📍 Geographic Location of Chengdu/Ziyang/Meishan, Sichuan
Overview of Area Code +86 28
Area code 28 is the National Destination Code (NDC) assigned to the western Chinese metropolis of Chengdu, the capital of Sichuan Province, along with the adjacent prefecture-level cities of Ziyang and Meishan. Under the ITU-T E.164 international numbering plan, the full international dialing format for any fixed-line subscriber in this region is +86 28 XXXX XXXX (where the local subscriber number is eight digits long).
Geographic Coverage and Administrative Jurisdiction
The 028 numbering area encompasses the entire administrative territory of Chengdu (including districts such as Jinjiang, Wuhou, Qingyang, and the Tianfu New Area), as well as the urban and rural zones of Ziyang and Meishan. This allocation is managed by the Ministry of Industry and Information Technology (MIIT) of China and is used exclusively for geographic fixed-line services (PSTN and fixed VoIP). Mobile numbers in China are assigned separate non-geographic prefixes (e.g., 13x, 15x, 18x) and are not affected by area code 028.
Dialing Formats and Caller Instructions
For callers within China, dialing a fixed line in Chengdu requires the trunk prefix 0 followed by the area code and the eight-digit local number: 028 XXXX XXXX. For example, to call a Chengdu landline from Beijing, you would dial 028 8888 8888. For international callers, the country code for China is +86, so the same number is dialed as +86 28 8888 8888 (drop the leading 0).
Numbering Plan and Overlay Considerations
The local numbers within the 028 area are eight digits long, and there is no overlay code currently in effect; 028 is the sole area code for the region. However, due to the expansion of Ziyang and Meishan into the 028 numbering area (previously they had their own codes), all fixed-line numbers in these cities now use the 028 code, ensuring uniform dialing across the region.
Practical Implications for Businesses and Callers
For enterprises, having a Chengdu fixed-line number with area code 028 enhances local presence and customer trust. When marketing internationally, it is crucial to display the number in E.164 format: +86 28 XXXX XXXX. Callers from abroad should note that China uses the international access prefix 00 in most countries, but from North America, the exit code is 011. Therefore, a call from the US to Chengdu would be dialed as 011 86 28 XXXX XXXX. Always verify the current dialing rules with your telecom provider, as international dialing procedures may vary.
