What is a Post Office MAC code?
Post Office MAC codes, or migration authorisation codes, allow you to change from your existing broaband supplier, Post Office, to another broadband supplier (internet service provider or ISP) without losing broadband connectivity (or at the very worst, losing your connection for a couple of hours).
If you are thinking of switching your internet service provider from Post Office, then you should use our handy tool above which will provide you with all the information you require to obtain your MAC code and switch internet service providers. The process is termed broadband migration. It's quick, free and very easy to do - follow the instructions above for full details on how to obtain your Post Office MAC code.
By switching internet service providers, you could potentially save hundreds of pounds a year... New broadband deals are available all the time and prices are getting cheaper with increased competition (just look at how many internet service providers we have listed on the left side of this page!), so if you have been with Post Office for a long time, it is highly likely that there are better broadband deals out there, saving you lots of money!
Post Office Mac codes are free. There is no charge for a MAC code.
Post Office Mac codes consist of four letters, followed by between seven and nine numbers, a slash, and five alphanumeric characters (e.g. LAEM3456789/1F14T).
