The Special Intensive Revision (SIR) is a house-to-house re-verification of the electoral roll by the Election Commission of India (ECI) to make the voter list accurate — adding eligible citizens who are missing and removing entries that are deceased, shifted, duplicated or otherwise ineligible. If your state is in the current round, a Booth Level Officer (BLO) visits your home with a pre-filled Enumeration Form, or you can fill it yourself online at voters.eci.gov.in. This guide explains, in plain language, what SIR is, why it is happening now, exactly how to fill the form, which documents are accepted, and the state-wise deadlines.

Why is SIR happening now?
The last intensive, document-based revision in many states was decades ago, and rolls accumulate errors over time — voters pass away, families move, and duplicate entries creep in. The ECI is carrying out SIR in phases so that every constituency has a clean, up-to-date roll before upcoming elections. Phase 1 was Bihar (2025); Phase 2 covered 12 states and UTs (including Tamil Nadu, Uttar Pradesh, Rajasthan and Madhya Pradesh) with final rolls published on 7 February 2026; Phase 3 (announced May 2026) covers 16 states and 3 UTs, including Karnataka, Telangana, Maharashtra, Jharkhand, Haryana, Odisha, Punjab and Delhi.
How to fill the SIR Enumeration Form
You have two easy options:
- Through your BLO: The BLO delivers a pre-filled form to your house. Check every detail, sign both copies, attach a document if asked, and hand one copy back. Keep the counterfoil/acknowledgement.
- Online yourself: Open voters.eci.gov.in, choose Fill Enumeration Form under SIR-2026, log in with your mobile number and captcha, select your state, enter your EPIC (Voter ID) number, verify the pre-filled details, complete the mobile OTP and submit. Your mobile must be linked to your EPIC.
Which category do I choose?
The form asks you to pick one: (a) my name is in the last SIR/intensive roll; (b) my parents’ name is in that roll; or (c) neither. For (a) and (b) the process is simplest. For (c), you attach one document from the ECI list that establishes your date and/or place of birth.
Documents accepted in SIR
The ECI has a prescribed list (any one is enough to establish date/place of birth), including: birth certificate; passport; matriculation/other educational certificate; a government or PSU employee/pensioner ID or Pension Payment Order; any government/local-body/bank/post-office/LIC document issued before 1 July 1987; permanent residence certificate; SC/ST/OBC caste certificate; family register; and government land/house allotment papers. Aadhaar is optional — it is accepted as proof of identity, but on its own it is not treated as proof of citizenship or date of birth, so keep one of the above ready if you can.
State deadlines (Phase 3)
Dates have been revised, so always confirm on your state CEO website. As of mid-July 2026: Telangana enumeration up to 3 August (draft roll 10 August, final 12 October); Karnataka enumeration up to 8 August (draft roll 17 August, final 19 October); Maharashtra final roll around October. Phase 2 states such as Tamil Nadu and UP already have their final rolls (7 February 2026) and now follow normal continuous updation.
How to check your name in the roll
Go to electoralsearch.eci.gov.in and search by EPIC number or by name/details. When the draft roll is published, check again — if your name is missing you can file a claim, and wrong entries can be challenged through an objection during the claims-and-objections window.
Frequently asked questions
Is Aadhaar compulsory for SIR?
No. Giving your Aadhaar number is optional, and Aadhaar alone is not treated as proof of citizenship.
Will I lose my vote if I miss the form?
Don’t panic — submit as early as you can and, if the draft roll misses you, file a claim in the objection window. Contact your BLO or call 1950.
Is SIR legal?
Yes. In May 2026 the Supreme Court upheld the ECI’s power to conduct SIR under the Representation of the People Act.
Information last verified: 17 July 2026. SIR dates and document rules are being revised state by state — always confirm on the official ECI/CEO portal before acting.
