What is a white card in soccer?

In soccer, a white card does not exist as an official card or disciplinary action. The primary disciplinary cards used in soccer are yellow and red cards. However, some unofficial variations of the game have introduced alternative colored cards as a way to manage behavior and enforce fair play.

These unofficial variations, commonly played at youth levels or in casual games, may assign a white card as a warning before issuing a yellow or red card. The idea behind a white card is to provide players with an opportunity to rectify their behavior before facing more severe consequences.

It is important to note that the white card is not recognized or implemented in professional soccer leagues or official competitions governed by organizations such as FIFA or UEFA. Therefore, it is not a commonly known or used card in the sport.
