Footnotes ...

<1>If you're interested in how the shape of South Carolina's counties, including Colleton, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>The elevation is an estimate for the area around Round O - it will be higher in some places and lower in others.
<3>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 843 code has been Overlayed with the 854 area code. New phone numbers in the Round O area will be assigned with one of these codes: 843 or 854. As a result, placing a call in the Round O area will require 10-digit dialing (where you enter both the area code and then the phone number).
<4>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 Round O). When looking for a ZIP Code, whether Round O or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
