Call Discover's customer service line to request cancellation

The fastest way to cancel a Discover card is to call Discover directly at 1-800-347-2683. A representative will walk you through the cancellation process over the phone. Have your card number ready when you call, and be prepared to answer security questions to confirm your identity.

Discover will ask why you're canceling — this is standard practice and doesn't affect whether they'll close the account. They may offer you incentives to keep the card open, such as a reduced interest rate or waived annual fee. You can accept or decline these offers. Once you confirm you want to cancel, the representative will process the closure immediately.

After the call ends, Discover will send you a written confirmation in the mail within 7 to 10 business days. Keep this confirmation letter for your records. The account closure date will be listed on it.

Key Takeaways

  • Call 1-800-347-2683 to cancel; the process takes about 10 minutes and closes the account the same day.
  • Pay off any remaining balance before you call, or arrange a payment plan if you cannot pay it all at once.
  • Discover will mail a written confirmation within 7 to 10 business days; save this letter as proof of cancellation.
  • After cancellation, your credit report will show the account as closed, which may temporarily lower your credit score.
  • If you have pending transactions or rewards points, settle those before calling to cancel.

What to do before you call

Pay down your balance as much as you can before canceling. If you have a remaining balance after cancellation, Discover will continue to charge interest on it until you pay it off. You can ask the representative during your cancellation call whether you can set up a payment plan, but it's simpler to clear the balance beforehand.

Check your rewards balance and redeem any points you've earned. Once the account closes, you typically have 30 to 60 days to use remaining rewards, though the exact window depends on your card terms. After that window closes, unused rewards are forfeited. Log into your Discover account online to see your current points balance and redeem them before you call.

Review your recent statements to make sure there are no pending transactions or recurring charges linked to the card. If you have automatic payments set up (utilities, subscriptions, insurance), update those accounts with a different payment method before canceling. Discover will decline any charges that hit after the account closes, which can result in late fees or service interruptions.

What happens to your credit after cancellation

Closing a credit card account can lower your credit score in the short term, usually by 5 to 10 points, though the impact varies depending on your overall credit profile. The drop occurs because closing an account reduces your total available credit, which increases your credit utilization ratio — the percentage of your total credit limit that you're using across all accounts.

The account will remain on your credit report for 7 to 10 years after closure, showing as "closed by consumer." This is normal and does not harm your credit. In fact, having a long history of accounts in good standing helps your credit score over time.

If you're concerned about the impact on your credit score, you can cancel after paying off the balance and then wait a few months before applying for new credit. This gives your score time to recover from the temporary dip.

If you want to cancel online or by mail instead

Discover does not offer a direct online cancellation option through their website or mobile app. You must call customer service or send a written request by mail. Calling is faster and gives you immediate confirmation, but if you prefer a paper trail, you can send a letter.

To cancel by mail, write a letter to Discover requesting account closure. Include your full name, card number, date of birth, and the reason for cancellation (optional). Send it to Discover's mailing address, which you can find on the back of your card or on their website. Mail takes 5 to 7 business days to arrive, plus additional time for Discover to process the request. This method is slower than calling and does not close the account immediately.

Handling a balance after cancellation

If you cannot pay your full balance before canceling, tell the Discover representative during your cancellation call. They can explain your options, which typically include continuing to make monthly payments on the closed account or setting up a payment plan. Discover will continue to charge interest on any remaining balance until it's paid off, so the longer you carry the balance, the more interest you'll pay.

Make sure you understand the interest rate and payment terms before you hang up. Ask the representative to confirm the minimum monthly payment and the total interest you'll pay if you make only minimum payments. Write down this information so you have it in writing from the call.

After the account closes, you'll still receive monthly statements showing your balance and minimum payment due. Pay at least the minimum each month to avoid late fees and further credit damage. You can pay online, by phone, or by mail using the payment instructions on your statement.

What to do with the physical card

After you cancel, cut up your Discover card or shred it to prevent unauthorized use. Do not throw it away whole, as someone could find it and attempt to use it. Cutting the card into pieces makes it unusable.

You do not need to return the card to Discover. Destroying it yourself is sufficient. If you prefer, you can call Discover after cancellation and ask for a prepaid return envelope, though this is not required.

Frequently Asked Questions

Can I cancel my Discover card if I still have a balance?

Yes, you can cancel even with a balance. Discover will close the account and continue charging interest on what you owe until you pay it off. It's better to pay the balance first if you can, but cancellation is not blocked by an outstanding balance.

Will canceling my Discover card hurt my credit score?

Your score may drop temporarily by 5 to 10 points because closing the account reduces your available credit. The impact is usually short-term and recovers within a few months. The account will stay on your credit report for 7 to 10 years, which is normal and does not harm your score long-term.

How long does it take for Discover to close my account after I call?

The account closes the same day you call. You'll receive written confirmation in the mail within 7 to 10 business days. Any charges attempted after your call will be declined.

What happens to my rewards points after I cancel?

You have 30 to 60 days after cancellation to redeem your remaining rewards points. After that window closes, unused points are forfeited. Log into your account and redeem your points before you call to cancel.

Do I have to return my Discover card to them?

No, you do not need to return the card. Cutting it up or shredding it yourself is sufficient. Destroying the card prevents anyone from finding it and attempting to use it.
