DD Form 2490-21 occupies a particular place in Defense recordkeeping. Its title is DD 2490-21, Network Planning and Configuration Data - Digital Loop and Trunk 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 - Digital Loop and Trunk 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.
The edition in force is not stated, carried by the publisher as not stated, and edition discipline is stricter on a Department form than most people expect, precisely because supersession happens everywhere at once. There is no interval during which one service still works from the previous layout while another has moved on.
Work down the page in the printed order, and understand why the order exists. The identifying block establishes whose record this is and under what circumstances it arises. The body of the form then answers questions that are only meaningful once that context is fixed. The signature block comes last because a certification signed before the entries are complete certifies nothing.
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
What you can download: PDF. The form runs 1 pages and asks for approximately 200 entries. The plurality of formats is deliberate: Defense distribution has never been able to assume one operating environment across the whole force.
Fillable and printable are not two presentations of one file but two different objects. One holds your entries as structured data within the document; the other is a static picture meant to meet a pen. Since a DD form frequently moves outside the organization that created it, the durability of the entry matters more here than on a record that stays in one drawer. Typed text reproduces indefinitely; handwriting degrades at every copy.

Submission follows not stated and whatever local instruction supplements it. Make a copy before the original leaves. Department forms travel across organizational lines by design, and the administrative distance that makes them useful is the same distance that makes tracing a lost one difficult.
When DD Form 2490-21 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.
It helps to see the DA and DD sequences as what they are: separate registries with separate custodians. One serves a single service under a service proponent, the other serves the Department under not stated or an equivalent office, and neither was ever indexed against the other. A number that appears in both systems points to two unrelated documents, which is why reading the prefix comes before reading the digits.
A form is downstream of the policy that requires it, and revision usually starts there: a directive is reissued, a collection requirement is altered, notice language is updated by statute. The form is republished as a consequence. Since none of that reaches individual users, an archived copy quietly becomes wrong, and verifying not stated each time you download is the whole remedy.
What you have here is the document and a description of it, which is a different thing from guidance. This page is not an organ of the Department, gives no legal or procedural advice, and makes no representation about the outcome of any filing; the offices that administer the requirement are the only ones positioned to answer that. Applicability, eligibility and procedural questions belong to not stated, to your servicing personnel office, or to the office designated in not stated.
