Want to keep or change your number when switching to iD Mobile? You’ll need a PAC or STAC from your previous network. Watch our quick video guide to get started, or follow the detailed steps below:
Please note: If you’ve already submitted your PAC or STAC when you purchased your plan, there's no need to resubmit your request. Your switch will take place on the date you specified.
What is a PAC and STAC?
- A PAC (Porting Authorisation Code) is a unique 9-digit code that lets you transfer your number to a new network.
- A STAC (Service Termination Authorisation Code) is a unique 9-digit code that cancels your old number when switching to a new network.
How do I request a PAC or STAC?
In most cases, you can request a PAC or STAC from your old network via text, free of charge. Using your old SIM, text PAC to 65075 or STAC to 75075. Your PAC or STAC will be sent immediately and is valid for 30 days.
If you have more than one mobile number on your account, you’ll need to contact your old network directly.
What do I do once I’ve received my PAC or STAC?
Got your PAC or STAC? Great! Click here to start your switch. You’ll also need your 9-digit transaction number. This can be found in your ‘Thank you for your recent purchase’ email, your ‘Order Complete’ email, or on your paper invoice. It can also be found at the bottom of your ‘Welcome to iD’ email.
Please note: Your Transaction Number starts with 4.
