Information About Johnston County Zip Code 27555, Micro


Zip code 27555 is located in Johnston County, North Carolina, and serves the very small town of Micro. Billed as the smallest town in Johnston County but with a "big heart," Micro offers an extremely quiet, close-knit rural lifestyle.

Here is a detailed breakdown of what defines the 27555 area:

 

Geography and Location

  • Location: Micro is situated in the eastern part of Johnston County, nestled right between the towns of Kenly and Selma.
  • Transportation Corridors: The town sits directly along US Highway 301, giving residents easy access to local travel routes. It is also located near Interstate 95, making regional travel highly accessible.
  • Size: True to its name, Micro is incredibly small, encompassing less than half a square mile of land.

 

Demographics and Housing

  • Population: Micro is the least-populated incorporated community in Johnston County, with a population hovering right around 450 to 500 residents.
  • Housing Market: The real estate market here is very small and relatively affordable compared to the larger Triangle suburbs. Recent estimates place the median home value around $170,000.
  • Income: The median household income for the 27555 zip code is roughly $44,500.

 

History and Government

  • Railroad Origins: Like many towns in the area, Micro was settled around 1890 alongside the "Short-Cut" rail line of the Wilmington and Weldon Railroad.
  • What's in a Name: The town was originally incorporated in 1899 under the name "Jerome," named after a local landowner. However, in 1905, the town changed its name to Micro to avoid postal and railroad confusion with another North Carolina community called Jerome (located in Bladen County).
  • Local Government: Despite its small size, Micro maintains its own independent municipal structure, led by a mayor and a town commission, and it even operates its own local police department.

 

Education

Students living in the 27555 zip code are served by the Johnston County Public School District.

 

Lifestyle and Attractions

  • 301 Endless Yard Sale: While Micro is generally a quiet residential community, it comes alive during the third weekend of June every year. The town is a major participant and stopping point for the famous 301 Endless Yard Sale, an event that stretches for over 100 miles along US 301 and draws thousands of antique hunters, bargain shoppers, and vendors to the area.
