When abbreviating the name of a state in a sentence or designated location, use proper abbreviation including periods as opposed to postal abbreviation (in parentheses). Use the postal abbreviation only when the state is part of a mailing address, and followed by a zip code.
The following states are not abbreviated in print. Their postal abbreviations are in parenthesis:
When the name of a state is used alone in a sentence, spell out the name in its entirety.Johnson & Wales University’s first and oldest campus is in Rhode Island. The university also has campuses in North Miami, Fla., Denver, Colo., and Charlotte, N.C. The university’s official mailing address is 8 Abbott Park Place, Providence, RI 02903.
When writing out a city and state, always put the correct abbreviation of the state following a city. Do not follow the AP dateline rule of using certain cities alone (not followed by the state they are in).The student, from Atlanta, Ga., transferred to the North Miami Campus from Northeastern University in Boston, Mass.
See the Campus section for more city and state information.
