DD Form 2490-31 occupies a particular place in Defense recordkeeping. Its title is DD 2490-31, Network Planning and Configuration Data - NNXX Routing Worksheet. This form has not been set up to work with a text-to-speech reader. Contact the DoD Forms Manager for further details if this access is required., and it exists to Network Planning and Configuration Data - NNXX Routing Worksheet. What the DD prefix records is an administrative judgment made long before your copy was printed: this transaction was determined to be common to the whole Department rather than peculiar to one service, and so the documentation of it was standardized at Department level.
The practical effect of Department-level issue is interoperability. not stated establishes the requirement across the Defense enterprise; not stated keeps the document current for all of it. No service maintains its own variant, which means a completed record travels between components — service to agency, agency to joint command — and arrives in a format the receiving office already knows how to read.
You are looking for edition not stated, listed as not stated. Department-wide supersession is a single event rather than a rollout, which is what distinguishes edition currency on a DD form from the same question on a service publication: nobody anywhere is still accepting the previous version out of habit.
The form is laid out top to bottom in a sequence that reflects how the record will be read, not merely how it was drawn. Identification comes first because everything below it is understood in relation to a named person, unit or transaction; substantive entries follow; certification closes the document because certification attests to what precedes it. Filling out of order tends to produce internal inconsistencies — an entry that made sense before the header was settled and does not afterward.
Check the edition date before you type anything, against not stated. Old blanks accumulate in shared drives for years, and the cost of one is not obvious until a reviewer cannot find a field. Because DD forms are revised centrally and replaced across the Department in a single action, there is no component still tolerating the old layout as a local practice.
For an ambiguous field, read the form's own instruction, then not stated, which controls.
Download the form
The set published here is PDF, covering 1 pages with roughly 200 fields. More than one format survives because the Department serves users under very different conditions, from a desk with current software to a location where a printer is the only reliable output.
The difference between a fillable and a printable pdf is a difference in what the file contains. A fillable release carries an interactive layer: each box is a defined field with a name and a data type, and what you type is stored as data inside the document. A printable release has no such layer — it is an image of the page, and the only place your answers can go is onto paper. The distinction matters downstream, because a Department record often gets scanned and forwarded several times before it reaches its final file, and typed characters survive that chain in a way pen strokes do not.
If you find an xfdl file here, its presence is historical. The format belongs to IBM Lotus Forms, which the Department adopted Department-wide for electronic forms and fielded on a scale that makes wholesale removal slow. You need the matching viewer to open it; ordinary pdf software cannot read the format and will say so unhelpfully.
Every format is free, as published government documents are. A note on tools, though — the interactive field layer that makes a fillable pdf useful is precisely the part browser viewers handle least reliably. Save the file, open it in a full pdf reader, and the fields behave as the form's designer intended.
What the form asks for

The completed form goes to the office named in not stated or in local implementing procedure, and it is worth keeping a copy before it goes. On a Department form the destination is frequently outside your own chain — another service, a defense agency, a joint staff — and recovering a document that has crossed an organizational boundary is a slower business than retrieving one from a file down the hall.
When DD Form 2490-31 cites another form, the citation is self-sufficient. The DD series is a single sequence administered at Department level, so the number resolves to exactly one document without any need to establish which component issued it — a convenience that exists only because the sequence was never allowed to fork.
Procedures that touch both Department and service processes will cite forms from both sequences, and the coincidence of numbers between them is exactly that — coincidence. An Army proponent maintains the DA series for the Army; not stated or another Department office maintains the DD series for the whole Department. Two independent registries, two independent numbering runs, no correspondence at any value.
Understanding why editions change explains why checking them is not optional. Revision follows directive reissue, changes in what data is required, and amendments to mandatory notice text — decisions made at Department level and communicated through publication rather than notification. The file you saved does not update itself, so the edition date at download is what you rely on.
The role of this page is narrow and worth stating plainly. It makes a published Defense form available and explains its structure. It does not advise, does not interpret policy for your circumstances, and cannot indicate how any office will treat a completed copy — those judgments rest with the authorities that own the process. Direct such questions to not stated, to the administrative office that services you, or to the authority named in not stated.
