Is it true that a classified record automatically becomes unclassified after 25 years, so I can just shred it?

No. This is one of the most common and most dangerous misconceptions about classified material. Two separate ideas are being collapsed into one: the classification status of information and the authorized disposition of a record. They are governed by entirely different rules.

What “25-year” declassification actually means

Under the executive-order framework that governs national security classification, many permanently valuable historical records are subject to automatic declassification at a set age unless an exemption applies. But this rule does several things you should not assume:

• It changes the information’s classification status, not the fate of the document.
• It applies only to records that have been appraised as permanently valuable and slated for transfer to the National Archives.
• It is not automatic in practice for everything. Records can be exempted, referred to other agencies, or held for further review. The clock can also restart or never apply.

In other words, “declassified” means the information may now be releasable. It does not mean the record is yours to discard.

Why you cannot “just shred it”

Destroying a federal record is a separate, tightly controlled act. A record may be destroyed only when an approved records schedule authorizes it, regardless of classification status.

• Many declassified records are precisely the ones marked for permanent preservation at the Archives. Destroying them would be unlawful.
• Unauthorized destruction of federal records can carry serious legal and criminal consequences.
• Classification level and retention period are independent. A record can be unclassified and still required to be kept for decades, or kept forever.

What to do instead

1. Check the records schedule, not the classification stamp, to determine disposition.
2. Confirm the declassification status through your agency’s security or declassification authority before treating anything as releasable.
3. Never destroy a record without documented schedule authority and any required approvals.
4. Watch for litigation holds, FOIA requests, or investigations, which suspend all destruction.
