71111

71111 is a three-digit zip code prefix used by the United States Postal Service. In the US zip code system, the first digit represents a group of nine regional zones, also known as "zones." The number 7 corresponds to a zone encompassing the southern and southwestern regions of the country. The second and third digits, 111, identify a specific carrier route within this zone.

Zip codes with the prefix 711 are primarily found in Arizona, but can also be located in California, Nevada, New Mexico, and Texas. These areas encompass various regions, including deserts, plateaus, and mountain ranges. Some of the major cities within this zone include Phoenix, Tucson, and Albuquerque.

Zip code 71111 itself is not a widely used or recognized code, suggesting it may be an inactive or obsolete designation. However, zip code 711 is used by several cities in the southwestern United States. The geographic range and use of zip code 711 can vary widely, but it generally covers areas within Arizona, California, Nevada, New Mexico, and Texas.

The assignment of zip codes is managed by the United States Postal Service, and new codes are sometimes created or retired in response to population growth, urbanization, or changes in geographic boundaries. The USPS updates and revises zip code lists regularly, so some sources may not reflect the most current information on this topic. As a result, information on specific zip code designations can become outdated or incomplete over time.
