Each of the telecommunication enterprise’s application for the allocation of the special number is limited to one special number.

Only the telecommunications enterprise allocated with signaling point codes may apply to the competent authority for the allocation of subscriber numbers.

When a telecommunications enterprise applies to the competent authority for the allocation of subscriber numbers, it shall submit the following documents：
1. Telecommunications Number Application Form
2. Subscriber number usage plan（Subscriber growth forecast data, network structure and capacity planning data）
3. Number of subscribers（exempt for the first-time applicant）
4. Sampling inspection report from an institution with public credibility（exempt for the first-time applicant）
5. Relevant supporting documents of the telecommunications enterprise registration
6. Other materials designated by the competent authority
The sampling inspection report from an institution with public credibility prescribed in Subparagraph 4 of the preceding paragraph refers to the sampling verification report of the number of subscribers issued by two persons with the expertise of science, engineering, commerce or management who are registered in the talent database of the Public Construction Commission, Executive Yuan.

The competent authority should consider the following matters when reviewing the application for subscriber number allocation prescribed in the previous article：
1. Whether the type of the applied telecommunication numbers is necessary to provide services
2. Whether the number of subscriber numbers reaches the minimum usage standard（Annex 2）
3. Whether it includes subscriber growth forecast for more than three months in the future
4. Whether it specifies the structure of subscribers’ access to the network and the connection structure with other telecommunications networks
5. Whether it specifies the brand, model, quantity, capacity and function of the switch

The calculation method for the number of allocation for the application of subscriber numbers, the utilization rate of re-application and the application’s quantity limit are as follows：
1. Local line phone number：It takes ten thousand numbers as a unit. For the first- time application, ten units are the cap for each area. The utilization rate should be more than 50% before it can be applied again, with five units as the cap each time.
2. Mobile phone number：It takes a hundred thousand numbers as a unit. For the
first-time application, ten units are the cap. The utilization rate should be more than 70% before it can be applied again, with five units as the cap each time.
3. Satellite communication number：It takes ten thousand numbers as a unit. Ten units are the cap for each application. The utilization rate should be more than 70% before it can be applied again.
4. Internet phone number：It takes ten thousand numbers as a unit. For the first-time application, twenty units are the cap. The utilization rate should be more than 70% before it can be applied again, with ten units as the cap each time.
5. Smart virtual number：
（1）010 prefix：It takes a hundred thousand numbers as a unit. The first-time application is limited to one unit. The utilization rate should be more than 80% before it can be applied again, with five units as the cap each time.

（5）080 prefix：It takes ten thousand numbers as a unit. The first-time application is limited to three units. The utilization rate should be more than 80% before it can be applied again, with one unit as the cap each time.
（6）099 prefix：It takes ten thousand numbers as a unit. Each application is limited to ten units. The utilization rate should be more than 80% before it can be applied again.
6. IoT number：It takes a hundred thousand numbers as a unit. For the first-time application, fifty units are the cap. The utilization rate should be more than 70% before it can be applied again, with twenty-five units as the cap each time.

After the telecommunications enterprise allocated with subscriber numbers by the competent authority, it should stipulate the number selection principle of the golden numbers except for the IoT numbers, and report it to the competent authority for reference before implementation; the same should apply to revisions hereof.
The number selection principle prescribed in the preceding paragraph should include the basic number selection principle（as shown in the attached tables）; the subscriber numbers included in the number selection principle by the telecommunications enterprise should be provided to subscribers for lease through auction or number selection with a fee.

2. If the telecommunications enterprise does not reach the minimum utilization rate of the subscriber numbers set by the competent authority, unless the first-time allocated subscriber numbers have been allocated for less than three years or the re-allocated subscriber numbers have been allocated for less than one year.
