DD Form 2490-40 is a Department of Defense form, not a service form: Network Planning and Configuration Data - Call Inhibit Lists Worksheet, used to Network Planning and Configuration Data - Call Inhibit Lists Worksheet. 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.
The set is PDF. Size: 1 pages, about 200 fields. Everything below refines that choice.
Take the fillable pdf unless you have a reason not to. Fillable means the boxes are real fields that accept typed text and retain it in the file. Printable means a flat blank — no fields, printer and pen only. The difference is not cosmetic: one produces a record that reproduces cleanly through scanning and forwarding, the other depends on penmanship.
What the form asks for
- Press this Reset button to clear the data from all fields.
Verify the edition before the first keystroke. The date on the form face should read not stated. If it does not, discard the file. Field numbering shifts between editions, and on a DD form the new layout reaches every receiving office in every service at once — there is no lag during which the old version is still normal somewhere.
Unclear entries — read the form face, then not stated; the directive prevails.
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.
Related forms are found by number alone. The DD sequence is one unified Department-wide series, so a cited number resolves to exactly one document with no branch qualifier needed.
Prefix before number. A DA citation and a DD citation in the same instruction point at separate systems — one Army, administered by an Army proponent, one Department-wide under not stated — and there is no correspondence between them at any number.
Editions change when the prescribing directive is reissued, when the data collected changes, or when notice language is amended. None of that reaches you. Checking not stated at download is the entire defence, and it is cheaper than repeating a submission.
What is here is the blank form and a description of it. What is not here is legal guidance or any assurance about a particular filing — this page is not the issuing authority and does not speak for one. Those questions go to not stated, to your servicing administrative office, or to the authority identified in not stated.
