Area Code 316 – Langfang, Hebei

Overview of Area Code +86 316

Area code 316 is a geographic National Destination Code (NDC) within the Chinese numbering plan, assigned to Langfang (廊坊), a prefecture-level city in central Hebei Province. It serves the urban districts and surrounding counties, including Guangyang, Anci, and the county-level cities of Bazhou and Sanhe. Langfang is strategically located between Beijing and Tianjin, making it a significant economic and logistics hub.

Dialing Formats

When calling a fixed-line number in Langfang from within China, the trunk prefix 0 is used, followed by the area code and the subscriber number (typically 7 or 8 digits). The complete domestic format is 0 316 XXXX XXXX. For international callers, the country code +86 replaces the trunk prefix, yielding +86 316 XXXX XXXX. For example, a local Langfang number might be dialed as 0316-1234567 domestically or +86 316 1234567 from abroad. Note that the leading '0' is not included when dialing from outside China.

Geographic Coverage and Administration

The 316 area code covers approximately 6,429 square kilometers and administers a population of over 5 million. Key districts and counties include Guangyang District, Anci District, Xianghe County, Yongqing County, and Wen'an County. The code is managed under the Ministry of Industry and Information Technology (MIIT) of China, following ITU-T E.164 recommendations. Langfang's proximity to Beijing has led to significant development in technology parks and logistics centers, increasing demand for fixed-line services.

Calling Instructions

• Local calls within Langfang: If you are in the same city, you may dial the subscriber number directly without the area code, depending on your local exchange. However, it is safer to use the full domestic format.
• Domestic long-distance calls: Dial 0 + 316 + subscriber number.
• International calls to Langfang: Dial your country's exit code (e.g., 011 from the US), then 86, then 316, then the subscriber number. Do not include the '0'.
• Calling from a mobile phone: Simply dial 0316 + subscriber number, or +86 316 + subscriber number if using international format.

Overlay and Numbering Considerations

As of the latest updates, no overlay area code has been introduced for Langfang; the 316 code remains the sole geographic code for the region. Subscriber numbers are typically 7 or 8 digits, and the total length of a domestic national significant number (NSN) is 11 or 12 digits including the area code. For international calls, the NSN length is 10 or 11 digits (excluding the country code).

For businesses and individuals, it is essential to ensure that all published numbers include the correct area code to avoid misrouting. VoIP and mobile users should store numbers in international format (+86 316 ...) to ensure compatibility across networks.
