Do you put 'and guest' on wedding invitation envelopes?

Writing "and guest" is standard practice when you do not know the name of the person your guest will bring. It is polite and practical. Put it on the outer envelope only, not on the invitation card itself. If you are using an inner envelope, you can write "and guest" there instead, but with no inner envelope, the outer envelope carries it. If you later learn the guest's name, you can send a separate invitation or a note. Some couples prefer to wait until names are known, but that can delay posting. If you are inviting a whole family, write each child's name or say "and family" if all children are invited. Avoid "and guest" for married couples; use both names. For unmarried partners whose name you know, write both names. If you are unsure whether to allow a guest, it is better to be clear from the start. A guest who sees "and guest" knows they are welcome to bring someone. This saves awkward phone calls and helps your guest plan. Remember, you are not obliged to offer a guest to every single person, but if you do, be consistent.
