Postal codes in Malaysia
Wikimedia list article
Postal codes in Malaysia, usually referred to as postcodes (Malay: poskod), are five digit numeric.
The first two digits of the postcode denote the state or federal territory (e.g. 42000 Port Klang, Selangor). However, postcode area boundaries may cross state borders, as areas near to state borders may be served by post offices located in another state, and therefore use postcodes of the assigned post offices.
History
Malaysia's current postcode system was initiated by M. Rajasingam, director-general of Pos Malaysia from 1976 to 1986. In 1976, only addresses in Kuala Lumpur had postcodes. Wanting to expand the postcode system to the whole country, Rajasingam enlisted the help of the French postal authorities. The postcode system made the process of sorting out mail smoother, as it was easier for machines to recognise the numbers. In 2014, Rajasingam was honoured with the Darjah Panglima Jasa Negara (PJN), which carries the title of "Datuk", for his contributions to the postal service.
Areas
Listed below are the first 2 digits of codes assigned to each state and federal territory.
This brief starts where responsible research should: with the source description of “Postal codes in Malaysia” as wikimedia list article. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as wikimedia list article. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 9, 2026. The linked authority identifier is Q4263041. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1976, 1986 and 2014.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
