Switch from Vodafone to Giffgaff and keep your number using a PAC code

Joining Giffgaff and leaving Vodafone

Joining Giffgaff and transferring your number from Vodafone is a simple process and usually takes no longer than 1-2 working days.

The process which will go through in more detail below involves requesting a PAC code from Vodafone and handing it to Giffgaff.

You can either hand the PAC code over to Giffgaff during the ordering process or after you have received your new SIM card or eSIM has been activated.

1. Request a PAC code from Vodafone

Switching from Vodafone and keeping your current phone number is really simple. There is no need to memorise a new number or update your contacts!

Here is how to get your PAC (Porting Authorisation Code) from Vodafone:

• Text: Text "PAC" to 65075 from your Vodafone phone. You'll receive a text with your code within 2 minutes. This is a free service provided by Ofcom (the UK's communications regulator).
• Online: Contact Vodafone through their website's live chat service and request a PAC code.
• Phone: Call Vodafone's customer service on 08080 408 408 and ask for a PAC code.
• In-store: Pop into your nearest Vodafone store and request a PAC code in store. 

Your PAC code is valid for 30 days, so you can request it before you get your new SIM card.

If you want a new number and do not wish to keep your current number, you will need to request an STAC code instead of a PAC code. Text "STAC" to 75075 to get your STAC code.

During the ordering process you may be given the opportunity to share your PAC code from Vodafone to Giffgaff, if you choose this option then the number transfer process will start once your new sim card arrives and you activate it in by putting it in your phone and turning it on, this also means you can skip to step 4 of this article if you wish!

If you are not given the opportunity to hand over your PAC code when ordering then there's no need to panic. Once your new sim card from Giffgaff has arrived, just continue to step 3 of this article.

It is also worth calling out that it doesn't matter if you are able to hand over your PAC code from Vodafone whilst buying your new sim from Giffgaff or not it's just slightly more convenient but the outcome is the same!

Does Giffgaff require a credit check?

No, Giffgaff offers SIM only plans without a credit check. If avoiding a credit check is important to you, that makes switching to Giffgaff more straightforward.

Does Giffgaff support eSIM?

Yes, Giffgaff supports eSIM. That means you may be able to switch without waiting for a physical SIM card, depending on the plan and activation process you choose.

3. Give the PAC code to Giffgaff

Once you have your PAC code, follow these steps to give it to Giffgaff:

• Activate your Giffgaff SIM card: If you have not already, activate your Giffgaff SIM card.
• Find the number transfer link: After activating your SIM, Giffgaff will provide you with a link to transfer your number.
• Enter your PAC code: Follow the link and enter your PAC code when prompted.

Giffgaff will then handle the transfer of your number.

Important Notes:

• If you want a new Giffgaff number and don't need to keep your current number, request a STAC code instead of a PAC code from your current network.
• If you don't use your PAC code within 30 days, you will need to request a new one.
• If you can't find your Giffgaff activation code, you can activate your SIM using the serial number (found on the back of the SIM card).

4. Wait for your number transfer to Giffgaff to complete

That's it you've done the hard work, now sit back and relax. Giffgaff will notify Vodafone of your intention to leave and take your mobile number to Giffgaff.

The number transfer process will usually take 1 to 2 working days. After this time your Vodafone mobile number will be working on the Giffgaff SIM card.
