giffgaff STAC Code (Leave giffgaff Without Keeping Your Number)

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

When Your New Phone Arrives...
Once your new phone or SIM card arrives from giffgaff, switch it on and make sure everything's working correctly. If, for whatever reason, you need to return or change your handset or SIM card, it's best to do this before transferring your phone number.
Once you're happy to continue with the transfer, your PAC Code should be submitted through giffgaff's online form.
If your PAC Code is provided before 3pm, 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 3pm cut-off, you'll need to wait one extra working day for your number to be transferred.
Sometimes, you’ll be given the option to provide a PAC Code at the same time as when you order your new phone or SIM card. We’d typically recommend against providing your PAC Code at this stage. Instead, waiting for the new phone or SIM card to arrive from giffgaff first will allow you to make sure it’s working correctly and will make the process of cancelling or returning much easier.
