Area Code 552 – Bengbu, Anhui

Overview of Area Code +86 552

Area code 552 is a geographic National Destination Code (NDC) assigned to Bengbu City (蚌埠市) in Anhui Province, People's Republic of China. Under the ITU-T E.164 international numbering plan, the full international dialing format for a fixed-line number in Bengbu is +86 552 XXXX XXXX, where +86 is the country calling code for China, 552 is the area code, and the subscriber number is eight digits long. Domestically, callers within China dial 0552 XXXX XXXX, omitting the international access prefix.

Geographic Coverage and Administrative Jurisdiction

The 552 numbering area encompasses the entire prefecture-level city of Bengbu, including its four urban districts (Longzihu, Bengshan, Yuhui, and Huaishang) and three counties (Huaiyuan, Wuhe, and Guzhen). As a geographic code, 552 is tied to the PSTN infrastructure of this region, and numbers are allocated to fixed-line services, including residential, business, and government lines. The code does not cover mobile services; all Chinese mobile numbers use the non-geographic prefixes 13x, 14x, 15x, 16x, 17x, 18x, and 19x.

Dialing Formats and Caller Instructions

• Local calls within Bengbu: For calls within the same area code, subscribers typically dial only the 8-digit subscriber number (e.g., 1234 5678). However, some legacy exchanges may require the full 11-digit domestic format (0 + area code + number) depending on the local dialing plan.
• Domestic long-distance calls from other Chinese cities: Dial the domestic trunk prefix 0, then the area code 552, followed by the subscriber number. Example: 0552 1234 5678.
• International calls from outside China: Dial the international access prefix (e.g., 00 from most countries, or + from mobile), then the country code 86, the area code 552 (without the leading 0), and the subscriber number. Example: +86 552 1234 5678.
• Calls from mobile phones: Mobile callers within China can dial the domestic format (0552...) or, if the phone supports it, the international format (+86 552...) for clarity.

Overlay and Numbering Plan Considerations

As of the latest ITU-T and MIIT (Ministry of Industry and Information Technology) updates, there is no overlay code for Bengbu; 552 remains the sole area code for the region. The subscriber number length is fixed at eight digits, following the national standard for Chinese fixed-line numbers. No permissive dialing or 10-digit dialing is required, but users should always verify the current local dialing rules with their service provider, as some areas have implemented mandatory 11-digit dialing for all calls.
