Hello,

Just a quick question that I could not find an answer for anywhere on the internet. For an example, lets say a SID/NID pair of 96/5 for verizon is being used somewhere in MD, would it be possible for the SID/NID to be reused anywhere in the network? Or world for that matter? Also, can the SID itself be repeated? Thanks

To answer your question,no.TIA TR-45.2 assigned ranges to every country extant in the 1980s.
national regulators assigned individual numbers. IFAST took over in 1997. This number space is 90% utilized for country ranges, however many countries do not use all of their allocated codes so the majority of codes are not used and are not doubled up on more than one carrier
