When DDD came to Atlantic City, NJ in 1961, besides detailed instructions on how to use Area Codes, etc, we were told that Area Codes were not required to any call in NJ, although the map showed the 201/609 split. There was one list of central office codes and the approximate name of the locality served. A few years later, we were told to start using 201 for calls to Northern NJ. I have since heard that the algorithm for Area Codes was orginally something like this- 1. States with one area code had its second digit as 0; states with multiple area codes had all its area codes with a second digit as 1. 2. Lower numbers were reserved for areas with a large number of phones, so the time to dial NYC (212) for example took less time than less populated areas (like the state of Wyoming). As I further heard, NJ was originally just one area code (201), but it got split before DDD really got moving. -- Stan Krieger Summit NJ
