Duplex - Bob Goudreau wrote (in reply to Earle Robinson): Check out the WTNG for details on the incredible amount of numbering changes that have taken place in Europe in recent years. Meanwhile, in the NANP, there are tens of millions of people who still have the same area code that they had 30 or 40 years ago. Even the ones who have encountered an area code split got to keep their local numbers. And, with overlay area codes now the most common way to expand the numbering space, most of us will probably never be forced to change our numbers again.That is, most of us in the NANP will (probably) never be forced tochange our numbers again, until that time "sometime" in the future,when the NANP might ultimately have to expand to something"longer-than-ten-digits", by adding one (or two) digits somewherewithin the existing ten-digit number, to create a subsequent eleven(or twelve) digit NANP number. That number "change" is going to affectANY/EVERY one in the NANP in one big swoop, as well as anyone whoneeds to call NANP-based numbers from outside of the NANP. But therewill be a "permissive/parallel" dialing period for both intra-NANPusage, as well as "intl/ovs"-to-NANP calling.But current projections have that an expansion to an eleven or eventwelve digit NANP based number is now anticipated to happen in the2040 to 2050 time frame. And IMO, as time continues, that 2040/2050timeframe will be pushed out even further into the future!Mark J. Cucciamcuccia@tulane.eduNew Orleans LA CSA (in the LAND of DIXIE!)
