Kelkar added that the untraced category included voters to whom BLOs could not hand over enumeration forms.
He said details of the untraced voters would be published on the official website, allowing people to verify their names.
The information would also be shared with political parties, he added.
However, representatives of various political parties raised concerns over alleged discrepancies in the Election Commission’s figures on untraced voters.
Kelkar said the SIR process had been completed in Kasaragod, Kollam, and Wayanad districts and would be completed in the remaining districts soon.
The SIR, which began here last month, was extended following the local body elections.
