What Is Aaron Judge's Jersey Number?
Aaron Judge wears 99 for the Yankees. It is a great trivia answer, and it happens to make one of the most collectible jersey numbers in the entire hobby.
Published August 11, 2026
Aaron Judge's jersey number is 99, worn for the New York Yankees his entire major-league career. Short answer done, but the story behind it, and what it means for card collectors, is the interesting part.
How Judge got 99
Judge was assigned 99 as a non-roster invitee in Yankees spring training in 2016. Teams routinely hand out high numbers to spring invitees, and most players trade them in for something lower once they make the roster. Judge kept it. After his 2017 Rookie of the Year season and his 2022 American League home run record, 99 became instantly associated with him, a rare case of a player making a "spring training number" iconic.

Why 99 is a collector's dream number
A serial-numbered card whose copy number matches the player's jersey number is a jersey match, one of the most predictable premiums in the hobby. So a Judge card numbered 99 out of any print run is his jersey match.
But Judge has something almost no other star has: 99 is also a very common print run. Cards numbered to /99 are everywhere. That sets up the 99/99 double jersey match, the 99th copy of a 99-card print run, where both the copy number and the print run equal his jersey number. It is the ultimate Judge chase card. See our double jersey match analysis for what that premium looks like (Judge is a big part of that data).

How to find an Aaron Judge jersey-match card
The catch: sellers almost never put the serial number in the listing title. They list "Aaron Judge Prizm /99" and leave the actual copy number in the photos, so searching titles for "99/99" turns up very little.
Serial Scout reads the serial off the listing photo, so you can search Aaron Judge by an exact numerator and jump straight to his 99 jersey matches or the rarer 99/99 double matches, instead of scrolling past hundreds of ordinary numbers.
