The Election Commission of India has launched Phase 2 of the Special Intensive Revision (S.I.R) — a massive voter roll update across 12 states and Union Territories, including Tamil Nadu, Kerala, Uttar Pradesh, Gujarat, and West Bengal. Starting October 28, this ground-level verification aims to clean electoral rolls by identifying duplicate, deceased, and ineligible voters. Unlike routine annual updates, S.I.R is an extensive process involving door-to-door verification by Booth Level Officers.
