I was curious about this so I looked it up. Here are the states that do not require one to identify.

Alaska, California, Connecticut, Hawaii, Idaho, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, New Jersey, North Carolina, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Virginia, Washington, West Virginia, Wyoming, plus Washington D.C.

and then

- You must be detained on reasonable suspicion; a casual chat (“consensual encounter”) never triggers the duty.

- Verbal name only—no law forces you to carry or hand over a card.

- Driving is separate—every state requires a license on traffic stops.

- Lying is illegal everywhere (false ID to police is usually a misdemeanor).

- Filming police is protected nationwide; identifying yourself is unrelated.
