Special Intensive Revision (SIR)
Process and Purpose
SIR is the most comprehensive form of electoral roll revision conducted by the ECI. Unlike ordinary (summary) revision, which updates rolls based on applications received, SIR involves door-to-door verification by BLOs covering every registered voter. The process involves: (1) generating draft rolls, (2) house-to-house enumeration by BLOs to verify existing entries and identify omissions, (3) filing of claims and objections by citizens, (4) adjudication by EROs, and (5) publication of final rolls. SIR is typically conducted before major elections (Lok Sabha, assembly elections in large states) to ensure roll accuracy. The 2025–26 national SIR is notable for its phased all-India scope — encompassing the entire electorate of nearly 97 crore registered voters.
- BLO (Booth Level Officer) — grassroots officer responsible for 1 polling station (~1,200 voters); verifies rolls door-to-door
- ERO (Electoral Registration Officer) — typically sub-district level; adjudicates claims and objections
- Draft roll publication → Claims/objections period → Final roll — the standard SIR timeline
- Voter ID card (EPIC — Electoral Photo Identity Card) — primary voter identity document; issued free
- Aadhaar linking with voter roll: EC has been linking Aadhaar with EPIC to eliminate duplicates, under Section 23(4) of RPA 1950 (voluntary, not mandatory by court order)
- Grounds for deletion: death, shifting of residence, double entry, foreign illegal immigrant
