How to cancel Discover Card by mail

  1. Gather your account details

    Before writing, collect the account email, the last four digits of the linked bank account or card and the membership tier. Discover Card can only act on a request it can match to an account.

  2. Write your request

    Ask Discover Card to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Subscription termination – Discover Card”.

  3. Mail the letter with a receipt

    Post it by certified mail to Discover Card in Charlotte, United States, using the exact address below, and note the tracking number.

  4. Save the tracking record

    File the receipt with the letter. A Discover Card charge dated after delivery is the one to dispute, and these two documents are what you quote.

With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a finance or credit subscription

Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.

If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.

Discover Card lets you cancel directly (notify the card company: call 1-800-347-2683 (24/7) or log in to start a live chat; accounts already moved to Capital One are managed at capitalone.com or in the Capital One app). A letter is the fallback that leaves a dated record when the direct route fails.

Discover Card cancellation questions

Where do I send my Discover Card cancellation letter?

Our records list a dedicated cancellation box for Discover Card: Capital One, PO Box 71083, Charlotte, NC 28272-1083. Address the letter there, not to the head office.

How long does a cancellation letter to Discover Card take?

Discover Card's address is in North Carolina. USPS states that First-Class Mail is delivered in 1 to 5 days. The delivery receipt records the day your letter actually arrived, and that is the date to quote. USPS: First-Class Mail

What should I check before I cancel Discover Card?

For a finance or credit subscription: settle any outstanding balance first. Closing a membership does not clear what you owe.

What do I need to cancel Discover Card?

Have the account email, the last four digits of the linked bank account or card and the membership tier to hand. The details in the letter need to match what Discover Card has on file.

Will Discover Card confirm my cancellation?

The letter asks Discover Card to end the account, stop further charges and confirm in writing, but a reply is not guaranteed. What you can rely on is the delivery receipt: it shows the date Discover Card received the request. If a charge posts after that date, quote the receipt with your copy of the letter.
