(There are local calls between 215 and NJ, at Trenton and some points further north.) Since when has it become necessary to consider bringing N0X/N1X to Massachusetts? The 617/508 split was done only 3 years ago without N0X/N1X being in use. Yes, I know that many calling instructions will have to change later to accommodate areacodes being generalized from N0X/N1X to NXX. How soon would this begin happening (i.e. change calling instructions for this reason, NOT because that particular area is running short of NNX)? And once areacodes become NXX, would the rule still be NOT to use N0X/N1X prefixes unless NNX prefixes started running out? For those who haven't noticed: If your area has changed its calling instructions to accommodate N0X/N1X prefixes, it should already be able to accommodate NXX area codes, not just N0X/N1X area codes.
