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 Pompeys Pillar). When looking for a ZIP Code, whether Pompeys Pillar or elsewhere, it's always best to check the website of the United States Postal Service (USPS).
<2>The elevation is an estimate for the area around Pompeys Pillar - it will be higher in some places and lower in others.
<3>Longitude & latitude values may not be the geographic center of Pompeys Pillar, rather it may be a prominent intersection or the center of population, etc. It will vary depending on the source.
<4>Name of the USGS 7.5 Minute topographic map which includes Pompeys Pillar.
<5>Every year, the US Census Bureau creates a population estimate for the preceeding year. Keep in mind that this value is an estimate and not an actual count. The most recent Census estimate is for the year 2019.
<6>The area value has been supplied by the US Census Bureau and it can be different than the geographic boundaries of Pompeys Pillar. The value given by the Census Bureau reflects their statistical (or sampling) requirements. For example, if there is a cluster of people living just outside of the community's official boundary, the Census-defined area might be expanded to include that group.
