DD Form 512 is a Department of Defense form, not a service form: Installation Custody Agreement, used to Installation Custody Agreement. 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.
Xfdl is a legacy Department format, IBM Lotus Forms, requiring the matching viewer. Its survival in DD distribution reflects how widely it was fielded across the Department, not any advantage over pdf today.
All formats are free. One operational note: save the file locally and open it in a desktop reader. Browser-embedded viewers drop field properties and lose typed data without warning.
Start by matching the printed date to not stated. Old blanks accumulate in shared folders for years. Because the Department reissues to all services in one action, nobody is still accepting the previous layout by local custom.
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.
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.
Revision follows directive changes, changed data requirements and amended notice language, unannounced. Verify not stated each time rather than trusting a saved copy — the cost of the check is seconds.
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.
