Transfer your mobile number from Orange to TalkTalk Mobile

Leaving Orange

How to switch from Orange and transfer my number to TalkTalk Mobile

Contact Orange to request your "Port Authorisation Code" (PAC) at the same time you give your notice of leaving. The Orange customer support line for Pay Monthly customers is 07973 100 150 (or 150 from your mobile), and for Pay As You Go customers dial 07973 100 450 (or 450 from your mobile). Orange will then send out your PAC code by post within 2 working days.

If you wish to use the 'text-to-switch' service, simply SMS text PAC to 65075 free from your Orange SIM to request a PAC code by text message and begin the porting process.

  • Orange will provide your Porting Authorisation Code (PAC) either by SMS text message, via email, or over the phone if you contact them.
  • A PAC number is valid for 30 days. If you don't use it within thirty days it will expire and you will need to request a new one.
  • Your Orange online account settings will remain active until your number has been ported over to the new network. After the transfer is complete, your account will be automatically closed.

While you wait for your Port Authorization Code from Orange, get the best TalkTalk Mobile offer for you. Many of these exclusive mobile phone deals are only available online, directly from the network providers listed here.

Got your PAC code from Orange?

Provide your PAC code from Orange to TalkTalk Mobile online who will then be able to port your existing phone number from Orange. They will tell you what day the transfer is due to take place (usually within 48 hours).

Important: Do NOT cancel your SIM only or mobile contract before switching, otherwise you may lose your existing phone number and be unable to port it over. Once you give your new network provider your PAC code, your old billing account will be closed automatically when your number is successfully ported over.

Note: Credit on Pre-Pay / PAYG (Pay-As-You-Go) accounts cannot be transferred over and so any remaining credit balance will be lost after the switch is complete. If you have any credit left, one good option is to donate it to a charity by SMS text message before porting your number.

How to switch to TalkTalk Mobile and keep my Orange number?

First get your TalkTalk Mobile package and activate your new SIM card.

Once you have done that, get the following information ready to follow the step-by-step instructions:

  • Your old Orange mobile phone number you want to keep.
  • The Porting Authorisation Code (PAC) from your previous Orange network.
  • The expiry date of the PAC number (valid for 30 days from the date of issue).
  • The temporary mobile number from your new TalkTalk Mobile SIM card activation.
  • You may also need the new TalkTalk Mobile SIM card serial number found on the back.

Your TalkTalk mobile SIM card needs to be activated before you can transfer your existing number. Once your SIM is active, you can request the transfer from your online account or by telephoning TalkTalk customer service on 2883 from your TalkTalk Mobile or 0345 172 0088 from any other phone.

Note: You may lose network service for a short period on the day of transfer. If this happens, turn your phone off and on occasionally, until you see the TalkTalk Mobile signal on your mobile phone screen. This will indicate that the transfer is complete, and you can now use your existing phone number in your new mobile network provider.

About Orange

Orange UK was a mobile network operator and a former internet service provider in the United Kingdom, launched in 1993. In 2000, it was purchased by France Télécom (now Orange S.A.), which then adopted the Orange brand for all its other mobile communications activities.

Orange UK has since merged with Deutsche Telekom's T-Mobile UK to form a joint venture, EE. EE continued to operate the Orange brand until February 2015, when new connections and upgrades on Orange tariffs were withdrawn. Existing Orange customers who wish to upgrade must switch to an EE tariff when their contract term ends, or can choose to remain on their existing Orange tariff without renewing.
