Condition 18 of OfCom's 'General Conditions of Entitlement' (which apply to all communications networks and service providers in the UK) provides for the following:
Quote:
- Your current Service Provider must give you a Porting Authorisation Code (PAC) or a reason why it cannot be issued within 2 working days of your request. You can obtain your PAC by calling the customer service group of your current network. Usually your network operator will be able to provide your PAC over the phone and will then follow this up in writing.
- Your PAC is valid for a period of 30 calendar days and your request must be submitted to your new Service Provider within that time.
- Your number can then be transferred anytime between 2 and 32 calendar days from the date your PAC is issued.
