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 code 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 Dayton: 856226

GNIS ID for Lyon County: 858645

GNIS ID for Nevada: 1779793

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 Dayton:

Place (Community) Code:	17500
State Code:	32 (Nevada)
County Code:	019 (Lyon 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:	32/17500
State/County Code:	32/019

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 Nevada:	32		1779793
Lyon County:	32/019		858645
Dayton:	32/17500		856226

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

Lat: 39° 14' 13" (or 39.24°)

Lon: -119° 35' 34" (or -119.59°)

Regional Codes ...

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

In turn, the US Census Bureau has further divided each Region into Divisions. Dayton is located in Division #8 (the Mountain Division).

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

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

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 community like Dayton, it does identify addresses that are in (or near) Dayton. 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 Dayton: 89403<1>
