Aaron Judge wears uniform number 99 with the New York Yankees. The number has become one of the most recognizable jersey numbers in modern baseball because of Judge’s extraordinary home-run production and stature.
Judge wore 99 when he reached the majors with New York in 2016, and he kept it as his career developed. He is the only player in Major League Baseball history to wear number 99, according to the Yankees’ retired-number context and widely cited uniform records. The choice also fits his larger-than-life image: Judge is listed at 6 feet 7 inches, making both his build and his jersey easy for fans to recognize.
The number is sometimes confused with notable Yankees numbers such as 2, worn by Derek Jeter, or 44, worn by Reggie Jackson and retired by the club. Number 27 is associated with other baseball stars, but it is not Judge’s Yankees number. Judge’s No. 99 remained his identifier during the 2026 season, including the period surrounding his rib injury and subsequent return.
