Glossary: Mac code

Stands for either Migration Authorisation Code or Migration Access Code and is a 17-19 digit alphanumeric code used when switching broadband providers and allows broadband customers to switch between providers with minimal, if any, disruption to broadband service. A MAC code is like a serial number used to identify your broadband connection within the local exchange. If you’re switching provider and it has this code, it can simply move your connection over to its service. Customers apply to their current provider that will issue the unique MAC code, which is then given to the new provider, but it’s very likely the new provider will do this on the customer’s behalf.
