Call Discover's customer service line to request cancellation
The fastest way to cancel a Discover card is to call Discover directly. Their customer service team handles cancellations over the phone and can process your request immediately. You can reach them at the number on the back of your card, or find it on your Discover account online.
When you call, have your card number ready. Tell the representative you want to close the account. They may ask why you're canceling — this is optional information, and you don't have to give a reason. Some representatives may offer you a retention offer (like a higher cash back rate for a limited time) to keep the account open. You can accept or decline.
After you confirm the cancellation, ask the representative for a confirmation number and the date the account will close. Write this down. The account typically closes within a few business days, though Discover may take up to 30 days to fully process the closure.
Key Takeaways
- Call the number on the back of your Discover card to cancel; the process takes about five minutes and closes the account within a few business days.
- Pay off any remaining balance before or during the call, since closing an account with an unpaid balance can damage your credit score.
- Request a confirmation number and closing date so you have proof of when the account was closed.
- Check your credit report 30 to 60 days after closure to confirm the account shows as closed, not delinquent.
- Discover may offer you a retention bonus to keep the account open — you can accept or refuse without penalty.
Pay off your balance before closing
Do not cancel a Discover card with an outstanding balance. If you close the account while you still owe money, Discover will continue to charge interest on that balance, and the account will show as delinquent on your credit report if you miss a payment.
Pay the full balance before you call to cancel, or ask the representative to process the cancellation after you've made a payment that brings the balance to zero. If you need time to pay off the balance, wait until you've done so before requesting closure. Closing the account does not erase what you owe — it only stops you from using the card.
Stop using the card immediately
Once you've called and requested cancellation, do not use the card for new purchases. Discover may decline transactions after you've requested closure, or the charge may go through and then be reversed, creating confusion with merchants.
If you have recurring charges set to that card (subscriptions, automatic bill payments, insurance premiums), update those to a different payment method before you cancel. Discover will not process charges after the account closes, and missed payments on those bills can hurt your credit score or result in service interruptions.
Verify the closure on your credit report
After 30 to 60 days, check your credit report to confirm that Discover shows the account as closed. You can view your credit report for free once per year at annualcreditreport.com, which is the official site run by the three major credit bureaus (Equifax, Experian, and TransUnion).
Look for the Discover account and verify that the status says "closed" or "closed by consumer." If it shows as delinquent, past due, or still open, contact Discover immediately with your confirmation number and ask them to correct it. Errors on your credit report can lower your credit score and affect your ability to get loans or credit cards in the future.
Understand how cancellation affects your credit score
Closing a credit card can temporarily lower your credit score, usually by 5 to 10 points, because it reduces your total available credit. If you had a $5,000 limit on the Discover card and $20,000 in total limits across all your cards, closing it drops your total available credit to $15,000. This changes your credit utilization ratio — the percentage of your available credit that you're actually using.
The impact is temporary. Your score typically recovers within a few months as long as you continue paying other bills on time and keep your credit utilization low on remaining cards. If you're planning to apply for a mortgage, car loan, or another major credit product within the next few months, consider waiting to cancel until after the application is approved.
What to do if you can't reach Discover by phone
If you prefer not to call or cannot reach customer service, you can request cancellation through your Discover online account. Log in, go to your account settings, and look for a "close account" or "cancel card" option. Not all account types offer this online, so you may still need to call.
You can also send a written request by mail. Write a letter to Discover stating that you want to close your account, include your card number and account number, and send it to the address on your statement or billing insert. Keep a copy for your records. Mail takes longer than a phone call — allow two to three weeks for processing — so use this method only if you're not in a hurry.
Frequently Asked Questions
Will Discover charge me a cancellation fee?
No. Discover does not charge a fee to close a credit card account. If a representative mentions a fee, ask to speak with a supervisor — this is not a standard Discover practice. You should never pay money to cancel a credit card.
Can I reopen my Discover card after I cancel it?
Discover may allow you to reopen a closed account within a certain window, usually 30 to 60 days. Contact Discover customer service to ask if your specific account can be reopened. After that window closes, you would need to apply for a new card, which is treated as a new account and will trigger a hard inquiry on your credit report.
What happens to my Discover cash back rewards if I cancel?
Any cash back balance you've earned remains yours. Before you cancel, log into your Discover account and redeem your rewards — you can usually transfer them to a bank account or use them as a statement credit. After the account closes, you typically have 90 days to redeem remaining rewards, though this varies. Check your account terms or call to confirm the deadline.
Do I need to destroy my physical Discover card after canceling?
Yes. Cut the card in half or shred it so it cannot be used. Even though the account is closed, a physical card in circulation is a security risk. Discover will not send you a new card after closure, but destroying the old one prevents accidental or fraudulent use.
How long does it take for Discover to fully close my account?
Discover typically closes the account within a few business days of your request, though the full closure can take up to 30 days. The representative will give you a specific date when you call. After that date, the account will no longer appear as active on your credit report, though it may show as "closed" for up to seven years.
