IDentification Numbers (SID List)
System Identification Numbers, or SIDs, are numeric codes used by cellular systems to identify the home system of a wireless carrier and by the wireless device to determine its roaming status. Our lists are updated as changes are discovered. Some entries are in the name of the legal office who represents the wireless company. Entries with expiration dates may have been renewed. Note: Some of these lists are large, but we have broken them into more download-friendly sizes. |
