<3>Population counts have been provided by the U.S. Census Bureau. For more detail, please visit our Census Page for Ohlman.
<4>The elevation is an estimate for the area around Ohlman - it will be higher in some places and lower in others.
<5>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 217 code has been Overlayed with the 447 area code. New phone numbers in the Ohlman area will be assigned with one of these codes: 217 or 447. As a result, placing a call in the Ohlman area will require 10-digit dialing (where you enter both the area code and then the phone number).
<6>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 village (such as Ohlman). When looking for a ZIP Code, whether Ohlman or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
