Soccer City, which hosted the 2010 Soccer World Cup final, will also play host to the 2023 Rugby World Cup final should South Africa's bid be successful.
South Africa, Ireland and France are the bidding countries and South Africa and France, who have both hosted the Soccer World Cup, have submitted bids that are technically very strong in areas like stadia.
Each country's submitted bid had to address seven areas, as set out by World Rugby.
All three countries will get an opportunity to address World Rugby's Council in person to explain their bid.
