The EPIC number, or Electors’ Photo Identity Card number, is a unique 10-character alphanumeric code issued by the Election Commission of India (ECI) to every registered voter.
It comprises 3 letters (representing the state or constituency code) followed by 7 digits (the voter’s unique identification number).
Example: ABC1234567
It ensures authentic identification, prevents duplication, and is also available digitally through the e-EPIC facility on the National Voters’ Services Portal (NVSP).
