Switching from O2 to Orange? It's a straightforward process to keep your existing phone number.

Step 1: Get a PAC Code from O2

If you’d like to move your phone number from O2 to Orange, the first step is getting your Porting Authorisation Code (or PAC Code) from O2.

There are three ways to get a PAC Code from O2:

  1. Online: You can get a PAC Code from O2 by logging in to the My O2 website. Once you've logged in, go to My details > Thinking of switching from O2?.
  2. By Text Message: You can get an O2 PAC Code sent to you via SMS text message. Text PAC to 65075 to receive a PAC Code from O2.
  3. By Phone: You can get a PAC Code by calling O2. To do this, call them on:
    • For O2 Pay Monthly, dial 202 (or 0344 8090202 from any other phone)
    • For O2 Pay As You Go, dial 4445 (or 0344 8090222 from any other phone)
    You'll need to call during O2's opening hours (Monday-Friday 8am-9pm, Saturday 8am-8pm, Sunday 8am-6pm).

Here are some key things to know:

  • The PAC Code from O2 should consist of six numbers with TEL at the start (e.g. TEL 123 456).
  • Your PAC Code is valid for 30 days. If you don't use it during this time, the PAC Code will expire and you'll need to request a new one.
  • You shouldn't close your account at O2: it'll be closed automatically when your phone number is transferred to Orange.

Still in contract with O2? If so, you may need to pay an early exit fee on your bill from O2. To find out how much this would be, text INFO to 87075.

Don’t want to keep your O2 phone number? You can switch to Orange without taking your phone number with you. If you'd like to do this, get a STAC Code from O2 instead.

O2 STAC Code (Leave O2 Without Keeping Your Number)

If you’d like to leave O2 without keeping your phone number, you’ll need to request a STAC Code rather than a PAC Code. There are three ways to get a STAC Code from O2:

  1. Online: You can get a STAC Code from O2 by logging in to the My O2 website. After logging in, go to My details > Thinking of switching from O2?.
  2. By Text Message: You can get an O2 STAC Code sent to you via SMS text message. Text STAC to 75075 to receive a STAC Code from O2.
  3. By Phone: You can get a STAC Code by calling O2. Call them on:
    • For O2 Pay Monthly, dial 202 (or 0344 8090202 from any other phone)
    • For O2 Pay As You Go, dial 4445 (or 0344 8090222 from any other phone)
    You'll need to call during O2's opening hours (Monday-Friday 8am-9pm, Saturday 8am-8pm, Sunday 8am-6pm).

Once you’ve gotten your STAC Code from O2, the rest of the process for joining Orange remains the same.

Step 2: Order your new phone or SIM card from Orange's website

You should now order your new phone or SIM card using the Orange website. Please select the type of tariff you're intending to move to:

For a full list of available tariffs and the latest Orange deals, please refer to this page on Orange's website.

Orange will assign you with a temporary phone number during the transition process. This will allow you to test out the service before you finally transfer your phone number to Orange.

Step 3: Give the PAC Code to Orange

Once your new phone or SIM card arrives from Orange, switch it on and make sure everything's working properly. If, for whatever reason, you need to return or change the handset or SIM card, it's best to do this before transferring your phone number.

Once you're happy to continue with the phone number transfer, contact Orange and provide them with your PAC Code from O2.

Your PAC Code should be entered on Orange's online form. You can also provide your PAC Code to Orange over the phone:

If you're joining Orange Pay Monthly, you can submit your PAC Code by calling 150 on your Orange handset. Alternatively, call 07973 100 150 from any other phone.

Alternatively, if you're joining Orange Pay As You Go, submit your PAC Code by calling 450 (07973 100 450 if you're calling from another network).

If you have a STAC Code from O2 rather than a PAC Code, this can be provided to Orange in the exact same way.

Providing your PAC Code to Orange
The PAC Code should be submitted through a form on Orange's website.

Remember:

  • You must provide the PAC Code to Orange within 30 days of it being issued by O2. If the PAC Code has already expired, you'll need to return to step 1 and request a new PAC Code from O2.
  • O2 Pay As You Go customers: Try to use up your remaining credit as it can't be transferred to Orange.

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to Orange before 5.30pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). After 5.30pm, you'll need to wait one extra working day for your number to be transferred.

On the day of the transfer, you'll momentarily lose coverage on both mobile networks. When this happens, restart your handset on Orange. You should find that the Orange phone or SIM card will now associated with your original phone number.

  • If you see an error message (e.g. "SIM card registration failed"), this means it's time to restart your phone.
  • Once the phone number has been transferred to Orange, your account on O2 will automatically be closed. You'll receive a final bill from O2 for any outstanding charges.

  • I am switching from O2 to Orange. My new phone arrived last Thursday. I contacted O2 and was given a PAC more or less immediately. First thing Friday morning, the new phone had been activiated so I rang Orange (150) and gave them the PAC to get my old number transferred. I was told that my number should transfer between 10am and 3pm the following day….I’m still waiting, it’s now Tuesday pm and nothing has happened. I did think well maybe he hadn’t realised that the following day was saturday and these things didn’t happen on a weekend. But surely something should have happened by now! I know your advice will be ring Orange, but an hours wait on the phone, while I’m at work isn’t ideal!

    • Hi Lou,

      Thanks for getting in touch. You’re right in saying that phone numbers don’t transfer at the weekend, so a request submitted on Friday morning should go through on Monday (Tuesday if you miss the cut-off time). As your number still hasn’t transferred as of Tuesday evening then it seems like Orange have failed to transfer your number correctly. I’m afraid my advice would indeed be to contact Orange… though fingers crossed the wait shouldn’t be as long as an hour. Orange are the most likely people to know what’s happened: i.e. whether your request was correctly entered into the system, the status of your number port, etc.

    Hi Ken,

    I used my PAC code yesterday to transfer my number from O2 to Orange. It is now just over 24 hours later. When I call from my new phone, the number shows up as the transferred number as expected. However when I call to the trasferred number from another phone, the call still goes to my old phone with my old O2 sim. Is this normal? Will it be resolved if I wait a few more hours?

    Thanks.

    • Hi Paul,

      I believe this problem may occur temporarily – your old network (O2) still needs to release the number to Orange. On the Orange side, they’ve changed the “Caller ID” number to the number you’re transferring from O2. If this problem isn’t resolved after a few hours, I’d recommend getting in touch with O2. Let me know how it goes!

  • I had a pack code from O2.. Purchased a new phone from Orange //phoned to give them the Pac code. it has been a week of constant phonecalls saying within 24 -48 hours it willbe sorted. I have no service apparently my temporary number has not been activated. SO a weel later and still no joy. How long should it take is it better to forget the pac code and ask for a new sim and start again
