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

EE

Step 1: Get a PAC Code from Three

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

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

  1. Online: You can get a PAC Code from Three by logging in to the My3 Account website.
  2. By Text Message: You can get a Three PAC Code sent to you via SMS text message. Text PAC followed by your date of birth in DDMMYY format to 65075 to receive a PAC Code from Three.
  3. By Phone: You can get a PAC Code by calling Three. To do this, call them on 333 using your Three handset. Alternatively, dial 0333 338 1001 from any other phone. You'll need to call during Three's opening hours (Monday-Friday 8am-8pm, Saturday 9am-6pm, Sunday 9am-6pm).

Here are some key things to know:

  • The PAC Code from Three should consist of six numbers with HTG at the start (e.g. HTG 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 Three: it'll be closed automatically when your phone number is transferred to EE.

Still in contract with Three? If so, you may need to pay an early exit fee on your bill from Three. To find out how much this would be, text INFO followed by your date of birth in DDMMYY format to 87075.

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

Three STAC Code (Leave Three Without Keeping Your Number)

If you’d like to leave Three 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 Three:

  1. Online: You can get a STAC Code from Three by logging in to the My3 Account website.
  2. By Text Message: You can get a Three STAC Code sent to you via SMS text message. Text STAC followed by your date of birth in DDMMYY format to 75075 to receive a STAC Code from Three.
  3. By Phone: You can get a STAC Code by calling Three. Call them on 333 using your Three handset. Alternatively, dial 0333 338 1001 from any other phone. You'll need to call during Three's opening hours (Monday-Friday 8am-8pm, Saturday 9am-6pm, Sunday 9am-6pm).

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

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

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

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

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

EE 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 EE.

Step 3: Give the PAC Code to EE

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

Your PAC Code should be entered on EE's online form. Alternatively, you can give the PAC Code to EE by calling 150 on your EE handset. You can also call 07953 966 250 from any other phone.

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

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

Remember:

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

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to EE 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 EE. You should find that the EE 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 EE, your account on Three will automatically be closed. You'll receive a final bill from Three for any outstanding charges.

    Hi,

    I’ve got my PAC code from three, but when I go through the transfer number over form on EE it says it’s wrong. I’ve quadruple checked it, and I know it’s right. I don’t understand why this would happen.

    • Hi Georgina,
      I believe your PAC Code from Three should start with HTG and be followed by six numbers (e.g. HTG 123 456). Is the PAC Code you have from Three in this format? If so, I’d consider getting in touch with EE Customer Services on 150 to let them know and to see if they’re able to accept this PAC Code for you.

    Hi I have moved from 3 to ee and transferred my number. Got PAC code from 3 gave it to ee. EE have transferred my number and sent me a text to say it is completed but the number is still live on 3. I can now use the same number on both networks. What has gone wrong ?

    • Hi Keith,
      Many thanks for your comment: this is a rather odd situation. What happens when you call through to the phone number (ideally, testing this from a different mobile network like O2 or Vodafone)? Does it connect to Three or EE? This shouldn’t normally happen, but usually it’s the responsibility of your new mobile network (so EE) to resolve problems with the port.

  • I am preparing to switch from Three to EE due to repeated network failure. If I obtain a PAC code from Three can I then cancel payments once the code has been given to EE or will this result in my loosing my existing number due to inactivity.

    I should explain that my 24 monthly contract expired in October.

    • Hi Derek,
      Many thanks for your comment. There’s actually no need to separately cancel your contract with Three: it’ll be done for you automatically when your phone number moves to EE. It’s likely that a 30-day notice period applies on your Three SIM card, so they may charge you for up to another 30 days after you move your phone number over.
