You can close a Discover Bank account by phone, online, or by mail — the fastest way is a phone call to their customer service line

Closing a Discover Bank account takes about 15 minutes if you call, or a few days if you do it online or by mail. Before you close, make sure any pending transactions have cleared, move your money out, and set up direct deposit elsewhere if you receive paychecks. Discover will not charge you a fee to close, and you do not need a reason to do it.

The account closes once all transactions settle and your balance reaches zero. If you have a negative balance (meaning you owe money), you must pay that before the account will fully close. After closure, you can no longer use the debit card or access the account online.

Key Takeaways

  • Call Discover Bank customer service at 1-800-347-2000 to close your account over the phone, which is the fastest method.
  • Wait for all pending transactions to clear and transfer your remaining balance to another bank account before closing.
  • If you receive direct deposit paychecks, update your employer or payroll system with your new bank details before closing.
  • Closing takes effect once your balance is zero and all transactions have settled, which usually happens within a few business days.
  • You can also close by logging into your online account or mailing a written request, though these methods take longer than calling.

Closing by phone is the fastest option

Call Discover Bank customer service at 1-800-347-2000. Have your account number ready. Tell the representative you want to close your account. They will ask you why (you do not have to give a detailed reason — "I'm moving my banking elsewhere" is enough), confirm your identity, and process the closure request.

The representative will tell you when the account will be fully closed. This usually happens within 3 to 5 business days after you call, once all pending transactions clear and your balance reaches zero. If you have money in the account, they may ask whether you want it mailed to you or transferred to another bank account — transferring is faster and safer.

Prepare your account before closing

Before you call or submit a closure request, transfer any remaining money out of the account. Log into your Discover Bank online account and use the transfer tool to move funds to another bank account you own, or request a check be mailed to you. Transfers to another bank usually take 1 to 3 business days.

Check your recent transactions to make sure nothing is still pending. If you have automatic payments set up (like insurance, subscriptions, or loan payments), update those to pull from your new bank account instead. If you receive direct deposit paychecks, contact your employer's payroll department or HR and give them your new bank account details so your next paycheck goes to the right place.

If you have a Discover debit card linked to the account, you will no longer be able to use it after closure. Destroy the card by cutting it up, or wait for it to expire naturally.

Closing online through your account

Log into your Discover Bank account online. Go to Settings or Account Management (the exact location varies, but look for a link about account settings or preferences). Look for an option to close your account or manage your account status. Click it and follow the prompts to confirm closure.

Online closure requests usually take 5 to 7 business days to process, longer than calling. You will receive a confirmation email once the request is submitted. The account will close once your balance is zero and all transactions have cleared.

Closing by mail

Write a letter to Discover Bank requesting account closure. Include your full name, account number, and the date. Keep the letter brief — one or two sentences is enough. Mail it to Discover Bank's mailing address, which you can find on the back of your debit card or on their website under "Contact Us."

Closure by mail takes the longest — usually 7 to 10 business days or more, depending on mail delivery time and processing. Send the letter via certified mail if you want proof it was received. Make sure your account balance is zero before mailing, or transfer any remaining funds separately.

What happens after your account closes

Once closed, you cannot use your Discover debit card or log into the account online. Any pending transactions that were in progress when you closed will still process, so your account may show activity for a few days after closure. If a transaction posts after closure and creates a negative balance, Discover will contact you about payment.

Discover keeps records of closed accounts for a set period. If you ever need to reference old transactions or statements, you can contact customer service and request them. Your account closure will not affect your credit score — closing a bank account is different from closing a credit card.

If you have a negative balance

If you owe money on your Discover Bank account (a negative balance), you must pay it before the account will close. This can happen if a transaction posts after you think your balance is zero, or if you have an overdraft fee. Call customer service to find out the exact amount owed, then pay it by debit card, bank transfer, or check.

Once you pay the negative balance and it clears, your account balance will be zero and closure can proceed. If you do not pay, Discover may send your account to collections, which can affect your credit and result in legal action.

Frequently Asked Questions

Will closing my Discover Bank account hurt my credit?

No. Closing a bank account does not affect your credit score. Your credit is based on borrowing and repayment history (credit cards, loans, payment history), not on which bank you use for checking or savings.

Can I reopen my account after closing it?

Once closed, you cannot reopen the same account. If you change your mind, you would need to open a new Discover Bank account, which takes a few minutes online or by phone. There is no fee to open a new account.

What if I still have pending transactions when I close?

Pending transactions will still process after you close. Make sure your account has enough balance to cover them, or they may overdraft. Wait a few days for pending items to clear before closing, or call customer service to ask about specific transactions.

Do I need to destroy my debit card?

You should destroy your card by cutting it up or shredding it so it cannot be used. You can also ask Discover to deactivate it when you close the account. Do not throw an intact card in the trash.

How long does it take to get my money back if I request a check?

If you ask Discover to mail a check for your remaining balance, it usually takes 5 to 10 business days to arrive, depending on mail delivery. Requesting a transfer to another bank account is faster — usually 1 to 3 business days.
