the zip code regex want looks this:

\d{5}(?:-\d{4})?

what have there can collapsed down [d]-[d], , further d-d, meaning match 2 literal d characters separated hyphen, not you're after.

in regex provided, i've made second part of zip code optional (as in many cases), meaning you'll match both partial (5-digit) , complete (9-digit) zip codes. sure validate zip code, isn't i'd recommend doing regex.
