How can we support you?
Optimize your address management

Our address and geodata are unrivalled throughout Switzerland in terms of quality and quantity. To express this in figures: almost 13,000 delivery staff collect the latest information every day; up to 450,000 households let us know their relocation information exclusively every year; and 2,200 municipalities collaborate solely with Swiss Post to ascertain street names and house numbers.

Despite this, we do not sell addresses. The data we collect is simply used as a basis for a comparison with your existing addresses or as a solid foundation for address solutions.
