Karnataka is launching a month-long door-to-door voter enumeration drive starting Tuesday, aiming to update rolls for 5.5 crore citizens. (Representative image)BENGALURU: The Election Commission of India (ECI) is set to launch door-to-door enumeration visits in Karnataka from Tuesday, marking the beginning of its Special Intensive Revision in a monthlong exercise scheduled to conclude on July 29.The drive seeks to cover 5.5 crore electors in the state.Chief electoral officer Anbu Kumar Monday said enumeration forms will be given to all electors, whose names were on the rolls as of June 16 this year. The biggest challenge, however, is distribution of forms, their collection and digitization, he added.Of the 68,000 officials working on SIR in the state, a total of 59,050 are booth-level officers (BLOs) deployed to cover 1.8 crore households in the state. Given the history of contentious SIR drives in other states, both Congress and BJP have cranked up their vigilance machinery in Karnataka, deploying personnel at booth level to ensure eligible voters retain their right and also help new or left-out voters join the rolls of eligible voters.Congress has created two war rooms involving 370 people. BJP has established a multi-tier monitoring system with five-member teams at the constituency level.Notice doesn't mean deletion: ECSIR will ring your doorbellNearly 9,000 BLOs will fan out across the city from Tuesday as SIR of electoral rolls enters its field-verification phase.The enumeration drive will continue till July 29, during which BLOs will visit every household to distribute enumeration forms and assist voters in filling them. Residents must complete, sign and return the forms to BLOs, who have been instructed to make at least three visits to collect the forms if voters are unavailable during the initial visit.Ahead of the exercise, Greater Bengaluru Authority (GBA) officials completed pre-SIR mapping of electoral records. Of the city’s over 1 crore voters across 28 assembly constituencies, 76.3% have been mapped by matching entries in the 2025 electoral roll with the 2002 one. Around 24.6 lakh voters remain to be mapped during the ongoing exercise.All you should know and do to cast your voteGBA chief commissioner Maheshwar Rao urged voters not to panic if their names haven’t been mapped or even if they cannot be traced back to the 2002 voter list. “In case this happens, voters can submit details with relevant documents to the BLO to ensure their names are retained in the draft,” he said.Voters can also download the enumeration form, fill it online and upload the supporting documents. However, BLOs will still conduct a physical visit to verify the submitted information.BLOs cannot make changes sans requestBLOs, the ground force in voter-revision exercise, will visit houses and paste colour-coded stickers: Purple means enumeration forms are distributed; red means houses were found locked or door shut.For those not at home, stickers will specify tentative dates of the next two visits and slip the enumeration form under the door.“Each BLO will visit an average of 900 houses,” said Anbu Kumar. BLOs are the custodian of rolls, but they cannot make changes without the voter seeking it.Kumar said BLOs are supposed to digitise filled-in forms. If they do not get internet on the go, BLO facilitation centres with Wi-Fi are set up in each taluk to tide over technical issues.
