Area Code 459 – Daqing, Heilongjiang

Overview of Area Code +86 459

Area code 459 is the National Destination Code (NDC) assigned to Daqing, a major prefecture-level city in the western part of Heilongjiang Province, China. Daqing is renowned for its petroleum industry, hosting the largest oil field in China. The code covers the entire administrative area of Daqing, including its urban districts (Sartu, Ranghulu, Longfeng, Honggang, Datong) and the surrounding counties (Zhaozhou, Zhaoyuan, Lindian, and Dorbod Mongol Autonomous County).

Dialing Formats

When calling a landline or fixed-line number in Daqing from within China, you must dial the trunk prefix 0 followed by the area code and the subscriber number. For example, a local number such as 1234567 would be dialed as 0459 1234567 from elsewhere in China. From outside China, callers should dial the international access prefix (e.g., 00 or +), then China's country code 86, followed by the area code 459 (without the leading zero) and the subscriber number: +86 459 1234567.

Geographic and Administrative Coverage

Daqing is a significant economic hub in Heilongjiang, with a population exceeding 2.7 million. The area code 459 is exclusively used for fixed-line services within this region. Mobile numbers in China are not tied to geographic area codes; they use separate prefixes such as 13x, 15x, 18x, etc., and are dialed without the area code. Therefore, when calling a Chinese mobile number, you simply dial the 11-digit mobile number preceded by +86.

Overlays and Numbering Changes

As of the latest ITU-T and MIIT (Ministry of Industry and Information Technology) records, there is no overlay code for Daqing. The area code 459 remains the sole NDC for fixed-line services in the region. However, due to the expansion of telecommunication services, some fixed-line numbers may have been migrated to VoIP or NGN (Next Generation Network) platforms, but the dialing format remains unchanged.

Caller Instructions

• Local callers within Daqing: For calls within the same area code, you can typically dial only the 7-digit subscriber number (without the area code). However, some operators may require the full 11-digit format (0 + area code + number) for all calls; check with your service provider.
• Domestic long-distance callers: Dial 0 + 459 + subscriber number.
• International callers: Dial your country's exit code (e.g., 00, 011) + 86 + 459 + subscriber number. Do not include the leading '0' of the area code.

For accurate billing and connection, always verify the subscriber number length, as fixed-line numbers in Daqing are 7 digits. If you are calling from a mobile phone within China, you can also use the +86 format, but the leading 0 is still required when dialing a fixed line from a mobile phone.
