Sadasivanagar is a village and a Mandal in Nizamabad district in the state of Andhra Pradesh in India. The Administrative divisions of India are Indian subnational administrative units; they compose a nested hierarchy of country subdivisions. Indian states and territories frequently use different local titles for the same level of subdivision (e.g., the mandals of Andhra Pradesh correspond to tehsils of Uttar Pradesh and other Hindi-speaking states and taluka of Gujarat and Maharashtra). The smaller subdivisions (villages and blocks) exist only in rural areas. In urban areas Urban Local Bodies exist instead of these rural subdivisions.
