What is a key verification step if there are suspicions about an ID's authenticity?

The correct choice is to ask for a second form of ID when there are suspicions about the authenticity of an ID. This step is crucial in verifying the identity of the individual attempting to purchase alcohol or enter a licensed establishment. A second form of ID can provide additional information that corroborates the identity presented on the initial ID.

By requesting a second form of identification, you can cross-check names, dates of birth, photographs, and other identifying information, which can help confirm whether the individual is who they claim to be. This practice helps to ensure compliance with laws regarding age verification and helps to prevent underage drinking and identity fraud.

While other options, like checking for personal use notes or looking for self-adhesive labels, might suggest that an ID is altered or counterfeit, they do not provide robust confirmation of authenticity. Contacting law enforcement might be a consideration in specific scenarios, but it is typically not the immediate response when handling an ID verification issue. Instead, gathering more evidence through a second form of ID is a straightforward and effective method for addressing such suspicions.
