This article explains how to find and verify postal codes and area codes online. Postal codes and zip codes are numeric codes used to facilitate mail delivery, and area codes are used to specify a geographic region when dialing a phone number.

You can use various websites and search engines to find a zip code.

If you have an address or partial address, you can find the ZIP code using USPS Zip Code Lookup, a tool on the U.S. Postal Service website. You can also search by city or state, or find all the cities that are part of a particular ZIP code.

You can also use various search engines to find zip codes. For example, with Google, to perform a zip code search by address, type in what you know about the address to see a map of the location with the zip code included.
