SZQuick Facts
SZAbout Shenzhen
Shenzhen is often called the "Silicon Valley of China" and the "Hardware Capital of the World". Designated as China's first Special Economic Zone in 1980, Shenzhen transformed from a fishing village of roughly 30,000 people into a megacity of over 17.5 million in just four decades — one of the fastest urbanizations in human history.
Shenzhen is the global headquarters for some of the world's largest technology companies, including Huawei, Tencent (makers of WeChat), DJI (drones), BYD (electric vehicles), ZTE, OnePlus, and Anker. The city is part of the Guangdong-Hong Kong-Macau Greater Bay Area, a massive economic zone with a combined GDP rivaling major nations.
Important: Although Shenzhen is directly adjacent to Hong Kong, they use completely different dialing codes. Shenzhen uses China's country code +86 with area code 755, while Hong Kong has its own country code +852 (no area code needed). They are separate telephone networks.
#What Does "86755" Mean?

Full format: +86 755 XXXX XXXX — this is how you write a Shenzhen landline number in international format. The "+" replaces whatever international exit code your country uses (011 from the US, 00 from the UK).

Shenzhen Mobile Numbers Do NOT Use 755
Mobile phones in Shenzhen do not use the 755 area code. Like all Chinese mobile numbers, Shenzhen mobile phones use the +86 1XX XXXX XXXX format (for example, +86 138 XXXX XXXX, +86 159 XXXX XXXX, +86 186 XXXX XXXX). The area code 755 is exclusively for landline and office phones. If you are trying to reach someone's mobile phone in Shenzhen, you need their +86 1XX number, not a 755 number.

BizBusiness Tips for Calling Shenzhen
WeChat is essential: WeChat (Weixin) is the primary communication tool for business in China. Most Shenzhen professionals prefer WeChat voice and video calls, messaging, and even document sharing over traditional phone calls or email.
English proficiency: As a global tech hub, many workers in Shenzhen's technology sector speak English, especially at companies like Huawei, Tencent, and DJI. However, Mandarin and Cantonese remain the dominant languages for everyday business.
Business hours: Standard office hours in Shenzhen are 9 AM - 6 PM CST, Monday through Friday. Many tech companies follow a "996" culture (9 AM to 9 PM, 6 days a week), but formal business calls should stick to standard hours.
Avoid these times: Lunch break (12-1 PM) and evenings after 9 PM are generally considered inappropriate for business calls. Also be aware of major Chinese holidays: Chinese New Year (January/February, 7-day holiday) and National Day Golden Week (October 1-7) effectively shut down business for a week or more.
