Does Discover close inactive credit cards?

Discover closes credit cards that go unused, and the one report on record says it will not reopen them. That report, collected by Doctor of Credit, describes a Discover it card closed after about 18 months without a purchase, following a 30-day warning by mail. No Discover consumer card carries an annual fee, so every idle one is exposed. A purchase every nine months keeps a Discover card inside the report.

What the record shows

The figures come from one cardholder's report, collected by Doctor of Credit and kept by ActiveCred in a public data file checked on November 14, 2026. They are a report, not Discover policy.

A single report is a weak basis for a window. It sits inside the range at the other large banks, from about 10 to 12 months at Wells Fargo to two years or more at Bank of America, Capital One and Citi, but Discover could close sooner in other cases. The issuer-by-issuer record has the comparison.

Doctor of Credit's list dates from 2019, with reader reports added since, and a bank can change its practice without announcing it. The figures are the best public record, not a promise. At Discover, with one report and a refusal to reopen behind it, the margin should be wider than usual.

Discover now belongs to Capital One

Capital One completed its purchase of Discover in May 2025. Discover cards still carry the Discover name, and the report above predates the merger. Capital One is reported to be among the slowest of the large banks to close unused cards, at about two to four years, but there is no record yet of how it treats Discover cards. The safe course is to assume nothing has been relaxed.

How Capital One treats its own cards covers that side of the record.

The letter matters more here

A 30-day letter by mail is a useful warning: dated, specific and long enough to act on. At Discover it carries more weight than at most banks, because the same cardholder found that the account could not be reopened afterwards without a new application.

No law requires the letter. Regulation B excludes actions taken because of inactivity from the rules that make lenders explain adverse decisions. A cardholder who has moved since last using the card, and not updated the address, may never see it. The notice record across banks shows how uneven warnings are.

If the card has already closed

The one report says Discover would not reopen without a new application. That is a single account, and asking costs nothing. Call, say the card was closed for inactivity, and ask whether it can be reopened as the same account. What other banks are reported to allow is in the reopening guide.

If the answer is no, a new application brings a hard inquiry and a new account with a new opening date. The closed account stays on the credit report for up to ten years if it was in good standing, according to Experian, and keeps counting toward the average age of accounts until it drops off.

No Discover card has a fee to protect it

Annual fees protect many cards at other banks, because the fee posts every year and appears to count as activity. Discover's consumer cards carry no annual fee, so none of them has that cover. Discover it Cash Back, Discover it Miles, Discover it Chrome and the secured card all need a purchase to stay active.

Cash back is the easiest reward to protect, because it can be redeemed at any time. Redeeming it before a card goes idle settles what happens to it at closure. For a Discover secured card, inactivity has a second cost: Discover describes automatic reviews for graduation from month seven, and an unused card gives that review little to go on.

Checking a Discover card that has sat unused

The quickest test is a small purchase. If a $1 charge goes through and posts, the card is open and its clock has just been reset. If it is declined, the account may have been closed, or the bank's fraud checks may want to confirm the purchase; a large or unusual charge after months of silence can be refused while the account stays open. Discover's app or website shows a closed account as closed, or drops it from the list.

The credit report settles whether the account is open. Reports from all three bureaus are free every week at annualcreditreport.com, and an account the bank has closed carries a remark such as "closed by credit grantor". The date of the last purchase is on the statements. Five ways to check a card sets out the rest.

Only a purchase that posts to the statement counts as use. Payments, refunds and logging in do not reset the clock, and a balance transfer is not a purchase. What counts as activity has the detail.

The safe cadence

ActiveCred's rule is a cadence no longer than half the shortest reported closure. Half of Discover's 18 months is nine, so a newly linked Discover card is charged every nine months unless the cardholder picks another schedule. With one report behind the figure, there is a fair case for picking a shorter one.

Every three months is the obvious choice. It is the schedule ActiveCred gives a card from a bank with no reports, and it clears the shortest closure reported at any large bank, about 10 months at Wells Fargo, with seven months to spare. A cardholder with cards from several banks can put them all on it.

For a card whose last purchase date is known, the inactivity checker, set to Discover shows how far into the reported window it is and the date to use it by.

In short

Discover's record is one report: about 18 months, a 30-day letter, and no way back without a new application. Thin evidence argues for caution, not comfort. At a bank that will not reopen an idle card, the purchase made in time is the only protection that counts.
