  • Protection against false information
  • Avoidance of unnecessary returns
  • Easy integration into your web shop

Here’s how it works

With the API Address verification, you reduce the number of items returned as a result of false or fraudulent addresses. It compares personalized addresses (with name), addresses without a name (street, house number, postcode and town only) or parts of an address with Swiss Post’s master data, even while your customer is entering their details in your online shop. The system uses autocomplete for the registration process.

Find out in the practical example how you can use the Swiss Post plug-ins to make a simple purchase an enjoyable experience for your customers.


The services for optimizing your digital commerce are free of charge. You invest only in the connection of the interface to your system.

Who is this service for & preconditions

The API interface Address verification is designed for e-commerce companies with large volumes of consignments (parcel volumes). The interface can be integrated into your online shop systems to assist customers in entering their address and to make the process more convenient for them. By checking that addresses are authentic and up-to-date, incorrect information is identified and returns are minimized. A prerequisite is a billing relationship with Swiss Post.
