Area Code 543 – Binzhou, Shandong

Overview of Area Code +86 543

Area code 543 is a geographic National Destination Code (NDC) assigned to Binzhou (滨州), a prefecture-level city located in the northern part of Shandong Province, China. Under the ITU-T E.164 international numbering plan, the full international dialing format for fixed-line numbers in Binzhou is +86 543 XXXX XXXX, where the subscriber number is eight digits long. Domestically, callers within China dial 0543 XXXX XXXX (trunk prefix 0 followed by the area code and subscriber number).

Geographic Coverage and Administrative Jurisdiction

Binzhou administers one district (Bincheng), two counties (Zhanhua, Yangxin), and two county-level cities (Zouping, Huimin). The 543 code covers all landline services within these administrative boundaries, including the urban center and surrounding rural areas. The city lies along the Yellow River delta, bordering Dongying to the east and Dezhou to the west.

Dialing Procedures

• Local calls (within Binzhou): For calls between landlines in the same area, dial the 8-digit subscriber number directly (no area code required).
• Domestic long-distance calls (from other Chinese cities): Dial 0543 followed by the 8-digit subscriber number. For example, to call a Binzhou landline from Beijing, dial 0543 XXXX XXXX.
• International calls (from outside China): Dial your country's international access code (e.g., 011 from the US, 00 from most European countries), then 86 543, followed by the 8-digit subscriber number. For instance, a caller in the United States would dial 011 86 543 XXXX XXXX.

Numbering and Overlay Considerations

As of the latest ITU-T national numbering plan updates, Binzhou does not have an overlay code; 543 remains the sole geographic area code for the city. Subscriber numbers are 8 digits long, and the total length of a national significant number (NSN) is 12 digits (including the leading 0 for domestic calls). No recent changes to the numbering plan have been announced for this region.

Important Notes for Callers

• Mobile numbers in China begin with 1 (e.g., 13X, 15X, 18X) and are not tied to geographic area codes; therefore, they are not reached via 543.
• When calling from abroad, ensure you replace the domestic trunk prefix 0 with the country code 86. Omitting the +86 or 86 will result in a failed call.
• Some VoIP and internet-based services may route calls to Binzhou landlines using alternative access numbers, but the standard E.164 routing remains +86 543.
