PLZ Suche is the fast, fully offline way to find German postal codes. Search by postal code, city, or street name and instantly see the matching areas. No internet connection is needed for the data.

Features:
- Offline search across all German postal codes and cities. Type a ZIP code, a city, or a street and get results in milliseconds.
- Street to ZIP: every postal area includes its streets, so you can find the correct code just from a street name. Combined queries such as Kornblumenring, Uchte or Kornblumenring Uchte work too.
- Interactive map powered by OpenStreetMap with labeled ZIP pins. Tap a pin to open the details.
- Detail view with exact coordinates, copy the postal code to the clipboard, and open the location in your maps app.
- Ten app languages: German, English, French, Spanish, Italian, Dutch, Polish, Turkish, Russian, Ukrainian.
- Light and dark mode, plus selectable accent colors (teal, red, blue) and a high-contrast theme.
- Privacy friendly: no account, no tracking, no collection of personal data. Only map tiles are loaded from OpenStreetMap when you view the map.

Whether you fill out shipping forms, plan deliveries, verify addresses, or simply need the right postal code quickly, PLZ Suche gives you reliable German postal data anywhere, even without a connection.

Data sources: postal code base data from the OpenGeoDB project; street and map data from OpenStreetMap contributors (ODbL).
