Address and geodata
Records for optimum address database maintenance

Anchor Navigation

For address maintenance, a range of reference data is available to you in the “Address and geodata” online service. The “Street directory with sorting data” contains information on street names, house numbers, postcodes and sorting.

Service and features

Address maintenance is an essential precondition for smooth delivery of postal items. Swiss Post knows the correct addresses of private individuals and companies throughout Switzerland. It also continually registers changes of address. As a business customer, you can use this data to maintain your address database.

Street directory with sorting data

By downloading the “Street directory with sorting data”, you obtain all the street, hamlet and plot names as well as the postcodes valid for the addressing of all buildings served by the postal system in Switzerland and the Principality of Liechtenstein. 

You can use the file as a reference for the postal validation of customers’ addresses or as the basis for preliminary sorting of correspondence (letters, newspapers, magazines and catalogues up to 1000 g). This helps ensure that your addressed items reach the right recipients safely and reliably.
