Note: we have an updated guide on getting your PAC in the How-to Guides section, please see here. 
If you want to contact O2 about leaving or getting a PAC, you can also use the Social links below:
Seen this a lot around the forum, so I thought I'd make a post on how to do it
Firstly, give O2 Customer Service a call on 4445 fron your O2 Mobile.
Select the option which is "Join or leave O2". Then in the next menu select the option "To leave O2".
Now, you will be put through to an advisor who will ask you for your name and phone number. Then ask them for your Port Authorisation Code. You will be asked for your security password if you have set one up with them. Don't worry if you havn't sent one up; if you don't have one then you will not need to give it to them.
You will be asked if you have a pen and paper ready to write the code down. Don't worry if you haven't because they post it out to you anyway. They will ask you for your name and address so they can post it to you.
O2 may ask for a reason for leaving and the Port Authorisation Code (PAC) is only valid from 30 days of issue. Provide your PAC code to another operator if you wish to keep your existing number from another network.

Thanks. I suppose I must try them and see which one works!
Probably best that you have them all to hand @Anonymous the way O2 have been leaving phones unanswered recently...

Like I said there isn't a specific one that will get you straight through, you still have to navigate the options.
