FVR stands for Field Verification Report in the context of Voter ID application. After submitting the Voter ID application form along with the required documents, a Booth Level Officer (BLO) is assigned to verify the details provided in the application form. The BLO visits the applicants residence to verify the information provided in the application form, such as the applicants name, age, address, and photograph. The BLO then prepares a Field Verification Report (FVR) based on the verification process, which is submitted to the Election Commission of India. The FVR is an important step in the successful submission of the Voter ID application, and the application is accepted or rejected based on the merits of the case.
