Keep your number when you join giffgaff
To transfer your phone number to giffgaff, you first need to ask your old mobile provider for a Porting Authorisation Code (PAC). You can then use the transfer form to submit your PAC and choose a date for the transfer. If your number hasn't been transferred the day after the scheduled date, you can contact an agent about it. We can only transfer UK numbers to giffgaff.
Transfer your number to a new SIM
When you change your SIM card to a different SIM (e.g. to change to a nano SIM) you can transfer your number and existing credit and goodybag by performing a SIM swap.
Phone number deactivation
SIMs are deactivated if they aren’t used for 6 months. If you want to stop this, make sure you use your phone from time to time.

For issues with porting out, payment will be made back to your saved card. For issues with porting in, we will apply credit to your account.
