Switch from BT to iD Mobile and keep your number using a PAC code

Ofcom’s policies have made it extremely quick and easy to switch and transfer your BT number to iD Mobile.

It’s completely free to transfer your number - you simply need to request a PAC code from BT by sending a text message, which takes no more than 2 minutes to arrive. Once you’ve handed the PAC code to iD Mobile, the switching process will take no more than 1 to 2 working days to complete.

If you want to join iD Mobile and get a brand new phone number, without keeping your existing BT number, the process is almost identical - the only difference being you will need to request a STAC code instead of a PAC code.

Joining iD Mobile from BT

Joining iD Mobile and transferring your number from BT is a very easy process, and should take no more than 1 to 2 working days.

You simply need to request a free PAC code from your BT number, and hand it to iD Mobile.

You can hand your PAC code to iD Mobile at the time of ordering a new iD Mobile phone or iD Mobile SIM, or you can do this after you’ve received your order. When you choose to do this is up to you - it doesn’t make a difference.

After you’ve handed your PAC code to iD Mobile, your number will be transferred to iD Mobile within 1 to 2 working days, and your account with BT will automatically be closed.

1. Request a PAC code from BT

Requesting a PAC code from BT is quick and free. The easiest way to do this is via text:

  1. Text: From your BT number, text PAC to 65075 for free. You will receive a reply within 2 minutes, containing your PAC code
  2. Online: Login to your BT Mobile account and request a PAC code
  3. Phone: Call 150 from your BT Mobile number or 0330 1234 150 from any other number.
    • Monday to Friday: 8am - 9pm
    • Weekends and bank holidays: 8am - 8pm

You will have 30 days to hand your PAC code to iD Mobile, after which it will expire and you will need to request another one from BT.

Note: If you wish to switch to iD Mobile, but you want a brand new number without keeping your BT number, you need to request a STAC code rather than a PAC code from BT. You can do this by texting STAC to 75075 instead.

2. Order a new phone or SIM from iD Mobile

If you haven’t yet ordered a new SIM or phone with iD Mobile, you can find the cheapest iD Mobile deals through our comparison tools:

You may have the opportunity to hand your PAC code over at the time of ordering a new phone or SIM from iD Mobile. If so, you will have the option to enter your PAC code during the checkout process. Once your order arrives and you activate the SIM, the transfer process will automatically begin.

If you’re not given the opportunity to hand your PAC code to iD Mobile at the time of ordering, don’t worry. Instead, you will receive a temporary number with your new iD Mobile SIM. You will be given the opportunity to hand your PAC code to iD Mobile and transfer your BT number once your order arrives, as detailed in the next step.

Note: Apart from being slightly more convenient, it doesn’t make a difference whether you choose to hand your PAC code to iD Mobile at the order checkout or after you’ve received your order.

3. Hand the PAC code to iD Mobile

Once you have your PAC code from BT, you simply need to hand it to iD Mobile to start the transfer process.

4. Wait for the switch to iD Mobile to complete

It will take 1 to 2 working days for iD Mobile to transfer your number. Once the transfer has completed, your account with BT will automatically be closed.
