What is SIR? Special Intensive Revision
A plain-language guide to India's electoral roll revision process — what it is, its history, and how it affects every citizen's right to vote.
A special drive to update, correct and clean up the voter list — adding eligible new voters, removing deceased or shifted entries, and fixing errors.
📅
When does it happen?
The ECI announces SIR periodically — usually before major elections. A draft list is published, then claims and objections are invited from the public.
👤
Who conducts it?
The Election Commission of India (ECI) conducts SIR through local Electoral Registration Officers (EROs) and Booth Level Officers (BLOs) at the ground level.
🗳️
Why does it matter?
If your name is missing, wrong, or at the wrong polling booth — you cannot vote. SIR is your opportunity to fix that before the rolls are finalised.
Brief History of Electoral Roll Revision in India
1950
The Representation of the People Act, 1950 established the legal foundation for preparing and maintaining electoral rolls in India.
1950s – 1970s
Electoral rolls were prepared manually, house-to-house. Errors and omissions were common due to the scale and manual nature of the work.
1980s – 1990s
The ECI introduced structured revision cycles. Photo voter ID cards were introduced in 1993, replacing name-only entries.
2000s
Computerisation of electoral rolls began. The EPIC card became the standard. Online registration portals gradually replaced physical visits.
2015 onwards
NERPAP launched — linking EPIC with Aadhaar to eliminate duplicate entries. voters.eci.gov.in enabled fully digital registration and corrections.
2022 – Present
The ECI introduced quarterly roll updates (January, April, July, October) — giving citizens more windows to enrol or correct details throughout the year.

About the BLO Form
The BLO brings 2 identical printed forms to your home. Your existing voter details are already pre-printed on the form by the BLO. You only need to fill in the remaining blank fields — in Kannada or English, whichever you are comfortable with. Sign with date before handing it back.
1
Self Mapping
Your own details are present in the 2002 Electoral Roll
The form has two columns at the top and a section below. In this case: ① Fill the left column only — enter your own details from the 2002 roll (your name, EPIC number, etc.) in that left column. ② Fill the section below — complete all the remaining fields at the bottom of the form (date of birth, mobile number, Aadhaar, etc.).
Leave the right column blank. Sign with date at the bottom.
2
Progeny Mapping
You did not vote in 2002 or your details are not found — but a parent or grandparent's details are available
In this case: ① Fill the right column — enter the details of the family member whose name appears in the 2002 roll (father, mother, grandfather or grandmother — whichever is available). ② Fill the section below — complete all the remaining fields at the bottom of the form (your own date of birth, mobile, Aadhaar, etc.).
Leave the left column blank. Sign with date at the bottom.
Which family member to use? Use whichever appears in the 2002 roll — father first, then mother, then grandfather, then grandmother. Only one is needed.
3
No 2002 Record Available
Neither your details nor any family member's details are found in the 2002 Electoral Roll
In this case: ① Leave both the left and right columns completely blank. ② Fill only the section below — complete all the fields at the bottom of the form (your date of birth, mobile, Aadhaar, etc.). ③ Attach a birth proof document along with the form.

Frequently Asked Questions
Search your name on electoralsearch.eci.gov.in or use the Electoral Roll Search tab in this tool to look through the PDF you have. You can also ask your local BLO who visits your area during SIR drives.
File Form 6 on voters.eci.gov.in to re-enrol. If you believe it was removed in error, you can also file an objection during the claims period of a SIR drive. Contact your local ERO office with your Aadhaar and proof of residence.
Summary Revision is a desk-based update using existing records — BLOs do not visit every home. It is faster and used for routine quarterly updates.
Special Intensive Revision (SIR) involves door-to-door visits by BLOs to physically verify voters at every household. It is more thorough and ordered by the ECI before major election cycles.
Not automatically. You need to:
File Form 8A (if staying in the same constituency) to update your address
Or file Form 6 at your new constituency and Form 7 to delete your entry from the old roll
The ECI has four qualification dates each year — 1 January, 1 April, 1 July and 1 October. You can apply anytime, but applications submitted before each date are processed for that quarter's roll update. Aim to apply at least 3 months before any election.
Both channels work. Online through voters.eci.gov.in is the fastest way. However, during a SIR drive your BLO will visit your home — a good opportunity to verify details, hand in forms, and ensure your entire household is enrolled.
How SIR Directly Affects You
✅
Your vote is protected
A clean, accurate roll means your vote can only be cast by you. SIR removes ghost entries and duplicates that could dilute the integrity of elections.
📍
Your polling booth may change
During SIR, booth boundaries are sometimes reorganised. Always verify your assigned polling booth before election day.
⚠️
Missing names happen — act early
Names can be mistakenly deleted if BLOs cannot verify a resident (locked house, no response). If you moved temporarily during a SIR visit, check your name online and re-enrol if needed.
