The Indian voter ID card is an identity document issued by the Election Commission of India to adult domiciles of India who have reached the age of 18, which primarily serves as an identity proof for Indian citizens while casting their ballot in the country’s municipal, state, and national elections. It also serves as general identity, address, and age proof for other purposes such as buying a mobile phone SIM card or applying for a passport. It is also known as Electoral Photo ID Card (EPIC).
