So what is DD Form 2490-40? The short answer: a Defense Department document, officially Network Planning and Configuration Data - Call Inhibit Lists Worksheet, used to Network Planning and Configuration Data - Call Inhibit Lists Worksheet. Anything else you need follows from that.
Does it apply to your branch? Yes. The DD prefix means Department of Defense, not one service, so the same blank serves the Army, Navy, Air Force, Marine Corps, Space Force and the Coast Guard under Defense jurisdiction. There is no Army version and no Navy version to search for.
Who is behind it? not stated maintains the form, and not stated is the publication that requires it. Those two names answer most questions about why you are being asked to submit anything at all.
How current is this? Edition not stated, publisher status not stated. That is the version described throughout this page.

Download the form
What can you download? The available set is PDF. How big is the job? The form runs 1 pages with roughly 200 fields to complete.
What does any of this cost? Nothing. Every format listed is a free download. One practical note: save the file and open it in a desktop pdf reader, because browser previews often ignore interactive fields and lose what you typed.
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.
Can you leave fields blank? Not safely. A reviewer cannot tell a deliberate omission from a missed question, so mark inapplicable items N/A. And date fields? Match the format shown on the form — conventions differ, and misreading a date is easy.
What is the Privacy Act Statement doing on the form? Telling you, before you supply personal identifiers, under what authority the information is collected, what it will be used for, who else may see it, and whether answering is voluntary or mandatory. Is it worth reading? It is the only part of the form written for your benefit rather than the file's.
Is a typed name enough? No. The signature block takes an actual signature: pen on paper, or a digital signature applied with your Common Access Card where the receiving system accepts one. Add the date beside it before you close the file.
What sends forms back most often? An obsolete edition, blank required boxes, handwriting illegible after scanning, dates in a format the form did not ask for, and certification without a signature or without a date.
Where do you look up an unclear entry? The form face first, not stated second. And when the two disagree? not stated controls.
Where does the completed form go? To the office named in not stated or in your organization's local procedure. Should you keep a copy? Always — a scan or a saved file costs nothing and spares you the whole exercise if the original disappears.
What if DD Form 2490-40 points to another form? Search the series and number. Because the DD sequence is common to every military department, no branch qualifier is needed to land on the right file.
Can you assume a matching number is the same form? No, and this is where downloads go wrong. Read the prefix. Army numbering and Department numbering are independent systems, so the digits alone tell you nothing about which document you need.
Why do editions change at all? Three reasons, mostly: the prescribing directive gets reissued, the information collected changes, or the required notice language is amended. Are you notified when it happens? No. Which is why confirming not stated at the moment you download is worth the few seconds.
Is any of this advice? No. This page distributes a published Defense form and explains its contents, which is a different thing from telling you whether your circumstances qualify or whether a reviewer will accept your copy. Direct questions of eligibility, applicability and procedure to not stated, to your servicing personnel office, or to the office designated in not stated.
