## Description

Zipcodesusa.org is an independent online resource for people seeking information about postal codes and telephone area codes in the United States. Its tools and reference material help users look up USPS ZIP codes for U.S. locations and explore ZIP codes by address, city, state, or county. The site also offers ZIP code maps, area code lookup information, and time zone details associated with ZIP codes.

Alongside its lookup resources, Zipcodesusa.org explains how ZIP codes work and describes four common categories: unique codes assigned to high-volume mail recipients, codes used exclusively for post office boxes, military ZIP codes, and standard codes for other locations. The site notes that ZIP codes support the sorting and delivery of mail and parcels by the United States Postal Service.
