Distribution Statements

Also known as: DoD Distribution Statements

Simply put

Distribution statements are standardized labels applied to certain Department of Defense documents that specify how a document may be shared and who is permitted to receive it. They are typically required for DoD-funded documents and help control the release and reuse of technical information. The statements range across several categories, generally lettered A through F, each indicating a different level of permitted distribution.

Formal definition

Distribution statements are standardized markings used by the U.S. Department of Defense to indicate who may access, share, or reuse a given document, and under what conditions. Controlled technical information is generally to be marked with one of the distribution statements B through F in accordance with applicable DoD guidance, while Distribution Statement A denotes approval for public release with unlimited distribution. Application varies by category; for example, Distribution Statement F is not to be used on classified, CUI, or unclassified scientific or technical information, per DoD CUI Program guidance. Practitioners should note that distribution statements govern release and dissemination and are distinct from classification levels and from CUI category markings, and the specific criteria and applicable DoD instruction should be verified against current authoritative sources.

Why it matters

Distribution statements are the mechanism by which the Department of Defense communicates, on the face of a document, how technical and scientific information may be shared and who is permitted to receive it. Because these markings travel with the document, they help ensure that controlled technical information does not flow to unauthorized recipients as documents are copied, forwarded, or reused across programs, contractors, and government agencies. A missing or incorrect distribution statement can lead to improper release of information that was intended for a limited audience, or conversely can unnecessarily restrict information that was approved for public release.

For contractors and program offices, correct application matters because these statements often accompany DoD-funded documents and shape downstream handling obligations. It is a common mistake to treat distribution statements as interchangeable with classification levels or with CUI category markings. They are distinct: distribution statements govern release and dissemination, while classification and CUI markings address the sensitivity and safeguarding category of the information itself. A document can carry a distribution statement in addition to, and separately from, any applicable classification or CUI marking, and confusing these regimes can result in mismarked or mishandled information.

Application rules also carry specific limits that practitioners must respect. For example, per DoD CUI Program guidance, Distribution Statement F is not to be used on classified, CUI, or unclassified scientific or technical information. Because the specific criteria, permitted categories, and the applicable DoD instruction can change, readers should verify the current authoritative text rather than rely on general summaries when determining which statement applies.

Who it's relevant to

Government Contractors and Subcontractors

Contractors handling DoD-funded documents encounter distribution statements on technical and scientific information they receive or produce. They need to understand which recipients are permitted under each statement and how these markings interact with, but remain distinct from, classification and CUI category markings that may also apply.

DoD Program Offices and Technical Document Authors

Program personnel and authors responsible for DoD-funded documents apply distribution statements to communicate permitted dissemination. They must select the correct category, observe exclusions such as the limits on Distribution Statement F, and verify the applicable DoD instruction against current authoritative sources.

Information Marking, Records, and Compliance Staff

Personnel responsible for marking, releasing, and controlling documents rely on distribution statements to govern release and dissemination. They should ensure statements are applied and interpreted separately from classification levels and CUI markings to avoid mismarking or improper release.

Auditors and Assessors Reviewing Information Handling

Those evaluating a contractor's or program's handling of controlled technical information may examine whether distribution statements are correctly applied and consistent with applicable DoD guidance, keeping in mind that criteria and governing instructions can change across revisions.

Inside Distribution Statements

Distribution Statement Designation

A marking (commonly lettered, such as Distribution Statements A through F) applied to technical documents to indicate the authorized audience and any limitations on secondary distribution. Each designation corresponds to a defined level of dissemination control, ranging from approved for public release to distribution limited to specified recipients.

Reason for Restriction

The basis cited for limiting distribution, which may include categories such as export control, proprietary information, critical technology, operational security, or other administrative or operational considerations. The applicable reason is generally recorded as part of the marking so recipients understand why dissemination is constrained.

Controlling DoD Office

The office designated as responsible for the document, to which requests for the document or for release determinations are directed. Distribution statements that limit dissemination generally identify this office so that recipients know the authority to contact regarding further release.

Date of Determination

The date on which the distribution statement was assigned or the release determination was made. Because determinations can be reassessed, the date helps recipients understand the currency of the marking. Verify current formatting requirements against the applicable governing publication.

Relationship to CUI Marking

Distribution statements are a dissemination-control mechanism that may accompany, but is distinct from, Controlled Unclassified Information (CUI) markings and classification markings. A document may carry a distribution statement in addition to other required markings, and each serves a different control function.

