5.54 crore electors on the roll. 1.08 crore deleted, 43.8 lakh served a notice.
Data as of 10 September 2026. Source: Election Commission of India, SIR 2026.
The Election Commission's Special Intensive Revision put every Karnataka voter through the same test: was the enumeration form filled, and did it match the last roll. 1,07,96,415 electors (19.48% of the roll) were struck off through the ASDDO removal list. A separate 43,80,740 were digitized but flagged for a discrepancy - a SIR notice. This is the seat-by-seat and booth-by-booth picture, with the Commission's own figures set against what we have been able to load.
What the SIR did to Karnataka's roll
The four outcomes of the revision, each shown as the Election Commission's own published figure with a bar tracking how much of it this site has loaded from the removal lists and notice PDFs so far.
From 5.54 crore electors to two separate lists
A voter left the roll one of two ways. If the enumeration form never came back, the entry went on the ASDDO removal list. If the form came back but did not reconcile - name changed, parent's age impossible, no match to the last SIR - the voter stayed on the roll but got a notice.
Who was on the roll, who got deleted, who got a notice
The 2025 Karnataka electoral roll (VoterRecords, 5.52 crore electors), against who ended up on the ASDDO removal list and the SIR notice list.
Search a seat, open it on the map
Type a constituency, pick a metric, and the map re-colours. Select a seat - by clicking it on the map or in the list - and its full breakdown opens beside the map: deletions by reason, notices by category, the Commission's figure against ours, and its 2023 Assembly result.
What the deletions are made of
Permanently shifted, untraceable or absent, death, and already registered elsewhere. Across the state one reason dominates - but the mix is not the same everywhere. Expand a district for its constituencies.

What the notices are checking - and who they land on
"No Mapping" means the digitized form could not be tied to an entry in the last Special Intensive Revision; "Anomaly" means the form reconciled to a person but a field failed a rule. Filter by district or seat below, or click an age band or a rule, and every number on this screen updates. The notice list skews female; the removal list does not.

Deletion and notice rates, against the 2025 roll
Deletions join the 2025 roll at booth level (same AC and part number); SIR notices only join at constituency level, since the notice PDFs use a different part-numbering scheme. Two different resolutions, shown side by side.

One city, a disproportionate share of both lists
"Bangalore" here is BBMP's three zones (Central, North, South) plus the Bangalore Urban seats outside BBMP. Bangalore Rural is a separate district, geographically outside the city, and is counted with the rest of Karnataka below.

SIR notices by constituency: official figure vs what we loaded

Districts, constituencies and booths against the 2025 roll
Electors as recorded on the 2025 Karnataka roll (VoterRecords, 5.52 crore electors) - a different base than the Commission's SIR figure used elsewhere on this page, close but not identical. Deletion and notice rates here are computed against this base. Click a district for its constituencies, then a constituency for its booths.
