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.

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.
