The Grecians striker tragically lost his battle with bowel cancer earlier this month.
"Adam wore the number nine shirt with pride and distinction while making it his own during every one of his 158 appearances for the Grecians," a club spokesman told the Bridgewater Mercury.
"And supporters, family and playing staff alike agreed with this wish to retire the number nine."
Mourners paid their respects to Stansfield at his funeral on Tuesday. Two funds have been set up in his memory - the Adam Stansfield Family Fund to support his wife Marie and three young children and the Adam Stansfield Football fund which will provide money for youth football programmes in south west England.
