What is a Zip Code?
A zip code is a numerical code used by the United States Postal Service (USPS) to identify specific geographic regions within the country. Standing for “Zone Improvement Plan,” zip codes were first introduced in 1963 to improve mail delivery efficiency. They consist of five digits, with an optional additional four digits for more precise location identification. These codes enable the USPS to sort and route mail accurately, ensuring prompt delivery.
The Structure of AZ Zip Codes:
Arizona zip codes follow the same structure as zip codes across the United States. The first digit of an AZ zip code represents one of ten geographic regions. The subsequent two digits narrow down the location further, indicating specific cities or towns. The final two digits provide more precise information, such as neighborhoods or even individual streets.
