The door-to-door enumeration phase of Special Intensive Revision (SIR) of electoral rolls in Karnataka commenced on June 30, 2026.

Presented by the Election Commission of India (ECI) as an exercise to prepare a ‘pure’, ‘accurate’, and ‘inclusive’ electoral roll, SIR has become one of the most debated electoral exercises in recent years.

Electoral rolls are ordinarily updated through the routine Summary Revision process, where voters apply to enrol, correct details, change their address, or remove the names of deceased family members.

Along with the annual Summary Revision, the Election Commission has conducted Intensive Revisions, during which BLOs visit voters, verify the details furnished by them, and correct the electoral rolls. These exercises were generally conducted once every five or 10 years.

However, the SIR is different. Instead of relying primarily on applications from voters, now, Booth Level Officers (BLOs) will conduct door-to-door verification, distribute enumeration forms, collect them back, and verify the information before preparing a fresh draft electoral roll.

Here is everything you will need to know to navigate the enumeration process.

Electors can obtain assistance regarding the Special Intensive Revision at Voter Facilitation Centres (VFCs) and Booth Level Officer (BLO) facilitation centres functioning across Karnataka.

Services for voters include assistance in filling enumeration forms, details of the BLOs for each polling area, contact information of Electoral Registration Officers and other election officials, guidance on enrolment and correction of electoral roll entries.

Similarly, BLOs can use the BLO facilitation centres if there are network and other issues. Information is available at: https://ceo.karnataka.gov.in/vfc/details/
