Karnataka SIR 2026: The Ultimate Voter Enumeration & Online Filing Guide

What is the Special Intensive Revision (SIR) 2026?

Karnataka’s Special Intensive Revision (SIR), which officially began on June 30, 2026, is a comprehensive exercise conducted by the Election Commission of India (ECI). Its goal is to clean, purify, and update the electoral roll to ensure that "no eligible citizen is left out and no ineligible citizen is included."

Unlike the annual Special Summary Revision (SSR)—where only those seeking corrections or new enrollments participate—SIR requires every single voter to complete a verification process to eliminate duplicate names, deceased voters, and outdated entries.

The Two Ways to Participate: Offline vs. Online

Voters can complete the revision through one of two methods:

1. Offline (BLO Visit): Your Booth Level Officer (BLO) will visit your house carrying two partially pre-filled copies of your Enumeration Form (EF). You verify/fill in the blanks, sign it, and hand one copy back. Keep the second copy (signed by the BLO) as your receipt.
2. Online (ECI Portal): You can fill and submit the Enumeration Form online by visiting voters.eci.gov.in. This is highly recommended for voters who are currently away from home or did not receive a visit.

Step 3: Map 2002 Historical Records (Self-Mapping & Progeny Mapping)

To combat duplicate entries, the ECI links voters in the current 2025/2026 rolls with historical records from the 2002 SIR.

Structure of the Enumeration Form (EF):

• Section 1: Details of the voter from 2002 SIR (Self-Mapping):
  • If you were registered in 2002, search the database to find your historical Assembly Constituency, Part Number, and Serial Number.
  • If you were not registered in 2002 (e.g., under 18 at that time), skip this section.
• Section 2: Details of Relatives from 2002 SIR (Progeny Mapping):
  • If you filled out Section 1, enter the same relative's details from the 2002 database.
  • If you skipped Section 1, you must enter the 2002 historical records of one of your parents or grandparents (father, mother, grandfather, grandmother). This relative can be from any state in India.
• Section 3: Details of the voter:
  • Fill in mandatory details: DOB, mobile, mother's/father's/spouse's names, Aadhaar number (optional), and parents' or spouse's EPIC numbers.
  • Aadhaar eSign & Consent: During the final submission step, you will be prompted to read the consent and enter your Aadhaar number or VID to generate an OTP on your Aadhaar-registered mobile.

Common FAQs & Troubleshooting

Q1. What if I cannot find my own or any relative's details in the 2002 database?

You will be treated as a "new voter." You should submit the Enumeration Form by filling only Section 1 (your current details). After the draft roll is published on August 5, you must submit a Form 6 along with your age/address proof and declaration during the claims and objections window (Aug 5 – Sept 4).

Q2. Do I need to submit physical documents?

No document submission is required when submitting the Enumeration Form. However, if the Electoral Registration Officer (ERO) has doubts about your eligibility, they may issue a notice requesting verification documents after the draft roll is published.

Q3. What to do if I am not in town?

Any adult family member can fill out the details and sign the Enumeration Form on your behalf. If the entire household is away, complete the form online via voters.eci.gov.in.

Q4. What if my parents have passed away and their names aren't in 2002?

You can search for any maternal or paternal relative (such as an uncle or aunt) who is verified on the 2002 list to establish your progeny mapping.

Q5. What happens if I fail to verify?

Completing the SIR is crucial to keep your name on the electoral rolls. In official statements, authorities have warned that failing to be verified risks deletion of your name from the voter list, which may impact access to citizen benefits.
