Leaving TalkTalk For Another Network

If you're leaving TalkTalk Mobile to join another mobile network, you can take your phone number with you using a PAC Code from TalkTalk.

  2. By Text Message: You can get a TalkTalk Mobile PAC Code sent to you via SMS text message. Text PAC to 65075 to receive a PAC Code from TalkTalk.
  3. By Phone: You can get a PAC Code by calling TalkTalk Mobile. To do this, call them on 2883 using your TalkTalk handset. Alternatively, dial 0345 172 0044 from any other phone. You'll need to call during TalkTalk's opening hours (Monday-Friday 8am-8pm, Saturday 8am-8pm, Sunday 8am-8pm).

It's always free to get a PAC Code from TalkTalk Mobile, and it's your legal entitlement to be able to recieve one. If any cancellation fees apply to your TalkTalk Mobile contract, they should also tell you what this will be at the same time as sending you a PAC Code.

TalkTalk STAC Code (Leave TalkTalk Without Keeping Your Number)

  1. Online: You can get a STAC Code from TalkTalk by logging in to the TalkTalk account website. After logging in, go to Switching.
  2. By Text Message: You can get a TalkTalk Mobile STAC Code sent to you via SMS text message. Text STAC to 75075 to receive a STAC Code from TalkTalk.

Once you’ve gotten your STAC Code, the rest of the process for joining your new mobile network remains the same. You can choose your new provider from the dropdown menu above for instructions on how to use your TalkTalk STAC Code.

Joining TalkTalk From Another Network

If you're joining TalkTalk Mobile from a different mobile network, you should ask your old mobile network to provide you with a PAC Code. The PAC Code will allow you to transfer your phone number to TalkTalk Mobile.

After getting a PAC Code from your old network, you should order your new phone or SIM card directly from TalkTalk's website. For more information, please select the type of tariff you're wanting to move to:

When Your New Phone Arrives...

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

Once you're happy to continue with the transfer, You can give the PAC Code to TalkTalk Mobile by calling 2883 on your TalkTalk Mobile handset. You can also call 0345 172 0044 from any other phone.

If your PAC Code is provided before 4pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). For PAC Codes submitted after the 4pm cut-off, you'll need to wait one extra working day for your number to be transferred.

Sometimes, you’ll be given the option to provide a PAC Code at the same time as when you order your new phone or SIM card. We’d typically recommend against providing your PAC Code at this stage. Instead, waiting for the new phone or SIM card to arrive from TalkTalk Mobile first will allow you to make sure it’s working correctly and will make the process of cancelling or returning much easier.

Upgrading Your Plan On TalkTalk

If you're simply upgrading to a newer handset or tariff, it's not necessary to get a TalkTalk Mobile PAC Code. You can simply upgrade via TalkTalk Mobile's website. For more information, please select the type of TalkTalk price plan you're planning to move to:

    I have two sim only i phone 4 ( my own phones ) contract with TalkTalk. Each phone has its own number.
    I like to cancel one of the phone ( I use WhatsApp with this phone) contract and transfer the number to the phone ( no WhatsApp is installed) I am going to keep.
    Please tell me what I need to do.

      Hi Tony,
      Many thanks for your comment. In the first instance, I’d probably get in contact with TalkTalk customer support to see if they’re able to arrange this for you. If they aren’t, you can achieve the same outcome using a PAC Code but you will need to port your phone number out to another mobile network before porting it back in (e.g. grab a free SIM card from another mobile network, port your phone number out to that and then back into your new TalkTalk Mobile SIM).
      Hope this helps,

    Thank you for publishing these pages – It had partially helped me. I have recently transferred a mobile number from TalkTalk to Talkmobile using their PAC. Unfortunately it then took 3 months of fighting TalkTalk for them to close my account as they claimed the number hadn’t been disconnected…

    My currently problem is the opposite. I transferred the number from TalkTalk to Three, but Three claim the PAC is not linked to a mobile number. TalkTalk has disconnected the number, saying it was successfully transferred. This is my ex-business number, so I was keen to keep it. Who is responsible for ensuring the PAC is linked to the number? Both parties blame each other…

      Hi Nigel,
      Sorry to hear about the problems you’ve faced transferring phone numbers from TalkTalk Mobile to Talkmobile & Three. It looks like some really strange things are happening over at TalkTalk (whether this is due to problems with their system or with their customer service, I’m not sure).
      Typically, I’d say the destination network (in this case, Three) is responsible for the number moving over successfully to their network. Hence, I normally advise people to contact their new mobile network first. In your case, it sounds like you’ve already done and they’ve told you it was a problem with the original PAC Code from TalkTalk Mobile. In this case, the responsibility would fall with TalkTalk as it’s their legal obligation to provide you with a PAC Code that works!
      Unfortunately, if the two networks continue blaming each other for this mistake, I’m unable to really help you out much further except from to suggest you make a formal complaint in writing to both parties. But hopefully this gives you a good idea of the responsibilities held by each party, and best of luck resolving it with TalkTalk & Three.

    I have recently transferred from Tesco to Talktalk mobile (last Monday) and for 2days I could make phone calls but not receive them. Dialing my number from my landline gave varying results from “You have dialed an incorrect number” to 2 ring tones then disconnected tone then “this number is not receiving calls at the moment”.
    Due to 2days of frustration I demanded the PAC code back and Transferred back to Tesco but the problem remained even with Tesco.
    Now a further 2 days without incoming calls (except from a friend with a Tesco SIM) I am again totaly frustrated.
    I have complained bitterly to tesco but still waiting. can you make any suggestions
    Regard
    Harry

    About 15 years ago a former colleague bought a batch of Orange PAYG mobiles for office use. These were subsequently replaced by contract mobiles and the PAYG mobiles were given to the staff.
    I kept mine for personal use when I retired and I have used it ever since.
    I have now bought a smart phone on talktalk network and I wish to transfer the number from the old phone. I have many contacts who have my number.
    I am having difficulty getting the PAC number from Orange (now EE).
    Can you help please?

    • Ken replied:

      Hi Stuart,
      Thank for your comment! Could you kindly elaborate a little on what problems you’re having getting a PAC Code from Orange? It should simply be a matter of calling Orange on 450 and then going through security to get your PAC Code (for PAYG they should ask you for some details about recent top-ups, etc).

    I contacted talk talk on Wednesday AM and provided my Vodafone PAC code, I was told it would take two working days to transfer my number. I had service via the new talk talk sim until Friday at 2pm and since then absolutely nothing at all on either number. Spoke to talk talk yesterday on my partners phone and I am now waiting for a call back which will take two days. Very disappointed. At home with two kids and no way of contacting anyone.

      Hi Claire,
      Sorry to hear about your problems transferring a phone number from Vodafone to TalkTalk. Unfortunately, I’m really not sure what has happened in this case but it sounds like there has been a screw-up on TalkTalk’s end. I’d consider making a complaint to them in writing – aside from that, they’ll be the people you need to speak to in order to fix this issue.
