Voter enrolment gaps remaining after the Special Intensive Revision prompted the Election Commission of India to issue instructions covering 20 states and union territories, directing each to run a dedicated outreach effort to bring unregistered residents onto the rolls. The instruction was circulated on 29 September and was raised again during a video call held with Chief Electoral Officers on 1 October.

Younger residents and those reaching voting age for the first time who had not yet registered were included within the scope of the initiative. Voter registration officials — spanning Chief Electoral Officers, District Election Officers, and Electoral Registration Officers in states where the Special Intensive Revision had concluded — were directed to keep enrolment moving through the ongoing continuous updation mechanism.

Participants are to complete the standard Form 6, setting aside the supplementary declaration introduced during the SIR process. Prior to its revision, the digital Form 6 had included a question asking whether the applicant, or any parent or grandparent, appeared on the electoral roll at the time of the most recent SIR. That question had functioned as a mandatory step, with no applicant's submission able to advance until it had been answered.

Broadcast reports indicated that Election Commissioners Sukhbir Singh Sandhu and Vivek Joshi had both raised objections to the alteration, with Sandhu characterising it as a move carried out without authorisation and in violation of applicable rules. A statement from the ECI confined the extra declaration requirement to the SIR phase alone, noting that where the roll revision process had already concluded, electors were to submit the statutory Form 6 laid down by the Registration of Electors Rules, 1960.

Once the Special Intensive Revision process had concluded in a given state, the supplementary declaration field was removed from the ECI's ECINET portal without any public announcement. Direction to cross-reference voter rolls compiled before and after the Special Intensive Revision — flagging any names that no longer appeared — was passed to Chief Electoral Officers. Administrators were directed to locate individuals who may have been missed and support their return to enrolment.

According to participants in the 1 October video conference, Booth Level Officers could be directed to conduct door-to-door checks on voters who lack a mapping elsewhere and have not been flagged as duplicates or deceased. Qualified voters seeking to complete Form 6 are to have support available throughout the process, and state election officials were directed by the ECI to draw on the support of political parties and their booth-level representatives throughout the process.

Questions about how many records were removed during the nationwide SIR have placed this decision under scrutiny. Figures drawn from draft electoral rolls across 30 states and union territories showed approximately 13 crore entries removed, according to media reporting. Objections from Sandhu and Joshi over a range of decisions tied to the SIR — among them proposed alterations to Form 6 and the move to centralise the ECINet electoral roll database — were documented on more than one occasion by the same publication.

At its 26 September gathering, the body clarified that any person whose name was omitted from voter rolls — whether during or following the Special Intensive Revision process, new and first-time registrants included — retained the option to seek enrolment through the ongoing continuous updation mechanism. The announcement added that chief executives would run a dedicated campaign to boost registration numbers.

In a separate move, the Commission outlined steps to address voters who received notices flagging their registrations as either "unmapped" or carrying "logical discrepancies" under the current Special Intensive Revision process. Under this arrangement, Booth Level Officers are tasked with visiting the homes of such voters to gather the necessary paperwork and submit it through ECINET, freeing those individuals from any obligation to attend hearings while the Electoral Registration Officer reviews their cases.
