Overview of China's Mobile Prefix 135
The prefix 135 is a non-geographic mobile network code assigned within the People's Republic of China's national numbering plan, under the international country calling code +86. Unlike geographic area codes that correspond to specific cities or provinces, 135 identifies mobile services that are not tied to a fixed location. Subscribers using numbers beginning with 135 can be located anywhere in the country, and the prefix does not indicate the caller's or callee's physical region.
Technical Allocation and Numbering Structure
In China, mobile numbers are 11 digits long and follow the format: 1XX-XXXX-XXXX. The first three digits (e.g., 135) constitute the mobile network prefix, which is followed by an eight-digit subscriber number. The prefix 135 was originally allocated to China Mobile, one of the country's largest mobile network operators. However, due to Mobile Number Portability (MNP) regulations, a number starting with 135 may now be ported to another operator, such as China Unicom or China Telecom, while retaining the original prefix. Therefore, the prefix alone does not guarantee the current network operator.
Dialing and Formatting Guidelines
When dialing a Chinese mobile number from abroad, the international format must be used: +86 135 XXXX XXXX (or +86135XXXXXXXX). The leading '0' is not used in international dialing. From within China, callers simply dial the full 11-digit number without any trunk prefix, e.g., 135 XXXX XXXX. There is no area code involved, and the number is dialed the same way from any fixed or mobile phone across the country.
Regulatory and Operational Considerations
All mobile numbers in China, including those starting with 135, are regulated by the Ministry of Industry and Information Technology (MIIT) under the ITU-T E.164 international numbering standard. The numbers are used for both voice and SMS services, and support international roaming and interconnections with other networks. For businesses and individuals, it is essential to verify the current operator and service status of a 135 number, especially for SMS marketing or call center operations, as portability and anti-fraud measures may affect routing.
Practical Examples
- To call a 135 number from the United States: dial 011 86 135 XXXX XXXX.
- From a UK landline: dial 00 86 135 XXXX XXXX.
- From within China: simply dial 135 XXXX XXXX.
Understanding these details ensures accurate dialing and helps in identifying the nature of the number for business or personal communication.
