2. Where the personal data of subscribers to fixed public voice telephony services have been included in a public subscriber directory in conformity with the provisions of Article 11 of Directive 97/66/EC before the national provisions adopted in pursuance of this Directive enter into force, the personal data of such subscribers may remain included in this public directory in its printed or electronic versions, unless subscribers indicate otherwise, after having received complete information about purposes and options in accordance with Article 12 of this Directive.

2. Member States shall ensure that subscribers are given the opportunity, to determine whether their personal data are included in a public directory, and if so, which, to the extent that such data are relevant for the purpose of the directory as determined by the provider of the directory, and to verify, correct or withdraw such data. Not being included in a public subscriber directory, verifying, correcting or withdrawing personal data from it shall be free of charge.

Furthermore, as of 1997, a distinction will be made between basic data, i.e. data and updates which are essential for publishing telephone directories and which directory publishers will thus continue to acquire from Belgacom, and a range of optional supplemental information, which can be acquired from Belgacom or from other market sources.

To the extent that directory services and other information services for subscribers can no longer be regarded as reserved activities, access to raw subscriber data, pure and simple, should be provided on the basis of objective, transparent and non-discriminatory criteria and in accordance with the Community provisions in force, notably with regard to the rules of competition, the principles of Open Network Provision (ONP) and the protection of personal data and individual privacy.

For example, directory databases are used to produce telephone directories and provide directory assistance service.
