How to switch from giffgaff & transfer your mobile number

Contact giffgaff (after you login) and let them know that you would like to transfer (or 'port-out') your number to another network. A Giff gaff customer support agent will then get back to you with your PAC code. Replies can be found in your giffgaff account message box.

If you wish to use the 'text-to-switch' service, simply SMS text PAC to 65075 free from your giffgaff SIM to get your PAC code by text and begin the porting process.

  • giffgaff will provide your Porting Authorisation Code (PAC) either over the phone, by SMS text message or via email.
  • A PAC code is valid for 30 days. If you don't use it within thirty days it will expire and you will need to request a new one.
  • Your giffgaff account will remain active until your number has been ported over to the new network. After the transfer is complete, your giffgaff account will be automatically closed.

Many of the exclusive mobile phone deals are only available online, directly from the network providers listed here. While you wait for your Port Authorization Code from giffgaff, get the best offer tailored to you.

Finally, provide your PAC code to your new mobile network operator who will then be able to port your existing phone number from giffgaff. They will tell you what day the transfer is due to take place (usually within 48 hours).

Important: Do NOT cancel your contract before switching, otherwise you may lose your existing phone number and be unable to port it over. Once you provide your new network provider with your PAC code, your old account will be clsoed automatically once the number is successfully ported over.

Note: Credit on Pre-Pay / PAYG (Pay-As-You-Go) accounts cannot be transferred over and so any remaining credit balance will be lost after the switch is complete. If you have any credit left, one good option is to donate it to a charity before porting your number.
