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 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 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 South Hadley: 618208

GNIS ID for Hampshire County: 606934

GNIS ID for Massachusetts: 606926

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 South Hadley:

Place (Community) Code:  64110
State Code:  25 (Massachusetts)
County Code:  015 (Hampshire 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:  25/64110
State/County Code:  25/015

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 Massachusetts:    25   606926
Hampshire County:    25/015   606934
South Hadley:    25/64110   618208

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

Lat:   42° 15' 30"   (or 42.26°)

Lon:   -72° 34' 28"   (or -72.57°)   [Map]

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

Lat:   42° 15' 22"   (or 42.26°)

Lon:   -72° 34' 50"   (or -72.58°)   [Map]

The map point defined by the Census Bureau lies 1,843 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° 14' 5"   (or 42.23°)

Lon:   -72° 34' 56"   (or -72.58°)   [Map]

The GPS location given for the 2000 Census lies 7,835 feet to the south<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. South Hadley is located in Region #1 (the Northeast Region).

In turn, the US Census Bureau has further divided each Region into Divisions. South Hadley is located in Division #1 (the New England Division).

The Office of Management and Budget (OMB) has created ten Federal Regions. South Hadley is located in Region I (Region 1).

The Federal Emergency Management Agency (FEMA) has created ten Management Regions. South Hadley is located in Region I (Region 1).

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 South Hadley, it does identify addresses that are in (or near) South Hadley. 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 South Hadley: 01075<3>
