DD Form 254 is a Department of Defense form, not a service form: DD 254, DoD Contract Security Classification Specification, used to Department of Defense Contract Security Classification Specification ( Instructions ). The DD prefix is the operative fact. It means one blank serves every military department — Army, Navy, Air Force, Marine Corps, Space Force, Coast Guard under Defense jurisdiction — plus the defense agencies and combatant commands. No branch variant exists.
Authority: not stated prescribes it, not stated maintains it. Those two names settle most disputes about why the form is being asked for. Local commands add timing on top; the requirement itself comes from above them.
Use not stated, status not stated. Older printings circulate widely and lose their currency Department-wide the moment a new edition issues.
The set is PDF. Size: 1 pages, about 135 fields.
Nothing costs anything here. Work in a full desktop pdf application rather than a browser preview; field behaviour in browsers is unreliable.

Verify the edition before the first keystroke. The date on the form face should read not stated. If it does not, discard the file. Field numbering shifts between editions, and on a DD form the new layout reaches every receiving office in every service at once — there is no lag during which the old version is still normal somewhere.
Field-level questions go to the printed instructions, then to not stated, which is authoritative.
Send it as not stated or local guidance specifies. Save a copy. Cross-service and cross-agency routing is normal for Department forms, and a lost original outside your own organization is harder to chase down.
A number is a complete address in the DD series. Because the sequence is Department-level and not duplicated per service, there is nothing further to specify.
Prefix before number. A DA citation and a DD citation in the same instruction point at separate systems — one Army, administered by an Army proponent, one Department-wide under not stated — and there is no correspondence between them at any number.
Editions change when the prescribing directive is reissued, when the data collected changes, or when notice language is amended. None of that reaches you. Checking not stated at download is the entire defence, and it is cheaper than repeating a submission.
This page publishes a Defense document and explains its contents. It does not advise, does not rule on applicability, and determines nothing about how a completed form will be treated. Direct such questions to not stated, to the servicing personnel office, or to the office designated in not stated.
