Source: "ICCA events by city in Argentina" tables in the Buenos Aires City Tourism Board's 2024 and 2025 reports. ICCA only counts international association meetings that rotate between countries: a city can host hundreds of meetings a year and few ICCA events.
Counting all meetings, not only international ones, the yearbook of Argentina's Economic Observatory of Meetings Tourism (2024 data) ranks the cities that hosted the most as follows:
- City of Buenos Aires: 29% of the country's meetings.
- Mar del Plata: 9.2% of the country's meetings.
- Córdoba: 8.6% of the country's meetings.
- Rosario: 5.2% of the country's meetings.
- Tucumán: 3.5% of the country's meetings.
- Salta: 2.9% of the country's meetings.

7. The whole country: the 2024 Yearbook
The ICCA ranking only counts international association meetings. For the whole country, the Argentina Meetings Industry Statistical Yearbook 2024, presented at the Meet Up Argentina launch (AOCA), reported:
- 3,641 meetings identified in 2024.
- 87.5% congresses and conventions and 12.5% trade fairs and exhibitions.
- 2,229,702 attendees (local, domestic and international) at congresses and conventions.

- By jurisdiction: City of Buenos Aires 29.7%, Buenos Aires Province 16.7%, Córdoba 15.2% and Santa Fe 9.3%.
8. How the ICCA ranking works
ICCA (International Congress and Convention Association) counts events that meet all of these criteria:
- At least 50 participants.
- Organised by international associations.
- Held on a regular basis.
- Rotating between at least three countries.
- Lasting half a day or more.
In 2025 only in-person and hybrid events were counted. Corporate events, brand launches and trade shows are not part of this ranking, even though they are also part of the meetings industry.
