Should you use a comma after state code before zip code?

Answer 1

No, you do not put a comma between the state and zip code. You do, however, put a comma between the city and state. For example: Atlanta, Georgia Salisbury, Maryland 21801 -----------------------------------------------------------------------------------------------

Follow the Zip Code with a comma if the address is used in a sentence:

"Within a sentence, use a comma after the name of the addressee (if included), the street name, the city name, and the state name unless it is followed by a ZIP+4 Code. Use a comma after--but not before--a ZIP or Zip+4 code. Their stay in Niagara Falls, New York, was a very enjoyable one. Please write to Ms. Audrey M. Greene, 2244 Lakeside Road, Rockford, Illinois 61102, as soon as possible."

Answer 2

No you do not. You put a comma in between state and city though.
