<P> `` Stop and identify '' statutes are statutory laws in the United States that authorize police to legally obtain the identification of someone whom they reasonably suspect of having committed a crime . If there is no reasonable suspicion that a crime has been committed , is being committed , or is about to be committed , an individual is not required to provide identification , even in `` Stop and ID '' states . In the case of Utah v. Strieff ( 2016 ) , the U.S. Supreme Court ruled that an officer 's stop of Edward Strieff and his demand for identification from Strieff was unlawful under Utah state law , but that the evidence collected pursuant to the stop was admissible due to the determination that Strieff was subject to a pre-existing arrest warrant . Therefore , the pre-existing warrant `` attenuated '' the unlawful stop - and - identify . </P>
