Prospective fundraisers will be prompted by promotional material over the course of the campaign to text "famine" to 81222, in order to receive a fundraising pack.
The campaign launches on October 1 and culminates with the 24-hour famine during March 14-16 2008.
Broadsystem will collect and validate consumer data through a series of fully automated text interactions to enable accurate and cost-effective fundraising pack despatch.
The work was awarded to Broadsystem without a competitive pitch.
Matt Wenham, youth marketing manager at World Vision, said: "We are confident that SMS will drive registration rates, participation in the famine and ultimately fundraising to new levels."
Caroline Worboys, CEO at Broadsystem, said: "The use of SMS activity will make it easy for the audience to get involved in the campaign and provide a cost efficient means for World Vision to establish dialogue with its key audience for this campaign."
Broadsystem, a wholly owned subsidiary of News International, is headquartered at Gerrards Cross and has offices in Bristol.
