NPAs don’t cross state lines, but LATAs do cross state lines. Any data such as that on the FreeSWITCH website would be sample data. The official sources for that data would be NANPA… you can get something close from telcodata.us From: FreeSWITCH-users <freeswitch-users-bounces@lists.freeswitch.org> On Behalf Of Avi Marcus Sent: Wednesday, October 3, 2018 1:16 PM To: FreeSWITCH Users Help <FreeSWITCH-users@lists.freeswitch.org> Subject: Re: [Freeswitch-users] npa_nxx_company_ocn database? Ah, it was linked from mod_cidlookup page: http://files.freeswitch.org/npa-nxx-companytype-ocn.csv But `curl --head` tells me: Last-Modified: Wed, 08 Jul 2009 01:19:32 GMT Seems my carriers only provide intra or interstate, no LATA calculations necessary. Anyone have an updated npa/nxx per state list? Do any npa's cross state lines? Perhaps I only need the much smaller NPA list. According to that 2009 data, none do. -Avi Marcus 1-718-989-9485 (USA) 02-372-1570 (Israel) 020-3298-2875 (UK) On Wed, Oct 3, 2018 at 9:04 PM Avi Marcus <avi@avimarcus.net <mailto:avi@avimarcus.net> > wrote: mod_lcr mentions using npa_nxx_company_ocn to determine inter/intra-state or inter/intra-lata calls.
