 Some networks transmit in addition to the SID an MCC and/or MNC number. The OpenCellID back end ignores this information because it is not clearly specified and if present, then redundant.

 ===System Identification (SID)===

-|The SID (System Identification Number) is a 15 bit number (0-32,767) transmitted by base stations that identifies a wireless system that conforms to a TIA cellular or PCS standard. The SID is used by mobiles to recognize when they are in their home system (e.g. it controls the "roam" light). Some newer phones may maintain a list of "preferred" systems identified by their SID code. The SID may also modify some signaling messages that are transmitted by mobiles.

-In the wireless network, the SID is used for billing purposes, as a unique identification of the system that is serving a mobile (and that thus must be compensated for services provided to roamers). Since it is easier to transmit a 16 bit number on a network, a new range of SID's are available for network purposes only (32,768-65,535). Some of these are used as BIDs (Billing Identifiers), and are used to discriminate between different portions of a system for accounting purposes.

 SID codes are assigned by the national telecom regulator, a designated organization or, failing that, by IFAST if the national authority is unwilling or unable to perform this task or if the operator wants a range directly from IFAST (e.g. a mobile satellite operator).  If a country does not have a SID range, or needs a larger range, they can apply to the IFAST to have one of the reserved ranges allocated. Not every country that has been assigned a SID range is actually using it (for example, GSM and NMT systems do not use the SID identifier). IFAST has been allocating SID ranges since November 1997. Prior to that, SID ranges were allocated by TIA subcommittee TR-45.2.

 Each local mobile network is allocated with one SID and the specific number allocated to each local network is specified by the network provider.
 Network Identity Number is made up of 16 bits, with 0 and 65535 reserved. 0 is used to represent those base stations in a certain SID area not belonging to a specific NID area. 65535 is used to indicate that a mobile user can roam in the whole SID area.
 For a CDMA network side, there is no concept of NID, but an exchange number (one byte), which is used to identify the network equipment where a user is located.
