Under 18 USC 912, it is a federal felony to falsely claim to be an officer or employee of the United States and then either act in that assumed role or use the pretense to demand or obtain money, papers, documents, or anything of value. A conviction carries up to three years in federal prison and a fine of up to $250,000.1Office of the Law Revision Counsel. 18 USC 912 – Officer or Employee of the United States2Office of the Law Revision Counsel. 18 U.S. Code 3571 – Sentence of Fine
The Two Ways to Violate the Statute
Section 912 sets out two independent offenses, and the government only has to prove one. The first covers anyone who falsely assumes or pretends to be a federal officer or employee and then “acts as such.” The second covers anyone who, in the pretended character, demands or obtains money, papers, documents, or anything of value.1Office of the Law Revision Counsel. 18 USC 912 – Officer or Employee of the United States
A common misreading is that both prongs require an intent to defraud. They don’t. In United States v. Lepowitch, the Supreme Court held that the first prong does not require the government to prove the defendant intended to obtain anything of value or cause a financial loss. The absence of “thing of value” language in the first clause was deliberate. The Court framed the statute as protecting “the general good repute and dignity” of federal service, which means prosecutors don’t have to show anyone was actually fooled or that measurable harm occurred.3U.S. Reports. United States v. Lepowitch, 318 U.S. 702 (1943)
What “Acting as Such” Actually Requires
Telling someone “I’m with the FBI” is not, by itself, a Section 912 violation. The statute requires that the false claim be paired with conduct: the person must do something that a real federal officer would do, something that exercises or trades on the pretended authority. That conduct requirement is where most of the case law lives.
In United States v. Harmon, the defendant told people he was an FBI agent and then interrogated them. The Second Circuit treated the interrogation itself as the critical conduct.4Justia Law. United States v. Harmon, 496 F.2d 20 (2d Cir. 1974) In United States v. Rosser, wearing a U.S. Marshal badge and attempting to detain someone was enough.5Justia Law. United States v. Rosser, 528 F.2d 652 (D.C. Cir. 1976) The conduct doesn’t need to be dramatic. In United States v. Guthrie, the defendant wore a U.S. Army uniform and attended official functions, letting people believe he held military authority. No interrogation, no attempted arrest. The Fourth Circuit held that showing up in uniform and participating was enough.6Justia Law. United States v. Guthrie, 387 F.2d 569 (4th Cir. 1967)
The medium doesn’t matter either. Someone calling victims while posing as an IRS agent and demanding payment, or emailing targets as a federal investigator to pull personal information, is both assuming the identity and acting in it. What matters is whether the false claim was followed by conduct a real federal employee would perform.
Penalties and How Sentences Get Calculated
A Section 912 conviction is a Class E felony. The statutory maximum is three years in federal prison and a fine up to $250,000.1Office of the Law Revision Counsel. 18 USC 912 – Officer or Employee of the United States2Office of the Law Revision Counsel. 18 U.S. Code 3571 – Sentence of Fine Courts can also order restitution when victims suffered financial losses and impose up to one year of supervised release after prison.7Office of the Law Revision Counsel. 18 U.S. Code 3583 – Inclusion of a Term of Supervised Release After Imprisonment
Actual sentences, though, are driven by the U.S. Sentencing Guidelines more than by the statutory ceiling. The base offense level for impersonation under Guideline Section 2J1.4 is 6, which for a first-time offender with no criminal history translates to a recommended range of zero to six months. If the impersonation was carried out to conduct an unlawful arrest, detention, or search, a six-level enhancement applies and roughly doubles the recommended range.8United States Sentencing Commission. Guidelines Manual (November 1, 2025) – Chapter 2, Parts E-K
The bigger risk is a cross-reference in the guidelines. If the impersonation facilitated another crime such as fraud, extortion, or identity theft, the judge applies whichever guideline produces the higher offense level. That means an impersonation count can effectively be sentenced at the level of the underlying crime, which may carry a far longer recommended range than the base level of 6.
Consequences That Outlast the Sentence
A federal felony conviction under Section 912 creates permanent barriers that survive any prison term.
