I know that FCC has a website http://apps.fcc.gov/cgb/form499/499a.cfm, but there are only companies names. In Poland we have similar database on our "FCC" website - UKE ( Office of Electronic Communications ), but we can find to whom belongs allocated telephone numbers. For example: area code 12 + number starts at 200 -> 12200 and we have -> area code '12' | allocated pool 'SPQM=200(1,3,6,8,0)' | area 'Krakow' | owner 'TP S.A' Where can I find that kind of information? Thanks in advance for help. -- Jarek Kasjaniuk
