Switch from O2 to BT and keep your number using a PAC code

Ofcom’s policies have made it extremely quick and easy to switch and transfer your O2 number to BT.

• Jump straight to instructions

It’s completely free to transfer your number - you simply need to request a PAC code from O2 by sending a text message, which takes no more than 2 minutes to arrive. Once you’ve handed the PAC code to BT, the switching process will take no more than 1 to 2 working days to complete.

If you want to join BT and get a brand new phone number, without keeping your existing O2 number, the process is almost identical - the only difference being you will need to request a STAC code instead of a PAC code.

Joining BT from O2

Joining BT and transferring your number from O2 is a very easy process, and should take no more than 1 to 2 working days.

You simply need to request a free PAC code from your O2 number, and hand it to BT.

You can hand your PAC code to BT at the time of ordering a new BT phone or BT SIM, or you can do this after you’ve received your order. When you choose to do this is up to you - it doesn’t make a difference.

After you’ve handed your PAC code to BT, your number will be transferred to BT within 1 to 2 working days, and your account with O2 will automatically be closed.

1. Request a PAC code from O2

Requesting a PAC code from O2 is quick and free. The easiest way to do this is via text:

1. Text: From your O2 number, text PAC to 65075 for free. You will receive a reply within 2 minutes, containing your PAC code
2. Online: Login to O2, open the My O2 ▾ menu, click Manage your details, then under Thinking of leaving O2? click Request your code. You'll then be asked to perform a quick security check, before you can see your PAC code
3. Phone: Call 202 from your O2 number or 0344 809 0202 from any other number.
   • Monday - Friday: 8am - 9pm
   • Saturday: 8am - 8pm
   • Sunday: 8am - 6pm
4. Store: Locate your nearest O2 store and request to leave O2

You will have 30 days to hand your PAC code to BT, after which it will expire and you will need to request another one from O2.

Note: If you wish to switch to BT, but you want a brand new number without keeping your O2 number, you need to request a STAC code rather than a PAC code from O2. You can do this by texting STAC to 75075 instead.

2. Hand the PAC code to BT

Once you have your PAC code from O2, you simply need to hand it to BT to start the transfer process.

If you previously handed your PAC code to BT at the time of ordering a new BT phone or BT SIM during the checkout process, you can skip this step.

Handing your PAC code to BT can be done through a number of ways:

1. Online: Go to BT keep my number and enter your PAC code
2. Phone: Call 150 from your BT Mobile SIM or 0330 1234 150 from any other number.
   • Monday to Friday: 8am - 9pm
   • Weekends and bank holidays: 8am - 8pm

3. Wait for the switch to BT to complete

After you’ve handed your PAC code to BT, they will notify O2 that you wish to leave them and transfer your number to BT.

It will take 1 to 2 working days for BT to transfer your number. Once the transfer has completed, your account with O2 will automatically be closed.
