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 Aberdeen Proving Ground:

Place (Community) Code:	00175
State Code:	24 (Maryland)
County Code:	025 (Harford 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:	24/00175
State/County Code:	24/025

Regional Codes ...

For statistical purposes, the US Census Bureau has divided the country into four Regions. Aberdeen Proving Ground is located in Region #3 (the South Region).

In turn, the US Census Bureau has further divided each Region into Divisions. Aberdeen Proving Ground is located in Division #5 (the South Atlantic Division).

The Office of Management and Budget (OMB) has created ten Federal Regions. Aberdeen Proving Ground is located in Region III (Region 3).

The Federal Emergency Management Agency (FEMA) has created ten Management Regions. Aberdeen Proving Ground is located in Region III (Region 3).

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 Aberdeen Proving Ground, it does identify addresses that are in (or near) Aberdeen Proving Ground. 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 Aberdeen Proving Ground: 21005<1>
