They have each been awarded six Pencils. Grey London was awarded two Pencils for its "life paint" campaign for Volvo, which won two Grands Prix at Cannes last year.
Ogilvy & Mather London, Ogilvy & Mather Johannesburg, Ogilvy & Mather Singapore and The Community are joint third with five Pencils each.
The UK is leading the pack with 53 Pencils and the US is in second place with 40.
There were 157 Pencils awarded today, on the second day of judging. The advertising category picked up 20 Pencils.
The winners will have to wait until the D&AD Awards on 19 May to find out whether they have won a wood, graphite, yellow, white or black Pencil.
Further Pencils will be awarded until the judging ends tomorrow.
Tim Lindsay, the chief executive at D&AD, said: "There’s been another strong showing for the white Pencil category this year with 36 winners, proving that creativity for good is alive and well.
"These results are a timely reminder of why brands and agencies must work together to make a change for the better.
"With the launch of D&AD Impact we envision this category growing and becoming even more integral to the creative industry."
