Actually, getting the precise zone is quite important because of the zone-based
scoring (1 pt same zone/3 points other zones). I bet that if you are in zone
10, your score will be higher by 15-20% compared to zone 6.
In the past, the ARRL had a list which precisely defined what parts of which
states were in which zone. No part of AZ was in zone 10 ! It seems that the
list was removed when the ARRL website was revamped, but you can still get it
at:

Then I found
http://www.arrl.org/contest-update-issues%3Fissue%3D2010-06-09
which references a map
http://www.itu.int/ITU-R/terrestrial/broadcast/hf/refdata/maps/index.html
and "corner coordinates" at
http://www.itu.int/ITU-R/terrestrial/broadcast/hf/refdata/reftables/ciraf.txt
But I think those are actually "test points" for evaluating signal strengths,
and not on the boundaries of zones. If you plot some of them (for example the
SW quadrant of zone 8 where I am), you will see they are not at all the
boundaries. Also notice for example that the east boundary of zone 7 does not
correspond to the west boundary of 8 in that list.
So which one should we use? I'd be happy to put myself in zone 7 according to
the "corner coordinates" referenced and get a 20% increase in score :)
