Do You Have to Give Your Name to Police?

Few questions about ordinary encounters with the law produce more confident and contradictory answers. Some people are certain that no one ever has to identify himself to police. Others are equally certain that refusing is always a crime. Both answers fail for the same reason: the law depends on what kind of encounter is taking place, where it is taking place, and what exactly is being asked for.

The Supreme Court has addressed the question several times, and the cases, read together, describe a framework rather than a yes-or-no rule. This entry explains that framework; it is not guidance for any particular encounter.

Three kinds of encounter

Fourth Amendment law distinguishes, broadly, among consensual encounters, investigative detentions and arrests.

A consensual encounter occurs when police approach and ask questions without restraining the person. The Court held in INS v. Delgado, 466 U.S. 210 (1984), that "interrogation relating to one's identity or a request for identification by the police does not, by itself, constitute a Fourth Amendment seizure." An encounter becomes a seizure only if, in view of all the circumstances, a reasonable person would believe he was not free to leave; or, in confined settings such as a bus, would not feel "free to decline the officers' requests or otherwise terminate the encounter" (Florida v. Bostick, 501 U.S. 429 (1991)). Police may ask for a name in such an encounter. The cases do not hold that a person must answer.

An investigative detention, often called a Terry stop after Terry v. Ohio, 392 U.S. 1 (1968), is a brief seizure based on reasonable suspicion that the person is involved in criminal activity. It requires less than the probable cause needed for arrest but more than a hunch.

An arrest requires probable cause and leads to booking and other procedures in which identity is routinely established. The archive's entry on what happens after arrest describes that stage.

Brown v. Texas: no suspicion, no duty

In Brown v. Texas, 443 U.S. 47 (1979), El Paso officers stopped a man walking in an alley in an area known for drug activity, and he was convicted under a Texas statute making it a crime to refuse to give a name and address to an officer who had lawfully stopped him. The Court unanimously reversed. It held that the officers lacked "a reasonable suspicion, based on objective facts, that the individual is involved in criminal activity," so the stop itself violated the Fourth Amendment. The Court expressly reserved the larger question: "We need not decide whether an individual may be punished for refusing to identify himself in the context of a lawful investigatory stop which satisfies Fourth Amendment requirements."

Kolender v. Lawson: "credible and reliable" identification

In Kolender v. Lawson, 461 U.S. 352 (1983), the Court considered a California statute that required persons who loiter or wander on the streets to provide "credible and reliable" identification when stopped under Terry circumstances. The Court held the statute unconstitutionally vague under the Due Process Clause because it gave no standard for what a person had to do to satisfy the requirement, vesting "virtually complete discretion in the hands of the police." Kolender did not decide whether a state may require a name; it decided that this particular requirement was too indefinite.

Hiibel: a name, during a lawful stop

The reserved question was answered in Hiibel v. Sixth Judicial District Court of Nevada, 542 U.S. 177 (2004). A Nevada deputy, investigating a report of an assault involving a truck, found Larry Hiibel standing beside a parked truck matching the description. Asked for identification eleven times, Hiibel refused each time and was convicted of obstructing an officer under Nevada law. The relevant Nevada statute, quoted by the Court, provides that an officer may detain a person "under circumstances which reasonably indicate that the person has committed, is committing or is about to commit a crime," and that "any person so detained shall identify himself, but may not be compelled to answer any other inquiry."

The Court, in an opinion by Justice Kennedy, held that "the principles of Terry permit a State to require a suspect to disclose his name in the course of a Terry stop." It also rejected Hiibel's Fifth Amendment claim on the facts, finding no reasonable belief that disclosing his name would incriminate him, while leaving open that "a case may arise where there is a substantial allegation that furnishing identity at the time of a stop would have given the police a link in the chain of evidence needed to convict the individual of a separate offense." Justice Stevens dissented, and Justice Breyer, joined by Justices Souter and Ginsburg, dissented separately.

Three limits in Hiibel are frequently lost in retelling. First, the Court understood the Nevada statute to require only a name: "the statute does not require a suspect to give the officer a driver's license or any other document." Second, the requirement applied only during a stop already justified by reasonable suspicion. Third, the Court stated that "an officer may not arrest a suspect for failure to identify himself if the request for identification is not reasonably related to the circumstances justifying the stop."

Stop-and-identify laws vary

Hiibel did not create a nationwide duty to give a name. It held that a state may impose one in the context of a lawful Terry stop. The Court noted that such statutes "vary from State to State," some modeled on the Uniform Arrest Act and others on the Model Penal Code, and that many states have none. Where there is no statute imposing a duty, the question of whether refusing to give a name has legal consequences depends on other state law, such as obstruction statutes, which differ in scope and interpretation.

Drivers are a separate case

A person driving a vehicle stands in a different position, because driving is generally licensed. In Delaware v. Prouse, 440 U.S. 648 (1979), the Court held that police may not stop a car at random merely to check the driver's license and registration; a stop requires "at least articulable and reasonable suspicion" of a violation, though the Court allowed for less intrusive methods such as roadblock-type stops of all traffic. Once a driver is lawfully stopped, state motor-vehicle law commonly requires the driver to have and display a license. California's Vehicle Code, as one example, requires a licensee to have the license "in his or her immediate possession at all times when driving a motor vehicle upon a highway" (Cal. Veh. Code §12951(a)). Those requirements attach to the activity of driving and differ from the rules governing a pedestrian.

What the record supports

Police may ask anyone for a name. In a consensual encounter, the Supreme Court cases do not require an answer. In a detention unsupported by reasonable suspicion, a state may not punish a refusal (Brown). A state may require a person lawfully detained on reasonable suspicion to state his name, at least where the request is reasonably related to the stop (Hiibel), but a vague requirement to produce "credible and reliable" identification is unconstitutional (Kolender). Requirements to produce documents, and the distinct rules for drivers, depend on state law. Whether any of these conditions is met in a particular encounter turns on facts that are often disputed, and is ultimately for courts to decide.
