Changed your mind?

If you’ve changed your mind about transferring your number, get in touch with us and we’ll be happy to help.

Give us a call

If you'd like to chat, give us a call on 202, free from your O2 phone, or 0344 809 0202 from a non-O2 phone.

Are you a VIP customer?

If you're a VIP customer, you will need to call your dedicated Customer Service team to discuss keeping your number. Please find more information below.

If you're switching to O2 from another network and want to keep your mobile number, you'll need to ask your old network for a PAC (Porting Authorisation Code).

You can get your PAC by texting PAC to 65075. You'll get it in 60 seconds. Alternatively, you can contact your current provider.

How do I use my PAC code?
You can give us your PAC code when you order your new O2 connection or at any time afterwards. To do this, please contact your VIP personal Customer Service team.


We’re sorry you’re thinking of switching. We’re here if you’d like to discuss your options or hear about any offers – just give your VIP personal Customer Service team a call.

How do I check if there’s anything to pay on my account?
Please contact your VIP personal Customer Service team if you'd like to know whether there'd be anything to pay if you switched. Depending on what type of plan you're on, you may incur early termination charges.

Find out more about whether this would affect your contract at Leaving O2.

How do I get a PAC or STAC code?
If you decide to switch to another network, you’ll need to request a PAC code if you want to keep your phone number or a STAC code (Service Termination Authorisation Code) if you’d like a new number.

You can request your code by calling your VIP personal Customer Service team, signing in to My O2, or:

  • Texting PAC to 65075 for free, if you want to keep your phone number
  • Texting STAC to 75075 for free, if you don’t want to keep your phone number.


You should receive your PAC or STAC code within 60 seconds.

If you have multiple numbers on your account you won’t be able to use the text service. You’ll need to contact your VIP personal Customer Service team or go to My O2.

If you've already switched or left O2, you can request a PAC code by calling your personal Customer Service team. You have up to 30 days from when you leave O2 to request a PAC code from us, and it will be valid for an additional 30 days from the date of issue.
