Multiple outlets report that Phoenix Suns star Devin Booker plans to change his jersey number ahead of the 2026-27 NBA season. Both reports note that Booker has worn the No. 1 jersey since entering the league after being selected in the 2015 NBA Draft. The articles frame the move as a change to his longstanding uniform number, but they do not specify which jersey number Booker would switch to, nor do they provide details on the reason for the change. The reports also do not indicate whether the Suns have made any official announcement. Based on the information provided, what is confirmed across sources is that Booker’s jersey number has been No. 1 during his time with the Suns since his 2015 draft entry and that a number change is being reported to occur before the 2026-27 season.
