Footnotes ...

<1>If you're interested in how the shape of Massachusetts' counties, including Suffolk, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>Population counts have been provided by the U.S. Census Bureau. For more detail, please visit our Census Page for Chelsea.
<3>The elevation is an estimate for the area around Chelsea - 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 617 code has been Overlayed with the 857 area code. New phone numbers in the Chelsea area will be assigned with one of these codes: 617 or 857. As a result, placing a call in the Chelsea 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 Chelsea). When looking for a ZIP Code, whether Chelsea or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
