European Qual group stage draw will take place on Dec 13th.
All teams in each group won't be known yet at the draw since Nations League playoffs are not concluded by then.
"Qualifiers begin in March 2025 and end with the play-offs in March 2026. Teams will be drawn into 12 groups of four and five teams. Teams drawn in groups of five will begin qualifying in March and teams drawn in groups of four start their campaigns in September. All groups conclude in November 2025."
"The 12 group winners qualify directly for the World Cup. The 12 group runners-up participate in the play-offs, along with the four best-ranked group winners of the 2024/25 UEFA Nations League that did not finish their European Qualifiers group stage in first or second place."
