The BMW-owned luxury car manufacturer has approached a number of shops through the AAR. A shortlist is expected next month, with a final result scheduled for August.
It is understood that the car-maker is looking for agencies with experience beyond advertising, including customer relationship marketing, trade events and direct marketing.
The search comes just four months after Graham Lenden was appointed as the head of marketing, replacing Paul Ferraiolo, who was promoted to president of North America. Lenden was previously the head of operations at Aston Martin.
Rolls-Royce's last major ad campaign was created by WCRS in 2007.
The company is currently planning a series of versions of the "Baby Rolls" that are likely to be unveiled next year.
