When writing cities and states, what is the proper way?
The mail was forwarded to 123 ABC Street, Louisville, Kentucky 40245, over a week ago.
(CMoS 6:48) Commas are used to set off a place of residence immediately following a person’s name unless the place is essential to the meaning of the sentence or is considered part of the person’s name.
Em Petrova, from Pennsylvania, writes smut.
NO COMMAS: The Pitts of New York City are unrelated to Brad Pitt.
Hope this helps you when writing places! Thanks for reading.
