Pointless V&H statistics are my business. :-).  Attached are a list of
LATAs and the number of exchanges in each.  It is possible that there
are minor errors here, since this information is transcribed from a
tape to my database, and in doing 50,000+ of these some errors will
creep in.

But, it should be close.

The smallest LATAs have just one entry:

999 is in NPA 504 and is labelled as "OFF SHORE". I assume that it is the
    offshore drilling platforms.
930 is EPPES FORK, VA.  Anyone know anything about it?
921 is FISHERS ISLAND, NY.  One exchange on one island.
981 is in Utah.  It includes three exchanges, for HALCHITA, MONUMENT
    VALLEY, and MONTEZUMA CREEK-ANETH.  My guess is a small independant
    company.

The largest is 730, the monster that takes in a large part of southern
    California and a piece of Arizona.

A complete list of NPA/LATA combinations is below the count list.
