Quick Scoop: How Many Countries in G20?

If you’re wondering “how many countries in G20?” , the structure is a bit special.

  • 2 are regional organizations:
    • European Union (EU).

Why It’s Still Called “G20” If There Are 21 Members

This is where forum discussions and “latest news” angles come in.

  • The “20” in G20 is a historical brand name that stuck from when it was 19 countries plus just the EU.
  • With the AU joining, the practical head‑count rose to 21, but the name hasn’t changed; changing it would affect decades of branding, communiquĂ©s, and institutional references.
  • Recent 2024–2025 explainers and South Africa’s G20 presidency materials still refer to it as the G20 while listing both EU and AU as members.

A common way journalists phrase it now is: “The G20 comprises 19 countries, the European Union and the African Union.”
