Area Code 570 – Quzhou, Zhejiang

Overview of Area Code 570 (Quzhou, Zhejiang)

Area code 570 is a geographic National Destination Code (NDC) assigned to Quzhou, a prefecture-level city in the western part of Zhejiang Province, People's Republic of China. Under the ITU-T E.164 international dialing standard, the full country calling code for China is +86. Therefore, to reach a fixed-line subscriber in Quzhou from abroad, you would dial +86 570 XXX XXXX (or +86570 followed by the local 7-digit subscriber number). Within China, the domestic trunk prefix is 0, so calls from other Chinese cities require dialing 0570 followed by the local number. Local calls within Quzhou (and its surrounding counties) may be dialed using only the 7-digit subscriber number, depending on the current local dialing plan.

Geographic Coverage and Administrative Jurisdiction

The 570 area code covers the entire administrative territory of Quzhou City, which includes the urban districts of Kecheng and Qujiang, as well as the county-level cities of Jiangshan and the counties of Longyou, Changshan, and Kaihua. Quzhou is situated at the junction of Zhejiang, Jiangxi, Anhui, and Fujian provinces, serving as a regional transportation hub. The area code is used for all fixed-line (PSTN) services, including traditional analog lines, ISDN, and VoIP-based fixed telephony that is registered to a physical address within the Quzhou numbering area.

Dialing Formats and Caller Instructions

For international callers, the correct format is: +86 570 XXX XXXX. For example, a local Quzhou number 1234567 would be dialed as +86 570 1234567 from outside China. For domestic callers outside Quzhou, the format is 0570-XXXXXXX. It is important to note that the leading 0 is a trunk prefix and is not included when dialing from abroad; only the country code 86 and the area code 570 are used. Within Quzhou, if you are calling a number in the same local calling area, you may be able to dial just the 7-digit subscriber number, but this practice is becoming less common as China moves toward uniform 10-digit dialing for fixed lines. Always check with your service provider for the most current local dialing procedures.

Overlays and Numbering Plan Considerations

As of the latest ITU-T national numbering plan updates, there are no overlay area codes for Quzhou; the 570 code is exclusively used for the geographic region. However, the rapid growth of telecommunications services has led to an increased demand for numbers, and the Chinese Ministry of Industry and Information Technology (MIIT) periodically reviews numbering resources. If an overlay were introduced, it would require 10-digit dialing for all local calls. For now, the 7-digit subscriber number remains the standard within the 570 area code.

For businesses and individuals, it is essential to ensure that your telecommunications provider correctly routes calls to Quzhou using the proper prefix. Misrouting can occur if the area code is confused with other similar codes, such as 571 (Hangzhou) or 575 (Shaoxing). Always verify the complete number before dialing.
