Definitions of Status

  • PRIMARY: Refers to the main name of the city, typically its official designation. Although the city might have an ACCEPTABLE alternative name, the primary name remains the official one.
  • ACCEPTABLE: Indicates a suitable alternative city name. Commonly abbreviated city names are often listed as unacceptable because abbreviations are not considered an acceptable city name format.
  • IMPROPER/NOT ACCEPTABLE: Denotes that an inappropriate city name was entered or received based on the provided information.
  • UNIQUE: Assigned to a business, government agency, or entity with a significant mail volume. This designation depends on the average daily volume of letter-sized mail received, the availability of ZIP code numbers in the postal area, and a cost-benefit analysis by the postal service.

The ZIP Code System in the United States - Código postal

Postal codes, known as ZIP codes, are used by the United States Postal Service (USPS) since 1963. "ZIP" stands for "Zone Improvement Plan," a term chosen to suggest that mail travels more efficiently and, therefore, faster when senders include the ZIP code in the address. The basic format consists of five numeric digits. An extended ZIP+4 code, introduced in 1983, includes the five-digit ZIP code, a hyphen, and four additional digits that specify a more precise location within a given ZIP code.

Understanding the Structure of ZIP Codes

The Five-Digit Code: The initial five digits of the ZIP code identify a specific area:

  • The first digit represents a group of U.S. states.
  • The second and third digits designate a region within the group.
  • The fourth and fifth digits pinpoint a specific post office or delivery area.

ZIP+4 Extended Code: Introduced to improve accuracy and efficiency, this extended code includes:

  • The original five-digit ZIP code.
  • A hyphen.
  • Four additional digits that designate a more specific location, such as a city block, building, or company department.

Why ZIP Codes Matter in the United States

ZIP codes are crucial for efficient mail delivery and are used extensively in demographic research, marketing, and logistics. They help:
