<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 815 code has been Overlayed with the 779 area code. New phone numbers in the De Kalb area will be assigned with one of these codes: 815 or 779. As a result, placing a call in the De Kalb 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 city (such as De Kalb). When looking for a ZIP Code, whether De Kalb or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
