Footnotes ...

<1>	If you're interested in how the shape of Oklahoma's counties, including Delaware, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>	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 918 code has been Overlayed with the 539 area code. New phone numbers in the Steeley area will be assigned with one of these codes: 918 or 539. As a result, placing a call in the Steeley area will require 10-digit dialing (where you enter both the area code and then the phone number).
