You need DA Form 7770, and this page gets you to the file and through it. Start with what the form is: CERTIFICATE OF SANITIZATION, used to certificate of sanitization. Check next that you have the right version — the edition dated 02/01/2023 is the one published here, and its status is ACTIVE. Then look at the size before you begin, because 1 page(s) and roughly 135 fields tell you how long this will take. Before you go further, note that a newer edition exists. Use this one only if you are looking at a record already completed on it.
Now decide who does the writing. Normally you enter your own particulars, then hand the sheet to the unit administrative office for review. If you work in that office, you enter what the individual brings you. From there the path is the same for everyone: G-6 is responsible for the form, and PAM 25-2-8 tells you what triggers it and where it ends up. Look at the directive first whenever your case departs from the ordinary.
Begin with the first block and follow the printed order. You will enter your name first, exactly as your official records show it, followed by your identification number, your organisation, and the date of preparation. Resist the urge to jump to the substantive blocks and return to the header later. Those first entries are the index for the whole record, and an error there costs you the ability to retrieve it.
In the body of the form, tab from field to field instead of clicking around. The tab order follows how the form was constructed, which keeps you from missing a box. For check boxes and option buttons, click them. If you find a set where the choices are exclusive, expect your new selection to clear the previous one. Keep an eye on long entries as you type: fields built for one line will not wrap, and what overflows the width will print truncated even though your screen shows all of it. At that point move the text into remarks or onto a continuation. And when something does not apply to you, say so in the field — write the entry that means "none" rather than leaving white space a reviewer has to interpret.
Save the signature for last. Sign by hand, or by whatever electronic method your office accepts, and understand that until you do the document is a draft no matter how complete it looks. If the form calls for a reviewing official, an approving authority, or a witness, take those signatures in the order the blocks print, and have each signer date it on the day they sign rather than the day you prepared it. Before you hand it over, read it once more from the top. You are looking for three things in particular: a mandatory field you left empty, digits transposed in your identification number, and a date written with day and month the wrong way round. Check one more thing if you built this form from a copy you had lying around — old entries survive in a reused file, and they will go forward as though you meant them.
Read the Privacy Act statement when it appears on the page, before you fill in the personal details it covers. It sets out the authority for collecting the information, the purpose behind it, the routine uses it may be put to, and whether your disclosure is required or voluntary. Then keep in mind what you have created — a completed copy carries personal data, and you handle and store it under the rules that apply to such records.
Download the form
Now pick your file. You have PDF to choose from, and the choice depends on one thing: whether you will type the entries or write them by hand. Choose the fillable pdf when you want to type, tab between fields and keep a clean copy on your computer. Choose the printable pdf when you intend to print the blank first and write on paper. The pages look identical either way, so you are not giving anything up by picking the wrong one — you are only choosing how you work.
Once the file is on your machine, open it deliberately. A pdf will usually launch in your browser, which reads well enough but does not always hold what you type; certain viewers display the fields and then discard your entries. Save the download to a folder, open it from there in a dedicated reader, and test one field and one save before you commit to filling the whole thing.
Finally, note what the download costs you: nothing. You do not create an account, you do not enter an email address, and the file you receive is the published document with nothing added to it.

With the form signed, send it where PAM 25-2-8 tells you to send it — usually to the office it names, or through your unit administrative channel, or straight into your own record, depending on why you raised it. Keep a copy for yourself before it leaves your hands. How long the receiving office holds it is not your decision or theirs; the records schedule for the series settles that, and local habit does not override it.
Should the package need more than one document, search by series and number. Within the DA series, forms under the same proponent or the same prescribing directive tend to be required as a set, and a form referenced on the page you are filling usually accompanies it. Collect the continuations, covers and transmittals up front so the submission goes complete the first time.
The next time you open this form from your own files, check the edition date first. Revisions come from the proponent without warning to you, so the only reliable step is to hold your copy against the current edition before filling it in again. Records you already completed under a superseded edition stand, and you do not go back to rework them.
Read this before you go. The file you download is a reproduction of a published Department of the Army document, offered as it was published. We are an independent site with no connection to the Department of the Army and no authority to issue anything, and we make no statement about whether your completed form will be accepted anywhere. Treat what you read here as information, not legal advice. Take real questions — about an entry, a requirement, or your eligibility — to G-6 or to your servicing administrative office.
