Infinite Loop of "Incorrect Zip Code" when trying to port-out my number to Visible

I am writing to address a critical issue regarding the port-out of my phone number from Xfinity to Visible. My activation attempt for the new Visible SIM card has been repeatedly blocked by an 'Incorrect Zip Code' error.

To resolve this, I have contacted Xfinity support on two separate occasions. Your representatives have confirmed that there is only one zip code associated with my account and have assured me that no port-out request is being rejected from your end. However, Visible's support team consistently reports that the porting request is being actively rejected by Xfinity, citing the incorrect zip code as the specific reason.

This has resulted in a deadlock, with each company directing me to the other without providing a viable solution. The failure to resolve this discrepancy between your systems is preventing the transfer of my number. I require a definitive resolution to this matter. Please investigate this issue internally, coordinate directly with Visible's porting department if necessary, and ensure my number is released for porting without further delay.
