You can use a filter to pull up all of the contacts and companies in a single zip code. If you go to your contact list, on the left side you’ll see a section “Filters & Sorting.” At the bottom of that section, select “Add a filter.”

In the dialog that appears, select “Address - Zip” “contains” and then enter the desired zip code. When you apply that filter, it’ll pull up a list of everyone with that zip code saved as the address.
