How to Call Singapore from the US: A Guide for SMBs and Startups

Imagine this: you’re closing a deal with a tech distributor in Singapore or syncing with a remote team member working out of Marina Bay. You pick up the phone — then pause. What’s the right format to dial Singapore from the United States? 

If you’re an SMB or startup with global presence, this guide walks you through everything you need to know — from dialing formats and international codes to affordable tools that make cross-border calls smooth and professional. 

What’s the Singapore Country Code? 

The country code for Singapore is +65. You’ll need to use this code anytime you dial into Singapore from another country, including the United States. 

Why it matters: Singapore is a strategic business hub in Southeast Asia, with growing ties to American startups and tech service providers. Whether you're coordinating across time zones or onboarding a partner in Singapore, knowing how to dial correctly avoids friction and wasted time. 

How to Call Singapore from the US, Step by Step 

Calling Singapore is refreshingly simple—there are no area codes, and all phone numbers are 8 digits long. The main difference lies in whether you're calling a landline or a mobile number. 

For Singapore Landlines: 

1. Dial 011 – The US exit code 
2. Dial 65 – The Singapore country code 
3. Dial the 8-digit landline number 

Example: If the landline number is 6123-4567, dial 011-65-6123-4567. 

For Singapore Mobile Numbers: 

1. Dial 011 (or use + on a mobile phone) 
2. Dial 65 
3. Dial the 8-digit mobile phone number 

Example: If the mobile number is 9123-4567, dial 011-65-9123-4567. Or simply: +65-9123-4567. 

Pro tip:  

On smartphones, you can long-press “0” to insert a “+” symbol. This can replace the US exit code (011), making it easier to dial international numbers on the go. 

Common Singapore Area Codes 

Singapore does not use regional area codes like many other countries. All phone numbers, whether mobile or landline, are 8 digits long and begin with specific leading digits that indicate the type of service (not geographic location).

When Should SMBs Make International Calls? 

Startups and small businesses based in the US may call Singapore for many reasons: 

• Managing offshore development or engineering teams 
• Partnering with Singapore-based vendors or agencies 
• Supporting Southeast Asian customers or resellers 
• Exploring market expansion in APAC 

Time zone tip: Singapore operates on Singapore Standard Time (SST), which is 12 to 15 hours ahead of US time zones, depending on where you're located. 

How Much Does It Cost to Call Singapore? 

Costs vary based on your calling provider. Traditional phone companies may charge $0.20 to $0.60 per minute or more. Those fees can climb quickly, especially for frequent calls.
