== History ==
As early as October 1874, the [[United States Postal Service|United States Post Office]] recognized common abbreviations for states and territories. However, they only accepted these abbreviations because of their popularity, preferring that patrons spell names out in full to avoid confusion.<ref name="USPS History">[http://about.usps.com/who-we-are/postal-history/state-abbreviations.pdf USPS Postal History: State Abbreviations] Accessed November 7, 2011.</ref>

The traditional abbreviations for U.S. states and territories, widely used in mailing addresses prior to the introduction of two-letter U.S. postal abbreviations, are still commonly used for other purposes (such as [[legal citation]]), and are still recognized (though discouraged) by the Postal Service.<ref>USPS Postal News, "It's Okay to Say 'I Don’t Know,' So Long As You Find Out!" January 9, 2009 [http://www.usps.com/communications/newsroom/localnews/fl/2009/fl_2009_0109.htm]</ref>

Modern two-letter abbreviated codes for the states and territories originated when the Post Office introduced [[ZIP code]]s in 1963. The purpose was to make room for ZIP codes in the address, rather than to standardize state abbreviations ''per se''.<ref name="USPS History"/>

Since 1963, only one state abbreviation has changed. Originally [[Nebraska]] was “NB”; but, in November 1969, the Post Office changed it to “NE” to avoid confusion with [[New Brunswick]] in Canada.<ref name="USPS History"/>

The two-letter postal abbreviation system is complicated by the fact that eight state names begin with ''M'' and to avoid duplication, some abbreviations are not intuitive.

{{Anchor|GPO}}
Prior to 1987, when the U.S. [[Secretary of Commerce]] approved the two-letter codes for use in government documents,<ref>Federal Information Processing Standards Publication 5-2, May 28, 1987
[http://www.itl.nist.gov/fipspubs/fip5-2.htm] Accessed April 21, 2009.</ref> the [[United States Government Printing Office]] ('''GPO''') suggested its own set of abbreviations, with some states left unabbreviated. Today, the GPO supports United States Postal Service standard.<ref>U.S. Government Printing Office Style Manual, 30th Edition [http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=2008_style_manual&docid=f:chapter9.pdf] Accessed April 21, 2009.</ref>

==ISO standard 3166==
{{main|ISO 3166-2:US}}

==ANSI standard INCITS 38:2009==
The [[American National Standards Institute]] (ANSI) established alphabetic and numeric codes for each state and outlying areas in [[INCITS 38|ANSI standard INCITS 38:2009]]. ANSI standard INCITS 38:2009 replaced the [[Federal Information Processing Standard]] (FIPS) standards [[FIPS 5-2]], [[FIPS 6-4]], and [[FIPS 10-4]]. The ANSI alphabetic state code is the same as the USPS state code except for U.S. Minor Outlying Islands, which have a ANSI code “UM” but no USPS code—and U.S. Military Mail locations, which have USPS codes (“AA”, “AE”, “AP”) but no ANSI code.

The [[United States Postal Service]] has established a set of uppercase abbreviations to help process mail with [[optical character recognition]] and other automated equipment.<ref name="uspspub28">United States Postal Service [http://pe.usps.gov/text/pub28/welcome.htm Publication 28 - Postal Addressing Standards.] Accessed February 4, 2007.</ref> There are also official USPS abbreviations for other parts of the address, such as street designators (street, avenue, road, etc.).

These postal abbreviations are distinguished from [[#Traditional abbreviations|traditional abbreviations]] such as Calif., Fla., or Tex. The [[Associated Press]] [[AP Stylebook|Stylebook]] states that in contexts other than mailing addresses, the traditional state abbreviations should be used.<ref name="Style Manuals on State Abbreviations">[http://www.nyu.edu/classes/copyXediting/STABBREV.html State Abbreviations]</ref> However, [[the Chicago Manual of Style]] now recommends use of the uppercase two-letter abbreviations, with the traditional forms as an option.<ref>[http://www.chicagomanualofstyle.org/about15_rules.html Major Rule Changes in The Chicago Manual of Style, Fifteenth Edition] Accessed May 23, 2009</ref>

The postal abbreviation is the same as [[ISO 3166-2]] subdivision code for all fifty states.

These codes do not overlap with the thirteen [[Canadian subnational postal abbreviations]]. The code for Nebraska changed from NB to NE in November 1969 to avoid a conflict with New Brunswick.<ref name="USPS History"/>

==USCG==
The [[United States Coast Guard|U.S. Coast Guard]] uses a set of two-letter prefixes for vessel numbers;<ref>33 C.F.R. Pt. 173, App. A</ref> 39 states and the District of Columbia have the same USPS and USCG abbreviations. USCG prefixes have also been established for five outlying territories; all are the same as the USPS abbreviations except the Mariana Islands. The small table below shows the 12 cases where USPS and USCG abbreviations are different.

== Current use of traditional abbreviations ==

The [[AP Stylebook|Associated Press Stylebook]], the usage guide for most United States newspapers, counsels the use of abbreviations for most state names, when appended to a city name (for example, “Santa Ana, Calif.”). AP suggests spelling out “Alaska”, “Hawaii”, and all state names with five or fewer letters; and, unlike the old GPO recommendations, AP suggests spelling out the names of all non-state territories, with the exception of the District of Columbia (D.C.). [[Legal citation]] manuals, such as ''[[Bluebook|The Bluebook]]'' and ''[[ALWD Citation Manual|The ALWD Citation Manual]]'', typically use these "traditional abbreviations" as well.
