GD Express Sdn Bhd (GDex) was formed in 1997 to provide express delivery service for both the domestic and international markets. It operates a network of 96 stations, comprising 53 branches, 2 affiliate stations and 41 agents throughout East and West Malaysia. GDex has a fleet of more than 280 trucks and vans used primarily for hauling of documents and parcels between stations and the National Hub (termed "line-haul" fleet) for local pick-ups and deliveries. The company's express delivery service operations are structured along the principles of the "Hub and Spoke" concept whereby customers' packages are collected by the branches, sent by trucks to a Central Clearing Hub for sorting and then redirected to their ultimate destinations. The group currently employs more than 1300 staff.

GDex is the first local express delivery company to obtain ISO 9001: 2000 (Quality Management System) certification for all its entire 25 departments in 2003. In November 2009, GDex upgraded its (Quality Management System) to ISO 9001: 2008. In its quest to be a world class service provider, the company has embarked on a world class excellence training programme called the Prime Minister Quality Award programme (PMQA) to equip its employees for world class performance in express carrier service and operations.

GDex is listed on the Mesdaq market of Bursa Malaysia through its holding company GD Express Carrier Bhd in May 2005.
