The official website of the U.S. Postal Service has a ZIP code finder that enables individuals to find ZIP codes for a particular town or city. Visitors can type in a particular address, city name and state, after which the website pulls up a list of ZIP codes.
Another search engine allows visitors to type in a known ZIP code in order to match it with a particular town or city. The website also features a company search engine where individuals can search for the ZIP code of a business by entering the business' name, street address, city and state.
