STAC is short for Service Termination Authorisation Code.
Not everyone wants to keep their old number when switching networks. A STAC lets you switch over to Three and get a brand new number from us.
To keep your current number when you switch to Three, you’ll need a PAC (Port Authorisation Code).
To leave your number with your old provider, you’ll need a STAC (Service Termination Code).
Find out more about switching to Three, get help with the switching process and see useful FAQs.
