Migration Authorisation Code

In the UK a Migration Authorisation Code (MAC) is a unique identifier used by broadband consumers when they wish to switch broadband service provider. The code was introduced by Ofcom and BT as a voluntary code of practice and is now standard practice for service providers.

Currently (Jan 2006) the only reasons why a losing dervice provider (LSP) may refuse to issue a MAC are that:

• The customer has failed standard checks to validate that he is the account holder
• The broadband service contract has been terminated
• The LSP has already submitted a cease request to BTW for the broadband service
• The account holder is deceased

Definition of Terms

• SP - Service Provider
• GSP - Gaining Service Provider
• LSP - Losing Service Provider

• MAC - Migration Authorisation Code
• Customer - The user of the broadband connection
• Account holder - The person or entity with contractual responsibility for the broadband service
• Migration - Transfer of a broadband customer between SPs, where both SPs provide service over the same BT copper loop
