Can 4×4 posts support a deck
In the past, many decks were built with 4×4 support posts (also called structural posts). But these can bow seriously, even if a deck is only 3 feet off the ground. For that reason, we strongly recommend that you use 6x6s instead, even if your building department does not demand them.

Do 4×4 posts need concrete
Most use concrete to create leverage. The main reason is the post length of choice for fence companies is often a 4″ x 4″ x 8′. As a result, the fence post is only two feet in the ground on a six-foot in height wood fence. Hence the use of concrete.
