Computerized addressing envelopes for wedding and events
It’s important to keep in mind that there are many same-sex couples who still can’t legally marry in their state, but would otherwise be married. In those situations, you can address their invitation as you would for any other married couple (see below).
Married Same-sex Couple
Treat this the same way you would any other married couple:
Write the names on one line with “and” between the names.

If last names are different, you could list them in alphabetical order by last name (though there is no rule that says you must).
If the names are so long that two lines becomes necessary, keep the “and” in there.
Use proper (or preferred) social titles (Mrs. could apply unless Ms. is preferred)
Use first names even when sharing a single surname

When in Doubt, Just Ask
The majority of same-sex couples continue to keep their names and can be addressed as such, whether or not they are legally married. But if you want to be sure, just ask. They will very likely appreciate a polite inquiry rather than an incorrect assumption. And for their part, same-sex couples who marry and change their names can communicate it to everyone easily and naturally through their own wedding stationery, such as ‘at home’ enclosure cards, thank you note cards, and even wedding announcements.
