You had me intrigued as to what the purpose of this number really was, and now I know. Thanks to Wikipedia:
"One number provided by all carriers in area code 700 is 700-555-4141, which plays a recording identifying the carrier handling long distance and international calls. While this will not work with most cellular and VOIP systems (where the long distance carrier is part of the primary service) this identification may help traditional land line consumers who have been fraudulently slammed into a new carrier."
What I stated still stands though, as a service provider, FPL can route whatever number they want to whichever carrier they want. This number is used for POTS customers to determine their LD carrier.
