As soon as the LNP request is submitted to QuestBlue, an LOA (Letter of Authorization) and LSR (Local Service Request) are generated and sent
to a National Third Party that facilitates porting between carriers. The third part will then send the LSR to the current carrier of the number,
which we refer to as the "losing carrier." The losing carrier will check the account information with their Customer Service Record (CSR), and
if everything matches, an FOC date will be set. The FOC is a "Firm Order Confirmation" and this is the date that the losing carrier has agreed to
release the number to QuestBlue. Once the losing carrier releases the number on the FOC date, the process will be complete.
