<3>The elevation is an estimate for the area around Morro Bay - it will be higher in some places and lower in others.
<4>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 805 code has been Overlayed with the 820 area code. New phone numbers in the Morro Bay area will be assigned with one of these codes: 805 or 820. As a result, placing a call in the Morro Bay area will require 10-digit dialing (where you enter both the area code and then the phone number).
<5>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 Morro Bay). When looking for a ZIP Code, whether Morro Bay or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
