It means you will be forever remember with the team who retired your number. No one else on that team can have your number. Actually, if the organization sees fit anyone can wear the number even while it's retired. It'll still be retired and people will remember who wore it, but the number will be considered active.

Number 12 represents the Seahawks fans. At every home game the 12th man flag is raised by a former player or some sort of celebrity. Seahawks stadium is very loud and the crowd noise has been known to affect visiting teams because they aren't used to that much noise. So the fans are considered to be part of the team....to an extent.
Bruce Smith's jersey number (54) was the first to be retired by the Minnesota Golden Gophers football team, in 1977.
Answer The Seattle Seahawks have retired four numbers in their history. The first number they have retired is the number 12 in 1984, which represents the "12th Man", the amazing fans of the Seattle Seahawks who year in and year out cause the most false start penalties in the NFL at Qwest Field and in the Kingdome, and for their short two year time in Huskies Stadium. The number 12 was retired to honor the fans, and the flag representing the 12th Man is raised before every home game by an honorary guest, including Ichiro Suzuki, Mack Strong, and Paul Allen just to name a few. Number 80 for wide receiver Steve Largent was retired in 1996. When Jerry Rice joined the team in the 2004 season, Largent's number 80 was unretired with Largent's permission. When Rice left the team during the offseason for the Denver Broncos, the number 80 was re-retired. Offensive Tackle Walter Jones' number 71 was retired in 2010. And finally, number 96 was retired for Defensive Tackle Cortez Kennedy in 2012.
