Digital Services Act

I. EU Monthly Active Recipients

In accordance with Booking.com’s obligations under the EU’s Digital Services Act (DSA), we estimate that the average monthly recipients* of the Booking.com service in the European Union from 1 February 2023 up to and including 31 July 2023, is well above 45 million.

This is only an estimate and is based on the data available to Booking.com at this time, and the limited guidance in the DSA. This estimate is required to be published under the DSA and should not be used for any other purpose. The methodologies used to estimate average monthly recipients as defined in the DSA require significant judgement and design inputs, are subject to data and other limitations, and inherently are subject to statistical variances and uncertainties. This estimate may be revised upwards or downwards as Booking.com refines its approach and in response to the publication of methodology by the European Commission.

Please refer to the Booking Holdings Inc. Investor Relations website for metrics we consider relevant to Booking.com’s business.

* ‘recipient of service’ is defined under the DSA to mean 'any natural or legal person who uses an intermediary service, in particular for the purposes of seeking information and making it accessible'. This requires counting users to whom information was displayed by the Booking.com service, even if that user did not make a transaction.

II. Ads repository

Booking.com has created this ad repository to comply with its DSA obligations, following designation as a Very Large Online Platform ('VLOP'). This repository contains information about advertisements that have been shown on the Booking.com website.
