Area Code 752 – Huizhou, Guangdong

Geographic Coverage and Administrative Jurisdiction

The area code 752 is a geographic National Destination Code (NDC) assigned to Huizhou, a prefecture-level city in the eastern part of Guangdong Province, China. Huizhou is strategically located in the Pearl River Delta, bordering Dongguan to the southwest, Shenzhen to the south, and Heyuan to the northeast. The city administers two urban districts (Huicheng and Huiyang), three counties (Huidong, Boluo, and Longmen), and two national-level development zones. The area code covers all landline telephone numbers within these administrative boundaries.

Dialing Formats and Caller Instructions

For local callers within Huizhou, the area code is typically omitted when dialing a fixed-line number; only the 7-digit subscriber number is required. However, for calls originating from outside Huizhou but within China, the full national format must be used: 0752 XXXX XXX (where X represents the 7-digit local number). International callers should dial +86 752 XXXX XXX (or the appropriate international prefix from their country, e.g., 011 from the US, followed by 86 752...).

It is important to note that China's numbering plan does not use trunk prefixes in the international format; the leading '0' of the area code is dropped when adding the country code. Thus, the international format is +86 752, not +86 0 752.

Overlay and Numbering Considerations

Currently, Huizhou does not have an overlay area code; 0752 remains the sole geographic code for the region. The subscriber numbers are 7 digits long, and the total length of a national significant number (NSN) for a fixed-line in Huizhou is 11 digits (including the leading 0). This structure aligns with China's closed numbering plan, where the NSN is always 11 digits for fixed and mobile services.

Practical Usage and Routing

When calling a Huizhou fixed line from a mobile phone within China, the area code is mandatory. For example, to call a business in Huizhou from Beijing, one would dial 0752 1234567. From abroad, a caller would dial +86 752 1234567. The same format applies for VoIP and internet-based calling services, ensuring proper routing through the PSTN.

As part of the Guangdong province's telecommunications infrastructure, Huizhou's fixed-line network is fully integrated with the national and international switching systems, providing reliable voice and fax services. Businesses operating in Huizhou often list their numbers in international directories with the +86 752 prefix to facilitate global communication.
