I know there have been some issues with the ability to identify postcodes from bookings that are derived from third party distribution channels like booking.com, Expedia, Trivago, wotif.com, etc.
Through our engagement with Expedia, we were able to identify a means by which we might simplify the process of identifying postcodes for cancellations on any of their stable of distribution channels, which include:
Our advice from Expedia is:
Once the hotel is contacted by Expedia regarding a cancellation, you can use the Message Central on our PartnerCentral tool to ask the guest where they booked. The great thing about this tool is that you can set-up a template so that they don’t have the re-type the same question(s) again and again.
If you wish them to, you can also ask for a proof of address (phone bill, driver’s license, etc.) and the guest can reply via an email and attach documents (see example below).
Hopefully this will help you make contact with potential guests that require cancellation due to being located in a restricted postcode.
