Verifying non-personal address elements:

• Street / no.

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.

We use the very latest data from the street directory covering Switzerland and Liechtenstein for the address assistant.

We provide the “Address assistant” for verifying postal addresses free of charge and with no need for any contractual agreement.

Use the web service to incorporate the address assistant into your IT environment with ease and without any activation fees. If you would like more information about web service connections via REST or SOAP, feel free to consult our technical specifications (“REST address web services” and “SOAP address web services”).
