Your Giffgaff PAC (Porting Authorisation Code) is the code that moves your Giffgaff number to another network. Under Ofcom's text-to-switch rules, Giffgaff must give it to you instantly and free — no retention calls, no charges on rolling plans.
The fastest way: text PAC to 65075
Text PAC to 65075 from your Giffgaff SIM. You'll get your PAC code back by text within a couple of minutes, along with info on any remaining contract charges. It's free and works on both Giffgaff pay monthly and pay as you go.
All 3 ways to get your Giffgaff PAC code
1. Text PAC to 65075 (fastest)
The universal Ofcom switching service. Send "PAC" to 65075 from the Giffgaff number you want to keep — the code arrives by return text in under a minute. Works for contract and PAYG customers alike.
2. Your giffgaff account online
Log into giffgaff.com → go to your account dashboard → find "Leave giffgaff" / the number-transfer section. Your PAC is generated instantly on screen. There's no phone number to call — giffgaff support is online only (see our Giffgaff contact guide).
3. The giffgaff app
Open the giffgaff app → Account → scroll to the leaving/transfer option. Same instant result as the website.
What happens after you get the code
- Your PAC is valid for 30 days — request a new one if it expires.
- Give it to your new network when activating their SIM. The number transfers within one working day.
- Your Giffgaff account and billing end automatically when the transfer completes — no separate cancellation needed on rolling plans.
- On a fixed-term contract, remaining months may be charged — check the info text that arrives with your PAC.
Leaving Giffgaff? Try the Vodafone network instead
If Giffgaff coverage wasn't right for you, Lebara runs on Vodafone — different masts, different coverage. Plans from around £5/month, no contract, no credit check. Or if Giffgaff's online-only support was the frustration, see our Giffgaff customer service guide — most issues are fixable in minutes.
Giffgaff PAC code problems?
- No text back? Check you sent it from the Giffgaff SIM itself, not another phone. Try 202 if texting fails.
- Code expired? Just text PAC to 65075 again — fresh codes are instant.
- Transfer didn't complete? PACs only process on working days — requests over the weekend complete Monday/Tuesday.
