The Election Commission conducts the SIR process to:

Verify existing voter information
Remove duplicate voter IDs
Update addresses after relocation
Correct spelling mistakes in voter details
Add newly eligible voters
Remove names of deceased or ineligible persons
Improve the accuracy of electoral rolls

A correct voter list helps ensure free, fair, and transparent elections across the country.
