How to Address Wedding Invitations: 2026 Etiquette Guide

The rule that covers most envelopes

Write out every adult who is invited, using the name they actually go by. That covers most cases. The envelope has one job: a guest should be able to tell at a glance that they were included. The traditional formats below still look lovely on heavy paper, and nobody will notice if you skip them.

How to address by relationship

• Married couple, same surname: "Mr. and Mrs. James Carter" (traditional) or "Lauren and James Carter" (modern).
• Married couple, different surnames: "Ms. Lauren Patel and Mr. James Carter." Order them alphabetically, or lead with whichever one you know better.
• Same-sex married couple: Both names alphabetical, with whatever titles each prefers: "Ms. Maya Chen and Ms. Sarah Wright."
• Unmarried couple living together: Both names on one line, separated by "and."
• Family with children under 18: Parents on the outer envelope, children listed by name on the inner envelope (or in a separate line on a single envelope).
• Doctor: "Doctor Maya Chen." If both spouses are doctors, either "The Doctors Chen" or both names in full.
• Judge or military officer: Use the rank or title in place of Mr./Ms.
• Single guest with plus-one: "Ms. Maya Chen and guest." If you know the partner's name, use it. It reads much warmer.

What to include inside the invitation

However pared back the design is, five things have to be on it:

• Names of the people getting married.
• Date and time. Spell the time out for a formal suite ("half past five in the evening"), or use numerals for anything modern.
• Venue. Full name and city. The street address belongs on the details card.
• Dress code, or at least a hint of one: "black tie," "garden formal," "festive cocktail."
• RSVP method: a reply card, a QR code or a website.

Guests will also thank you for parking notes, the hotel block, transport times, whether kids are invited and a place to flag dietary needs. All of that goes on a details card so the invitation itself stays clean.

Is it OK to put PM on a wedding invitation?

Yes. Purists still prefer "in the evening" written out, but "5:30 PM" is common now and nobody misreads it. Match whatever the rest of the stationery is doing. Calligraphy reads better with words, a clean modern typeface reads better with numerals.

Common addressing mistakes (and easy fixes)

• Abbreviating "Street" or "Avenue." Spell every word out: Street, Apartment, North, California.
• Forgetting plus-ones on the envelope. If the inner envelope only has one name, that's a one-person invite, and guests will assume the worst.
• Mixing nicknames and formal titles. Pick a register and stay there for the whole guest list.
• Hand-addressing in pencil first. Use a calligrapher, a printer, or a clean labeled envelope. Pencil shows through nice paper.

Frequently asked questions

How do you address a wedding invitation to a family?

Outer envelope to the parents ("Mr. and Mrs. James Carter"). Inner envelope lists everyone invited by name, including children. If you only use one envelope, list each invited person on the address line.

How do you address an invitation to an unmarried couple?

Both names on one line, separated by "and," alphabetical or by who you know best. No need for separate envelopes.

Should I use formal titles like Mr. and Mrs.?

Only if the rest of your stationery is formal. Modern weddings use first and last names without titles, which reads warmer and works for couples of any gender or marital status.

What should be included in a wedding invitation?

Names, date, time, venue, dress code hint, and RSVP method. Push everything else (parking, hotels, transport, dress code detail) onto a separate details card so the main invitation stays elegant.

Is it rude not to include plus-ones?

Not if you're consistent. The rule: every adult in a serious relationship gets a plus-one, every spouse gets named individually, single guests under 25 may be left without one. Whatever rule you pick, apply it to everyone.

Auto-format your guest addresses

Keep the formal name, mailing address and plus-one status for every guest in one list, then print the labels straight from it.
