Three PAC Code
How to get your Three PAC code, keep your number, and switch networks.
Do NOT cancel your contract manually
If you cancel your contract before transferring your number, your number will be permanently disconnected and you will lose it. The switching process automatically cancels your old contract once your number has moved.
How to Get Your Three PAC Code
The quickest way to get your Three PAC code is to text PAC to 65075 from your Three phone. You'll receive your PAC code by text within a minute.
You can also get your PAC code by:
- Calling 333 from your Three phone (or 0333 338 1001 from another phone)
- Logging into your account at three.co.uk/support/switching
Your PAC code is valid for 30 days. If it expires, simply request a new one.

How to Switch to Three
To switch to Three and keep your current number:

- Choose a Three plan and sign up
- Give Three your PAC code during or after sign-up

Three STAC Code
If you want to leave Three but don't want to keep your phone number, text STAC to 75075. This gives you a STAC code (Service Termination Authorisation Code) that cancels your contract without porting your number.
Which Network Does Three Use?
Three is one of the UK's four major network operators (MNOs). It owns and operates its own mobile infrastructure including masts, transmitters, and core network equipment.
Several virtual networks (MVNOs) use Three's infrastructure: iD Mobile, SMARTY and Honest Mobile. These networks share Three's coverage but set their own prices and plans.
