Which of the following options is included in acceptable forms of ID for purchasing SLCPs?

When it comes to the regulations surrounding the purchase of Scheduled Listed Chemical Products (SLCPs), the DEA outlines acceptable forms of identification. The correct option, which is the US Coast Guard Mariner Card, serves as a valid form of ID because it is a government-issued identification that includes the person's name and a photograph.

Government-issued IDs are typically required in these situations to ensure that the purchaser can be accurately identified and that they meet the legal requirements for purchasing SLCPs, which are regulated due to their potential use in manufacturing illegal drugs.

In contrast, the other options—such as library cards, health insurance cards, and membership cards—do not carry the same level of authority as they are not issued by a government agency. They lack critical features like a photograph or official verification of identity that are necessary for such regulated purchases. Therefore, the US Coast Guard Mariner Card is recognized as an acceptable form of identification due to its status as a legitimate government-issued document.
