How to address a wedding invitation envelope
The outer envelope carries the full formal address and full names, since it also has to function as normal mail for the carrier. The inner envelope, used inside a traditional two-envelope invitation, carries a shorter, warmer version, just titles and last names or first names only, and lists only the people actually invited, including any children by name.

What is on this page6 sections
A wedding invitation envelope is not really its own addressing category. It borrows every naming rule from married couples, unmarried couples, and families, and applies it to the most formal occasion most people will ever mail anything for.
What makes it distinct is the optional second envelope, a smaller, unaddressed inner envelope carrying a shorter, warmer version of the same names. It is a genuinely old convention, dating back to when a wedding invitation was hand-delivered rather than mailed, and it survives today mostly as a formal option rather than a requirement.
Step by step
Address the outer envelope formally, in full
Full names, full titles, complete mailing address. This envelope has to work as regular mail, so it follows the same formatting rules as any other formal envelope on this site.
MR AND MRS JAMES HALE1420 N BROADWAYDENVER CO 80202CorrectA formal outer envelope, married couple. Address the inner envelope more casually, with no street address at all
Just the names of who is invited, in a shorter form. Mr. and Mrs. Hale, or first names only for people you know well. The inner envelope does not need a mailing address since it travels inside the outer one.
MR AND MRS HALECorrectThe inner envelope for the same invitation, shorter and warmer. List children by name under their parents on the inner envelope
If children are invited, their names go on the inner envelope under the parents, so it is unambiguous who specifically is included.
Use "and Guest" only when you do not know the guest name
If a single guest is bringing someone and you know that person name, use both names. Reserve "and Guest" for when you genuinely do not know who the plus-one will be.
Follow the same married, unmarried, or family rules as any other formal envelope
A wedding invitation does not have its own separate naming logic. It uses the same married-couple, unmarried-couple, and family addressing rules covered elsewhere on this site, just applied to a more formal occasion.
Quick reference
| Guest situation | Outer envelope | Inner envelope |
|---|---|---|
| Married couple, one last name | Mr. and Mrs. James Hale | Mr. and Mrs. Hale |
| Unmarried couple | Full name, full name, two lines | First names, or Mr. X and Ms. Y |
| Family with children | Parents named, full address | Parents plus each child by name |
| Single guest, known plus-one | Guest full name | Guest name and their plus-one name |
| Single guest, unknown plus-one | Guest full name | Guest name and Guest |
Special cases
The rule above covers most people. Here is what changes for the rest.
Do I really need both an inner and an outer envelope?
No. Two envelopes was standard when wedding invitations were hand-delivered by a footman, who removed the inner envelope and delivered it directly to whichever household member it named, keeping the outer, mail-facing envelope separate. Most couples today use a single envelope, formatted the way the outer envelope traditionally was, which is entirely acceptable and increasingly the norm rather than the exception.
How do I address an invitation to an unmarried couple living at different addresses?
Each person gets their own invitation, mailed to their own address, rather than one invitation addressed to both. This differs from an unmarried couple who share an address, who can typically be addressed on one invitation the same way any unmarried couple sharing a household would be. See the unmarried couple guide for the two-line naming format itself.
What about a same-sex couple, does anything change?
No, the same married or unmarried couple format applies without modification, based on their actual marital status rather than anything else. See the married couple or unmarried couple guide, whichever applies, for the exact naming format.
