Migration Access Codes - also known as MAC codes, MAC keys or even MAC numbers - allow you to switch broadband provider without any break in your service.

How to get a MAC code

To get your MAC Code, first call your current internet provider on their customer service number. Then call your new internet provider, or visit their website, to switch online. The following table pulls together all the information you need. But before you switch, why not compare broadband deals in your area with our Ofcom-accredited service?

What is a MAC code?

Migration Access Codes, generally known as MAC codes allow you to seamlessly switch broadband provider, without any break in your service. Technically, a MAC code is like a serial number used to identify your broadband connection within the local exchange. If you’re switching provider and they have this code, they can simply move your connection over to their service.

What does this mean? - This means that rather than going without the internet for three to four weeks while you wait for your new connection, your switchover will be seamless – with little or no downtime, no need for an engineer to visit and you could even save on connection fees.

How do I get one? - The handing out of MAC codes used to be discretionary, but telecoms regulator Ofcom decided this was unfair. It has since introduced new legislation so all ADSL internet service providers must now provide customers with a MAC code when requested.

Restrictions - If you have a local loop unbundled (LLU) connection, for TalkTalk, Plusnet and others, or a cable connection, e.g. Virgin Media, you won’t be able to use the MAC migration service to switch provider.

However some internet service providers are trialling LLU MAC codes. Instead you’ll have a break in your broadband service until your new connection is up-and-running.
