The main ways to deposit money into Discover
Discover Bank offers three deposit methods: ACH transfers from another bank account, wire transfers, and mobile check deposit through their mobile app. Which one you use depends on where the money is coming from, how fast you need it to arrive, and what you have available to deposit.
ACH transfers are the most common route for moving money from a checking or savings account at another bank. Wire transfers work when you need the money to arrive the same business day or when you're receiving funds from outside the US. Mobile check deposit lets you photograph a paper check and deposit it without visiting a branch — Discover has no physical locations, so this is often the fastest option for check deposits.
Each method has different timing and requirements. Understanding which one fits your situation saves you from depositing money the slow way by accident.
Key Takeaways
- ACH transfers from another bank typically take one to three business days and are free, but require you to link an external account first through Discover's website or app.
- Mobile check deposit through the Discover app is usually the fastest way to deposit a paper check, often posting within one business day.
- Wire transfers arrive the same business day if sent before the cutoff time (usually 2 p.m. ET on weekdays), but cost money and require you to provide your wire details to the sender.
- You must verify any external bank account before you can transfer money from it, a process that takes a few days and involves Discover sending small test deposits.
Setting up ACH transfers from another bank
ACH is the standard way to move money between banks and is free. To start, log into your Discover account online or through the mobile app and look for "Transfer Money" or "Link Account" — the exact wording varies depending on which platform you're using.
You'll enter your external bank's routing number and your account number at that bank. Discover will then send two small deposits (usually under $1 each) to that account over the next few days. Once those deposits arrive, you log back into Discover, confirm the amounts, and the account is verified. Only then can you transfer money from it.
After verification is complete, you can initiate transfers whenever you want. The money typically arrives within one to three business days. Weekends and holidays don't count as business days, so a transfer you start on Friday afternoon won't land until Tuesday or Wednesday.
Depositing checks through the mobile app
Discover's mobile check deposit feature lets you photograph the front and back of a paper check and submit it through the app without mailing anything or visiting a location. Open the Discover mobile app, find "Deposit a Check" or "Mobile Deposit," and follow the prompts to photograph both sides.
The app will show you the amount it read from the check. Review it to make sure the number is correct, then submit. Discover will send you a confirmation, and the check usually posts to your account within one business day. Some checks clear faster — same-day posting is possible depending on when you submit and the check amount.
There are limits on how many checks you can deposit this way per day and per month. These limits vary, so check your account settings or contact Discover to confirm what applies to you. Once a check is submitted through mobile deposit, don't deposit it again through another method — that can cause problems with your account.
Wire transfers for same-day deposits
Wire transfers move money the same business day, but they cost money (Discover charges a fee for incoming wires) and require more information. To receive a wire, you need to provide the sender with your Discover account number, routing number, and full name as it appears on your account.
The sender initiates the wire from their bank, not from Discover. You can't start a wire transfer into Discover yourself — someone else has to send it to you. Wire transfers sent before 2 p.m. ET on a business day usually arrive the same day. Wires sent after that time or on weekends arrive the next business day.
Once the wire arrives, Discover will notify you and the money is available when ready. There's no verification period like there is with ACH transfers. If you're expecting a wire, make sure the sender has your correct account and routing numbers — wires can't be recalled once they're sent.
What information you need for each deposit method
| Deposit Method | Information Needed | Timing | Cost |
|---|---|---|---|
| ACH Transfer | Routing number and account number of the bank you're transferring from | 1–3 business days | Free |
| Mobile Check Deposit | The paper check itself | Usually 1 business day | Free |
| Wire Transfer | Your Discover account number, routing number, and full name | Same business day (if before 2 p.m. ET) | Fee charged by Discover |
Common reasons deposits don't arrive on time
ACH transfers sometimes take longer than expected because of how the banking system works. If you initiated a transfer on a Friday, it won't start processing until Monday. If the receiving bank (Discover) is experiencing technical issues, the transfer waits. If you entered the wrong routing or account number, the transfer bounces back to the sending bank, and you have to start over.
Check deposits can be delayed if the photo is blurry, if the check is damaged, or if the amount on the check doesn't match what you entered. Discover will notify you if there's a problem and ask you to resubmit. Very large checks sometimes require manual review, which adds a day or two.
Wire transfers are the most reliable for same-day arrival, but they fail if you provide incorrect account or routing information. Double-check these numbers before giving them to the sender — a wire sent to the wrong account is extremely difficult to recover.
Frequently Asked Questions
Can I deposit cash into Discover Bank?
No. Discover has no physical branches, so you cannot walk in with cash. You must convert cash to a check or transfer it from another bank account. If you have cash, deposit it into another bank account you own first, then transfer it to Discover using ACH.
How long does it take to verify an external bank account for ACH transfers?
Verification usually takes three to five business days. Discover sends two small test deposits to your external account, and you confirm the amounts once they arrive. Until you confirm, you cannot transfer money from that account.
What's the maximum amount I can deposit through mobile check deposit?
Limits vary by account and change over time. Check your Discover app settings or contact Discover directly to find out your current daily and monthly limits. Very large checks may require you to use a different deposit method.
If I send a wire transfer to Discover, do I need to do anything on my end?
No. The sender initiates the wire from their bank using your account and routing information. You just wait for it to arrive. Discover will notify you when the wire posts to your account.
Can I deposit money from a joint account at another bank?
Yes, as long as your name is on the account. Link the joint account using the routing number and account number, verify it the same way you would a personal account, and transfer money normally. Make sure your name matches exactly as it appears on the external account.
