Therefore, switching equipment could always tell if someone was dialing locally or to another area code by examining the middle digit of the first three digits. [It could have just counted digits, but how long does it wait until it decides that only 7 digits are coming?] As the population expanded, it became necessary to use zero or one in central office codes, which introduced the need of the extra 1+ so that the switch recognizes the long distance nature of the call. Some area codes have not yet expanded to fill all their central office codes (no 0/1), so they do not yet need 1+ dialing. New Jersey finally converted last July 1. When all the new central office codes (with 0/1) are exhausted, then the area code is split into two, as recently happened to New York City and to Los Angeles. Actually, I think the original poster was referring to something else (I seem to remember it was posted from Holland). That is, world dialing. There also exist country codes, which are anywhere from 1 to 3 digits. The first of the digits refer to the following locations: 1 Canada, US (Accesses the North American Numbering Plan) 2 Africa (e.g., Morocco 212, Egypt 20, Nigeria 234) 3,4 Europe (e.g., Iceland 354, Austria 43, Netherlands 31) 5 South and Central America, Mexico (e.g., Mexico 52, Argentina 54) 6 South Pacific (e.g., Philippines 63, French Polynesia 689) 7 USSR (All of it) 8 North Pacific (e.g., Japan 81, Hong Kong 852) 9 Far and Middle East (Iran 98, Kuwait 965) 0 Spare (What country is this? :-)) I think the +1 referred to in the original posting was the country code. Most USers are parochial in this regard for the same reason most don't speak other languages in addition to English: they never (well, rarely) have to. European countries are so near each other, I imagine that much international dialing occurs, so most people know about it. Almost nobody in the US even knows *how* to dial internationally (except Canada, which uses the same plan). -- ". . . and shun the frumious Bandersnatch."
