| <4> | The elevation is an estimate for the area around El Dorado - 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 870 code has been Overlayed with the 327 area code. New phone numbers in the El Dorado area will be assigned with one of these codes: 870 or 327. As a result, placing a call in the El Dorado 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 El Dorado). When looking for a ZIP Code, whether El Dorado or elsewhere, it's always best to check the website of the United States Postal Service (USPS). Our list of ZIP Codes for El Dorado includes: 71730 & 71731. |
