| <1> | The pronunciation we've provided is our attempt to give a phonetic pronunciation for Belvidere. While it might not be exactly right, hopefully it will be close. If we have it wrong or there's a better way to pronounce the name, please contact us through our Feedback Page. |
| <2> | Area code (779) is an overlay for area code (815). |
| <3> | 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 Belvidere). When looking for a ZIP Code, whether Belvidere or elsewhere, it's always best to check the website of the United States Postal Service (USPS). |
| <4> | The elevation is an estimate for the area around Belvidere - it will be higher in some places and lower in others. |
| <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 Belvidere. 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. |
