Start here if you have been told to submit DD Form 2490-1. First, know what you are filling: Network Planning and Configuration Data - Subscriber List. The document is titled Network Planning and Configuration Data - Subscriber List.
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.
After that, turn to timing. The requirement comes from not stated; the form is maintained by not stated. Local implementing instructions fill in the dates, so check with the office that will receive your copy.
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.
Before your first entry, look at the corner of the page and compare the printed date with not stated. If they do not match, stop and download again. Old copies circulate in shared drives for years, and a DD form is revised centrally for every service at once, so a superseded blank may not carry the fields your reviewer expects.
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
Begin by choosing a file. Available here: PDF. Plan for 1 pages and about unknown entries.
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.
Go with the typed route whenever the choice is yours. Consider what happens after you submit: the copy gets scanned, forwarded and filed, and each pass costs handwriting some legibility. Block letters help if you are stuck with a pen.
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.
You will not be charged for any of these; the whole set is free. Before you start entering data, save the file to your computer and open it there. Fields behave far more reliably in a desktop reader than in a browser preview.
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.
One thing this page does not do: tell you whether your submission will be accepted. We publish the document and explain how to complete it, and that is where our role ends. Nothing here is legal advice. Take questions about eligibility, applicability or procedure to not stated, to your servicing personnel office, or to the office named in not stated.
