NEW DELHI: Enumeration for Phase 3 of special intensive revision (SIR) – which shall cover over 37.7 crore electors across 16 states and UTs in all under different schedules – has started in Odisha, Mizoram, Sikkim and Manipur. The exercise will verify the eligibility of around 3.7 crore electors across the four states, based on three key criteria as per Article 326 of the Constitution: being a citizen of India, not less than 18 years of age, and not disqualified under any law.As of May 14, 2026, the number of electors stood at 3.3 crore in Odisha, 20.9 lakh in Manipur, 8.7 lakh in Mizoram and 4.7 lakh in Sikkim. Manipur is due for assembly polls early next year, along with Goa, UP, Uttarakhand and Punjab.The enumeration phase in Odisha, Mizoram, Sikkim and Manipur, which started on Saturday, will continue till June 28. As per the order issued by EC on May 14, eligible electors whose enumeration forms are received by electoral registration officers by June 28 will be included in the draft poll rolls to be published on July 5. This will be followed by a month-long window for filing claims and objections, which shall end on Aug 4. The claims and objections are to be settled by Sept 2 at the latest, followed by publication of the final poll rolls for four states on Sept 6.“All eligible electors are requested to participate in the SIR process and cooperate with poll officials during the house-to-house visits,” EC said on Sunday.Phase 3 of SIR comes in the wake of SC’s ruling upholding SIR exercise and all related procedures and processes. SC, in the order issued last week, validated EC’s mandate to examine the citizenship of a person for the limited purpose of inclusion in the poll rolls.
