Swiss directory data

Current Swiss directory data for your business — straight from the providers, updated weekly.

Straight from the source

We obtain Swiss directory data directly from the telecommunications providers. That gives you a reliable, first-hand data foundation.

Continuously updated

Up to 50,000 records are updated every week. Changes to phone numbers, addresses and directory entries are therefore available to you promptly.

Checked and prepared

The delivered data is standardised, checked and structured. This lets you reuse it directly and efficiently in your systems and processes.

Directly through an interface

Through our interface solution, the data can be retrieved automatically and integrated into your existing systems – quickly, reliably and without manual data exchange.

Who our directory data is for

Our Swiss directory data is aimed at businesses and organisations that depend on current, reliable contact data – for example for sales, customer service, data maintenance or automated business processes. It is especially suited to companies that want to regularly check, update or further process phone numbers and address data in their own systems.

How to get the data

Tell us what you need the data for and how you would like to integrate it into your systems. Together we clarify the scope of data, the update rhythm, the desired format and the technical connection. We then put together a solution tailored to your requirements.
