One of you astute Editor’s Corner readers noticed some inconsistences within different articles containing state abbreviations and comma use. At JHA, we use the Chicago Manual of Style, so here is a brief excerpt on the topic and some additional information I’ve collected for inquiring minds.
From the CMOS: “When following the name of a city, the names of states, provinces, and territories are enclosed in commas, whether they are spelled out (as in running text) or abbreviated (as in tabular matter or lists). In an exception to the rule, no comma appears between the postal code [KC – The two-letter abbreviation.] and a zip code.”
Examples of using cities, states, and commas in running text:
· Chicago Manual of Style

· AP Stylebook
Her voyage will take her from Charlotte, N.C., to San Diego, Calif.
· Postal Address
