Twelve stadia were selected to host the World Cup matches. During the tournament, many of them were known by different names, as FIFA prohibits sponsorship of stadia unless the stadium sponsors are also official FIFA sponsors. For example, the آلیانز آرنا in Munich was known during the competition as FIFA World Cup Stadium, Munich (FIFA WM-Stadion München), and even the letters of the company Allianz were removed or covered. Some of the stadia also had a lower capacity for the World Cup, as FIFA regulations ban standing room; nonetheless, this was accommodated as several stadia had a UEFA five-star ranking. The stadia in Berlin, Munich, Dortmund and Stuttgart hosted six matches each, while the other eight stadia hosted five matches each.
