Petaling Jaya is divided into several sections. Some sections themselves are subdivided into smaller neighbourhoods (kejiranan), for example SS5D. Some sections have their own names (SS1 is Kampung Tunku), while other sections are grouped together (SS4, SS5, SS6, and SS7 are part of Kelana Jaya).
These sections names are used in the addressing format for locations in Petaling Jaya.
No. 15,
Jalan SS20/6,
47300 Petaling Jaya,
Selangor.
This system would point to house number xx, 5th street, section SS3, Petaling Jaya. This would remove the need to have an additional address line for the housing estate name (in this example, Taman Subang) like most addresses used for the rest of the country.
The city sections are numbered as such that the older sections have no prefixes to their section number (Seksyen 1, Seksyen 9) while later sections have prefixes such as SS (Sungei Way-Subang), PJS (Petaling Jaya Selatan) and PJU (Petaling Jaya Utara).
Note: The missing neighborhood between SS11 and SS20 (SS12 - SS19), are within Subang Jaya, under the jurisdiction of the Subang Jaya Municipal Council
Note:* PJU 9 ( Bandar Sri Damansara ) the only section / township in Petaling Jaya is using the same postcode of Kuala Lumpur.
Note *: Only eastern part of PJS7 is under the jurisdiction of the Petaling Jaya City Council. The remaining part of PJS7 together with PJS9 and PJS11 ( Southern part of Bandar Sunway ) are within Subang Jaya, under the jurisdiction of the Subang Jaya Municipal Council
