Which document is this? DD Form 878, official title Military Mail Dispatched. What does it do? It exists to Military Mail Dispatched. Everything on this page builds on those two facts.
Is there a version specific to your service? No. A DD number is issued at Department level, which is the whole point of the prefix — every military department and defense agency works from one identical document. Looking for a branch variant wastes time you do not have.
Who decides this form exists? not stated owns it; not stated directs its use. If someone told you to file this, the authority traces back to those.
Which edition should you have? not stated, listed as not stated. A copy dated otherwise is a copy worth replacing.
Download the form
Which files are here? These: PDF. How much work is involved? unknown pages, about unknown entry fields.
Fillable or printable — which do you have? Click inside a box. If it accepts a cursor and typed text, the file is fillable and your entries save with it. If nothing happens, the pdf is flat, and the only way forward is printing it and writing on paper.
Does typing matter? It does. Your completed form will probably be scanned, forwarded and filed, and typed text comes through each of those steps unchanged while handwriting degrades. If pen is your only option, block capitals give the receiving clerk a fighting chance.
Where do you start? At the top. Identification first, the substance of the entry second, certification last. Why that order? Because fields lower on the page often depend on data you established in the header, and filling out of sequence produces contradictions.
What if your copy is old? Replace it. Check the date printed on the form against not stated. Old blanks circulate for years in shared folders, and because a DD revision lands across the whole Department at once, the receiving office will be working from the new layout.
What about a box that does not apply to you? Enter N/A rather than leaving it empty. An empty field reads as an oversight and sends the form back; N/A reads as an answer. What about dates? Use the format printed beside the field, not the one you write by habit.
Why read the Privacy Act Statement? Because it sits ahead of the personal data fields deliberately. It names the collection authority, the principal purpose, the routine uses of your data and the consequence of declining. Reading it afterward tells you nothing you can still act on.
How do you sign electronically? With a digital signature, usually CAC-based, in a reader that handles it. Will typing your name work? Not as execution — it fills a field without certifying anything. Either way, the date goes in immediately after.
What goes wrong most? The same short list: old edition, empty fields, illegibility, wrong date format, missing signature or date.
Where do you look up an unclear entry? The form face first, not stated second. And when the two disagree? not stated controls.
Who receives it? The office not stated designates, subject to whatever local instruction your organization adds. What do you keep? A copy, made before the form leaves your hands.
Do you need to know which branch issued a related form? No. DD numbering is Department-wide and unified, which means the number on its own is a complete address for the document.
Why do some instructions cite both a DA and a DD form? Because the procedure touches both systems, not because the forms are related. Service forms answer to a service proponent; DD forms answer to not stated or another Department office. The sequences were never aligned.
How often does a form like this change? Unpredictably — revision follows directive changes, altered collection requirements and updated notice language. What is the practical defence? Verifying not stated every time you download rather than trusting a saved copy.
Will your completed form be accepted? That is not a question this page can answer. What you have here is a published Department of Defense document, a description of it and instructions for filling it out. Nothing on the page is legal advice, and nothing here determines what any office does with a submission. Where do the remaining questions go? To not stated, to your servicing personnel office, or to the office named in not stated.
