If you want to find out how the original block was assigned you can look up the NXX type of the thousand block in BIRRDS. I don't believe that field carries over to the LERG report but it is tracked and its the only database I know of that keeps a history of records.

I am hoping the group can help me out or point me in the right direction. I need to get historical information on ported numbers. If the number was ported to a mobile operator from a landline and if that number was ever ported back to a landline. I believe iconectiv now manages this but I would like to go back to when number porting stated for mobile within the US. I did find a handful of 3rd parties had this information, but I would like to license from the direct source if possible _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
