Three PAC Code: Keep Your Phone Number When Changing Networks
Whether you're joining Three or leaving for a different network, it's a straightforward process to keep your old phone number.
If you're leaving Three and joining another network or if you're leaving another network in order to join Three, it's easy to keep your old phone number. All you need to do is to request a PAC Code: it's totally free and the entire process of transferring your phone number should normally take no longer than one working day.
For detailed instructions, please choose the option that best applies to you:
- I'm leaving Three and joining another network
Transfer your Three phone number onto a different network.
- I'm joining Three from another network
Transfer your phone number onto a new account with Three.
- I'm upgrading my Three phone or SIM card
Transfer your phone number from one Three account to another Three account.
Leaving Three For Another Network
If you're leaving Three and joining another network, you can take your phone number with you.
Start by asking Three to issue you with a PAC Code. You can get a PAC Code from Three by calling 333 on your Three handset. Alternatively, dial 0333 338 1001 from any other phone.
You can request a PAC Code over the phone at any time during Three's opening hours:
|Monday - Friday||8.00am - 8.00pm|
|Saturday||9.00am - 6.00pm|
|Sunday||9.00am - 6.00pm|
It's always free to get a PAC Code from Three (it's your legal entitlement). After getting your Three PAC Code, you'll need to provide it to your new network operator. For detailed instructions, please select your new network operator from the dropdown menu below:

Joining Three From Another Network
If you're joining Three from another network, you should ask your old network to provide you with a PAC Code. The PAC Code will allow you to transfer your number to Three.
After getting the PAC Code, you should order your new handset or SIM card directly from Three's website. For more information, please select the type of tariff you're wanting to move to:

Once Your New Phone Arrives...
Once your new phone or SIM card arrives from Three, turn it on and make sure everything's working properly. If you need to return or change the new handset/SIM card, please do this before you transfer your phone number.
Once you're happy to continue with the transfer, your PAC Code should be entered on Three's online form. Alternatively, you can give the PAC Code to Three by calling 333 on your Three handset. You can also call 0333 338 1001 from any other phone.
If your PAC Code is provided before 5.00pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). For PAC Codes submitted after the 5.00pm cut-off, you'll need to wait one extra working day for your number to be transferred.
Upgrading Your Plan On Three
If you're simply upgrading to a newer handset or tariff, it's not necessary to use a Three PAC Code. You can simply upgrade via Three's website. For more information, please select the type of tariff you're planning to move to:
