ROAMING ZONE SYSTEM
ID's (SID LIST)
System
Identification Numbers, or SID, are numeric identifiers used by
cellular systems to specify the home system of a wireless carrier, and
by the cellular device to determine its roaming status. Our lists
are updated as changes are
discovered. Some entries are in the name of the legal office that
represents the wireless carrier. Administration of SID's is maintained in
the private sector, not by the FCC.
FCC's
Administration of Cellular SID's:
The
administration of Cellular SID's was transferred to the private sector
on October 1, 2003. With the transfer of this responsibility, the SID
was removed from the cellular license. Cellular licensees seeking a new
SID assignment, an additional SID assignment, or licensees that have
ceased using an assigned SID, will be required to make their request /
notification through one of the recognized SID Administrators to
perform Cellular SID administration. Each organization will operate
under the general guidelines developed by the FCC and the cellular
industry.
