Taylorsville City Administrator John Inch Morgan said he received a handful of calls Monday from upset residents in the 84129 ZIP code asking what was going on, with at least one caller wondering if municipal boundaries were being tweaked to put him in West Valley City.
Morgan said no one will end up in a new city and the Post Office is sending out an apology to the 84129 addressees. In addition, surveys will be sent to 84128 residents.
For each ZIP code, the Postal Service designates a "preferred city." The post office at 3490 S. 4400 West is listed as a branch of the Salt Lake City Post Office.
West Valley City administrators say in a report recommending a designation change that it is often difficult or impossible to use an address different from the preferred city when ordering products online or shipping goods.
"Furthermore, the database of preferred cities is used frequently by businesses in researching potential locations for expansion or relocation," the report says. "As a result, West Valley City does not obtain the name recognition that would ordinarily come to such a large community."
West Valley is Utah's second-largest city and has a population of about 133,000.
In Taylorsville, 84129 came into use on July 1, 2011, and took the place of the 84118, 84119 and 84084 ZIP codes in that city. Officials there had lobbied for years for the unified ZIP code as a way to sell Taylorsville as a separate entity from neighboring communities and to gather more accurate demographic information.
