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

Let’s say you’re calling a logistics partner in Kowloon or checking in with your dev team in Central. You pull up your dial pad — and pause. What’s the correct way to call a Hong Kong phone number from the United States? 

If you’re running a startup or small business navigating international communication, this guide is for you. From dialing instructions to choosing the most affordable phone system, here’s everything you need to know to call Hong Kong efficiently and cost-effectively. 

What’s the Hong Kong Country Code? 

The country code for Hong Kong is +852. You’ll need to dial this code after the US exit code whenever placing a call to Hong Kong. 

Unlike many other countries, Hong Kong doesn’t use regional area codes. All phone numbers are 8 digits long, and the prefix helps identify the type of service (landline or mobile). 

How to Call Hong Kong from the US, Step by Step 

Let’s walk through the process for both landlines and mobile numbers. 

For Hong Kong Landlines: 

1. Dial 011 – This is the US exit code. 
2. Dial 852 – The country code for Hong Kong. 
3. Dial the 8-digit local number (landline numbers usually start with 2 or 3). 

Example: To call (2345 6789), dial: 011-852-2345-6789. 

For Hong Kong Mobile Phones: 

1. Dial 011 (or use the “+” symbol on mobile). 
2. Dial 852. 
3. Dial the 8-digit mobile number (mobile numbers usually begin with 5, 6, 9). 

Example: To call (9123 4567), dial: 011-852-9123-4567 or on mobile: +852-9123-4567. 

Bonus Tip

On smartphones, long-press “0” to insert the “+” sign. This can replace the need to dial 011. 

Common Hong Kong Area Codes 

Hong Kong does not use area codes in the traditional geographic sense (like in the US or Canada). Instead, all phone numbers are 8 digits long, and the first digit of the phone number indicates the type of service which can be helpful for identifying whether the number is a landline, mobile, or other service. 

If you’re calling customers or partners in Hong Kong, you don’t need to worry about city-specific codes — just dial the full 8-digit number after the +852 country code. 

When Should SMBs Make International Calls? 

International rates vary depending on your provider. Traditional carriers can charge up to $0.50–$1.00+ per minute. That adds up fast, especially for small businesses managing teams, suppliers, or customers in Asia.
