What Cover Sheet Is Attached to a SECRET Document?

The answer

The correct cover sheet for a SECRET document is Standard Form 704 (SF 704), commonly called the SECRET cover sheet. It is placed on top of any document, folder, or working paper that contains SECRET-classified information. The cover sheet's job is simple but important: it hides the first page of the material so that anyone walking past a desk, sitting in a meeting, or standing at a copier cannot casually read classified content. It stays with the document during use and handling and is only removed when the material is placed in approved secure storage or destroyed.

The three national-security classification cover sheets are a matched set defined by the U.S. Government (GSA Standard Forms):

• SF 703 — TOP SECRET (orange border)
• SF 704 — SECRET (red border)
• SF 705 — CONFIDENTIAL (blue border)

Each form is color-coded so handlers can instantly recognize the sensitivity level of what they are holding. For a SECRET document, that color is red, and the form number is 704.

Why the other forms are wrong

It is easy to confuse the three because they look nearly identical apart from color and label. SF 703 is reserved strictly for TOP SECRET material — the highest level, whose disclosure could cause exceptionally grave damage to national security. Using an SF 703 on a SECRET document would over-mark it and cause confusion about the true classification. SF 705 is the CONFIDENTIAL cover sheet, used for the lowest of the three classification levels, where disclosure could cause damage (but not serious or grave damage). Applying SF 705 to a SECRET document would under-protect it and mislabel its sensitivity.

Only SF 704 matches the SECRET level, whose unauthorized disclosure could reasonably be expected to cause serious damage to national security. Matching the correct cover sheet to the classification level is not just a formality — mismatched markings can lead to a security incident or spillage report.

The bigger picture

Cover sheets are a low-tech but effective layer in a defense-in-depth security system. They do not encrypt or lock anything; their entire purpose is to prevent inadvertent disclosure — the accidental glance, the document left face-up, the wrong page picked up from a shared printer. They complement, but never replace, proper secure storage (approved safes and containers), need-to-know access controls, and the classification markings printed on the document itself.

A useful memory aid is to picture a traffic-light-style ordering from most to least sensitive: 703 → orange → Top Secret, 704 → red → Secret, 705 → blue → Confidential. Red sits in the middle, just as SECRET sits between the highest and lowest classification levels. Remember that red equals SECRET equals SF 704, and the question answers itself.
