Buildings

The majority of offices as well as housing in Singapore are in high-rise buildings (e.g. HDBs, apartments, condominiums), and they all share the same address format.

[Block Number] [Street Name]
#[Unit Level]-[Unit Number] [Building Name]
Singapore [Postal Code]

(Side note: If you are unsure what an HDB is, it is a public housing unit by the Government of Singapore.)

The following example refers to a unit located on 101 Marlow Street in the Clife Building, at level 12 with unit number 05 (all example addresses in this post are dummy addresses):

101 Marlow Street
#12-05 Clife Parkview
Singapore 059020

Note that Singapore uses a 6-digit-number postal code.

From my personal experience, omitting a building name will typically not have a major impact in mail deliverability. Some HDBs might not have a building name, and it is acceptable to format the address as follows:

101 Marlow Street #12-05
Singapore 059020

Landed Properties

For landed properties, because there is no unit level, unit number, and building name, the second line from the address format above can be omitted completely:

[Unit Number] [Street Name]
Singapore [Postal Code]

For example:

60 Aria Street
Singapore 602580
