India, often regarded as the world’s largest democracy, is famous for its diverse culture, vibrant political system, and constitutional values that uphold freedom, equality, and justice. Recently, general elections were held in Assam, Kerala, Puducherry, Tamil Nadu, and West Bengal. Amid the election season, the word ‘ Special Intensive Revision (SIR)’ trended across social media platforms and news headlines. Several questions lingered in a common man’s mind regarding the Special Intensive Revision. In this article, we have provided you with the necessary details related to Special Intensive Revision.

What do you mean by Special Intensive Revision?

SIR is a participative exercise involving all stakeholders including electors, political parties and election officials. ECI requests all political parties to appoint BLAs for each Polling Booth, in order to ensure full participation of political parties so that SIR is conducted with complete transparency and full participation of political parties.

On May 14, 2026, the Election Commission of India(ECI), in exercise of its powers under Article 324 of the Constitution of India, Section 21 along with other applicable provisions of the Representation of the People Act, 1950, has ordered Special Intensive Revision (SIR) in 16 States and 3 Union Territories (UTs).

“No eligible citizen is left out while no ineligible person is included in the Electoral Roll,” is the key objective of the Special Intensive Revision. Every person who is a citizen of India and who is not less than eighteen years of age on the qualifying date and is not otherwise disqualified under any law shall be entitled to be registered in the electoral roll.

According to the press release published on May 15, during SIR, BLOs will conduct house-to-house enumeration. Every existing elector, whose name exists in the electoral roll, will be made available an Enumeration Form (in duplicate) through BLOs. The elector has to fill the enumeration form, filling his/her required details and has to return one copy to the BLO. Provision will also be given to electors to fill Enumeration Form online during the SIR period.

Enumeration Phase has started for the states of Odisha, Mizoram, Sikkim, and Manipur on 30.05.2026. All eligible electors whose Enumeration Forms are received by the Electoral Registration Officer (ERO) on or before June 28, 2026, will be included in the Draft Electoral Rolls. Electors who are unable to submit their Enumeration Forms by June 28, 2026, may apply through Form 6 along with the prescribed Declaration Form during the claims and objections period.
