Footnotes ...

<1>If you're interested in how the shape of Maryland's counties, including Wicomico, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>A portmanteau (such as Delmar) is the combination or contraction of two (or more) words, their sound and the meaning of those words to create a new word. For example, camera and recorder becomes camcorder.
<3>Population counts have been provided by the U.S. Census Bureau. For more detail, please visit our Census Page for Delmar.
<4>The elevation is an estimate for the area around Delmar - 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 410 code has been Overlayed with one of the following codes: 443 or 667. New phone numbers in the Delmar area will be assigned with one of these codes: 410, 443 or 667. As a result, placing a call in the Delmar 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 town (such as Delmar). When looking for a ZIP Code, whether Delmar or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
<7>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.
