How to get a giffgaff PAC code
| You want to | Do this | From giffgaff’s own help page |
|---|---|---|
| Keep your number | Text PAC to 65075 | Free. giffgaff says the code arrives within 60 seconds |
| Leave without your number | Text STAC to 75075 | Free |
| Do it another way | Your profile and settings page, or call 43431 | Both listed by giffgaff for PAC and STAC |
You need to be in the UK to ask for a PAC, giffgaff says. You can still ask for one for up to 30 days after leaving, and it is valid for 30 days from issue. Verified
Credit is lost when you port out. giffgaff says remaining credit and unused plan days are not refunded after a port-out, so time the switch near the end of your plan. Verified

We don't yet know how giffgaff's phone menu is structured, so we're not going to guess. If you work it out, we'd like to hear from you.
Before you call
What to know first
There is no giffgaff customer service phone line to call. Its help centre sends you to the giffgaff HelpBot, an AI chat that passes you to an agent if it cannot help. The one number it gives, 43431, is for PAC and STAC requests. Verified
Rolling plans: turn off auto-renew. giffgaff says you can cancel a monthly rolling plan at any time, and your allowance lasts until the current plan expires. Every plan lasts one month. Verified
18-month contracts: end it in your account or the app. Online, giffgaff gives Orders & payments, then Terminate your contract, then End my contract. In the app: Account, Payments methods, Leaving giffgaff, Close my account. Verified
Fourteen days to change your mind from activation. giffgaff counts the 14 days from the moment you activate your SIM. Verified
The codes
How to actually leave
Keep your numberText PAC to 65075
A PAC ports your number to the new provider. Give it to them, not to giffgaff.
Start freshText STAC to 75075
A STAC closes the account without taking your number with you.
giffgaff lists three routes for each code: the text, your profile and settings page, or a call to 43431. You must be in the UK to request a PAC. If your SIM was deactivated after six months without use, giffgaff says its agents can still issue a PAC within 30 days of deactivation. Verified
What it costs
Notice, exit fees and the handset
NoticeNone stated
giffgaff states no notice period. Rolling plans stop when you turn off auto-renew, at the end of the current month; contracts end through your account.
Leaving early18-month contracts: half the plan price for each full month left.
giffgaff’s own formula: the cost of your current or most recent plan, divided by two, multiplied by the number of full months left. It publishes no worked example. The formula is for its 18-month contracts; giffgaff says monthly rolling plans can be cancelled at any time.
Your handsetA giffgaff phone loan is a Klarna loan, and you keep paying it.
giffgaff says its phone loans come from Klarna, and that you are responsible for all payments until the loan is complete. It does not say in plain terms what happens to the loan when you leave, so check your Klarna agreement before you switch.
Your rights
What you're entitled to
- Your code has to arrive within a minute. For residential customers Ofcom requires the losing provider to send a PAC or STAC no later than one minute after the request. Beware of guides quoting two hours or two working days; those are the rules for business customers. Verified
- Text is not the only route they must offer. Providers must give at least three free ways to get a code: by text, online through your account, and by phone. Text and online have to be available at all times. Codes last 30 days. Verified
- Switching kills the notice period. If you move using a code, your old contract terminates on the working day the switch completes, and your provider must not bill you for any notice period running past that date. This is the single most valuable rule here. It does not, however, cancel an early termination charge if you are still inside your minimum term. Verified
- They must tell you what you still owe on the handset. The switching information sent with your code must say whether the handset sits on a separate contract, and either what is still payable on it after you move or the date you stop paying. It must also give your total final charge as a single figure. Verified
- The switch itself is quick, and free. Porting must complete within one working day, any loss of service must not exceed one working day, and no charge may be made for taking your number with you. Your number stays portable for at least a month after you leave. Verified
One rule is worth more than any script: switch with a code and your provider cannot bill you for a notice period beyond the switch date. The full explainer, including what it does not cover, is here.
