Where can I get the Hotel Confirmation Number (HCN) / Hotel Reference Booking (HRB)?

Retrieving your Hotel Confirmation Number (HCN) has never been easier!

Once a booking has been successfully confirmed in TravelgateX you may obtain 2 different locators from its logs: the Buyer's locator (client reference) and the Seller's locator (provider reference).

The Seller may also provide a third type of locator, issued by the hotel when it confirms the booking. This is known as the Hotel Confirmation Number (HCN) or Hotel Reference Booking (HRB).

Please note we are only able to provide this code if the Seller returns it in their response, in which case it will be returned in BookRS and BookingQueryRS (Reservation and ReservationRead/List methods). For instance:

Hotel-X Buyers API - Booking Query:

Hotels Buyers API (Legacy) - ReservationRS:


You can check if your Seller returns HCN through their Metadata. These are some of the Sellers that currently return this information in BookRS:

- Allbeds
- GRN Connect
- Ostrovok
- Sabre Hospitality Solutions
- Veturis
- Smyrooms
- MagicRooms
- Expedia


The Seller has confirmed they return HCN information but you are still not receiving it? Please submit a ticket to our Customer Care team for further information.
