A different revision
Assam was left out of the Special Intensive Revision. On 17 November 2025 the Election Commission ordered a Special Revision of Assam's roll instead, under section 21 of the Representation of the People Act. The table sets each rule of the Assam order beside the rule the SIR states followed, with the paragraph of the Assam order it comes from.
The roll, step by step
The roll of January 2025 is the last one before the revision. Booth officers then went from house to house between 22 November and 20 December 2025 with a printed list of the electors already on the roll. The draft came out on 27 December, claims and objections ran to 22 January, and the final roll came out on 10 February 2026. The bars start above zero so that the changes can be seen.
Constituency by constituency
The Chief Electoral Officer published the final roll of 8 February 2024, the draft and the final roll for each of the 126 constituencies, by sex. Each constituency's change from the draft to the final roll is the names added less the names removed. The tables do not give the two apart, so a constituency whose roll fell may still have added names, and the change says nothing about why.
Every constituency
Names flagged for deletion
With the draft, the Chief Electoral Officer gave a count of names marked for deletion under three reasons. A reason is what the officer wrote down, and nobody checked it.
D-voters
A D-voter, for doubtful voter, is an elector whose citizenship has been questioned and sent to a Foreigners Tribunal to decide. The category exists only in Assam. The order for the revision kept D-voters out of the house-to-house check and carried every one of them onto the draft unchanged, to be changed or removed only on the order of a tribunal or a court.
Foreigners Tribunals
Foreigners Tribunals are quasi-judicial bodies that decide whether a person referred to them is a foreigner. Cases come from two places, the D-voter list and the Border Police. These are the figures the Ministry of Home Affairs gave the Lok Sabha up to 2021, and the figures the Chief Minister gave the Assam Assembly in July 2026, which reached us through the press.

Detention centres
People declared foreigners by a tribunal, and foreigners convicted of an offence, are held in detention centres. The latest figures for each centre that we could find in a primary source are the Ministry of Home Affairs' answers to the Lok Sabha of December 2019 and March 2020.
The 2019 NRC
Two lists of Assam's National Register of Citizens, the supplementary list of inclusions and the list of exclusions, were published on 31 August 2019 under the Supreme Court's supervision. The Ministry of Home Affairs told the Lok Sabha in 2021 that the final register had not been issued. The register is kept apart from the electoral roll, and the order for the 2025-26 revision does not mention it. The NRC page sets out the law behind it, the record since 2019 and how the SIR differs.
