A while ago we had a discussion on CO's that straddle area code boundaries and are dialable as more than one. If you remember, we found one here in the Omaha area which was -- in SOME cases -- dialable either as 402 or 712. I recently returned from a trip to the Black Hills area of South Dakota. (Deadwood: Las Vegas of the Midwest. ;-) I stumbled upon many examples of CO's split between the 308/605 codes or the 402/605 codes. I don't know how many of these there are. There may be hundreds. I saw more in the local phone books than I can remember. These were cases where there are communities right on or near the Nebraska - South Dakota border. They often appear in such form as 'Whatnot, SD' and 'South Whatnot, NE' or 'Cornholdt, NE' and 'North Cornholdt, SD'. (I forget the actual names, but these are typical.) These communities are VERY small. If you think Omaha is out in the toolies ... we are talking major sticks here. These towns are only a few hundred in population, if that. From the limited amount of dorking around I found time and place to do, I determined that these were all SxS offices (with some REALLY funky ringback and busy tones) which maybe served 100 or so subscribers on both sides of the border. These offices came nowhere near to filling up a complete 1000's group out of an office code. In some cases, the NNX were the same in both area codes, in some, they were different. In every case, the same lines (and vacant levels, etc.) could be reached via either AC. My conclusion is that in the 48 states, there are potentially thousands of examples of 'split' central offices if we consider all of the rural communities that are adjacent to or straddle state lines.

Antioch, IL was 312-395. North Antioch, WI is 414-396, but was dialable from *Antioch only* as 396+4D. To reach the *real* 312-396 residents of the village of Antioch had to dial one plus. 414-396 is Illinois Bell's one incursion into the 414 area. Now, Antioch is 708, but so is Blue Island, IL where the 'real' 708-396 lives. I don't know what they do up there now. PAT]

Ah, how different rural life is from urban life! Here in Chicago the prefixes dialable as either 312 or 708 are in CO's whose area coverage is not split, and prefixes in CO's whose coverage areas *are* split are dialable only as one area code or the other, not as both, and require eleven digits to be reached from the other side of the line and the correct area code to be reached from the rest of the world. For examples, (708) 591 [choke prefix], (708) 796 [customer name and address], and (708) 976 all are aliases for their area code 312 namesakes and are switched in the Canal East office. I believe that anyone outside area code 708 must dial these as 312; inside 708 dialing 1312+7D to reach them is forbidden, and only 7D will work. <(708) 950 might similarly be an alias for (312) 950, but it might be separate; one would never dial another area code's 950 anyway.> On the other hand, (708) 825 and (312) 825 are both wired from the Park Ridge CO, but neither is an alias for the other as a dialing convenience; they are two separate prefixes. I wouldn't be at all surprised if some larger customers had identical numbers on (708) 825 and (312) 825 assigned to them, but both must be wired in or one must be forwarded to the other if they are to ring in the same place. And yes, to call between the two 825's one has to dial eleven digits. I imagine that rural CO's straddle an area code boundary only when they spread across a state line; an intrastate area code boundary in a rural area just about never would divide a CO's territory.
