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

Discover Bank lets you close a checking account through three channels: calling 1-800-347-2000, logging into your online account and submitting a closure request, or mailing a written request to their address on file. The phone route is fastest — you can complete it in one call and confirm the account is closed the same day. Online closure through your account dashboard takes a few business days to process. Mailing a letter is slowest and requires you to keep proof of delivery.

Before you close, make sure your account balance is zero or positive. If you have a negative balance (overdraft), you must pay it off first — Discover will not close an account with money owed. You also need to stop any automatic payments or direct deposits linked to the account, or they will fail after closure. Check your recent statements for recurring charges and update them with a different payment method at least a week before you close.

Key Takeaways

  • Call Discover at 1-800-347-2000 to close your account over the phone, which is the fastest method and takes one business day.
  • Pay off any negative balance and cancel automatic payments or direct deposits before you close, or they will fail.
  • If you have a debit card linked to the account, it will stop working immediately after closure.
  • Discover does not charge a fee to close a checking account at any time.
  • Keep your account number and confirmation details for your records in case a payment bounces after closure.

What happens to your debit card and pending transactions

Your Discover debit card becomes inactive as soon as the account closes. If you have pending transactions — charges that posted but have not cleared yet — they will still process against the account for a few days after closure. Discover holds the account open long enough to clear these transactions, then closes it. This means you may see activity on a closed account for up to five business days.

If a transaction tries to process after the account is fully closed and there are no funds, it will be declined. Recurring charges like subscriptions or gym memberships will fail, so update those accounts first. Any refunds or credits that were supposed to go to this account will bounce back to the merchant, and you will need to contact them to reroute the money to a different account.

How to handle direct deposits and automatic payments

Stop all automatic bill payments at least one week before you close. Log into each biller's website (your credit card company, utility, insurance, loan servicer) and change the payment method to a different bank account or credit card. Do not rely on the closure to stop them — some billers may retry failed payments multiple times, and you could face overdraft fees or late payment marks.

If you receive direct deposits (paycheck, benefits, tax refunds), update your employer or the paying agency with your new bank account number before you close. Paychecks that deposit to a closed account will be rejected, and your employer may hold the funds while they wait for you to provide a corrected account number. This can delay your pay by one or two pay cycles. Contact your HR department or the benefits office at least two weeks ahead if possible.

Closing your account by phone

Call Discover customer service at 1-800-347-2000 during business hours (Monday through Friday, 8 a.m. to 11 p.m. Eastern; Saturday and Sunday, 9 a.m. to 11 p.m. Eastern). Have your account number and a government-issued ID ready. The representative will verify your identity, confirm your account balance is zero or positive, and ask why you are closing. You do not have to answer the reason question, but Discover may ask.

The representative will process the closure and give you a confirmation number. Write down this number and the date and time of the call. The account will close by the end of that business day. Ask the representative for the mailing address where you can send any remaining checks or to confirm there are no outstanding transactions. Keep the confirmation number for at least 60 days in case a payment bounces and you need proof the account was closed.

Closing your account online

Log into your Discover online banking account and look for a "Close Account" or "Account Settings" option, usually found under Account Management or Help & Support. Click through to the closure request form. You will need to confirm your account balance is zero and that you have stopped automatic payments. Discover will ask you to review the closure terms and click a final confirmation button.

Online closure takes three to five business days to complete. Discover will send you a confirmation email once the account is closed. Check your email (including spam and promotions folders) for this confirmation. If you do not receive an email within five business days, call customer service to confirm the closure went through. Save the confirmation email or take a screenshot for your records.

Closing your account by mail

Write a letter to Discover requesting closure of your checking account. Include your full name, account number, the date, and a simple statement: "I request closure of my Discover checking account [account number] effective immediately." Sign the letter and mail it to the address listed on the back of your Discover debit card or on your monthly statement. Send it via certified mail with return receipt requested so you have proof Discover received it.

Mail closure takes 7 to 14 business days from the date Discover receives your letter. Keep the certified mail receipt and the return receipt card. Discover will send you a written confirmation of closure to your mailing address on file. If you do not receive confirmation within three weeks, call customer service with your certified mail tracking number to confirm the closure was processed.

What to do if the account has a negative balance

If your account is overdrawn (negative balance), you must deposit funds to bring it to zero before Discover will close it. You can transfer money from another bank account using Discover's online transfer tool, deposit a check through mobile deposit, or visit an ATM that accepts Discover deposits. Once the balance is positive or zero, you can proceed with closure through any of the three methods above.

If you ignore the negative balance and try to close anyway, Discover will deny the closure request and may send the debt to a collection agency if it remains unpaid for 60 days. This will damage your credit score. If you cannot pay the full amount, contact Discover customer service to ask about a payment plan before you close the account.

Frequently Asked Questions

Does Discover charge a fee to close my checking account?

No. Discover does not charge any fee to close a checking account at any time, whether you close it immediately after opening or after years of use. There are no early closure penalties or account closure fees.

What if I close my account and then a check I wrote bounces?

Checks written against a closed account will be returned unpaid. The person or business you wrote the check to will see it marked "Account Closed." Contact them immediately to arrange payment by another method. You may face a returned check fee from the recipient, though Discover will not charge you one.

Can I reopen a Discover checking account after I close it?

Yes, you can open a new Discover checking account at any time. However, if you closed the account due to a negative balance or fraud dispute, Discover may review your history before approving a new account. There is no waiting period, but the approval process may take one to three business days.

What happens to my account number after I close?

Your old account number becomes inactive and cannot be reused. If you open a new Discover checking account later, you will receive a different account number. Do not give your old account number to anyone after closure, as it will not work for deposits or payments.

How long does it take to receive a refund if I had a credit balance?

If your account had a positive balance when you closed it, Discover will mail a check to your address on file within 7 to 10 business days. Make sure your mailing address is current before you close. If you do not receive the check within two weeks, call customer service with your account closure confirmation number.
