Well, Cincinatti Bell (Not part of the old AT&T, and thus never actually divested) does just that in their directory. They also list a small number of prefixes right around the river that can be reached from either the Ohio(513) or Kentucky(606) side without dialing the area code. I assume they can do this as its all within their LATA. Rather a nifty service if you ask me ... I don't remember what the prefixes are, but I wonder if you could reach those numbers from outside the LATA by dialing either 513- or 606- area codes. A. Jacobson

That has been done in many places, where a local calling area straddles an area-code boundary. I lived in the Washington DC metro area for the first twenty years of my life. Throughout that period, (well, going back to when DDD and area codes first turned up!) the local calling area included all of the DC (202), and portions of MD (301) and VA (703). Calls within the local calling area could always be dialed with seven digits, even if you were crossing two area code boundaries (such as from Prince George's County, MD (East of DC) to McLean, VA (West of DC)). It used to be possible to reach numbers in the Maryland suburbs from far away by dialing either 301 or 202. In the Washington area, that has just changed. It is now necessary to dial the area code when placing local calls which cross the area code boundaries. This frees up all of the prefixes in 202 for assignment in the 301 area code. It also frees up the prefixes in the nearby Maryland suburbs for assignment within the District. They haven't needed an area code split, but they needed a dialing plan change to accomodate growth. There are probably lots of other areas where local calls which cross an area code boundary can (or could) be dialed with seven digits. Can anybody point to other places where this is/was done. Have others changed as the DC has recently? Dave Levenson Internet: dave@westmark.com Westmark, Inc.
