Address on envelope to a doctor: Dr. John Doe is the general form.
Dr. & Mrs. John Smith
Drs. _______ and ________ Smith
The proper way to address an envelope for a Ph.D. is "Dr. [Full Name]" followed by their address.
When addressing a business envelope where the husband is Mr. and the wife is Dr., the proper way to format the names is to list the titles in alphabetical order. Therefore, you would address the envelope as "Dr. and Mr. [Last Name]." For example: "Dr. and Mr. Smith." This shows respect for both titles.
The correct way to address the envelope is: Mr. John Doe & Dr. Jane Doe.
The envelope should read: Mr. John Doe & Dr. Jane Doe. If you don't know her first name then put: Mr. & Dr. John Doe.
When addressing an envelope to the wife of a doctor who is not a doctor herself then and he is Dr. John Doe, then address the envelope to her as Mrs. John Doe or Ms. (Mrs.) Jane Doe.
Dr. (First name)(Last name) OR Dr. (Last name) For example: Dr. Lily Copper / Dr. Cooper
That would be: "Dr. John and Mrs. Jane Whomsoever".
A PhD is a doctor. You address a letter to him Dr. John Smith. If he is married you address it Dr. John and Jane Smith. If she has the PhD, you address it John and Dr Sue Smith. If both have their PhD's you address it Drs, Henry and Jane Smith.
