Hi @Iamthejayjay, welcome to the community!
Once your PAC code has been submitted, it takes on average (unless another date as been preselected) 24-48 working hours for your number to transfer over.
Have you ever received a text from iD to state that the number transfer has gone through? If not, we likely haven’t received the request, and a new PAC code will need to be submitted via the link below.

If you have, your mobile number likely needs to be updated in your phone settings from the temporary iD number to the one you transferred over.
Why does the wrong number show when I make calls or texts? | iD Mobile Community
Please let us know if you have any further questions and we’d be happy to assist.
