Switch from Tesco Mobile to Three and keep your number using a PAC code
Ofcom’s policies have made it extremely quick and easy to switch and transfer your Tesco Mobile number to Three.
It’s completely free to transfer your number - you simply need to request a PAC code from Tesco Mobile by sending a text message, which takes no more than 2 minutes to arrive. Once you’ve handed the PAC code to Three, the switching process will take no more than 1 to 2 working days to complete.
If you want to join Three and get a brand new phone number, without keeping your existing Tesco Mobile number, the process is almost identical - the only difference being you will need to request a STAC code instead of a PAC code.
Joining Three from Tesco Mobile
Joining Three and transferring your number from Tesco Mobile is a very easy process, and should take no more than 1 to 2 working days.
You simply need to request a free PAC code from your Tesco Mobile number, and hand it to Three.
You can hand your PAC code to Three at the time of ordering a new Three phone or Three SIM, or you can do this after you’ve received your order. When you choose to do this is up to you - it doesn’t make a difference.
After you’ve handed your PAC code to Three, your number will be transferred to Three within 1 to 2 working days, and your account with Tesco Mobile will automatically be closed.
1. Request a PAC code from Tesco Mobile
Requesting a PAC code from Tesco Mobile is quick and free. The easiest way to do this is via text:
- Text: From your Tesco Mobile number, text PAC to 65075 for free. You will receive a reply within 2 minutes, containing your PAC code
- Online: Contact Tesco Mobile via the online live chat service and request a PAC code
- Phone: Call 4455 from your Tesco Mobile number or 0345 301 4455 from any other number
- Store: Find your nearest Tesco Mobile store and ask to leave
You will have 30 days to hand your PAC code to Three, after which it will expire and you will need to request another one from Tesco Mobile.
Note: If you wish to switch to Three, but you want a brand new number without keeping your Tesco Mobile number, you need to request a STAC code rather than a PAC code from Tesco Mobile. You can do this by texting STAC to 75075 instead.
2. Order a new phone or SIM from Three

You may have the opportunity to hand your PAC code over at the time of ordering a new phone or SIM from Three. If so, you will have the option to enter your PAC code during the checkout process. Once your order arrives and you activate the SIM, the transfer process will automatically begin.
If you’re not given the opportunity to hand your PAC code to Three at the time of ordering, don’t worry. Instead, you will receive a temporary number with your new Three SIM. You will be given the opportunity to hand your PAC code to Three and transfer your Tesco Mobile number once your order arrives, as detailed in the next step.
Note: Apart from being slightly more convenient, it doesn’t make a difference whether you choose to hand your PAC code to Three at the order checkout or after you’ve received your order.
