Everything you need to know about SIR 2.0
What's the story
The Election Commission of India (ECI) has launched the second phase of its Special Intensive Revision (SIR) exercise in nine states and three Union Territories from Tuesday, November 4, 2025. The initiative aims to update and maintain accurate electoral rolls across these regions, which together have a voter base of over 51 crore. The final electoral rolls will be published on February 7, 2026.
Participating regions
List of states, union territories involved
The states and Union Territories involved in this round of SIR are Andaman and Nicobar Islands, Lakshadweep, Chhattisgarh, Goa, Gujarat, Kerala, Madhya Pradesh, Puducherry, Rajasthan, Tamil Nadu, Uttar Pradesh, and West Bengal. The first phase was conducted in Bihar, where a final voter list with nearly 7.42 crore names was published on September 30 ahead of its Assembly elections starting November 6.
Revision rationale
Assam will have separate revision orders
The SIR exercise is aimed at adding eligible voters and removing those who are no longer eligible, such as deceased persons or those registered in multiple locations. However, Assam will have separate revision orders as a Supreme Court-supervised exercise to verify citizenship is underway. "Under the Citizenship Act, there are separate provisions for citizenship in Assam. Under the supervision of the Supreme Court, the exercise of checking citizenship is about to be completed," Chief Election Commissioner Gyanesh Kumar said.
Cleanup schedule
SIR process to begin today
The SIR process will continue till December 4. Draft electoral rolls will be released on December 9, with final lists published on February 7. This is the ninth such exercise since independence and aims to ensure that no eligible elector is left out while ineligible ones are removed from the electoral rolls. Citizens can make claims and objections between December 9 and January 8, and hearings and verifications must be completed by January 31, 2026.
Reactions and requirements
Political parties in Tamil Nadu to challenge SIR exercise
Unlike previous rules, electors need not submit documents at the enumeration stage but will do so when served notice by electoral registration officers if they cannot be linked with past SIRs. Ahead of the SIR 2.0 rollout, the Tamil Nadu government challenged the SIR in the Supreme Court, with CM MK Stalin accusing the ECI of attempting to remove "true voters." Of the 12 states and UTs, Tamil Nadu, Puducherry, Kerala and West Bengal are due for polls in 2026.
