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

Step 1: Get a PAC Code from Orange

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

There are two ways to get a PAC Code from Orange:

  1. By Text Message: You can get an Orange PAC Code sent to you via SMS text message. Text PAC to 65075 to receive a PAC Code from Orange.
  2. By Phone: You can get a PAC Code by calling Orange. To do this, call them on:
    • For Orange Pay Monthly, dial 150 (or 07973 100 150 from any other phone)
    • For Orange Pay As You Go, dial 450 (or 07973 100 450 from any other phone)
    You'll need to call during Orange's opening hours (Monday-Friday 8am-8pm, Saturday 8am-6pm, Sunday 8am-6pm).

Here are some key things to know:

  • A PAC Code is 9 digits long and follows the format ABC 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 Orange: it'll be closed automatically when your phone number is transferred to Three.

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

Orange STAC Code (Leave Orange Without Keeping Your Number)

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

  1. By Text Message: You can get an Orange STAC Code sent to you via SMS text message. Text STAC to 75075 to receive a STAC Code from Orange.
  2. By Phone: You can get a STAC Code by calling Orange. Call them on:
    • For Orange Pay Monthly, dial 150 (or 07973 100 150 from any other phone)
    • For Orange Pay As You Go, dial 450 (or 07973 100 450 from any other phone)
    You'll need to call during Orange's opening hours (Monday-Friday 8am-8pm, Saturday 8am-6pm, Sunday 8am-6pm).

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

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

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

Alternatively, if you're getting your Three plan from a reseller, tap on their logo for more information:

Three 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 Three.

Step 3: Give the PAC Code to Three

Once your new phone or SIM card arrives from Three, 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 Three and provide them with your PAC Code from Orange.

Your PAC Code should be entered on Three's online form. Alternatively, you can give the PAC Code to Three by calling 333 on your Three handset. You can also call 0333 338 1001 from any other phone.

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

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

Remember:

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

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to Three before 5pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). After 5pm, 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 Three. You should find that the Three 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 Three, your account on Orange will automatically be closed. You'll receive a final bill from Orange for any outstanding charges.

  • Hi,

    I'm on a 30-day rolling contract with Orange and I would like to switch to Pay as You Go with Three. Is it possible? The point is I have to give a notice of 30 days. What shall I do?

    Thank you,

    Andrea

  • I was with orange network for number of years at least 6 years, last year i decided to move to 3 network as they have a good offer then, Orange has given me my PAC not by request but beacause i was cancelling my contract as i was at the end of it. Orange has sent me my PAC through the post but I decided to have a new number so i did not use my PAC but I was clear that I was cancelling my contract then they even sent me a letter acknowledging that i was leaving and all, but beacause I dont monitor my account, I only realise after a year that they are still charging me. I have spoken to them yet they said they could not do anything about it but to only cancel that contract…..HELP is ther a way to have my money back?
