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 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 Chain Bridge: 1212004 GNIS ID for Northampton County: 1209185 GNIS ID for Pennsylvania: 1779798 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).

The Office of Management and Budget (OMB) has created ten Federal Regions. Chain Bridge would have been located in Region III (Region 3). The Federal Emergency Management Agency (FEMA) has created ten Management Regions. Chain Bridge would have been located in Region III (Region 3). Referenced GNIS Records ...Referenced FIPS Records ...FIPS Code: 42/12480 (Place Name: Chain Bridge) County: Bucks (FIPS State/County: 42/017) Class: U8 Identifies a populated place (in this case, Chain Bridge) located wholly or substantially outside the boundaries of an incorporated place or CDP (Census Designated Place) but whose name has not been verified as authoritative by the U.S. Geological Survey (USGS).
