Canceling a Discover card takes about 10 minutes on the phone, but the timing matters — closing an account can affect your credit score for months
Call Discover's customer service at 1-800-347-2000 and tell them you want to close your account. They will ask why, try to keep you as a customer, and then process the cancellation. Your card stops working when ready, but your account stays open for billing purposes until any remaining balance is paid off. Discover will send you a confirmation letter in the mail within a few days.
Before you call, pay down your balance as much as possible. Closing an account with a balance still owed doesn't hurt you more than keeping it open, but it does mean you'll keep getting statements and paying interest until it's gone. If you have a $0 balance, the account closes cleanly.
Key Takeaways
- Call Discover at 1-800-347-2000 during business hours to request cancellation — there is no online option.
- Pay your balance to $0 before calling if you can, so the account closes without ongoing statements or interest charges.
- Your credit score may drop temporarily because closing an account reduces your available credit and changes your credit history length.
- Discover will mail a confirmation letter, but keep your own record of the cancellation date and confirmation number from the call.
- If you have pending rewards points, redeem them before canceling — you lose them once the account closes.
Why your credit score drops when you close a card
Closing a credit card removes available credit from your total. If you had a $5,000 limit and $1,000 in debt across all your cards, your credit utilization was 20%. After closing that card, your available credit shrinks, and the same $1,000 debt now represents a higher percentage of what you can borrow. This ratio — called credit utilization — makes up about 30% of your credit score calculation.
The drop is usually temporary. Your score recovers over several months as you keep paying on time and the closed account ages. The older the account, the less damage closing it does. A card you've held for 10 years hurts less to close than one you opened last year.
If your credit score is already low or you're planning to borrow money soon — a mortgage, car loan, or new credit card — wait to close the account until after you've finished borrowing. The timing of the cancellation matters more than whether you do it.
What happens to your balance and rewards
Closing the account does not erase what you owe. If your Discover card has a $2,000 balance, that debt stays with you. You'll continue receiving monthly statements and paying interest until the balance reaches $0. The card itself stops working, but Discover keeps the account open for billing.
Redeem any rewards points before you call to cancel. Once the account closes, you lose access to unused points — Discover does not transfer them to another card or pay them out in cash. Check your rewards balance in the Discover app or online account, and convert points to a statement credit or cash back before you hang up the phone with customer service.
Timing: when to cancel and when to wait
Cancel when ready if the card charges an annual fee and you're not using it. There's no benefit to keeping a paid card open if you don't need it. If the card is free, you can cancel anytime, but consider waiting if any of these explore: you're explore for a mortgage or car loan in the next 3 to 6 months, your credit score is below 650, or you have high balances on other cards.
If you're canceling because you're unhappy with the card's rewards or benefits, call first and ask if Discover offers a different card you could switch to instead. Moving to a different Discover product keeps the account open and avoids the credit score hit entirely. Discover customer service can discuss product changes without requiring a full cancellation.
The cancellation call: what to expect
Discover's customer service team will ask why you're closing the account. Common reasons are switching to another card, not using the card, or dissatisfaction with rewards. Be honest but brief — you don't owe them a detailed explanation. They may offer you a better rewards rate, a fee waiver, or a statement credit to keep you. You can accept or decline.
Once you confirm you want to close the account, the representative will give you a confirmation number and the date the account closes. Write both down. Ask them to email or mail a written confirmation, though most will only mail it. The call takes 5 to 10 minutes total.
After the call, log into your Discover account online to confirm the status shows "closed" or "closing." If you see any charges after the cancellation date, contact Discover when ready — they may have processed a recurring payment or merchant charge after you closed it.
What to do with the physical card
Cut up the card or shred it once the account is closed. Do not throw it away whole — a card number is enough for fraud. You don't need to return it to Discover; destroying it yourself is standard practice.
If you're worried about identity theft, you can also request a new card number before canceling, use it for a few weeks, and then cancel the old number. This gives you a fresh card number in your records and reduces the risk that the old number is floating around somewhere.
Alternatives to canceling
If you're canceling because you don't use the card, consider keeping it open instead. A card you never use doesn't hurt your credit as long as there's no annual fee. It actually helps by keeping your available credit high and your credit history long. Put it in a drawer and forget about it.
If you're canceling because of high interest rates or poor rewards, switching to a different card is usually better than closing the account. You keep the credit history and available credit, and you only take a small hit from the new account inquiry. Discover offers several card types — cashback, travel, student — so you may find a better fit without leaving the company.
Frequently Asked Questions
Will Discover try to keep me from canceling?
Yes. Customer service will offer incentives like a higher rewards rate, a one-time statement credit, or a waived annual fee. You can accept any offer or decline and proceed with cancellation. Saying no doesn't change the process — they will close the account if you ask them to.
Can I cancel online or through the app?
No. Discover requires a phone call to 1-800-347-2000. There is no online cancellation option. You must speak to a representative, though the call is quick and you don't need to schedule it in advance.
What happens to my credit history after I close the account?
The account stays on your credit report for 7 to 10 years after closing, so the history doesn't disappear when ready. This is actually helpful — older accounts help your credit score. The account will eventually fall off your report, but only after a decade.
Do I lose my rewards points when I cancel?
Yes. Any unused rewards points are forfeited once the account closes. Redeem them for a statement credit or cash back before you call to cancel. Discover does not transfer points to another card or pay them out separately.
Can I reopen a Discover card after I close it?
You can explore for a new Discover card after closing one, but Discover may treat it as a new account rather than reopening the old one. If you think you might want the card back, consider keeping it open instead — the cost is zero if there's no annual fee.
