Area Code 310 – Handan, Hebei

Overview of Area Code +86 310

Area code 310 is a geographic National Destination Code (NDC) assigned to Handan, a prefecture-level city in the southern part of Hebei Province, China. When dialing from abroad, the full international format is +86 310 XXXX XXXX, where the local subscriber number is eight digits long. Within China, callers outside Handan dial 0310 XXXX XXXX, while local calls within Handan can often be made using just the eight-digit subscriber number, depending on the operator's local dialing rules.

Geographic Coverage and Administrative Jurisdiction

The code covers the entire administrative area of Handan, including its urban districts (such as Hanshan, Congtai, Fuxing, and Fengfeng Kuang) and the surrounding counties and county-level cities (including Handan County, Linzhang, Cheng'an, Daming, Shexian, Ci County, Feixiang, Yongnian, Qiu County, Jize, Guangping, Guantao, Wei County, Quzhou, and Wu'an). Handan is one of the most populous cities in Hebei and serves as a regional economic and transportation hub.

Dialing Formats and Instructions

• International dialing: From any country, dial the international access prefix (e.g., 011 from the US, 00 from most European countries), then 86 (China's country code), followed by 310 and the eight-digit local number. Example: +86 310 1234 5678.
• Domestic long-distance: From other Chinese cities, dial 0 (trunk prefix) + 310 + the eight-digit subscriber number. Example: 0 310 1234 5678.
• Local calls: Within Handan, you may dial the eight-digit number directly without the area code, but some fixed-line operators may still require the area code. Check with your local service provider.

Numbering Plan and Overlay Considerations

China's numbering plan follows ITU-T E.164 recommendations. The length of a complete national significant number (NSN) for geographic numbers is typically 11 digits (excluding the trunk prefix 0), which includes the area code and the subscriber number. Handan's area code is 310, and subscriber numbers are eight digits, resulting in an NSN of 11 digits. As of the current plan, there is no overlay code for Handan; 310 is the sole geographic area code for the city. However, with the growth of telecommunication services, future overlays are possible, but they would not affect the existing dialing procedures.

Caller Instructions

For callers within China, always include the trunk prefix 0 when dialing from outside the area. For international callers, omit the trunk prefix and use the country code +86 instead. Ensure you have the correct eight-digit local number, as numbers in Handan are not portable across geographic areas; they are tied to the physical location of the fixed line.
