All of this has happened within Texas (from 1983 onward): 713/409 split occurring without N0X/N1X prefixes. 214 getting N0X/N1X prefixes (214/903 split coming up later). 512 soon to be getting N0X/N1X prefixes (new requirement of 1+512+7D for toll calls within it). 214 and 512 are apparently able to get N0X/N1X prefixes, but 713 was not?
