Porting Authorisation Code

Porting Authorisation Code (PAC) is a unique identifier (normally 9 characters long and in the format "ABC123456") used by some mobile network operators to facilitate mobile number portability (MNP). This allows users to retain their mobile telephone number when switching operators.

United Kingdom

Telecommunications service is regulated in the UK by Ofcom. On 25 July 2003, Ofcom introduced the General Conditions of Entitlement which apply to all communications networks and service providers in the UK.

Condition 18 requires all providers to provide number portability but only to subscribers of publicly available telephone services who request it. Number portability must be provided as soon as practicable and on reasonable terms to subscribers and bilateral porting arrangements between providers must accord with agreed processes.

  1. A current Service Provider must give a customer a Porting Authorisation Code (PAC) or a reason why it cannot be issued within 2 working days of their request.
  2. A PAC is valid for a period of 30 calendar days and the customer's request must be submitted to their new Service Provider within that time.
  3. A number can then be transferred anytime between 2 and 32 calendar days from the date the PAC is issued.

If the customer is on a fixed term contract, they will often be expected to pay any outstanding sums owed to the end of the contract before they can port their number. Some mobile phone companies can charge a fee to move the customer's number. This is usually no more than £25. The provider must issue a PAC within 2 hours of the request even if the customer has not paid their bill.

India

In India, the rules for Number portability are prescribed by the Telecom Regulatory Authority of India.

  1. You are allowed to move to another mobile service provider only after 90 days of the date of activation of your mobile connection or from the date of last porting of your mobile number, which ever is applicable.
  2. You are allowed to change mobile service provider within the same service area only.
  3. If you are a postpaid subscriber, please ensure that you have paid all the dues as per your last bill (You will have to sign an undertaking in the Porting Form also).
  4. If you are a Pre-paid subscriber, please note that the balance amount of talk time, if any, at the time of porting will lapse.
