Airbnb guests want WhatsApp. Here's how to offer it by the rules

It's 23:40, the key box won't open, and your guest has been travelling all day. They won't download an app or wait for an email. They'll message someone, in the app already on their phone. For most of the world, that app is WhatsApp.

This guide covers what guests prefer, what Airbnb allows (the rules change on 20 November 2026), and how to be reachable on WhatsApp during the stay without breaking them.

Guests would rather message than download

WhatsApp has more than 3 billion monthly users, Meta's CEO said in April 2025, and more than 2 billion people use it every day. For a guest from Madrid, São Paulo or Mumbai, it's simply how people talk to each other.

In August and September 2025, the hospitality software company eviivo surveyed 430 travellers worldwide about how they want to communicate with their accommodation:

• 58% preferred SMS, WhatsApp or email links
• 25% wanted to speak to a person, as long as any follow-up was prompt
• 13% preferred an OTA or hotel chain app
• 4% wanted to download a property's own app or scan a QR code

It's a small survey run by a software vendor, so don't lean on the exact numbers. The direction is hard to miss, though: guests want the chat they already have, not something new to install.

What Airbnb allows

This is the part most hosts get wrong, so here are the rules in Airbnb's own words.

Before booking, everything stays on Airbnb. Airbnb's help pages tell guests it is "against Airbnb policy for hosts to ask you to take your booking off of Airbnb or to communicate outside the Airbnb platform through a messaging service (ex: WhatsApp, Facebook, etc.), text, or any platform other than Airbnb prior to booking."

After booking, Airbnb messaging is still the main channel. Airbnb tells hosts that "Airbnb messaging should be the primary way to communicate with guests", and that a guest's phone number only becomes available once the reservation is confirmed.

From 20 November 2026, you can't ask for contact details. For reservations booked on or after that date, "hosts may not solicit personal data at any point during the booking process or stay." That includes phone numbers and email addresses. The old policy let you switch to a chat app if the guest asked for it after booking. That exception is not in the new text.

Optional apps are fine. Required apps are not. The same policy says hosts "can also offer optional apps that facilitate a guest's experience during the stay (e.g. Sonos, Nest, concierge apps)." But they "may not require use of a third-party app or registration on another website to gain entry to a listing or access a critical amenity."

Two practical details:

• Airbnb's system may block a message, or ask you to remove text, when it contains contact information or external links. Check that yours went through.
• In the US and Canada, Airbnb can give both sides a temporary phone number after booking. Those numbers work for calls and SMS, but not for WhatsApp.

How to be on WhatsApp within the rules

Put together, the rules point to one approach: offer, don't collect. You don't ask for the guest's number. You give them a way to reach you on WhatsApp, and they decide whether to use it.

1. Keep everything essential on Airbnb. Check-in steps, the door or key box code, WiFi and house rules belong in your listing and your Airbnb messages, as always. WhatsApp is an extra, never the only way in.
2. Make the offer after booking, and say it's optional. Add a line to your check-in message, such as: "If you'd like quick answers during your stay, you're welcome to message us on WhatsApp." Include the link.
3. Put the same link in the property. A small card by the door or on the fridge catches guests who skipped the message. The QR code is a backup here, not the main way in.
4. Answer fast, or don't offer it. A WhatsApp link sets an expectation. A guest who writes at midnight and hears nothing until morning is worse off than one who was never offered the chat.

The catch: you can't answer WhatsApp all night

Guests message at any hour, and in their own language. You still need to sleep. That gap is what an AI concierge is for.

With HeyConcierge, you put your property link in your Airbnb check-in message. The guest taps it, confirms their booking with their last name and stay dates, and a chat opens on WhatsApp or Telegram. They can also text it by SMS. There's no app to download and no account to create.

The concierge answers from what you've told it about your property, in whatever language the guest writes in, at any hour. When it can't help, it alerts you on WhatsApp, Telegram or SMS, and you can reply to the guest straight from that alert. A guest who is locked out, a leak, no heating or hot water, or anything to do with safety comes straight to you.

The guest opens the chat themselves, so nobody is asked for a phone number, and your check-in details stay on Airbnb where they belong.

Quick checklist

• Nothing off Airbnb before the booking is confirmed
• Never ask the guest for their phone number or email
• Door code, check-in steps and WiFi always in Airbnb as well
• The WhatsApp chat clearly optional
• Someone, or something, answering at night
