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

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
