NPAC Service
In November 2004, TTC was designated by 12 of the Type 1 Telecom operators to construct and operate Number Portability Administration Center (NPAC). Starting on October 13, 2005, under the supervision of the competent authority, TTC began assisting telecom operators with Taiwan's official Number Portability Service (NP Service). The service has been continuously operated by TTC for over two decades. As of the end of August 2025, number portability services have been successfully completed for more than 60,000 landline numbers and about 83.33 million mobile phone numbers.
In order to enhance information security, TTC has introduced the ISO 27001 information security management system for NPAC operation. And the regular re-inspection and auditing are made by British Standards Institution (BSI) as the third-party certification body to ensure the NAPC operation meets the ISMS standards.
