Internet fan forums, in particularly, the BigSoccer forum, had narrowed down his numbers to 9, 17 and 18, while some wondered if there were numbers for the World Cup team. Contrary to the latter belief, it is confirmed through pictures and footage that numbers "were" used, however, there was no mention of numbers worn during that year at the American Soccer History Archives, nor is it in the official game reports of FIFA. The National Soccer Hall of Fame has recorded the number as 18, from an alleged report from Walter Bahr, a member of that World Cup squad, who does not recall stating such a number. He offers his highest doubts and argues that strikers usually wore number 9, as numbers were given based on position and Gaetjens was a striker. He also attests that only two substitutes would receive numbers, skipping 13, which was considered bad luck, while numbers stopped at 14, before no longer being included. He mentions that it is possible that number 9 was taken, as Gaetjens was a late addition along with two others but ultimately, the squad grew to only 16 players.
