Solutions for addresses and telephone numbers in the B2B segment

Swisscom Directories AG has been the leading directory manufacturer in Switzerland since 1999 and, under the new directoriesDATA brand, is the preferred partner for providers of directories and similar services. We consider ourselves data agents for all relevant telecoms providers in Switzerland and maintain a comprehensive address database with high-quality address, telephone and contact data. Our employees and digital systems process, update and refine up to 10,000 mutations every day.

Most directories available in Switzerland, such as voice information services (18xy), print and online directories, are based on data from directoriesDATA. With the help of our emergency database, an average of 700 emergency calls per hour are located and the corresponding geo coordinates are transmitted to the responsible emergency organisations. Many companies and institutions use our products to integrate directory data into CRM or telephony solutions and take advantage of our modular customer data

management services (Multisource Services).

In addition to various directory providers, our customers include companies and institutions with large customer bases and regular customer contact. Service providers from the fields of CRM, business information and dialogue marketing also use our services on behalf of their customers.

We provide you with substantial address databases, modular systems and skilled advice from experienced consultants on manual and automated data management, data enhancement and data integration. Get in touch. We look forward to hearing from you.
