EC announces Special Summary Revision of voters’ list in 17 states amid SIR row

While a Summary Revision focuses on new eligibles and routine corrections, SIR goes far deeper, involving statewide house-to-house verification, detailed scrutiny of entries, and large-scale data audits. For instance, under a Summary Revision, a voter who has shifted homes must file a form to update their address. Under SIR, the Booth Level Officer visits that address, confirms whether the voter still lives there, checks if anyone new has become eligible, and updates the roll based on physical verification rather than waiting for the voter to initiate the change.
