Frequently Asked Questions

Can a phone number's location change?

The registered location of a phone number is fixed at assignment and never changes. Even when you port your number to another carrier through Mobile Number Portability, the location information remains the same.

Why can't I find location info for virtual carrier numbers?

Virtual carriers (like Xiaomi Mobile, Ali Telecom) use number ranges assigned by major carriers, but their prefix allocation information may not be included in public databases, resulting in incomplete query results.

Does number portability change the registered location?

Number portability only changes the carrier, not the registered location. Your phone number still belongs to the original province and city.

Chinese Mobile Number Coding Rules

Chinese mobile numbers are 11 digits following the E.212 numbering plan. The first 3 digits identify the carrier, digits 4-7 (HLR code) identify the local exchange, and digits 8-11 are the subscriber sequence number.

As mobile number resources become scarce, MIIT continuously allocates new prefixes. The three major carriers now have dozens of prefixes, and virtual operators have also been granted使用权 for some number ranges.
