Hi ​@TDPMCG79,

Thank you so much for bringing this to our attention, I'm sorry to hear you're having trouble using your PAC code.

Please double-check that:

1.The PAC code is still valid, as PACs expire after 30 days.
You're entering the correct mobile number that the PAC was issued for.

2.If you're switching to iD Mobile after purchase, you're using the transaction number that begins with a "4", which can be found in your Order Complete email, Welcome to iD email, or invoice.

If you're still receiving an error after checking the above, please let us know:

-Whether you're moving your number to iD Mobile or from iD Mobile to another network
-Any error message you're seeing
-Whether the PAC has been accepted previously

Alternatively if this does not solve the issue, reach out to us through our live chat portal using this link:
