Miscellaneous Information for Irwin ...

The Federal government has assigned various identifying codes to each community, county and state. At one time or another, the US Census Bureau has used one (or more) of the following identifiers when referring to either Union County or the community of Irwin:

• The GNIS Codes ...
  • The current system of identification is called the Geographic Names Information System (GNIS). The following GNIS codes relate to Irwin:
  • GNIS ID for Irwin: 1064891
  • GNIS ID for Union County: 1074091
  • GNIS ID for State of Ohio: 1085497

  • An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):
  • State Code: 39 (Ohio)
  • County Code: 159 (Union County)
  • Place Code: 37520 (Irwin)
  • State & County Code: 39/159 (Ohio / Union County)

• Misc. Census Codes ...
  • Irwin is located in Census Region #2 (the Midwest Region) and Division #3 (the East North-Central Division).

• The US Postal Service ZIP Code ...
  • While some people have used a ZIP code to identify a community, the purpose of the ZIP code was to make mail delivery more efficient by grouping addresses together. Although the ZIP Code doesn't specifically identify a community like Irwin, it does identify addresses that are in (or near) Irwin. It's important to remember that the boundaries of a ZIP Code can be changed, re-assigned or overlapped with other ZIP Codes.
  • The ZIP code for Irwin:43029<3>

• Census ZCTA Codes ...
  • The US Census Bureau created statistical entities that they call ZIP Code Tabulation Areas (ZCTAs) and these ZCTAs are frequently confused with the ZIP codes that come from the US Postal Service (USPS).
  • ZCTAs were first created for the 2000 Census and at that time, they were based upon the USPS ZIP codes. While largely covering the same areas, the boundaries of a ZCTA do not necessarily match the boundaries of a postal ZIP code with the same number. For example, while a postal ZIP code can cross a county or state line, a Census ZCTA can not. They should be treated as separate entities with no correlation between them.
