Area Code 577 – Wenzhou, Zhejiang

Geographic Coverage and Administrative Jurisdiction

The +86 577 country and area code combination is the international dialing prefix for the city of Wenzhou, a prefecture-level city in the southeastern coastal province of Zhejiang, China. Wenzhou is a major economic hub, known for its manufacturing industries, including footwear, electrical equipment, and packaging. The 577 area code serves the entire Wenzhou administrative region, which includes the central urban districts (Lucheng, Longwan, Ouhai) and the surrounding county-level cities and counties such as Yueqing, Rui'an, Yongjia, Wencheng, Pingyang, Taishun, and Dongtou.

Dialing Formats and Procedures

For callers within China (domestic calls), the area code 577 is dialed with a leading 0: 0577. For example, to call a landline in Wenzhou from another city in China, you would dial 0577 followed by the 7-digit local subscriber number. For international callers, the format is +86 577 followed by the 7-digit local number (drop the leading 0). For instance, a call to a Wenzhou landline would be dialed as +86 577 XXXXXXX (where XXXXXXX represents the 7-digit subscriber number).

Numbering Structure and Overlays

Wenzhou uses a closed numbering plan. Local numbers are 7 digits long, making the total length of a domestic number (including the 0 and area code) 11 digits. No overlay area codes have been introduced for Wenzhou; the 577 code is exclusively assigned to this region. However, due to the proliferation of mobile phones, many numbers starting with 577 may also be encountered as part of mobile numbers, but mobile numbers in China are always 11 digits long and begin with 1 (e.g., 138, 159). Therefore, a number beginning with 577 after the country code is always a fixed-line number.

Caller Instructions

For local callers within Wenzhou: you can dial the 7-digit local number directly without the area code. For callers from other regions in China: dial 0577 + 7-digit local number. For international callers: dial your country's exit code (e.g., 00 from most countries, or 011 from the US/Canada), then 86, then 577, then the 7-digit local number. Ensure you omit the leading 0 of the domestic area code when dialing from abroad.

Important Considerations

When calling Chinese landlines, be aware that some numbers may be used for fax or data lines. Also, due to number portability, a fixed-line number may be routed to a mobile phone, but the dialing format remains the same. For businesses, having a Wenzhou landline number can establish a local presence, but many companies also use 400 numbers for national customer service.
