The three ways to move money into Discover
You can deposit money into a Discover savings account through ACH transfer from another bank, wire transfer, or by mailing a check. Discover does not have physical branches or ATMs, so you cannot walk in or use a deposit envelope. The method you choose depends on how fast you need the money to arrive and whether you are moving funds from another bank account or receiving money from someone else.
ACH transfer is the slowest but most common route — it takes one to three business days and costs nothing. Wire transfer arrives the same day but carries a fee. Mailing a check works if you are not in a hurry and have a physical check to send.
Key Takeaways
- ACH transfer from another bank account is free and takes one to three business days to show up in your Discover account.
- Wire transfer arrives the same business day but Discover charges a fee to receive incoming wires.
- You can mail a physical check to Discover's address, though this method takes the longest — typically five to seven business days.
- Discover's website and mobile app both let you initiate ACH transfers yourself without calling customer service.
- If you are depositing a check by mail, write your Discover account number on the back and include a deposit slip if you have one.
ACH transfer: the free and standard method
An ACH transfer moves money electronically from your bank account to Discover using the automated clearing house network. This is the most common deposit method because it is free and works from any U.S. bank account. You initiate the transfer through your Discover account online or in the mobile app by linking your external bank account and entering the amount you want to move.
The transfer takes one to three business days to complete. Discover will ask you to verify the external account by depositing two small amounts (usually under $1 each) into it, then you enter those amounts back into Discover to confirm you own the account. This verification happens once per external account and protects against fraud. After verification, future transfers from that account are immediate to set up.
You can also initiate an ACH transfer from your other bank's website or app by adding Discover as an external account there. The timeline is the same — one to three business days — but you are controlling the transfer from the sending bank rather than from Discover.
Wire transfer: same-day arrival with a fee
A wire transfer moves money directly from your bank to Discover on the same business day. Discover charges a fee to receive incoming wires — check Discover's current fee schedule on their website, as wire fees vary and change. You initiate a wire through your current bank by providing Discover's routing number and your Discover account number as the receiving account.
Wire transfers are useful when you need money in your Discover account immediately — for example, if you are moving a large sum and want it settled before the market closes. The tradeoff is the fee your bank or Discover charges. Some banks also charge you to send a wire, so you may pay fees on both ends.
Contact Discover's customer service before sending a wire if you have questions about their routing number or account setup. Wires cannot be reversed once sent, so confirming the details beforehand prevents money from going to the wrong place.
Mailing a check to Discover
You can deposit a physical check by mailing it to Discover's processing address. Write your Discover account number on the back of the check in the endorsement area (where you normally sign). Include a deposit slip if you have one — Discover provides these when you open an account, or you can request one from customer service.
Mail the check to the address Discover provides on their website or in your account statements. Processing takes five to seven business days after Discover receives it, so the total time from mailing to deposit can be one to two weeks depending on postal delivery. This method works if you have a paper check and are not in a hurry.
Do not mail cash — use only checks or money orders. Discover will not be responsible for cash that is lost in the mail.
Linking an external bank account for ACH transfers
Before you can transfer money via ACH, you need to link the bank account you are transferring from. Log into your Discover account online or open the mobile app, then navigate to the transfer or deposit section. Select "Add External Account" or similar wording and enter your bank's routing number and your account number at that bank.
Discover will deposit two small test amounts into that account within one to two business days. Check your external bank account for these deposits — they will appear as small credits from Discover. Return to your Discover account and enter the exact amounts of those two deposits to verify you own the account. Once verified, you can transfer money freely between the accounts.
You can link multiple external accounts to your Discover savings account. Each account requires separate verification the first time, but after that you can move money between any of them without additional steps.
Timing and what to expect during the transfer
ACH transfers typically complete within one to three business days. The exact timeline depends on when you initiate the transfer and your other bank's processing schedule. If you start a transfer on a Friday evening, it may not begin processing until Monday, and then take one to three days from there. Weekends and bank holidays do not count as business days.
Once the transfer arrives in your Discover account, the money is available immediately — Discover does not hold deposits. You can withdraw or transfer the money out the same day it arrives. Wire transfers show up the same business day, usually within hours of being sent from your bank.
If a transfer does not arrive within the expected timeframe, contact Discover's customer service with the date you initiated it and the amount. They can trace the transfer through the ACH network or confirm whether your sending bank delayed it on their end.
What to do if a transfer fails or is rejected
An ACH transfer can fail if your external bank account number or routing number is incorrect, if you do not have enough funds in the sending account, or if your sending bank flags the transfer as suspicious. Discover will notify you if a transfer fails and usually explain the reason. Common reasons include "insufficient funds," "invalid account," or "account closed."
If the transfer failed due to incorrect account information, correct the details and try again. If it failed because of insufficient funds, add money to your sending account and initiate a new transfer. If your bank rejected it as suspicious, contact your bank to confirm the transfer is legitimate, then try again.
Wire transfers cannot be reversed once sent, but ACH transfers that fail are simply not processed — no money leaves your account. There is no fee for a failed ACH transfer.
Frequently Asked Questions
Can I deposit cash directly into Discover?
No. Discover has no physical locations or ATMs. You must convert cash to a check or money order, then mail it, or deposit the cash into another bank account first and transfer it to Discover via ACH or wire.
How long does it take to verify an external bank account?
Discover deposits two test amounts within one to two business days. You then enter those amounts back into Discover to verify. Once verified, the process is complete and you can transfer immediately. The entire verification usually takes two to three business days.
What is Discover's routing number for incoming transfers?
Discover's routing number is 011000015. Confirm this number on Discover's website or in your account before sending a wire or ACH transfer, as routing numbers can change.
Can someone else deposit money into my Discover account?
Yes. They can send you money via ACH transfer if they have your account number and routing number, or they can mail a check made out to you. Wire transfers require the sender to initiate from their own bank using your account details.
Is there a limit to how much I can deposit at once?
Discover does not publicly state a single-transfer limit, but very large transfers may trigger fraud reviews. Contact Discover before sending a wire or ACH transfer over $10,000 to confirm there are no holds or additional steps required.
