Cultural Tip
In German‑speaking countries the house number is a mandatory part of any postal address. Even in small villages, the number (sometimes combined with a street name or a ‘Hauptstraße’ label) is essential for mail delivery, emergency services, and navigation apps. Forgetting it can lead to delayed deliveries or misdirected mail.
