You have arrived looking for DD Form 2490-40. Before you download, confirm this is the right document: Network Planning and Configuration Data - Call Inhibit Lists Worksheet. Full title: Network Planning and Configuration Data - Call Inhibit Lists Worksheet.
Next, check the edition. You want not stated, currently carried as not stated by the publisher. Then confirm the form applies to you — this is a Department of Defense form, so you use it whether you serve in the Army, Navy, Air Force, Marine Corps, Space Force or Coast Guard under Defense jurisdiction.
Then settle the schedule. You are working under not stated, with not stated responsible for the document, and your organization layers its own deadlines on that. Ask before you assume a date.
Last in this stage, choose your method: complete it on screen, or print the blank form and fill it out in pen. The sections below take each route step by step.
Now fill it in. Work from the top of the page downward, and do not jump ahead — the identifying block comes first, the substance of your entry second, the certification last. Later boxes often depend on what you put at the top.
Your first action is verification. Find the edition date on the form and match it against not stated. A mismatch means you are working from a superseded printing, and because DD forms change Department-wide rather than service by service, the office receiving it will notice.
Take the fields in order and answer all of them. Mark inapplicable items N/A instead of leaving white space. When you reach a date, copy the format shown on the form, since a reviewer reading a different convention may misread your entry entirely.
Do not skip past the Privacy Act Statement. It is placed ahead of the personal data fields on purpose: it explains under what authority you are being asked, what happens to the information, and what follows if you decline. Take the minute it costs.
Sign last, and sign properly. On paper that means ink in the signature block. Electronically it means a digital signature, usually applied with your Common Access Card in a reader that supports it. Typing your name into the field does not sign anything. Then add the date beside your signature — an unsigned or undated form is the most common reason one comes back.
Then check your work against the usual failures: an obsolete edition, empty required boxes, handwriting nobody can read after scanning, wrong date format, missing signature or date.
Look up an unclear item on the form face before anywhere else, then in not stated. Should the two texts conflict, the directive is the one you follow.
Download the form
First, look at what you can download. The set covers PDF, the form runs 1 pages, and you will complete roughly 200 fields.
Take the pdf if you are unsure. Then check which kind you have: if the boxes highlight when you click them, you have a fillable pdf and can type straight into it, and your entries save with the file. If nothing highlights, you have a printable pdf — send it to a printer and use black ink.
Type when you can. Printed entries stay legible after the form is scanned, copied and forwarded, and handwriting often does not survive that trip. If you must write by hand, use block capitals and press firmly.
Handle xfdl in two steps. First confirm you have IBM Lotus Forms Viewer or a compatible reader on your machine; ordinary pdf software will report the file as broken. Once the viewer is running, download and fill the form.
Whichever you pick, you pay nothing — every format here is a free download. One last tip: open your pdf in a desktop reader rather than in a browser tab, because browser viewers sometimes drop the interactive fields you need.

Now that it is complete, send it where not stated or your local procedure says it goes. Before you do, make yourself a copy — scan it or save the file elsewhere. It costs you nothing and saves you the whole exercise if the original goes missing.
Should you need a related form, look it up by its number. The DD sequence is Department-wide, which makes your search simple: no service qualifier, no branch-specific variant to track down.
Be careful when a procedure pairs this form with a service form. Read the prefix, not just the digits. Service forms answer to a service proponent, while DD forms answer to not stated or an equivalent Department office, and the two sequences were never aligned. Grabbing the wrong prefix gets you a form that has nothing to do with your task.
Do not archive this file and reuse it in a year. Forms are reissued as directives are revised, as data requirements shift, and as statutory notice text is amended. Your protection is simple: download fresh each time and confirm the edition date.
Finally, understand the limits of what you have read. This page distributes a published Department of Defense form and describes how to fill it out. It does not give legal or procedural advice, and it cannot promise any outcome for your particular case. For that, contact not stated, your administrative office, or the authority identified in not stated.
