I actually just added "npa-exchange-state-ratecenter <https://www.telcodata.us/data-downloads?file=npa-exchange-state-ratecenter>" on the web (npa-exchange-state-ratecenter-ocn-company-city-county-zip-lat-lon-byratecenter.csv on FTP) for this one, if that does what you need it's not "authoritative" but nothing really is. It's derived from the ILEC end office lat/lon in the rate center. It's not perfect, but if you launched a large enough nuke at the coordinates I provide, I'm confident it'd hit whatever you're looking at. ?

Haven't looked in awhile, but telcodata.us <http://telcodata.us/> has a bit of that information.

Is there an authoritative source for rate center latitude and longitude?
Is there a free source for this data?
I'm aware that BIRRDS/LERG has the Switch CLLI coordinates, but I don't know if the rate center virtual coordinates are also there. NANPA said, "NANPA doesn?t have this information. We suggest you check with a vendor who creates rate center maps, but we can?t recommend one."
Is rate center data centralized, or invented by carriers and 3rd parties? _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org <mailto:VoiceOps at voiceops.org> https://puck.nether.net/mailman/listinfo/voiceops
