How do you find a postal code directory?

Find a postal code directory by visiting websites such as USPS.com, UnitedStatesZipCodes.org, DMOZ.org or GlobeFeed.com, as of 2015. Some sites only feature a list of the postal codes by country, while others allow the user to search for a region to view all of its active postal codes.

USPS.com features a ZIP code search tool that allows a user to look up a ZIP code based on a residential or business address as well as view a list of all cities within a given ZIP code. As the United States Postal Service operates the site, results also include the additional four-digit ZIP code classifications and up-to-date occupant information. The website UnitedStatesZipCodes.org features a map of the United States with ZIP code information, which allows users to navigate manually to find a specific ZIP code. It also contains a search tool to access a specific code quickly.

GlobeFeed.com contains a postal code directory for several countries, including the United States and Canada. Clicking on the country's name loads a list of all of its postal or ZIP codes. DMOZ.com doesn't host a directory of postal codes but instead links to the official postal organizations of various countries. This ensures that the user accesses the most recent and accurate information.
