A variety of supergravity and string based models contain hidden sectors with gauge groups including U(1) which can play important roles in particle physics phenomena and in cosmology. These hidden sectors with U(1) gauge groups can interact feebly with the visible sector and interact feebly or with normal strength with each other. I will discuss in general the U(1) extension of the Standard Model with different types of dark matter candidates.
