Nameplates

Nameplates are small icons (seen in pre-game/post-game lobbies showing player's Gamertags) that can be customized depending on certain requirements. Although nameplate emblems have existed since Halo 2 & Halo 3 in the form of small Seventh Column symbols or the Bungie logo, they have not been customizable until Halo: Reach. Nameplates were first mentioned early 2010, when Halo 2 was being shutdown and again when Halo PC users were told to keep their CD codes.

Players could customize their nameplates by signing up as Bungie.net users until March 31, 2012 when Bungie.net transferred all record-keeping responsibilities to Halo Waypoint and this capability was lost. Halo Waypoint has not yet incorporated nameplates; players are effectively stuck with whichever nameplate they currently have.
