Federal Information Processing Standards Publications (FIPS
PUBS) are issued by the National Institute of Standards and Technology
(NIST) after approval by the Secretary of Commerce pursuant to
Section 111 (d) of the Federal Property and Administrative Services
Act of 1949 as amended by the Computer Security Act of 1987, Public
Law 100-235.
- Name of Standard. Counties and Equivalent Entities
of the United States, Its Possessions, and Associated Areas.
- Category of Standard. Federal General Data Standard,
Representations and Codes.
- Explanation.
- a. Federal Information Processing Standard (FIPS) 6-4 provides
the names and codes that represent the counties and other entities
treated as equivalent legal and/or statistical subdivisions of
the 50 States, the District of Columbia, and the possessions
and freely associated areas of the United States. Counties are
considered to be the "first-order subdivisions" of
each State and statistically equivalent entity, regardless of
their local designations (county, parish, borough, etc.). Thus,
the following entities are considered to be equivalent to counties
for legal and/or statistical purposes: The parishes of Louisiana;
the boroughs and census areas of Alaska; the District of Columbia;
the independent cities of Maryland, Missouri, Nevada, and Virginia;
that part of Yellowstone National Park in Montana; and various
entities in the possessions and associated areas.
- b. FIPS 6-4 contains minor editorial changes from the text
of FIPS 6-3. It also incorporates technical changes that the
NIST issued as Change Notices to FIPS 6-3. FIPS 6-4 supersedes
FIPS 6-3 in its entirety.
- Approving Authority. The Secretary of Commerce.
- Maintenance Agency. U.S. Department of Commerce, Bureau
of the Census, Geography Division.
Questions concerning the list of entities and their assigned
codes are to be addressed to the Maintenance Agency: Office of
the Chief, Geography Division, Bureau of the Census, Washington,
DC 20233. Users of this standard who need to be notified of changes
that occur prior to the next publication of the standard must
complete the Change Request Form provided in this publication
and send it to: Standards Processing Coordinator (ADP), National
Computer Systems Laboratory, National Institute of Standards
and Technology, Gaithersburg, MD 20899. The NIST will issue Change
Notices on an as-needed basis.

improve the utilization of data resources of the Federal Government
and to avoid unnecessary duplication and incompatibilities in
the collection, processing, and dissemination of data.
- Applicability. This standard is prescribed for the
collection, processing, and interchange of coded data by Federal
agencies, and whenever requirements for such data are imposed
by a Federal agency on industry, State or local governments,
or the public. Use within agency data systems is encouraged when
such use contributes to operational benefits, efficiency, and/or
economy.

Specifications for
COUNTIES AND EQUIVALENT ENTITIES OF THE UNITED STATES,
ITS POSSESSIONS, AND ASSOCIATED AREAS
- Name of Standard. Counties and Equivalent Entities
of the United States, Its Possessions, and Associated Areas.
- Category of Standard. Federal General Data Standard,
Representations and Codes.
- Explanation. This standard provides the names and
codes that represent the counties and other entities treated
as the equivalents of counties for legal and/or statistical purposes
in the 50 States, the District of Columbia, and the possessions
(American Samoa, Guam, Northern Mariana Islands, Palau, Puerto
Rico, and Virgin Islands of the United States) and freely associated
areas (Federated States of Micronesia and Marshall Islands) of
the United States. Palau is the last remaining component of the
Trust Territory of the Pacific Islands (TTPI); for presentation
purposes, Palau, rather than the TTPI, is treated as the State-equivalent
entity.
The term "counties" refers to the "first-order
subdivisions of each State and statistically equivalent entity,
regardless of the local terminology (county, parish, borough,
etc.). First-order subdivisions of the States include the parishes
of Louisiana; the boroughs and census areas of Alaska; the independent
cities of Maryland, Missouri, Nevada, and Virginia; and the portion
of Yellowstone National Park in Montana. In the possessions,
entities regarded as first-order subdivisions are as follows:
American Samoa: districts and islands (the areas legally designated
as "counties" in American Samoa are second-order subdivisions);
Northern Mariana Islands: municipalities; Palau: states; Puerto
Rico: municipios; Virgin Islands: islands (comprising the three
major islands). The District of Columbia and Guam have no first-
order subdivisions, and therefore these same areas serve as the
first-order subdivisions. First-order subdivisions of Federated
States of Micronesia are states; of Marshall Islands, municipalities.
- Specifications. The succeeding pages of this standard
provide a list, by State, of the names and codes of the counties
and equivalent entities. The States and the District of Columbia
are listed in alphabetical sequence; the possessions are listed
alphabetically in Appendix A, and the associated areas in Appendix
B. Within each State and statistically equivalent entity, the
counties or equivalent entities are listed in alphabetical sequence
except for independent cities, which comprise a separate alphabetical
and numeric (code) sequence following the list of counties in
their respective States. This list of first-order subdivisions
provides complete coverage of the United States and its possessions
and associated areas.
- Qualifications. County codes are assigned uniquely
within each State and equivalent entity. In other words, counties
in different States will have the same code; for example, code
001 is assigned to both Autauga County, Alabama and Apache County,
Arizona. Accordingly, in data systems concerned with the identification
of counties in more than one State, the county code must be used
in conjunction with Federal Information Processing Standard 5,Codes
for the Identification of the States, the District of Columbia
and the Outlying Areas of the United States, and Associated Areas.
Autauga County, Alabama would be represented as AL001 and Apache
County, Arizona would be represented as AZ001 when the State
alphabetic codes are used; and as 01001 and 04001, respectively,
when the State numeric codes are used. The form of representation
(State alphabetic or numeric code) is to be identified in format
descriptions for those data systems that use the representations
described in this standard.
- Special Information.
- a.Changes in this revision of the standard are noted
by a "*"symbol following the county code if the code
is new. or the county name if it is different from that reported
in FIPS PUB 6-3. All new and deleted areas are explained
by footnotes. Minor name revisions are not explained.
- b. This standard does not apply to the codes established
by the U.S. Department of Agriculture to meet the unique program
requirements of Public Law 85-278 (71 Stat. 601) and the Soil
Conservation and Domestic Allotment Act (16 U.S.C. 590H). For
information on these requirements and the associated codes, contact
the Office of Operations, U.S. Department of Agriculture, Washington,

New Borough in Alaska
Yakutat Borough, county-equivalent entity, was established by
the State of Alaska effective September 22, 1992.
- The new borough removes territory from the Skagway- Yakutat-Angoon
Census Area (also a county-equivalent in Alaska; FIPS county
code 231). With the loss of Yakutat, that census area is renamed
Skagway-Hoonah-Angoon (FIPS county code 232).

PUBLICATION TITLE
Counties and Equivalent Entities of the United States,
Its Possessions, and Associated Areas
The independent city (county-equivalent) of South Boston, Virginia,
is reverting to town status, effective midnight, June 30, 1995.
South Boston will then be an incorporated place within Halifax
County, rather than a separate county-equivalent surrounded by
Halifax Count.
This action will reduce the number of Virginia independent cities
to 40, and the number of United States counties and equivalent
areas to 3,142. The action reduces the total number of independent
cities in the United States to 43.
The FIPS county code of 780 for South Boston, Virginia, is
deleted. The FIPS 55 class code will change from C7 to C1. The
census place code of 1135 and FIPS 55 code of 73712 are unaffected.
The FIPS county code of 083 for Halifax County remains unchanged.
