Service 403 serves Pasir Ris Park with connections to Pasir Ris Int/MRT. However, on a daily basis, much of its demand comes from Pasir Ris Neighbourhoods 5, 6, and the private housing estates along Elias Road and Pasir Ris Road.

Formerly designated as a Parks service in 2005 (serving Pasir Ris Park and Sungei Api Api), it was reverted back to a normal trunk route in 2009.
