65It follows that, where a subscriber has been informed by the undertaking which assigned him a telephone number of the possibility that his personal data may be passed to a third-party undertaking, such as Deutsche Telekom, with a view to being published in a public directory, and where he has consented to the publication of those data in such a directory (in the present case, Deutsche Telekom’s directory), renewed consent is not needed from the subscriber for the passing of those same data to another undertaking which intends to publish a printed or electronic public directory, or to make such directories available for consultation through directory enquiry services, if it is guaranteed that the data in question will not be used for purposes other than those for which the data were collected with a view to their first publication. The consent given under Article 12(2) of the Directive on privacy and electronic communications, by a subscriber who has been duly informed, to the publication of his personal data in a public directory relates to the purpose of that publication and thus extends to any subsequent processing of those data by third-party undertakings active in the market for publicly available directory enquiry services and directories, provided that such processing pursues that same purpose.
