How is RSVP written on an invitation?

On a printed invitation, RSVP appears without full stops, as RSVP, not R.S.V.P. It is often followed by a line such as "RSVP by 1 June" or "Kindly RSVP by 1 June". The couple then lists how to reply: a reply card, an email address, a phone number, or a wedding website.

In the UK, it is common to write "RSVP" at the bottom centre or bottom left of the invitation. Some couples write "The favour of a reply is requested" instead, which is a traditional and polite alternative. If the invitation is for a wedding with a separate evening reception, the RSVP line might say "Please reply for both the ceremony and reception" or "Please indicate which events you will attend".

If the couple is using a wedding website, they might write "RSVP online at [website]" or "Please respond via the link on your invitation". If they are having a humanist or religious ceremony, the invitation does not need to mention legal details, but the RSVP line should always include a clear deadline.

If you are designing your own invitations, write RSVP clearly and give a date at least two to three weeks before the wedding. That gives you time to chase any missing replies.
