The pseudo-area-codes of form 52x for Mexico are not in use yet, and cannot be used until the system can handle area codes of form NXX, not just of form N0X/N1X. Area codes 706 and 905, which had been used (at least from the U.S.) for parts of Mexico, were discontinued (and have since been announced for use elsewhere), and instead of these codes it is now necessary to use 011-52- ... to call Mexico. There is some confusion, at least on my part, about those 52x codes. If they will indeed be dialed like area codes, it would go against the idea of using NN0 codes as the first slew of NNX area codes: being able to keep 1+7D for intra-NPA long distance in some areas after the NNX area codes begin (areas keeping such 1+7D usage would have to disallow prefixes of NN0 form).
