The list included Ivory Coast defender Kolo Toure, Paraguay's Roque Santa Cruz, Nigeria's Nwankwo Kanu, Argentina's 1978 World Cup winners Osvaldo Ardiles and Ricardo Villa, Italy's Gianfranco Zola and South Africa's Lucas Radebe.
"We feel each and every individual will be a tremendous asset to England 2018," bid chief executive Andy Anson told a Leaders in Football conference at Chelsea's Stamford Bridge stadium.
England players like David Beckham, Wayne Rooney and former greats Gary Lineker and Alan Shearer have already given the bid their backing.
The FA said each ambassador would offer support to England 2018 at home and abroad, including use of their images in promotional materials and in meetings with key figures.
CONCACAF president and FIFA executive member Jack Warner had warned on Wednesday that England's bid needed to exploit its heavyweight support and push players like Beckham to the forefront.
"Some of the guys who have to vote do not know the people on the England bid committee - but they know Beckham, they know Michael Owen," he said.

"I think it was as crude as it was ineffective," he added of that approach. "So we've spent what must seem a long, quiet period listening and learning from the global football family.
"I don't regret that but I take the point that you must move beyond that to put what you have learned to good use, use the great assets effectively and to remember that it is a marathon and not a sprint."
