Download the form

DD Form 448 is a Department of Defense form, not a service form: Military Interdepartmental Purchase Request, used to Military Interdepartmental Purchase Request. 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.

Available: PDF, across unknown pages, roughly unknown fields. That is the whole scope of the download decision.

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.

Edition check comes first, ahead of any entry. Compare the printed date to not stated and replace anything older. Department-level supersession is simultaneous across the services, so a superseded blank is not merely out of date locally; the office receiving it is already working from the new field structure whichever branch it belongs to.

Field-level questions go to the printed instructions, then to not stated, which is authoritative.

Submit to the office named in not stated or in local instruction; retain a duplicate before it leaves. Joint routing often sends a DD form across organizational boundaries, and tracing one afterward is not a same-day matter.

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.

Do not read across from a service number. DA numbering is Army-specific under an Army proponent; DD numbering is Department-wide under not stated or an equivalent Department office. The sequences are unrelated, so identical digits in each identify two different documents. Read the prefix, not the digits.

Three drivers of revision: directive reissue, altered collection requirements, updated statutory notice text. No notification accompanies any of them, so download fresh and confirm not stated rather than reusing an archived file.

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.
