The turnaround in India's One-day fortunes saw it gain three spots on the ODI championship table.
The 2-2 result in the five-match series against the Proteas brought a gain of two points to Rahul Dravid's side, lifting their rating to 109.
Although the tally is the same as that of Sri Lanka and England, India moved above both of them (and New Zealand) when ratings were recalculated to three decimal points.
Teams in the top six positions on Aril 1, 2006 would automatically qualify for the second stage of the ICC Champions Trophy, to be held in India next year. The four teams below sixth spot would have to qualify through preliminary round competitions.
However India, being the hosts, would automatically be in the second stage regardless of their position on the table.
South Africa hold on to second spot, 18 points behind World Champions Australia. Pakistan is ranked third.
In the individual rankings, Rahul Dravid is the only Indian batsman in the top 10 at number seven, a drop of one spot. Irfan Pathan is ranked eighth among ODI bowlers, a gain of two places.
The top three spots among batsman continued to be occupied by Adam Gilchrist, Ricky Ponting and Graeme Smith respectively.
Glenn McGrath leads the bowling ratings ahead of compatriot Brett Lee. South African Shaun Pollock gains two spots to come third.
