Miscellaneous Information

Various Identification Codes ...

GNIS Codes ...

The U.S. Board on Geographic Names (BGN) was created to address the problems caused by spelling and naming variations. The BGN will usually recognize an existing name or, when necessary, chose a name for a geographic feature (such as a mountain, lake, river, stream, city, town, village, dam, bridge, etc).

The BGN names are kept in a database called the Geographic Names Information System (GNIS) and it is the official Federal repository. The GNIS is operated and maintained by the U.S. Geological Survey (USGS).

A unique and permanent numeric identifier has been assigned for each name in the GNIS database. These names and identifiers are definitive and it is intended that they are to be used by all departments of the Federal Government:

GNIS ID for Woodstock: 2397372

GNIS ID for McHenry County: 1784815

GNIS ID for Illinois: 1779784

FIPS Codes ...

In a past effort, various federal agencies created a set of codes with a purpose similar to the GNIS codes. These codes are called the Federal Information Processing Standard (or the FIPS 55 codes). Although they are still used by some organizations, the FIPS codes are obsolete and will ultimately be replaced by the GNIS codes.

The following FIPS codes apply to Woodstock:

Place (Community) Code:	83349
State Code:	17 (Illinois)
County Code:	111 (McHenry County)

Since the Place and County FIPS codes are not unique and can be repeated in other States, it's necessary to combine the State code with the Place and County FIPS codes to uniquely identify them - for example:

State/Place Code:	17/83349
State/County Code:	17/111

As already mentioned, the FIPS codes are to be replaced by the GNIS codes. The following reflect those changes:

	FIPS Code	translates to	GNIS Code
State of Illinois:	17		1779784
McHenry County:	17/111		1784815
Woodstock:	17/83349		2397372

GPS Location - GNIS vs Census ...

An important aspect of the GNIS code is that it assigns a GPS location (the latitude/longitude) to the geographic feature. This location is simply a point on the map and does not represent the size or shape of the feature. In the case of Woodstock, it is a point within Woodstock that might be a post office, the city hall or simply an intersection - the point should really be considered arbitrary and only indicating a general location.

For Woodstock, the GNIS GPS location is given as:

Lat:   42° 18' 38"   (or 42.31°)

Lon:   -88° 26' 5"   (or -88.43°)  

Determined by its statistical needs, the Census Bureau has defined a sampling area for Woodstock - this area also contains a map point. As with the GNIS code, the location of the Census point should be considered as being arbitrary within the sampling area.

For Woodstock, the Census 2010 GPS location is given as:

Lat:   42° 18' 36"   (or 42.31°)

Lon:   -88° 26' 8"   (or -88.44°)  

The map point defined by the Census Bureau lies 232.2 feet to the southwest<1> of the point given by the GNIS (see above).

You might note that the GPS location given for the 2010 Census is different than the location that was specified by the 2000 Census:

Lat:   42° 19' 3"   (or 42.32°)

Lon:   -88° 26' 46"   (or -88.45°)  

The GPS location given for the 2000 Census lies 3,904 feet to the northwest<2> of the point given by the 2010 Census.

Regional Codes ...

For statistical purposes, the US Census Bureau has divided the country into four Regions. Woodstock is located in Region #2 (the Midwest Region).

In turn, the US Census Bureau has further divided each Region into Divisions. Woodstock is located in Division #3 (the East North-Central Division).

The Office of Management and Budget (OMB) has created ten Federal Regions. Woodstock is located in Region V (Region 5).

The Federal Emergency Management Agency (FEMA) has created ten Management Regions. Woodstock is located in Region V (Region 5).

ZIP Codes ...

While some people have used a ZIP code to identify a community, the purpose of the ZIP code was to make mail delivery more efficient by grouping addresses together. Although the ZIP Code doesn't specifically identify a city like Woodstock, it does identify addresses that are in (or near) Woodstock. It's important to remember that the boundaries of a ZIP Code are defined by the needs of the USPS and can be changed, re-assigned or overlapped with other ZIP Codes.

The ZIP code for Woodstock: 60098<3>
