The basic steps to close a Discover card
To close your Discover card, call Discover's customer service at the number on the back of your card or visit your online account and request closure through the messaging system. Discover will confirm your request and may ask why you're closing the account — this is optional to answer. The account will be marked as closed by the customer, and you'll receive written confirmation by mail within a few days.
Before you call, pay off any remaining balance on the card. Discover will not close an account with an outstanding balance, and if you stop using the card without paying what you owe, the account remains open and you'll continue to accrue interest and fees. Paying the full balance first makes the closure process immediate.
After closure is confirmed, your card will no longer work for new purchases. Any pending transactions that haven't yet posted may still go through, so check your account for a few days after closure to catch any unexpected charges. Once those clear, the account is fully closed.
Key Takeaways
- Call Discover customer service or use your online account to request closure, and pay off your full balance before you do.
- Discover will send written confirmation of closure by mail, and your card stops working for new purchases immediately.
- Check your account for a few days after closure to catch any pending transactions that may still post.
- Closing a credit card can lower your available credit and raise your credit utilization ratio, which may affect your credit score temporarily.
- If you want to keep the account open but stop using it, you can simply cut up the card and leave the account inactive instead.
What happens to your credit score when you close a card
Closing a credit card can lower your credit score in the short term because it reduces your total available credit. If you have balances on other cards, closing one card makes those balances represent a larger percentage of your total credit limit — a metric called credit utilization. The higher your utilization, the lower your score tends to be.
The impact is usually temporary. As you pay down balances on your remaining cards, your utilization improves and your score recovers. The closure itself stays on your credit report for about 10 years, but its effect on your score fades after a few months to a year.
If the Discover card is your oldest account, closing it can also lower your average account age, which factors into your score. This effect is usually small and also fades over time as other accounts age.
What to do with rewards points before closing
Discover allows you to redeem cash back rewards before or after you close your account. If you have cash back sitting in your account, redeem it before closure to make sure you receive it. After closure, you have a limited window to redeem remaining rewards — Discover's policy allows redemption for a period after account closure, but the exact timeframe depends on your account status.
Contact Discover to confirm your rewards balance and redemption options before you close. If you have a small balance that's not worth redeeming, ask whether it will be forfeited or held in your account after closure.
Reasons to keep the account open instead
If your main concern is not using the card, you don't have to close it. You can simply stop using it and leave the account open. This preserves your available credit, keeps your average account age intact, and avoids the temporary score dip that closure causes.
The downside is that inactive accounts sometimes get closed by the card issuer after a long period of no activity — Discover's policy varies, but many issuers close accounts after 12 months or more of inactivity. If you want to keep the account open, make a small purchase every few months and pay it off to show activity.
Keeping an old card open also protects you if you ever need emergency credit. The account remains available even if you don't use it regularly.
How to close a Discover card if you can't reach customer service
If you're unable to reach Discover by phone, you can request closure through your online account dashboard. Log in, navigate to account settings, and look for a "close account" or "account management" option. The online method creates a record of your request and usually generates a confirmation number.
You can also send a written request by mail to Discover's customer service address, which you'll find on your statement or the Discover website. Include your account number, full name, and a clear statement that you want to close the account. Send it certified mail so you have proof of delivery.
What happens after your account closes
Once your account is closed, you can no longer use the card for purchases. Any recurring charges tied to the card — subscriptions, automatic payments, or other recurring transactions — will be declined. Before closing, update any recurring payments to a different card or payment method.
Your closed account will still appear on your credit report, and the payment history associated with it remains part of your credit record. This is actually beneficial because a long history of on-time payments helps your score even after the account closes.
If you ever want to reopen the account, contact Discover to ask whether they'll reopen it. Some issuers will reopen closed accounts within a certain timeframe, but this is not may provide and depends on the reason for closure and your account history.
