We call this "The New Jersey Plan", because New Jersey never had 1 + 7D within the area code. It was the Bellcore recommended plan, but it met with objections all over the country. All of the following places have, within the past few years, either gone to or announced 1 + 10D within the NPA: Dallas-Fort Worth, Northern Virginia, Maryland, Toronto, Georgia, North Carolina, Alabama, San Antonio, Detroit, Arizona Philadelphia dropped the "1", but it is a relatively small area code, close enough to New Jersey to have been able to get away with the New Jersey plan. Arizona announced 7D, and had so many objections they changed to 1 + 10D. Here in Massachusetts, dropping 1+ has been mentioned, but it hasn't been mentioned loudly and definitely enough yet to attract attention. In 508, 7D couldn't happen until the SxS exchanges, of which there are still a large number, are all gone. The Washington, DC, area has the best plan: 7D is local within your own NPA (whether that be 202, 703, or 301); 10D is local to one of the other two NPAs; and 1 + 10D is toll, either within your own NPA or to one of the other NPAs. 1 + 10D is accepted for local calls to other NPAs, and the call gets routed and billed the same as if you had dialed just 10D. I wish that would become the nationwide plan. Regards, john
