Maintain addresses

Anchor Navigation

Around 800,000 people in Switzerland relocate every year. If you do not maintain your addresses, you risk losing 10 percent of your customer base on average, every year. With customer addresses, donor indexes and member lists that are always up to date, you can be sure that your shipments reach the correct recipient. Reactivating existing customers becomes very easy. As part of address maintenance, you receive a detailed statement for each address submitted. You decide which technical access channel you want to use to maintain your addresses.

Our database
A detailed statement for every address

Swiss Post’s address database is unrivalled in Switzerland in terms of quality and quantity. We use our address services to compare our address data with this database. We ensure we are in strict compliance with the legal requirements of data protection. We do not sell, rent or lease any addresses.

As part of address maintenance, we provide a detailed statement for each address submitted. In the process we use our reference data from the street directory, our comprehensive delivery and movers’ files database and from officially published death notices.

Initial and service costs

The costs of address maintenance consist of initial costs (e.g. activation fee) and address maintenance services (address statement, any movers’ addresses, address corrections). You also have free access to various services. Use the many options available to you, and start by performing a free quality analysis on your address data. We provide you with a tailored quotation based on this quality analysis. This tells you how much validating your address data will cost during the next stage.
