MEC's sponsorship business landed the brief after a pitch held through the consultant Creativebrief.
The WPP-owned MEC Access will assess the sponsorship market for Vodafone to identify potential opportunities in areas that could include sport, music, entertainment, arts and culture.
WPP handles advertising for Vodafone through its Team Red division, but the search is understood to have extended beyond WPP shops.
Although the initial appointment is to work with Vodafone on reviewing opportunities, MEC Access could then work with the brand on signing the deal and activating the partnership.
It is thought that Vodafone hopes to find a sponsorship as significant as its support for the McLaren Formula One team, which runs until at least the end of 2013.
