Sec. 22.941  System identification numbers.

    System identification numbers (SIDs) are 15 bit binary numbers 
assigned to cellular systems. SIDs are transmitted by the cellular 
systems so that cellular mobile stations can determine whether the 
system through which they are communicating is a system to which they 
subscribe, or whether they are considered by the system to be roamers.
    (a) The FCC assigns one SID to each cellular system on its initial 
authorization. Cellular systems may transmit only their assigned SID(s) 
and/or the SIDs assigned to other cellular systems. A cellular system 
may transmit the SID assigned to another cellular system only if the 
licensee of that system concurs with such use of its assigned SID.
    (b) Licensees must notify the FCC (FCC Form 489) if their cellular 
systems transmit SIDs assigned to other cellular systems. The 
notification must indicate the concurrence of the licensee(s) of such 
other systems with this use of their assigned SID(s). The notification 
must be mailed or delivered to the filing place (see Sec. 22.106) no 
later than 15 days after the system begins transmitting the SID(s).
    (c) Licensees may request that an additional (previously unassigned) 
SID be assigned to their system by filing an application for minor 
modification of station (FCC Form ).
