Revenue Divisions are the administrative divisions in districts of some of the Indian states. These divisions are sub-divided into mandals. The mandals are in turn divided into villages and hamlets. There are 50 revenue divisions in Andhra Pradesh, of which East Godavari district has as many as 7 divisions and Vizianagaram district has the least number with 2 divisions. Revenue Divisional Officer (RDO) is the head of the division.
