Some states have laws (statutes) that require a person to accurately provide their identification (ID) (name, residence address, date of birth) to the police if the police have reasonable suspicion to believe (1) a crime has been committed, is being committed, or is about to be committed and (2) the person asked to provide identification is involved as a participant or as a witness. If there is no reasonable suspicion, a person does not have to provide identification—but courts often find reasonable suspicion as a matter of course.

These statutes are sometimes called stop-and-identify laws or stop and ID laws, and the violation of the statute may be a criminal offense or crime known as “failure to ID.” Stop and ID laws vary from state to state in the states that have such laws. For example, in some states failure to ID cannot be the basis for an arrest (there must be an underlying criminal offense) and in some states the obligation to provide identification only applies to a person who has been arrested.

And in some states it is a criminal offense for a person to provide a false or fictitious name, residence address, or date of birth if the person has been detained by police on the basis of reasonable suspicion or is believed to be a witness to a criminal offense.

The United States Supreme Court has held that the Fifth Amendment to the Constitution may allow suspects to refuse to give their name if they have a reasonable belief their name could be incriminating. Kolender v. Lawson, 461 U.S. 352 (1983).

In Connecticut, there is no specific 'stop and identify' statute that requires individuals to provide their identification to police officers under all circumstances. However, under Connecticut law, if an officer has reasonable suspicion that a person has committed, is committing, or is about to commit a crime, the officer may detain that person for a reasonable period to investigate. During such a detention, if an officer requests identification, the individual is generally expected to comply. Failure to do so could potentially lead to charges such as interfering with an officer or obstruction of justice. Additionally, providing false information to a police officer is a criminal offense in Connecticut. It's important to note that the Fifth Amendment provides protections against self-incrimination, which means individuals may have the right to refuse to provide their name if they reasonably believe it could be incriminating, in line with the U.S. Supreme Court decision in Kolender v. Lawson.
