Q&A for How to Write an Address on an Envelope

You don't need to write anything on the back (flap) side of the envelope. All information, including the address and return address, should go on the front of the envelope. If you'd like to be fancy, you can place a sticker over the bottom of the "flap" on the back of the envelope. This will give it an old-fashioned look.

First line: name of specific person and position, if known. Second line: name of university. Third line: street address or P.O. Box. Fourth line: city, state, and zip or post code.

Take as many lines as necessary to list the invitees. List all of them above the mailing address.

If you're trying to be formal, use the titles.

If you know the addressee prefers to receive mail at one address or the other, list that address ''below'' the other. When in doubt, write the address the same way the addressee writes his/her/their address in correspondence.

Include his/her rank, the name of the military facility and its mailing address.

If you have their last name, address them as Mr/Mrs/Ms. If you don't, address them as, To the residents of: and then write their address.

You could just write: Mrs.(last name). Since this only mentions her, it is addressed to her.

That works fine, or you could list each first name individually, such as "Laura, Bob, Ethan, and Elizabeth Smith."

You could write "Personal" or something like, "To be opened by the addressee only."

You may do either. They're both correct.

You should omit commas and periods when writing addresses on envelopes.

Write both of their names, like, "Mrs. Victoria Banks and Mr. Reynold Smith."

That would be the beginning of the address (at least in the USA). 1234 Nowhere Ln. would indicate house #1234, on Nowhere Lane.

Sure. Generally, the only reason you'd do that is to put the name of the foreign country you're sending the letter to. Anything more specific should be somewhere up higher.

"Dr." not Mrs. The person with a professional title is always listed first. For example, you would write: "Dr. Jane Smith and Mr. John Smith."

All addresses (forwarding or not) should be written this way: name on the first line; street address or P.O. Box on the second line; city, two-letter state abbreviation, and zip code on the third line. If you are handwriting the address, use all capital letters on all lines (for legibility).

Assuming it is a formal letter, address them exactly as you have shown above - "Dr. John Doe and Dr. Jane Smith".

Revs. John Doe and Jim Doe; optionally, you could list them individually, with the title before each of them: Rev. John Doe and Rev. Jim Doe.

When addressing to a "junior" or "senior" it is customary to write that element (or "Jr." or "Sr.") on the outer envelope.

First name, then last.

"John and Jane Smith," "Mr. and Mrs. John Smith," "Mr. and Mrs. Smith" or "The Smiths." If they don't have the same last name, "John Smith and Jane Brown." (In each case, you can list Jane first if you prefer).

Use her first name and married name, or you could write her first name, maiden name and married name.

Either use smaller lettering or continue the company name on an indented second line. In the latter case, put the rest of the address on the third and fourth lines. The Postal Service won't care about this, as long as the bottom two lines follow the standard form. (If you want to be slightly less formal, you could list just two names followed by "and Partners" on the first line.)
