📍 Geographic Location of Mianyang, Sichuan
Overview of Area Code +86 816
Area code 816 is a geographic National Destination Code (NDC) assigned to Mianyang, a prefecture-level city in the central-western part of Sichuan Province, China. Mianyang is the second-largest city in Sichuan and serves as a major industrial and scientific hub, often referred to as the 'Science and Technology City' due to its numerous research institutes and electronics industries. The area code covers the entire administrative jurisdiction of Mianyang, including its central urban districts (Fucheng, Youxian, Anzhou) and its surrounding counties and county-level cities (e.g., Santai, Yanting, Zitong, Pingwu, Beichuan, and Jiangyou).
Dialing Formats
When calling a fixed-line subscriber in Mianyang from within China (excluding the local area), the domestic trunk prefix 0 is used, followed by the area code and the subscriber's 7-digit local number. The complete domestic format is: 0 816 XXXX XXXX (where X represents the local number digits). For example, a local number 1234567 would be dialed as 0816 1234567 from other Chinese cities.
For international callers, the country code for China is +86. The leading '0' of the domestic trunk prefix is omitted. Therefore, the international dialing format is: +86 816 XXXX XXXX. For instance, to reach the same number from abroad, you would dial +86 816 1234567.
Local Calling and Overlays
Within Mianyang itself, local calls are made by dialing only the 7-digit subscriber number, without the area code. As of the latest numbering plan updates, Mianyang has not implemented an overlay code; the 816 code remains the sole geographic code for the region. However, due to the expansion of telecommunication services, some numbers may be assigned to VoIP or other non-geographic services, but the geographic allocation remains primarily for fixed-line PSTN services.
Caller Instructions
- Local callers (within Mianyang): Dial the 7-digit local number directly.
- Domestic long-distance callers (from other Chinese cities): Dial 0 816 followed by the 7-digit local number.
- International callers: Dial your country's exit code (e.g., 011 from the US, 00 from many countries), then 86 816, followed by the 7-digit local number.
It is important to note that mobile numbers in China have their own prefixes (e.g., 13x, 15x, 18x) and are not dialed with the 816 area code. When calling a Mianyang fixed line from a mobile phone, the same trunk prefix rules apply.
