Ask HN: What would you easily like to verify about an organization?

Before deciding to transact with an org (company, institution, etc), what claim about it would you easily like to make sure is true? This could be checking about an attribute or that a given request indeed originates from said org.

Examples:

- Provider A does deliveries in country X

- Company B is compliant with standard Y

- Phone call is indeed on behalf of a company Z
