The Election Commission of India (ECI) has made it mandatory for citizens to link their Aadhaar card with Voter ID (EPIC number) to prevent duplicate entries and ensure transparent elections. This process, known as EPIC–Aadhaar Seeding, can be done online, via mobile app, SMS, or even offline through your local BLO (Booth Level Officer).
In this guide, we explain the required documents, step-by-step methods, tracking process, and why linking Aadhaar with Voter ID is important in 2025.
