Yep, I imagined as such. I was wondering more how one would deal with this when the NPA's are so full they don't have the luxury of making certain exchanges unique across neighboring NPA's? I imagine that one would then be required to dial the whole 10 (or 11) digits. I don't know how often this would be necessary, i.e., is this sharing of prefixes across neighboring NPA's very sacred, or just a luxury of having enough exchanges to spare? Thanks for your input, Thomas! ben ullrich consider my words disclaimed,if you consider them at all sybase, inc., emeryville, ca "When you deal with human beings, a certain +1 (415) 596 - 3500 amount of nonsense is inevitable." - mike trout ben@sybase.com {pyramid,pacbell,sun,lll-tis}!sybase!ben [Moderator's Note: It used to be quite common that prefixes were never duplicated in neighboring area codes; i.e. nothing in northern Indiana was ever used in Chicago or Illinois suburbs, etc. 312-396 was never used here since folks in Antioch, IL had seven digit dialing to their neighbors in North Antioch, WI (414-396). Illinois Bell quit worrying about it years ago as the reserve of prefixes ran short. PT]
