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.
