How to Fill Out and Submit SF 312: Classified Information Nondisclosure Agreement

The SF 312 Classified Information Nondisclosure Agreement is the contract you sign before the federal government grants you access to classified national security information. It is short — two pages — but it binds you for life. By signing, you accept a permanent duty to protect classified information from unauthorized disclosure, to report security incidents, and to submit certain future writings for pre-publication review. No signature, no clearance.

What the Agreement Protects

SF 312 covers classified information at every level: Confidential, Secret, and Top Secret. Executive Order 13526 defines those tiers by the degree of harm unauthorized disclosure could cause.¹ The day-to-day handling rules sit in 32 CFR Part 2001.²

Protection is not limited to documents bearing a classification stamp. The agreement also reaches unmarked information that meets the standards for classification, oral communications, and electronic data. If classified information appears in a newspaper or online, you cannot treat it as declassified. It remains classified until an authorized official formally declassifies it.³

One boundary worth flagging: SF 312 covers collateral classified information only. If you need access to Sensitive Compartmented Information, you sign Form 4414 in addition to SF 312, and possibly further agreements for specific SCI categories.⁴

How to Complete and Submit the Form

The current version, revised December 2023, is available from the General Services Administration or your agency’s security office.⁵ You can complete it electronically or on paper.⁶ Page one contains twelve numbered paragraphs setting out the obligations. Page two is where you enter your information.

You fill in three things: your signature and the date, your Social Security number, and your organization. Contractors also list their address and, where applicable, a Federal Supply Code Number.

Two additional signatures complete the form. A witness signs, dates, and provides a name and address to confirm they observed your execution of the agreement. An authorized government representative then signs the acceptance block, formally accepting the agreement on behalf of the United States. For contractors, one authorized representative of the contractor organization may serve as both witness and accepting official.⁶

The bottom of page two includes a Security Debriefing Acknowledgement. Its use is optional at the agency’s discretion; agencies that skip it must maintain an alternative debriefing record.⁶

Signing Options

Three signing methods are permitted, depending on what your agency allows. A wet-ink signature always works. If your agency permits it, you can sign by hand and scan the document, so long as the scan produces a legally enforceable facsimile. Since May 2022, you can also sign digitally using a PIV card or CAC that complies with HSPD-12.⁷

Two shortcuts are specifically prohibited. You cannot use a typed “/s/” signature. You cannot paste in an image of your handwritten signature. Neither meets the authenticity requirement.⁶

Where the Signed Form Goes

Once all three signatures are in place, the form goes to your agency’s security office. Defense Department contractors have theirs uploaded into the Defense Information System for Security (DISS). Government employees may have theirs placed in their Official Personnel Folder or an equivalent centralized security database. The government retains the original indefinitely. Ask your security office for a copy for your own records — you are entitled to one, and it is a useful reference for the commitments you have made.

Refusing to Sign

Signing is not optional if you want access. The regulation states that execution of SF 312 is a prerequisite to being granted access, with the sole exception of a national security emergency as defined in Section 4.2(b) of Executive Order 13526.⁶ If your position requires a clearance and you refuse, you do not get access, which in practice means you cannot perform the job.

What You Are Agreeing To

The twelve paragraphs on page one create specific, enforceable duties that take effect the moment you sign.

Never Disclose Without Verifying

You agree never to share classified information with anyone unless you have officially verified that the recipient has proper authorization from the U.S. government, or you have received prior written notice from the classifying agency that the disclosure is permitted. If you are unsure whether something is classified, you must confirm its status with an authorized official before discussing it with anyone who is not cleared.⁵

The liability standard is practical rather than strict. You can be held responsible for disclosure only if you knew or reasonably should have known that the information was classified and that your action would or could result in unauthorized disclosure.³

Report Security Incidents

If you become aware that classified information has been lost, stolen, or disclosed to someone unauthorized, you must report it promptly to your security officer. Staying quiet about a known compromise is itself a violation: 18 U.S.C. § 793(f) makes it a crime to fail to report the loss or theft of national defense information. The duty extends to attempted solicitations, so if someone without access tries to pry classified information from you, that also goes to your security officer.³

Challenge Questionable Classifications

The agreement expects you to challenge classification decisions you believe are wrong. If you hold information in good faith and think its classification level is improper — either over-classified or under-classified — you are encouraged to raise the issue through your agency’s formal challenge procedures.³

Pre-publication Review

One obligation catches many signers off guard. By signing SF 312, you accept responsibility for complying with all applicable pre-publication review policies.⁵ In practice, if you write a book, article, op-ed, academic paper, or any material that a reasonable person might think contains or derives from classified information, you must submit it for review before publication. The submission goes to your agency, or to the last agency that granted you access. Review timelines vary by agency, but the obligation to submit is universal for SF 312 signers, and it continues after you leave government service.

How Long the Agreement Lasts

SF 312 is a lifetime commitment. The form states that all obligations apply during the time you hold access and “at all times thereafter,” unless you receive a written release from an authorized government representative.⁵ Written releases are extraordinarily rare. Retirement, resignation, termination, or revocation of your clearance does not end the agreement.⁸ The pre-publication review obligation follows you into the private sector, which affects former officials who write memoirs, consult for media, or give speeches touching on their government work.

Whistleblowing Is Still Available

Signing SF 312 does not strip you of the right to report fraud, waste, or abuse through proper channels. The Intelligence Community Whistleblower Protection Act gives intelligence community employees a way to report “urgent concerns” to Congress — defined as serious problems, abuses, or violations of law related to intelligence activities — without facing reprisal.⁹

Presidential Policy Directive 19 adds protection for employees and contractors with clearances, prohibiting agencies from retaliating against someone who makes a lawful whistleblower disclosure, including retaliation through the security clearance process. Complaints go first to your agency’s inspector general. After exhausting internal review, you can seek external review from the Inspector General of the Intelligence Community.¹⁰

The critical distinction is the channel. These protections cover disclosures made through authorized channels (inspectors general, designated congressional committees) following established procedures. Going to the press or posting on social media is not a protected disclosure, no matter how legitimate the underlying concern.

Consequences for Violating the Agreement

Penalties stack across administrative, civil, and criminal tracks, and all three can apply to the same incident.

Administratively, the immediate consequence is usually loss of clearance and termination. Agencies do not need a criminal conviction to pull your access; an administrative finding that you violated the agreement is enough. Because clearance is a condition of employment for most cleared positions, losing it means losing the job.

Civilly, because SF 312 is a contract, the government can sue for breach. This is the mechanism used to recover profits from unauthorized publications. If you write a book using classified information without submitting it for pre-publication review, the government can claim your royalties.

Criminally, several federal statutes apply. The most commonly invoked is 18 U.S.C. § 793, part of the Espionage Act, which criminalizes willfully communicating national defense information to unauthorized persons and carries up to ten years in prison.¹¹ Section 798 targets disclosure of classified information related to communications intelligence and cryptographic systems, also up to ten years, with mandatory forfeiture of any proceeds.¹² Fines follow the general federal fine statute, 18 U.S.C. § 3571, with a maximum of $250,000 for any individual convicted of a felony.¹³ Failing to report the loss or theft of classified material — as opposed to actively leaking it — can also be prosecuted under § 793(f), with the same ten-year maximum.³
