Whether you're joining iD Mobile or leaving for another network, it's a straightforward process to keep your existing phone number.

iD PAC CodeIf you're leaving iD to join another network, or if you're leaving another network in order to join iD, it's super easy to keep your current phone number.

All you'll need to do is to request a PAC Code. It's totally free and the entire process of transferring your phone number should normally take no longer than one working day.

For detailed instructions, please choose the option that best applies to you:

Leaving iD For Another Network

iD Mobile

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

There are three ways to request an iD PAC Code:

  1. Online: You can get a PAC Code from iD by logging in to the iD Mobile Account website. Once you've logged in, go to My Account > End my plan.
  2. By Text Message: You can get an iD Mobile 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 iD.
  3. By Phone: You can get a PAC Code by calling iD Mobile. To do this, call them on 7777 using your iD handset. Alternatively, dial 0333 003 7777 from any other phone. You'll need to call during iD's opening hours (Monday-Friday 8am-8pm, Saturday 8am-8pm, Sunday 8am-8pm).

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

Once you have your iD Mobile PAC Code, you'll need to provide it to your new mobile network operator. For detailed instructions, please select your new mobile network from the following dropdown menu:

iD STAC Code (Leave iD Without Keeping Your Number)

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

  1. Online: You can get a STAC Code from iD by logging in to the iD Mobile Account website. After logging in, go to My Account > End my plan.
  2. By Text Message: You can get an iD Mobile 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 iD.
  3. By Phone: You can get a STAC Code by calling iD Mobile. Call them on 7777 using your iD handset. Alternatively, dial 0333 003 7777 from any other phone. You'll need to call during iD's opening hours (Monday-Friday 8am-8pm, Saturday 8am-8pm, Sunday 8am-8pm).

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 iD STAC Code.

Joining iD From Another Network

iD Mobile

If you're joining iD 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 iD Mobile.

After getting a PAC Code from your old network, you should order your new phone or SIM card directly from iD'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 iD 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, your PAC Code should be submitted through iD Mobile's online form. Alternatively, you can give the PAC Code to iD Mobile by calling 7777 on your iD Mobile handset. You can also call 0333 003 7777 from any other phone.

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

If your PAC Code is provided before 6pm, 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 6pm 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 iD 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 iD

  • I wanted to change a pay as you go ID account to a pay monthly and keep my number but was told this is not possible. When I suggested I take my number to a new provider using a pac code and then transfer it back to an ID pay monthly account using a pac code again they said it wasn’t possible either. Is this true?

    Tsai transferred a phone number within iD Mobile.

    • Hi Tsai,
      Thanks for your comment. There’s absolutely nothing to stop you from porting your iD Mobile phone number out to another network, and then back in to a new Pay Monthly account 🙂 You can get a free Pay As You Go SIM card for this purpose here.
      Most good mobile networks should normally allow you to upgrade directly without needing to port your phone number to another network first, so I think this is simply a case of iD Mobile’s IT infrastructure being a bit behind the times!

  • I want to transfer to ID from EE. I have sent a disconnection request to EE, so my contract will end once this final month is up. I have obtained the PAC code from EE, and I was told I have to use this within 28 days otherwise my contact with them will automatically restart and I’ll have to wait another month. However, I am currently abroad – so I want to buy an ID sim (a sim only monthly deal), use the PAC code to transfer my number to the ID sim, and only later put the sim in my phone once I return home. Is this possible, or would I have to put the new ID sim in my phone first to activate it or something, before using the PAC code?

    B transferred a phone number from EE to iD Mobile.

    • Hi B,
      Thanks for your comment. You’re right in saying that a PAC Code is only valid for 30 days (which means you’ll need to give it to your new mobile network several days before this to ensure your phone number is moved over during this time). If it expires, you’ll need to request a new PAC Code from EE.
      With regards to your iD Mobile SIM card, it should be possible to transfer the phone number to it providing it has been activated. However, I don’t know enough about the specifics of how iD Mobile works (e.g. whether the SIM cards are automatically activated, or whether it depends on you putting the SIM card in your phone first). This is probably something best answered by iD Mobile Customer Services!

  • My daughter has been with virgin mobile for 4 months now I have taken over the phone and she has a new phone and I have been with I’d my question is can I now ask virgin to keep my old number from my old phone which was with id

    Melv transferred a phone number from iD Mobile to Virgin Mobile.

    • Hi Melv,
      Thanks for your comment. Is this simply a matter of transferring your phone number from iD Mobile to Virgin? If so, there shouldn’t be a problem doing this regardless of how long the existing contract on Virgin Mobile has been held.
      Hope this helps,
      Ken
