Which of the following is a requirement for proving identity in Utah?

A valid, unexpired passport is a recognized form of identification in Utah, serving as a primary document to verify identity. This is because a passport includes essential information such as your name, photograph, and date of birth, which are critical for identity verification in various situations, including when applying for a driver’s license.

In comparison, while a certificate of completion from a driving school might prove that an individual has completed necessary training for driving, it does not serve as an official document for identity verification. A letter from a friend also lacks the necessary official status and credibility to prove identity. Therefore, the passport stands out as the correct choice because it meets the legal criteria for identity documentation.
