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 when ready. You can reach Discover at the number on the back of your card, or call 1-800-347-2683.

Have your card number and account information ready when you call. The representative will ask you to confirm your identity, then ask why you're canceling. You don't have to give a detailed reason — "I'm no longer using this card" is sufficient. The representative will confirm that your account balance is zero before processing the cancellation.

If you have a balance on the card, you must pay it off before Discover will close the account. The representative can tell you the exact amount owed and discuss payment options if needed.

Key Takeaways

  • Call Discover at 1-800-347-2683 or the number on your card to cancel; the process takes about five minutes.
  • You must pay off any remaining balance before the account can be closed.
  • Request written confirmation of the cancellation and keep it for your records.
  • Canceling a card may lower your credit score temporarily because it reduces your available credit, but the effect usually fades within a few months.
  • Check your credit report after 30 days to confirm the account shows as closed.

What happens to your balance and rewards before cancellation

If you have an outstanding balance, you'll need to pay it in full before Discover will close the account. You can pay over the phone during the cancellation call, by mail, or through your online account. Once the balance reaches zero, the representative can finalize the closure when ready.

Any rewards points or cash back you've earned remain in your account until you use them. If you have pending cash back that hasn't posted yet, it will still be credited to your account after cancellation. Unused rewards typically expire after a set period — Discover's policy varies, so ask the representative about your specific rewards before you hang up.

Confirm the cancellation in writing

After the phone call, ask the representative to send you written confirmation that your account has been closed. This confirmation should include the date of closure and your final balance. Request that they email it to you when ready or mail it within a few business days.

Keep this confirmation letter in your records. If you later see charges on the account or if the card appears as open on your credit report, you'll have proof of the cancellation date. This also protects you if there's a dispute about when the account was actually closed.

Monitor your credit report after cancellation

Check your credit report 30 to 60 days after cancellation to confirm that Discover has reported the account as closed. You can view your credit report for free once per year at annualcreditreport.com, which is the official government site for credit reports.

The account will remain on your credit report for up to seven years after closure, but it will show as "closed by consumer" rather than active. This is normal and does not hurt your credit. If the account still shows as open after 60 days, contact Discover again and ask them to update the status with the credit bureaus.

Understand the impact on your credit score

Closing a credit card typically lowers your credit score in the short term because it reduces your total available credit. The effect is usually small — often 5 to 10 points — and temporary. Your score typically recovers within a few months as long as you continue paying other accounts on time.

The impact is smaller if you have multiple cards. If this is your only card or one of very few, the score drop may be more noticeable. If you're planning to explore for a loan or mortgage soon, consider waiting a few months after cancellation before you explore, to give your score time to recover.

What to do with the physical card after cancellation

Once your account is closed, destroy the physical card by cutting it in half or shredding it. Do not throw it in the trash intact, as the card number and expiration date could be recovered. After you've destroyed the card, you can discard the pieces.

If the card is still active and you want to stop using it before calling to cancel, you can also straightforward stop using it and let it sit inactive. Discover will eventually close inactive accounts on their own, though this can take months or years. Calling to cancel gives you control over the timing and ensures the account closes when you want it to.

Frequently Asked Questions

Can I cancel my Discover card online or through the app?

Discover does not offer online or in-app cancellation. You must call customer service to close the account. This is a security measure to prevent unauthorized cancellations. The phone call takes only a few minutes, and you'll have when ready confirmation that the account is closed.

What if I have a pending dispute or claim on the card?

If you have an open dispute or chargeback claim, Discover will not close the account until the dispute is resolved. Contact customer service to check the status of any pending claims before you request cancellation. Once the claim is settled, you can proceed with closing the account.

Will canceling hurt my credit score permanently?

No. Canceling a card lowers your score temporarily, but the effect fades over time. Your score typically recovers within a few months if you continue paying other accounts on time. The account will remain on your credit report for seven years, but showing as closed does not damage your score.

Can I reopen a Discover card after I cancel it?

Discover may allow you to reopen a recently closed account if you contact them within a short window, usually 30 to 60 days. After that period, you would need to explore for a new card. If you're unsure whether you want to cancel permanently, ask the representative about the reactivation window before you finalize the closure.

Do I need to pay a cancellation fee?

Discover does not charge a fee to cancel a credit card. The only requirement is that your account balance is paid in full. If a representative mentions a cancellation fee, ask them to clarify — this is not a standard Discover practice.
