RSVP Etiquette: A Complete Guide for Hosts and Guests
The rules of RSVPs made simple: when to reply, how to decline politely, handling plus-ones and kids, and how hosts should ask for (and follow up on) responses.
RSVPs run on a few simple courtesies: reply on time, don’t assume a plus-one, and tell the host the truth. This guide lays out the etiquette for both sides, what guests owe the host, and how hosts can ask for replies (and follow up) gracefully.
The golden rule: reply, and reply on time
Every other rule flows from this one. An RSVP is the host asking, “Can I count on you?” The kind answer, yes or no, is a prompt one. Aim to reply within a few days of receiving the invitation, and never let the deadline pass in silence.
RSVP etiquette for guests
If you’re the one invited, these are the courtesies that matter most:
- Reply by the deadline, or sooner. Don’t wait to see if something better comes up.
- Reply even if it’s a no. Hosts plan around your answer either way.
- Don’t assume a plus-one. Only bring a guest if the invitation names one or says “and guest.”
- Ask before bringing kids. If they’re not named, the event may be adults-only, so check rather than assume.
- Flag dietary needs when you accept, not on the day.
- Honor your yes. Once you’ve accepted, treat it as a commitment, and cancel only for a genuine reason.
How to decline politely
You can always say no. Just do it warmly and promptly, and keep the reason short: “Thank you so much for the invite! Sadly we can’t make it, but we’d love to celebrate soon.” For more lines you can borrow, see our RSVP wording guide.
When can you change your RSVP?
Plans change, and that’s understood. If you said yes and now can’t come, tell the host as soon as you know, ideally before the final headcount is locked in. Flipping from no to yes is trickier: ask rather than assume, since catering and seating may already be set.
RSVP etiquette for hosts
Good replies start with a good ask. Make it easy to say yes (or no):
- Set a clear deadline. “Please RSVP by July 5” gets replies; “let me know” doesn’t.
- Give one way to reply. A single link or number beats three scattered options.
- Be explicit about plus-ones and kids. Address the invitation clearly so no one has to guess.
- Make the deadline realistic. Leave yourself a buffer before you confirm catering or seating.
- Say thank you. A quick acknowledgement makes guests feel their reply landed.
How to follow up on missing RSVPs
A few non-replies are normal; most are “I forgot,” not “no.” A friendly nudge a few days before the deadline is completely acceptable: “Hi! Just closing out numbers for Saturday, hoping you can make it?” Sending one reminder to everyone who hasn’t replied (rather than chasing people one by one) is easiest when you collect RSVPs online.
Plus-ones, kids, and other gray areas
| Situation | The etiquette |
|---|---|
| Invitation names only you | Come solo; no plus-one is implied. |
| Invitation says “and guest” | You may bring one person; tell the host their name when you reply. |
| Kids aren’t mentioned | Assume adults-only and ask before bringing children. |
| You’re running late on deciding | Reply with your best answer by the deadline; update the host if it changes. |
| You need to cancel last-minute | Tell the host directly and as early as possible, with a call or text, not silence. |

- How long do you have to RSVP?
- Reply by the date on the invitation, and ideally within a few days of receiving it. If there’s no deadline, respond as soon as you know your answer. The host needs it to plan.
- Is it rude to not RSVP?
- Yes. Ignoring an RSVP leaves the host unable to plan and is considered impolite. Always reply, even if the answer is no. A quick, gracious decline is perfectly acceptable.
- Can you bring a plus-one if it’s not on the invitation?
- No. Only bring a guest if the invitation names them or says “and guest.” If you’re unsure, ask the host rather than assuming, and the same goes for bringing children.
- Can you change your RSVP after replying?
- You can, but tell the host as soon as possible. Switching from yes to no is fine if you give enough notice; switching from no to yes should be a question, not an assumption, since numbers may already be set.
