Postal abbreviations

For the place of publication, give the city and state for U.S. cities or the city and country for all others. The country or state is not needed if the city is considered a major city in the world and could not be confused easily with other cities of the same name (e.g., London, Paris, New York, and Rome). Use the two-letter postal abbreviations (listed in Chapter 10) for states. Spell out names of countries unless they have standard abbreviations, such as U.K. for United Kingdom. 

State - Identifies the state where the principal place of business is located. Two-letter postal abbreviation for the state. 

The following state abbreviations are recognized by the U. S. Postal Service. You can use them in your business letters and on the envelopes.
