposit is the most reliable deposit method because it happens automatically on a set schedule. To set up direct deposit, you need Discover's routing number (021912915 for most Discover checking accounts) and your own account number, which appears on the bottom left of your checks or in the Account Details section of your online account.
Provide this information to your employer's payroll department or to any other organization sending you regular payments—Social Security, pension payments, tax refunds, or unemployment benefits. The payer will enter the routing and account numbers into their system, and deposits will arrive on your regular payment date. Most employers process direct deposit changes within one to two pay periods.
You can verify that direct deposit is working by checking your Discover account online or through the mobile app on the day you expect the deposit. If a deposit does not arrive within one business day of the expected date, contact Discover customer service to confirm the routing and account numbers were entered correctly.
Using mobile check deposit
Mobile check deposit lets you photograph a check using the Discover mobile app instead of visiting a bank branch. Open the app, navigate to the Deposit section, select Mobile Check Deposit, and photograph both the front and back of the check. The app will read the check amount and routing information automatically.
After you submit the deposit, Discover will send you a confirmation. Funds from mobile check deposits typically appear in your account within one business day, though Discover's terms state it may take up to two business days. Once the deposit posts, you should destroy the physical check by shredding it to prevent accidental duplicate deposits.
There are limits on mobile check deposit. Discover typically allows up to 100 deposits per month and limits individual checks to $2,500, though these limits can change. If you need to deposit a check larger than the limit, contact Discover customer service to discuss other options.
Transferring money from another bank account
You can move money from a checking or savings account at another bank into your Discover checking account. Log into your Discover account online or through the mobile app, go to the Transfer section, and select the option to transfer from an external bank account. Discover will ask for the routing number and account number of the account you want to transfer from.
The first time you link an external account, Discover may require verification. This typically involves Discover sending two small deposits (usually under $1 each) to that account within one to two business days. You will then need to log into the external bank account, find those deposit amounts, and enter them back into Discover to confirm you own the account. Once verified, future transfers from that account will not require this step.
Transfers from external accounts take one to three business days to complete. The exact timing depends on the other bank's processing speed. If you need funds faster, mobile check deposit or direct deposit are better options. Discover does not charge a fee for incoming transfers, but your other bank may charge a fee for outgoing transfers—check with them before initiating the transfer.
Transferring between your own Discover accounts
If you have multiple accounts with Discover—such as a savings account in addition to your checking account—you can transfer money between them when ready through your Discover account. Log in online or through the app, select Transfer, and choose the option to transfer between your Discover accounts. Funds move when ready and appear in both accounts right away.
This method is useful if you keep money in a Discover savings account and need to move it to checking for spending. There are no fees for transfers between your own Discover accounts, and the transfer completes the same day you initiate it.
What to do if you need to deposit cash
Discover does not accept cash deposits because it operates entirely online. If you have cash you need to deposit into your Discover checking account, you have two options: deposit the cash at your current bank (if you have one) and then transfer the funds to Discover, or visit a store that offers cash deposit services and ask them to deposit the cash into your Discover account.
Some retailers and third-party services allow you to deposit cash into a bank account for a fee, though this is less common than it once was. Your fastest option is usually to deposit cash at your current bank first, then use a bank transfer to move the funds to Discover within one to three business days.
Troubleshooting deposits that do not arrive on time
If a deposit you expected has not arrived, the first step is to confirm you used the correct information. For direct deposits, verify that your employer has the correct routing number (021912915) and account number. For mobile check deposits, check your app to confirm the deposit was successfully submitted—a confirmation message should appear after you photograph the check.
For transfers from another bank, check the sending bank's website to confirm the transfer was initiated from their end. Sometimes a transfer request fails silently if the account information was entered incorrectly. If the transfer shows as pending or failed in your external bank's system, you may need to initiate it again.
If you have confirmed the information is correct and the deposit still has not arrived after the expected timeframe, contact Discover customer service. Have your confirmation number (if applicable), the date you initiated the deposit, and the amount ready. Discover can investigate whether the deposit is stuck in processing or if there was an error on their end.
Frequently Asked Questions
Can I deposit cash at a Discover ATM?
No. Discover ATMs only allow withdrawals and balance inquiries. They do not accept cash deposits. If you need to deposit cash, you must use another method such as depositing at your current bank first and then transferring to Discover.
How long does a check deposit take through the mobile app?
Mobile check deposits typically post within one business day. Discover's terms allow up to two business days, so if your deposit has not appeared after two business days, contact customer service to confirm it was received.
What happens if I deposit the same check twice by accident?
Discover's system is designed to catch duplicate deposits, but it is not foolproof. If you accidentally deposit the same check twice, contact Discover when ready. They can reverse the duplicate deposit, though it may take a few business days to process.
Can I set up direct deposit from a government agency like Social Security?
Yes. Government agencies including Social Security, the IRS, and state unemployment offices all support direct deposit to Discover checking accounts. Provide them with Discover's routing number (021912915) and your account number, just as you would for employer direct deposit.
Is there a limit on how much I can transfer from another bank?
Discover does not publish a specific transfer limit, but most banks limit daily transfers to $10,000 or $25,000 depending on your account history and the sending bank's policies. If you need to transfer a larger amount, contact Discover to discuss options.