- Firearms possession. Anyone convicted of a crime punishable by more than one year in prison is permanently barred from possessing firearms or ammunition under federal law, and a Section 912 conviction triggers that ban.9Bureau of Alcohol, Tobacco, Firearms and Explosives. Identify Prohibited Persons
- Federal employment and clearances. A felony conviction is an automatic disqualifier for many federal positions. The FBI, for instance, treats any felony conviction as a permanent bar to employment as a special agent, and obtaining a security clearance after a federal impersonation conviction is effectively impossible.10FBI Jobs. Employment Eligibility
- Professional licensing. State boards for law, medicine, finance, and other regulated fields require disclosure of felony convictions and may deny or revoke licenses based on convictions involving dishonesty.
- Immigration status. Non-citizens convicted of a federal felony involving fraud or deceit face potential deportation, denial of naturalization, and bars to reentry.
Defenses That Have Traction
Each element of a Section 912 charge is a potential weak point. The government must prove beyond a reasonable doubt that the defendant knowingly claimed federal identity and either acted in that role or used it to obtain something.
No Conduct Beyond the Words
The strongest defense in many cases is that the defendant never acted on the false claim. Bragging to a neighbor at a barbecue about a fake CIA job, without more, does not satisfy the statute. If prosecutors can’t identify specific actions the defendant took while posing as a federal official, the first prong has a structural problem.
No Knowing Misrepresentation
The defendant must have knowingly claimed a federal identity. Wearing surplus clothing with unfamiliar patches, or genuine confusion about whether a contractor or grantee role carries federal authority, can undercut the knowledge element.
Parody or Satire
First Amendment protections can apply when the alleged impersonation was clearly comedic or theatrical. A “FBI” Halloween costume is protected expression. Courts ask whether a reasonable person would believe the defendant was genuinely asserting federal authority. If the pretense was used to gain access, extract information, or intimidate someone, the parody framing collapses.
Insufficient Evidence
These cases often turn on witness testimony, surveillance footage, and physical items like fake badges or credentials. Contradictory accounts, unreliable witnesses, or evidence obtained through an improper search all give the defense room to challenge whether the government has met its burden, especially in cases built on a brief encounter reported by one person.
Statute of Limitations
The government has five years from the date of the offense to bring charges. That’s the general federal limitations period for non-capital offenses under 18 USC 3282, and Section 912 has no special extension.11Office of the Law Revision Counsel. 18 U.S. Code 3282 – Offenses Not Capital For an ongoing scheme, the clock runs from the last act of impersonation, not the first.
Related Statutes Prosecutors Often Add
Section 912 rarely stands alone. Several other federal statutes reach related conduct, and charges are frequently stacked.
Section 913 targets a specific and more dangerous form of impersonation: pretending to be a federal official and then arresting, detaining, or searching someone. The statutory maximum matches Section 912 at three years, but the sentencing guidelines treat this conduct more seriously through the six-level enhancement noted above.12Office of the Law Revision Counsel. 18 U.S. Code 913 – Impersonator Making Arrest or Search
Section 701 makes it a misdemeanor to manufacture, sell, or possess any federal badge, identification card, or convincing imitation without authorization, punishable by up to six months.13Office of the Law Revision Counsel. 18 USC 701 – Official Badges, Identification Cards, Other Insignia Section 702 makes it a misdemeanor to wear the uniform of any branch of the armed forces or the Public Health Service without authority, also carrying a six-month maximum.14Office of the Law Revision Counsel. 18 USC 702 – Uniform of Armed Forces and Public Health Service A person caught displaying a fake DEA badge at a traffic stop often faces both a Section 912 felony and a Section 701 misdemeanor.
When the conduct involves producing or holding fake federal identification documents, 18 USC 1028 comes into play. Penalties there are far steeper: up to 15 years for producing or transferring false federal IDs, and up to 30 years if the fraud facilitated an act of terrorism.15Office of the Law Revision Counsel. 18 U.S. Code 1028 – Fraud and Related Activity in Connection With Identification Documents, Authentication Features, and Information
