Fortunately, most denials can be avoided by paying careful attention to the information requested for the transfer. The most common avoidable reasons for denial are:
Number not active: The phone number must be active with your previous service provider for the port to be successful. Don’t cancel your current service until the transfer is complete.
Name/Address mismatch: The name and address must match what’s in the records of the previous service provider.
No PIN/account number: For wireless numbers, the account number and PIN associated with the account are required for porting approval.
No account number/password: For some providers, the account number and password are required for porting to be completed.
