Traditionally, a woman's name preceded a man's on an envelope address, and his first and surname were not separated (Jane and John Kelly). Nowadays, the order of the names—whether his name or hers comes first—does not matter and either way is acceptable.
Which name goes first husband or wife?
Both husband and wife use their first names, with the wife's name listed first and the husband's second. It helps to remember the old Southern rule of always keeping the man's first and last name together. And, of course, last names are always written.
Who goes first when addressing an envelope?
The traditional rule that the man's name should come first has changed—now either is appropriate. You can list the person you're closer to first or go alphabetically. If one partner has a distinguished, occupation-related title, their name should be listed first. If both do, go by rank.
