Download the form
DD Form 428 is a Department of Defense form, not a service form: Communication Service Authorization, used to Communication Service Authorization. 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.
Requirement traces to not stated; the form belongs to not stated. Everything about schedule sits below that in local instruction, which is where to ask if a date matters.
Current edition is not stated, carried as not stated. Check that against any copy you already hold before doing anything else — Department-level revisions land everywhere simultaneously, so a stale file is stale across the whole Department.
Formats: PDF. Length unknown pages, approximately unknown entries. Pick on the basis of how you will complete it.
Default to fillable pdf, print only when you must. The fillable file stores what you type; the printable file is a blank picture. A Department form often travels further than a service form — scanned, emailed, forwarded to an agency that never saw the original — and typed text is what survives that.
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.
Unclear entries — read the form face, then not stated; the directive prevails.
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.
Where a procedure cites both a service form and a DD form, the two are unconnected. Service numbering answers to a service proponent, DD numbering to not stated or another Department office, and the two sequences were never aligned. Matching numbers mean nothing whatever.
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.
Limits of this page: it distributes a published Department of Defense document and describes it. No legal advice, no procedural ruling, no statement about whether any submission will be accepted. Applicability, eligibility and procedure belong to not stated, to a servicing personnel office, or to the office named in not stated.
