Code requirement for deck posts

It's been a while since I've built a deck and was wondering if the post that the beam sits on has to be 6" x 6". The last time I built one it was Ok to use 4" x 4" posts. This deck will be built in Tuftonboro.

The reason I ask is because on page 7 of the Prescriptive Residential Wood Deck Construction Guide which is based on the 2009 International Residential Code states this: "POST REQUIREMENTS....
All deck post sizes shall be 6x6 (nominal) or larger"

I don't want to make a drawing for the permit using 4" posts and find out that I need 6" posts.

Here is the Guide: http://www.awc.org/publications/dca/dca6/dca6-09.pdf
