<1>If you're interested in how the shape of Maryland's counties, including Baltimore, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>The elevation is an estimate for the area around Long Green - 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 410 code has been Overlayed with one of the following codes: 443 or 667. New phone numbers in the Long Green area will be assigned with one of these codes: 410, 443 or 667. As a result, placing a call in the Long Green 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 Long Green). When looking for a ZIP Code, whether Long Green or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
