Calling Number Display (CND) allows the people you call to see your telephone number displayed on the screen of their telephone. It applies to both mobile phones and landlines. If you don't have a silent line, unlisted number or have not blocked CND, the people you call will generally be able to see your number on their telephone screen.

The CND feature has important privacy implications because there may be times when consumers don't want their number identified to the person they are calling. Recently, the Calling Number Display Guideline was reviewed by the Communications Alliance.

In our submission ACCAN recommended that the Guideline be reconfirmed, and that:

• the guideline includes a requirement for providers to publish information about their billing practices and whether they display silent numbers on phone bills;
  
  
• the guideline includes a requirement for providers to publish information for domestic and family violence support service providers on how to obtain a line that does not appear on billing;
  
  
• the requirement for service providers to inform their customers that CND cannot be blocked when calling emergency services is retained;
  
  
• the requirement for service providers to advise consumers as to the availability (or lack therefore) of CND on their networks is retained;
  
  
• the requirement to inform consumers that they are free from contractual obligations if a technological change means that CND blocking or enabling is no longer available on the provider’s network is retained.