Common questions

Answers to the questions practitioners most commonly ask about Distribution Statements.

Are distribution statements the same as security classification markings?

No. Distribution statements and classification markings are distinct control mechanisms that are often confused. Classification markings (such as CONFIDENTIAL, SECRET, or TOP SECRET) identify national security information and are governed by executive order and associated security policy. Distribution statements, by contrast, control the secondary dissemination and release of technical documents and generally apply to both classified and unclassified technical information. A document can be unclassified yet still carry a distribution statement restricting who may receive it. Because the two serve different purposes, applying one does not satisfy the requirements of the other, and readers should confirm the specific marking requirements against the current governing DoD policy.

If a document has no distribution statement, does that mean it is approved for public release?

Not necessarily. The absence of a distribution statement should not be interpreted as authorization for unlimited public release. In most DoD implementations, technical documents are expected to carry an appropriate distribution statement, and a missing statement generally indicates an unmarked or improperly processed document rather than a public-release determination. Public release typically requires a separate, affirmative review and approval process. Treating unmarked material as releasable is a common and consequential mistake; the safer course is to withhold further dissemination and confirm the intended distribution status with the originating or controlling office.

Who has the authority to assign or change a distribution statement on a document?

Distribution statements are generally assigned by the controlling DoD office, typically the originator or the office with responsibility for the technical content. Changing or removing a statement is normally reserved to that controlling office rather than to downstream recipients. Because specific delegation and approval procedures vary by component and by the governing policy revision, readers should verify who holds this authority for their particular document and organization against current official guidance before altering any statement.

How should a distribution statement appear on a document?

In most implementations, a distribution statement is placed conspicuously on the document so that recipients can readily identify the dissemination restrictions, and it commonly includes the reason for the restriction and the identity of the controlling office. The exact placement, format, and required elements are specified in the applicable DoD policy and may differ across components or document types. This entry does not prescribe formatting specifics; confirm the precise marking format against the current authoritative text.

What should a recipient do before forwarding a document that carries a distribution statement?

A recipient should read the statement to determine the permitted audience and any conditions on further release, and should generally not redistribute the document beyond the authorized scope without approval from the controlling office. When the intended recipient or purpose falls outside the stated distribution, the appropriate step is typically to route the request back to the controlling office rather than to make an independent release decision. Specific handling obligations depend on the governing policy and any contractual terms, which the recipient should confirm.

How do distribution statements relate to handling Controlled Unclassified Information (CUI)?

Distribution statements and CUI markings address related but separate concerns. A distribution statement controls dissemination of a technical document, while CUI markings identify information requiring safeguarding under the applicable CUI framework. A document may carry both, and the presence of one does not replace the requirements of the other. Because the interaction of these marking regimes is governed by distinct authorities and may be tailored by agency or contract, readers should verify the combined marking and handling requirements against current official sources rather than assuming one set of controls subsumes the other.

Common misconceptions

A distribution statement is the same as a classification marking.

A distribution statement controls the authorized audience and secondary dissemination of a document; it is not a security classification. A document can carry a distribution statement while being unclassified, and classified documents carry separate classification markings in addition to any distribution controls. The two mechanisms serve different purposes and should not be treated as interchangeable.

A distribution statement of 'approved for public release' means the information carries no other handling obligations.

Even where a document is approved for public release, other obligations such as CUI handling, export control considerations, or contractual requirements may still apply to related information or to different documents. Public-release approval addresses dissemination of that specific document and does not by itself remove all other controls; confirm the full set of applicable markings and requirements.

Once assigned, a distribution statement is permanent and never needs review.

A distribution determination reflects conditions at the time it was made and can be reassessed. Changes in the sensitivity, export status, or operational relevance of the information may warrant a revised statement. Treat the marking as tied to its date of determination and verify it remains current against the controlling office and applicable guidance.

Best practices

Confirm the applicable distribution statement designation and its precise wording against the current governing publication rather than relying on legacy templates, as marking requirements can change across revisions.

Identify and record the controlling office and the reason for restriction so recipients know both why distribution is limited and where to direct release requests.

Treat distribution statements as distinct from, and potentially additive to, CUI and classification markings, and confirm that all required marking types are applied where each applies.

Include the date of determination and periodically review whether the assigned statement still reflects the current sensitivity, export, or operational status of the information.

Route any public-release or downgrade determination through the designated controlling office or release authority rather than making an independent judgment.

When in doubt about the correct designation or its implications for export control or contractual obligations, verify with the controlling office and confirm against current official sources before dissemination.
