The following are the two-letter state codes used in the USA. They were standardized by the USPS, and are also used in domain names, such as washington.dc.us and miami.fl.us .
Their use should be accompanied by a plain designation of "United States" in documents with an international circulation, since many are not readily recognised by themselves outside the U.S. Care must especially be taken not to be ambiguous about whether "Georgia" means the state (GA) or the country (GE).
Similar state codes may also be confusing even to some Americans, as MA (Massachusetts) is sometimes absent-mindedly used for Maine (ME), and MI (Michigan) mistaken for Missouri (MO), Mississippi (MS), or even Minnesota (MN). For this reason, correct ZIP codes should always be used.
