AICC is responsible for decision-making and policy formulation for the party at the national level.

The original headquarters of AICC were located at Swaraj Bhavan,[note 1] Allahabad, however after independence of India in 1947, it was shifted to 7, Jantar Mantar Marg, near Jantar Mantar, Delhi and subsequently to 24 Akbar Road, right behind 10 Janpath, after the 1969 Congress split, under Indira Gandhi.

[2] Today, its institutional records are part of the Archives at the Nehru Memorial Museum & Library, at Teen Murti House, Delhi.

The AICC on the other hand is composed of delegates sent by the various State–level Pradesh Congress Committees, who themselves have been elected or nominated to their respective Pradesh Congress Committee from the district and panchayat level party units.

Besides the President, these delegates also elect the Congress Working Committee,[4] which is the apex decision-making body of the organisation.
