| <1> | If you're interested in how the shape of Ohio's counties, including Union, have changed over time, we recommend the Atlas of Historical County Boundaries. |
| <2> | The pronunciation we've provided is our attempt to give a phonetic pronunciation for Irwin. While it might not be exactly right, hopefully it will be close. If we have it wrong or there's a better way to pronounce the name, please contact us through our Feedback Page. |
| <3> | The elevation is an estimate for the area around Irwin - it will be higher in some places and lower in others. |
| <4> | When there's a risk of an area code running out of phone numbers, an 'Overlay Area Code' is created that has the same geographic boundaries as the existing area code. In this case, the 740 code has been Overlayed with the 220 area code. New phone numbers in the Irwin area will be assigned with one of these codes: 740 or 220. As a result, placing a call in the Irwin area will require 10-digit dialing (where you enter both the area code and then the phone number). |
| <5> | ZIP Codes have been created by the United States Postal Service (USPS) as a way of grouping addresses to make delivery more efficient. The boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes. So keep in mind that any given ZIP Code is only 'loosely' associated with a community (such as Irwin). When looking for a ZIP Code, whether Irwin or elsewhere, it's always best to check the website of the United States Postal Service (USPS). |
| <6> | The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required. |
