If you want to go all the way back, the 0th split was probably 201/609. The earliest NPA maps apparently had all of New Jersey in 201, but they split it before many people even had DDD. One thing I've always wondered about was why 201 is a single LATA, while 609, which has about half as many phones and prefixes, it split into two. I suppose it's because 609 has a strip of nearly uninhabited Pine Barrens down the middle which makes it easy to split, but it's a pain. The eastern 609 LATA is a tiny strip running about 65 miles down the coast with the only town of any size being Atlantic City. I happen to have a beach house near there and almost every call I make is an inter-lata toll call. At least they all go toward my Sprint Plus volume discount. This situation also makes for some interesting dialing. From my parents' house in Princeton NJ in the western 609 LATA, when you dial a regular seven digit number it might be: * a free local intra-lata call * a free local inter-lata call, since local calls into adjacent prefixes in 201 can still be dialed without the area code * an intra-lata toll call * an inter-lata toll call It makes it hard to tell how much to expect to pay. Local calls across the NPA boundary can be dialed without the area code all along the line in New Jersey, and since there are still several NNX prefixes that are assigned neither in 201 nor 609, this seems unlikely to change. 609 does not have NXX prefixes but 201 does, and in at least one case an NXX prefix in Toms River (201) is dialable from Barnegat (609) without an area code; I guess they had to put in a special case timeout.
