White retired as a player in 1990 after 18 major-league seasons. On May 2, 1995, the Royals retired White's number 20, and the same year he was inducted into the Royals' Hall of Fame. A bronze statue of White was dedicated outside of Kauffman Stadium in 2004, joining Royals founders Ewing & Muriel Kauffman, George Brett, and as of 2009, Dick Howser.
After the end of White's playing career, he coached with the Royals and then the Boston Red Sox. He then managed the Wichita Wranglers for three years before moving in Kansas City's front office. Frank White was said to be one of Dayton Moore's favorites to fill the Kansas City Royals vacant manager position starting in 2008 that ultimately went to Trey Hillman.
In February 2008 it was announced that White was joining FSN Kansas City to serve as a part-time color commentator on Royals telecasts (filling in for Paul Splittorff on select games), as well as an analyst on the channel's Royals Live postgame show.
White resigned his position in the front office in January 2011.  Fox Sports Kansas City announced in early December 2011 that White's broadcasting contract wouldn’t be renewed as the Royals' television color commentator.
