<2>The elevation is an estimate for the area around Big Oak Flat - 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 209 code has been Overlayed with the 350 area code. New phone numbers in the Big Oak Flat area will be assigned with one of these codes: 209 or 350. As a result, placing a call in the Big Oak Flat 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 Big Oak Flat). When looking for a ZIP Code, whether Big Oak Flat or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
