The ICT Authority is accountable to the National Assembly through the Ministry of Information Technology and Telecommunications.

Parliament passed the Information and Communication Technologies Authority Act in late 2001, effectively creating the ICT Authority which has the status of a body corporate.

Operators who want to start or conduct telecom operations must apply to the ICT Authority for a licence. The ICT Authority is also in charge of the Mauritian numbering plan and allocates number resources to telecom operators.

With the radio frequency being a limited natural resource, frequencies must be allocated fairly among those who apply. The authority is also empowered to investigate cases of radio interference.

The ICT Authority has, among other functions, to act as the Controller of Certification Authorities (CCA). The Controller of Certifying Authorities as the “Root” Authority certifies the technologies, infrastructure and practices of all the Certifying Authorities licensed to issue Digital Signature Certificates

It is also responsible for protecting consumers of telecommunication services.
