What do I need to transfer my number?

  • An active giffgaff SIM
  • PAC (Porting Authorisation Code) from your current mobile network

How do I request a PAC code?
Just contact your current provider and ask them for it, saying you want to transfer your number to another network. They have to give you the number immediately, so the sprocess won't take too long.

What is the number transfer process?
Once you’ve completed the number transfer form, a few things will start to happen.

  • Both SIMs will stop working, though not necessarily at the same time
  • After a while (it could be 10 minutes or a few hours), your giffgaff SIM will spring back into action with your number now transferred
  • Calls, texts and data will start working during the day, though not all at the same time.

Important note: On the day of transfer you'll experience a loss of service during the transfer process. You may not be able to use either your old number or your giffgaff number for several hours up to 9pm on the day the number is transferring. Turn your phone on and off throughout the day.
