How to fill up Singapore addresses correctly

Many people in Singapore struggle to fill up their shipping addresses properly. A wrongly-formatted address increases the chance of a failed delivery, and also adds unnecessary workload on our postal delivery staff. This guide provides an exhaustive guide on how you should be filling your shipping address to ensure that it gets delivered. 

The standard address format

Singapore's address format is straightforward: 

[Block number] [Street number]
[Apartment unit number]
Singapore [Postal code] 

Do note that the "City" field in all Singapore addresses should always be "Singapore". We don't use district names for Singapore addresses. 

HDB addresses

A unit number is required for all HDB addresses. 

Here's an example of a correct HDB address: 

Blk 111 Hougang St 1 
#01-111
Singapore 111111

Here's an example of a WRONG HDB address (missing the unit number):

Blk 111 Hougang St 1
Singapore 111111

Here's an example of a WRONG HDB address (always put the block number before the street number, and put the unit number in the separate "Apartment, suite, etc." field):

Hougang St 1 Blk 111 #01-111
Singapore 111111

Here's an example of a WRONG HDB address (using something other than "Singapore" in the "City" field):

Blk 111 Hougang St 1
#01-111
Hougang 111111

Condo addresses

A unit number is required for most condo addresses. On top of that, you may also include the condo name in the "Apartment, suite, etc." field. 

Here's an example of a correct condo address: 

111 Hougang St 1 
Rainbow Residences, #01-111
Singapore 111111

Landed property addresses

A unit number is usually not required for landed properties. 

Here's an example of a correct landed property address: 

No. 29 Hougang St 99
Singapore 111111


If you're still not sure how to fill in your Singapore address properly, these documents should have your address written in the proper format: 

  • Your bills (electricity, telecom, gas, etc.)
  • Your bank statements 
  • Your lease agreement (if you're a tenant at a rental house)
  • Your identity card
