Register of telco industry codes and standards

We maintain a register of telecommunications industry codes and standards.


About the register

Telecommunications companies must follow the rules in the Telecommunications Act 1997 (the Act). The codes and standards contain these rules.

The register we maintain must include all:

  • Industry codes that have to be registered under Part 6 of the Act
  • Industry standards

After we register a new code or standard, the Communications Alliance publishes it and we add it to this list.
