Not many are aware of it, but there was a proposed NPA assignment in
1946/47, but this one wasn't adopted, of course. (The original
assignment of 86 NPA which has been the one that has actually been
built upon was in October 1947).

In the following proposed assignments, the N0X form was still assigned to
states which needed only one NPA code, and the N1N form was assigned to
states which needed several codes. Canada was treated as "single state"
which needed several area codes and were assigned ones of the form N10.

Any state which needed more-than-one code were assigned CONSECUTIVE codes
as seen below!

I've had a map of this proposed (but never adopted) assignment somewhere
in my historical records (I think it was in an old issue of Bell Telephone
Magazine or Bell Labs Record from the mid-to-late 1940's), and finally got
around to typing it into a .txt file.

they will be used. Due to technical difficulties earlier today this is
still pending distribution to the mailing list and I hope by the time
you receive this issue of the Digest you will have also received the
special mailing prepared by Mark, or if it has not come to you that it
will arrive in your mailbox by Tuesday morning. PAT]

Mark J. Cuccia's interesting message showed a first cut at NPA assignments,
never adopted. My provincial reaction was to look for my state, Massachusetts,
in the list. Well! There are 47 states listed (out of 48 in the union as of
1947), and Massachusetts, the site of the first phone call, is missing.

Was it missing from the list he transcribed, or was this a transmission error?
