What does the operator's secondary sales number mean?

The operator's secondary sales number has the following meanings:

Operator's secondary sales number refers to the number that is recycled by telecom operators and resold. Because the telephone number itself is limited, operators will regularly recycle unused numbers such as downtime or arrears for secondary sales. In other words, some new users may use old numbers that others have used.

An operator refers to a provider that provides network services. Huawei, ZTE, Nokia, Ericsson and other communication equipment manufacturers are called manufacturers, while China Mobile, China Unicom, China Telecom and China Radio and Television are called operators. Because the country is very strict in telecommunications management, only companies with operating licenses issued by the Ministry of Industry and Information Technology can set up networks.
