How to Address Wedding Invitations

Addressing the envelopes is where wedding etiquette gets specific. Here is exactly how to write each guest's name — married couples, unmarried partners, families, doctors, single guests and plus-ones — plus how the inner and outer envelopes differ.

The short answer: On the outer envelope, write the guest's full formal name and address; on the optional inner envelope, write the more relaxed form (titles and last names, or first names for close family). Spell out titles and "and" who is actually invited — the envelope is how guests learn whether children and plus-ones are included.

Outer vs inner envelope

Traditional formal invitations use two envelopes, and each has a job:

Outer envelope — carries the mailing address and the guests' full, formal names (with titles).
Inner envelope — un-gummed, holds the invitation, and lists exactly who is invited in a slightly less formal way. This is where you make it clear whether children or a guest are included.

Most modern, casual weddings skip the inner envelope and put everything on a single outer envelope — that's perfectly fine. The key is that the names you write tell guests who is invited.

Addressing cheat-sheet

Guest	Outer envelope	Inner envelope
Married couple (same last name)	Mr. and Mrs. James Bennett	Mr. and Mrs. Bennett
Married couple (different last names)	Ms. Olivia Carter and Mr. James Bennett	Ms. Carter and Mr. Bennett
Married couple, both doctors	The Doctors Bennett	The Doctors Bennett
One doctor (woman)	Dr. Olivia Bennett and Mr. James Bennett	Dr. Bennett and Mr. Bennett
Unmarried couple living together	Ms. Olivia Carter and Mr. James Bennett (two lines, alphabetical)	Ms. Carter and Mr. Bennett
Family with young children	Mr. and Mrs. James Bennett	Mr. and Mrs. Bennett Emma and Liam
Single guest	Ms. Sophia Reed	Ms. Reed
Single guest with a plus-one	Ms. Sophia Reed	Ms. Reed and Guest

The rules behind the table

Spell out titles and the word "and." Use Mr., Mrs., Ms., Dr. — and write "and," not an ampersand, on formal envelopes.
Children signal inclusion by being named. If children's names appear on the inner envelope, they're invited; if only the parents are listed, they're not. This is the polite way to convey an adults-only wedding.
Plus-ones go on the inner envelope as "and Guest." If you write only the named guest, no plus-one is implied.
Alphabetise unmarried couples when listing two surnames, or order by whoever you're closer to — there's no strict rule.
Avoid "and Family." It's vague about who's included; name each person on the inner envelope instead.

Adults-only, handled gracefully

The envelope is the correct place to communicate an adults-only wedding: list only the adults' names, and don't add children's names. Back it up on your wedding website and let close family know personally. Putting "no children" on the invitation itself is considered abrupt — let the addressing do the work.

Return address & RSVP deadline

Put your return address on the back flap of the outer envelope (etiquette traditionally uses the host's address). If you're enclosing a response card with its own envelope, pre-address and stamp it — it noticeably improves your reply rate. For when to mail, see when to send wedding invitations.

Frequently asked questions

Do you write 'and Guest' on the inner or outer envelope?

On the inner envelope. Write the named guest on the outer envelope, and add 'and Guest' on the inner envelope to indicate a plus-one. If you write only the named guest, no plus-one is implied.

How do you address a wedding invitation to a family?

List the parents on the outer envelope (for example, 'Mr. and Mrs. James Bennett') and add the children's first names on the inner envelope ('Mr. and Mrs. Bennett, Emma and Liam'). Naming the children is how they're shown to be invited.

How do you indicate an adults-only wedding on the envelope?

List only the adults' names and leave children's names off. Naming who is invited — and who is not — through the addressing is the polite way to convey adults-only, backed up on your wedding website.

Do you spell out titles and 'and' on wedding envelopes?

On formal envelopes, yes — use Mr., Mrs., Ms., Dr., and write 'and' rather than an ampersand. Casual weddings can relax this, but the formal convention spells everything out.

Do you still need an inner envelope?

No. The inner envelope is traditional but optional. Many modern weddings use a single outer envelope; just make sure the names you write make clear exactly who is invited.
