Call Discover's customer service number to request cancellation

The fastest way to cancel a Discover card is to call Discover directly. The number is on the back of your card. Have your card number ready when you call. A representative will ask why you're cancelling — you don't have to give a detailed reason, but they may offer you a retention offer (like a lower interest rate or fee waiver) to keep the account open.

Tell the representative clearly that you want to close the account. They will process the cancellation immediately and confirm it in writing. Ask them to note in your file that you requested the closure, so there's a record if questions come up later.

Cancellation is free. Discover will not charge you a fee to close the account, whether you cancel online, by phone, or by mail.

Key Takeaways

  • Call the number on the back of your Discover card to cancel; the process takes a few minutes and costs nothing.
  • Pay off your full balance before cancelling, or your remaining balance will still be due and will accrue interest if you don't pay it.
  • Closing a credit card can lower your credit score slightly because it reduces your total available credit, but the effect is usually temporary.
  • After cancellation, keep your final statement and confirmation letter in case billing disputes arise later.

What to do with your remaining balance

If you have an unpaid balance on your Discover card when you cancel, the account will close but you will still owe the money. Discover will continue to charge interest on the remaining balance until you pay it off. You can pay the balance in full before you call to cancel, or you can cancel and then pay the balance in installments afterward.

If you plan to pay over time, ask the representative during the cancellation call whether closing the account will change your interest rate or payment terms. Some issuers keep the same rate after closure; others may adjust it. Getting this in writing protects you if a dispute arises later.

Cancellation and your credit score

Closing a credit card typically lowers your credit score by a small amount in the short term. This happens because closing an account reduces your total available credit, which changes your credit utilization ratio (the amount you owe divided by the amount you can borrow). The effect is usually temporary — your score typically recovers within a few months if you keep other accounts in good standing and pay bills on time.

The impact is smaller if you have other credit cards open. If this is your only card or your oldest card, the effect may be slightly larger. If you're planning to apply for a loan or mortgage soon, you may want to wait a few months after cancellation before applying, to give your score time to recover.

Steps to take before you cancel

Before you call Discover, take these steps to protect yourself:

  1. Pay off your full balance, or know what you still owe and have a plan to pay it.
  2. Check your recent statements for any recurring charges (subscriptions, automatic payments) linked to this card and update them to a different payment method.
  3. Review your rewards balance. If you have Discover cashback or points, redeem them before you cancel — you may lose them after the account closes.
  4. Take screenshots or print copies of your account summary, recent statements, and any rewards balance for your records.

Cancelling by mail if you prefer not to call

You can also cancel by sending a written request to Discover's mailing address. Write a letter stating your name, account number, and request to close the account. Send it certified mail with return receipt so you have proof Discover received it. This method takes longer — typically one to two weeks — but creates a paper trail.

Some people prefer this method if they want to avoid a retention pitch or if they have difficulty making phone calls. The outcome is the same: your account will be closed and you'll receive written confirmation.

What happens after cancellation

After your account closes, Discover will send you a final statement showing any remaining balance. If you owe money, you can pay it by phone, mail, or online through your Discover account (which remains accessible for billing purposes even after closure). Your account will appear as "closed" on your credit report, which is normal and expected.

Keep your cancellation confirmation letter and final statements for at least one year. If a billing error or dispute comes up later, you'll need proof that you closed the account and when. Discover's customer service can look up closed accounts, but having your own records speeds up the process.

Frequently Asked Questions

Will Discover let me reopen my account after I cancel?

Discover may let you reopen a closed account within a certain period, usually 30 to 60 days, without a new application. After that window, you would need to apply as a new customer. Call Discover if you change your mind shortly after cancelling to ask whether your account can be reopened.

What if I have a pending charge that hasn't posted yet?

Pending charges can still post after you cancel. Make sure your account remains active long enough for all charges to clear, or contact the merchant to cancel the transaction before you close the card. If a charge posts after closure, you can still dispute it or pay it from your closed account.

Does cancelling hurt my credit more than just not using the card?

Closing the account has a slightly larger short-term impact than leaving it open unused, because it reduces your available credit immediately. However, if you're not using the card anyway, the long-term benefit of closing it (no risk of fraud, no annual fee if one applies) usually outweighs the temporary score dip.

Can I cancel if I have a balance transfer or promotional rate?

Yes, you can cancel even if you're in the middle of a promotional period. However, closing the account may end the promotional rate and cause interest to apply to the remaining balance at the regular rate. Check your terms before cancelling, or ask the representative what will happen to your balance and rate after closure.
