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 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 Ontario: 2411323

GNIS ID for San Bernardino County: 277300

GNIS ID for California: 1779778

FIPS Codes ...

In a past effort, various federal agencies worked together to create 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 Ontario:

Place (Community) Code:	53896
State Code:	06 (California)
County Code:	071 (San Bernardino 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:	06/53896
State/County Code:	06/071

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
San Bernardino County:	06/071		277300
Ontario:	06/53896		2411323

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

Lat:   34° 2' 20"   (or 34.04°)

Lon:   -117° 36' 23"   (or -117.61°)  

Determined by its statistical needs, the Census Bureau has defined a sampling area for Ontario - 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 Ontario, the Census 2010 GPS location is given as:

Lat:   34° 2' 22"   (or 34.04°)

Lon:   -117° 36' 31"   (or -117.61°)  

The map point defined by the Census Bureau lies 717 feet to the west<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:   34° 3' 10"   (or 34.05°)

Lon:   -117° 37' 40"   (or -117.63°)  

The GPS location given for the 2000 Census lies 7,531 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. Ontario is located in Region #4 (the West Region).

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

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

The Federal Emergency Management Agency (FEMA) has created ten Management Regions. Ontario 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 city like Ontario, they do identify addresses that are in (or near) the city. 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.

Our list of ZIP codes for Ontario :

91758, 91761, 91764 & 91798.<3>

Referenced GNIS Records ...

GNIS ID #1652764   (Name of Record: Ontario)

Class: populated place

A place or area having clustered or scattered buildings and a permanent population (such as a city, settlement, town or village). The boundaries may or may not coincide with the perceived population.

A 'populated place' record may have a corresponding 'census' or 'civil' record. The information contained in the 'populated place' record applies only to the class and should not be confused with either the 'census' and 'civil' classes.

County: San Bernardino

Map Name: Ontario

Lat: 34.0633443       Lon: -117.6508876  

Elev: 306 ft.

GNIS ID #2411323   (Name of Record: City of Ontario)

Class: civil

A political division formed for administrative purposes (such as a borough, county, incorporated place, parish, town or township).

A 'civil' record may have a corresponding 'census' or 'populated place' record. The information contained in the 'civil' record applies only to the class and should not be confused with either the 'census' and 'populated place' classes.

County: San Bernardino

Map Name: Guasti

Lat: 34.0391007       Lon: -117.60645

Referenced FIPS Records ...
