You can match up the LATA with the rate center if you look it up in LERG 8 (rate centers), but nowhere else. LERG 8 gives you the LATA, rate center abbreviation AND rate center full name, as well as the V & H coordinates for the rate center - not the CO.

You can't resolve a rate center to a LATA per se, but you can resolve an NPA to a LATA pretty easily. However, that won't help you avoid edge cases like LATAs that flow across state borders into NPAs that are otherwise 99% in some other LATA -- those do happen. For that, you'd need the LERG and/or pooling data.
I think it's more than a few edge cases, and often within the same state. NPA 805 for example is split between just about evenly between LATA 730 and 740 in California, with smidgen in LATA 734. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
