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, establish a new 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 identification number 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 San Quentin: 232465

GNIS ID for Marin County: 277285

GNIS ID for California: 1779778

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 San Quentin:

Place (Community) Code:	68336
State Code:	06 (California)
County Code:	041 (Marin 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:	06/68336
State/County Code:	06/041

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 California:	06		1779778
Marin County:	06/041		277285
San Quentin:	06/68336		232465

GPS Location - GNIS Coordinates ...

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 San Quentin, it is a point within San Quentin 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 San Quentin, the GNIS GPS location is given as:

Lat:   37° 56' 28"   (or 37.94°)

Lon:   -122° 29' 5"   (or -122.48°)  

Regional Codes ...

For statistical purposes, the US Census Bureau has divided the country into four Regions. San Quentin is located in Region #4 (the West Region).

In turn, the US Census Bureau has further divided each Region into Divisions. San Quentin is located in Division #9 (the Pacific Division).

The Office of Management and Budget (OMB) has created ten Federal Regions. San Quentin is located in Region IX (Region 9).

The Federal Emergency Management Agency (FEMA) has created ten Management Regions. San Quentin is located in Region IX (Region 9).

ZIP Codes ...

While some people have used ZIP codes to identify a community, the ZIP codes were actually created to make mail delivery more efficient by grouping addresses together. Although a ZIP Code doesn't specifically identify a community like San Quentin, they do identify addresses that are in (or near) the community. 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.
