Overview
From 28 December 2026, Booking.com will stop sharing guest phone numbers with channel managers and PMS, including Amenitiz. New Booking.com reservations made from that date will arrive in Amenitiz without a phone number. Everything else in the reservation stays the same.
Until then, guest phone numbers keep arriving in your Booking.com reservations exactly as they do today. You don't need to do anything yet.
This is a Booking.com decision to protect guests from fraudulent WhatsApp and SMS messages. It applies to all connectivity providers worldwide.
It is not a bug or an outage.
From 28 December 2026, you can still find the number in your Booking.com Extranet or the Pulse app, add it to the reservation in Amenitiz, or contact the guest through Booking.com messaging.
Before you start
Only reservations made from 28 December 2026 will arrive without a phone number.
To see a guest's phone number in the Extranet, your Booking.com user needs permission to manage reservations and view guest contact details.
Enter phone numbers with the country code, for example +44 612 345 678. Without it, the Message guest button stays greyed out.

Log in to your Booking.com Extranet.
Go to the Reservations tab.
Search for the reservation number and open the reservation.
In Reservation details, click Show phone number.
In the Booking.com Pulse app, open the reservation from the Bookings tab to see the phone number in the same way.

💡 Tip
Once the phone number is saved, Message guest opens a WhatsApp conversation with the guest. See how to contact guests through WhatsApp.
Contact the guest without a phone number
You don't need the phone number to reach a Booking.com guest:
Booking.com messaging: reply to the guest from Amenitiz. See how to communicate with your Booking.com guests in the Amenitiz inbox.
Masked email address: Booking.com continues to share an email address ending in @guest.booking.com. Emails sent to it reach the guest.
Automated messages: your automated messages to Booking.com guests are sent through Booking.com messaging and are not affected. Automated WhatsApp messages need a phone number.
Important rules
📌 Note
Phone numbers already saved on a reservation stay there, including numbers you add yourself. A modification from Booking.com does not remove them.
💡 Protect your accounts
Activate two-factor authentication on Booking.com, your email and every other service that offers it.
Activate the messaging AllowList in your Extranet so fraudulent links are blocked. If you activate it, add the links you send to guests, for example your online check-in link. Otherwise Booking.com removes them.
Use a different, strong password for each service, and change it if you notice anything unusual.
Report suspicious activity to Booking.com at report.booking.com.
