Physical addresses are an important means of identification even in the digital age. When entering an address, make sure you only enter correct and/or trustworthy addresses into your database. An address that has been verified for accuracy from the outset is well worth the effort in many respects:

• The appropriate form of address is a sign of appreciation.
• Undeliverable items cost money (letter returns);
• Support with downstream IT processes where addresses are accessed;
• Identify fake addresses early on and avoid fraud;
• Avoid any reputational damage.

Swiss Post strictly complies with the legal requirements of data protection. It does not sell, rent or lease any 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.
