The reminder will be rolled out in 13 Indian languages - English, Hindi, Gujarati, Tamil, Telugu, Malayalam, Kannada, Punjabi, Bengali, Urdu, Assamese, Marathi and Oriya.
"As part of our efforts, on National Voters Day on January 25, a voter registration reminder will appear at the top of the News Feed as a reminder service for all the voters," said Shivnath Thukral, Public Policy Director for India & South Asia.
By clicking on the 'Register Now' button, people will be directed to the National Voters' Services Portal which will guide them through the registration process.
Facebook had rolled out similar reminder in partnership with Election Commission of India in 2017.
Facebook has over 200 million users in India.
