The advantages for you

  • Current delivery addresses at all times
  • Protection against fraud
  • 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. The system uses autocomplete for the registration process.


The interface is free of charge. You only invest in connecting it to your system.

Who is this service for & preconditions

The Address verification API interface is designed for companies with large volumes of consignments, who can integrate an interface into their systems and minimize returns, want protection against fraudulent orders and convenience for their customers in the ordering process. A prerequisite is a billing relationship with Swiss Post.
