What is Special Intensive Revision (SIR)?

The Special Intensive Revision (SIR) is a voter verification exercise by the Election Commission of India. It will ensure that only eligible Indian citizens aged 18 or above remain on the electoral rolls. It involves door-to-door verification by Booth Level Officers (BLOs) using Unique Enumeration Forms (EFs).

If an elector’s name appeared in the 2002–2004 SIR rolls, no additional documents are required. However, voters added after that must provide eligibility documents to confirm their citizenship and residence.

Why is SIR Needed?

The need for SIR arises due to increasing migration and outdated voter lists. Electoral rolls must be revised before every election or when required as per law. The last SIR took place over 21 years ago (2002–2004).

Also Political parties have raised concerns about incorrect and duplicate entries, deceased voters, and wrongful inclusion of non-citizens. Frequent migration, unremoved dead voters, and duplicate registrations have made revision essential to maintain the purity of electoral rolls and strengthen democracy.

The SIR is a large administrative exercise involving several key officials:

  • Booth Level Officer (BLO): One per polling station (around 1,000 electors each)

  • Assistant ERO (AERO): Assists EROs at the tehsil level.

  • Chief Electoral Officer (CEO): Hears second appeals at the state level.
