Footnotes ...
| <1> | If you're interested in how the shape of Massachusetts' counties, including Barnstable, have changed over time, we recommend the Atlas of Historical County Boundaries. |
| <2> | The elevation is an estimate for the area around East Dennis - 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 508 code has been Overlayed with the 774 area code. New phone numbers in the East Dennis area will be assigned with one of these codes: 508 or 774. As a result, placing a call in the East Dennis 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 East Dennis). When looking for a ZIP Code, whether East Dennis or elsewhere, it's always best to check the website of the United States Postal Service (USPS). |
| <5> | An 'estimated' location is one where we have been given GPS coordinates, but are unable to verify the accuracy of those coordinates. That said, we have some confidence that we have placed the marker near the actual location. A typical reason for being unable to verify a location is that it might be on private property or maybe historic and gone without an obvious trace. |
| <6> | The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required. |
| <7> | If we found a location and have questions about the accuracy of our information, we will simply say that the marker is 'in the vicinity'. We are not confident about the location and the position of our marker is only a rough guide. If we have too many doubts about the location, we will not include it in our database. |
