Accreditation is a mandatory process to register all athletes and officials to the World Games 2009 Kaohsiung. Through Online accreditation system, each international sport federation will be able to enroll all the athletes and officials before the deadline.

Accreditation Center is located in the main lobby of the Kaohsiung City Hall, where each registered participant and official will receive an Identity and Accreditation Card, a counterfeit-proof pass equipped with special security features, authorizing each participant access to specific events or services.

The entire accreditation process is provided in detail in the World Games 2009 Kaohsiung Bulletin.
