Mr Shah met former Army Chief General Dalbir Singh Suhag at his residence in Delhi's Mandir Marg and kicked off the programme. He handed Mr Suhag a few booklets on the achievements of the Modi government.
The BJP chief tweeted: "Launched the nationwide campaign 'Sampark for Samarthan', a door-to-door initiative aimed at making people aware of the transformative initiatives undertaken by Prime Minister Narendra Modiji's government in the last four year."
He was earlier scheduled to launch the contact programme from Mr Suhag's residence in Haryana's Gurugram, but that was cancelled at the last minute, a party official said.
Mr Shah would personally meet at least 50 eminent personalities to enlighten them about the BJP-led National Democratic Alliance government's achievements.
It is part of the party's effort to reach out to maximum number of people ahead of the 2019 Lok Sabha polls.
About 4,000 senior party workers, including Union Ministers, Chief Ministers and Deputy Chief Ministers of states, would carry out the campaign to meet more than one lakh well-known personalities to discuss the Modi government's achievements.
Besides, parliamentarians, legislators, District Panchayat members and senior office bearers will also pitch in.
PM Modi, also as part of the campaign, addressed beneficiaries of the Ujjwala Yojana and Mudra Yojana on Monday and Tuesday respectively, through the NaMo app.
