国际足联（FIFA）：2025年球员身份和转会规定-包括临时监管框架报告（英文版）

Each association must have an electronic player registration system, which must assign each player a FIFA ID when the player is first registered. A player must be registered at an association to play for a club as either a professional or an amateur in accordance with the provisions of article 2.
