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.How to fill the enumeration formThe enumeration form will be partially pre-filled with details already available in the electoral roll.Voters must first verify whether these pre-printed particulars such as their name, EPIC number, age, gender and address are correct. They then need to fill in the remaining fields, including their mobile number, place and date, and sign or affix a thumb impression.The main part of the form is providing the details of the electoral roll in which the voter or an immediate family member (such as a parent) appeared during Karnataka’s last SIR in 2002.The Election Commission has said electors can check these details through the Voters’ Service Portal if they do not remember them.The Election Commission has said electors can check these details through the Voters’ Service Portal if they do not remember them.Timeline of the SIR exercise
