Overview of Area Code +86 550
The country calling code +86 belongs to China, and the area code 550 is the National Destination Code (NDC) assigned to the city of Chuzhou in Anhui Province. Chuzhou is a prefecture-level city located in the eastern part of Anhui, bordering Jiangsu Province. It serves as an important transportation hub and industrial center, with a population of over 4 million. The area code 550 covers the entire administrative region of Chuzhou, including its urban districts (Langya, Nanqiao) and surrounding counties such as Lai'an, Quanjiao, Dingyuan, Fengyang, and Tianchang (county-level city).
Dialing Formats
When calling a fixed-line number in Chuzhou from within China, you must dial the area code followed by the local 7-digit subscriber number. The complete national format is 0550 XXXX XXX. For example, a local number might be dialed as 0550 123 4567 from other parts of China. If you are calling from outside China, you need to use the international prefix (usually 00 or +), then China's country code 86, followed by the area code without the leading zero. Thus, the international format becomes +86 550 123 4567. Note that the trunk prefix '0' is only used for domestic calls within China.
Geographic and Administrative Details
Chuzhou is strategically located on the northern bank of the Yangtze River Delta, adjacent to Nanjing, the capital of Jiangsu Province. This proximity has spurred economic development and increased telecommunication traffic. The area code 550 is exclusively for fixed-line services (PSTN). Mobile numbers in China are assigned separate non-geographic prefixes (e.g., 13x, 15x, 18x) and are not tied to this area code. Overlay plans have not been implemented for Chuzhou; the 550 code remains the sole area code for the region.
Caller Instructions
For local callers within Chuzhou, dialing the 7-digit subscriber number alone is sufficient for calls within the same city. For long-distance calls from other Chinese cities, dial 0 followed by 550 and the subscriber number. International callers should replace the leading zero with the +86 country code, so the sequence becomes +86 550 followed by the 7-digit number. Ensure that you omit the leading '0' of the area code when dialing from abroad.
