C566:2023 (pdf 508kb)

The Code sets out arrangements relating to:
(a) CSPs either Holding, or wanting to Hold, Numbers for use by them in connection with the supply of a Listed Carriage Service to a Customer; and
(b) Carriers in their role of supplying Listed Carriage Services using Numbers.

The Code objectives also include clarifying a CSPs obligations in providing Rights of Use (ROU) when a Number is Issued; and enables ROU Holders to understand how they can use a Number Issued to them and what is and is not permitted.

The 2023 version of the Code replaces both the :
• C566:2005 Rights of Use of Numbers Industry Code and
• C554:2004 Rights of Use of Premium Rate Service Numbers Industry Code.
