Each year, bids are received by the Miss Universe organizers from organizations who wish to select the Miss Universe contestant for a country. This allows competition between different pageants to hold a country's license, as happened for Miss Italy and Miss France for example, when the licenses for their respective traditional organizations were revoked (the usual Miss France competition returned in 2004).

Usually a country's candidate selection involves pageants in major cities, with the winners competing in a national pageant, but this does not always occur. For example, in 2000 Australia's national pageant was abolished as a relic of a bygone era, with Australian delegates instead chosen by a modeling agency. Such "castings" are generally discouraged by the Miss Universe Organization, which prefers national pageants that preserve an aura of respectability and competition. Despite being "cast", Miss Australia, Jennifer Hawkins, was chosen as Miss Universe 2004. Later that year, Australia resumed its national pageant and chose Michelle Guy as Miss Universe Australia 2005.

Some of the most successful national pageants in the last decade have been Venezuela, USA, Puerto Rico, etc which command consistently high interest and television ratings in their respective countries. Recent arrivals in the pageant include China (2002), Albania (2002), Vietnam (2004), Georgia (2004), Ethiopia (2004), Latvia (2005), Kazakhstan (2006), Tanzania (2007) and Kosovo (2008); there have also been efforts to revive strong national pageants in South Africa, Canada, Spain, Japan, Colombia; Latin America among other regions. Prior powerhouses are Finland, Germany and Sweden. England is the most successful non-winning country with nine Top 5 positions.

There are continually efforts to expand the pageant, but the participation of some countries such as Algeria has proven difficult due to cultural barriers to the swimsuit competition, while others such as Mozambique, Armenia and Nepal have balked at sending representatives due to the cost (in fact, of all the major international pageants, the franchise fee for Miss Universe is the most expensive). As of 2007, only four countries have been present at every Miss Universe since its inception in 1952: Canada, France, Germany, and the United States. Many European countries allow 17-year-old contestants to compete in their pageants, while Miss Universe's minimum age is 18, so national titleholders often have to be replaced by their runners-up. Miss Universe also prohibits transsexual applicants and age fabrication.
