How to Call a Landline in Singapore
Calling a Singapore landline from the United States is straightforward, as Singapore has a simple numbering system:
- Dial the US exit code: 011
- Dial Singapore’s country code: 65
- Dial the local 8-digit phone number
For example, if you’re calling a Singapore landline number 6123 4567, you would dial 011 65 6123 4567 from the United States.
Singapore’s telephone numbering system is unique in that it doesn’t use area codes. The entire country shares the same international dialing code (65), and all phone numbers are 8 digits long.
How to Call a Mobile Phone in Singapore
Calling a Singapore mobile phone follows exactly the same pattern as calling a landline:
- Dial the US exit code: 011

- Dial the full 8-digit mobile number
For example, if the Singapore mobile number is 8123 4567, you would dial 011 65 8123 4567 from the US.
Mobile phone numbers in Singapore typically begin with 8 or 9. Some newer numbers may start with 6, though this prefix was traditionally reserved for landlines.

Time Difference
Singapore follows Singapore Standard Time (SST), which is UTC+8 all year round. Singapore does not observe Daylight Saving Time.
The time difference between the US and Singapore is substantial:

This significant time difference means careful planning is needed for real-time communication. When it’s morning in the US, it’s evening or night in Singapore.
