Adressen prüfen und korrigieren mit dem Online API

Um eine hohe Datenqualität bei den Adressdaten zu erreichen, ist es entscheidend, neu eingegebene Adressen direkt bei der Eingabe auf Gültigkeit zu überprüfen. So werden Eingabefehler sofort erkannt und korrigiert - nur gültige Adressen bzw. Postanschriften werden akzeptiert.

Wie funktioniert das API zur Adressprüfung?

Mit unserem Online-API zur Adressvalidierung und Adresskorrektur können Sie die Adressprüfung ganz einfach in eCommerce-Lösungen, Web-Shops, CRM-Systeme oder Content-Management-Systeme (CMS) wie Drupal, Typo3, WordPress oder Joomla integrieren - Code-Beispiele in Javascript, PHP, Java, C#, VB.NET finden Sie weiter unten.

• über die Zustellbarkeit,
• Geo-Koordinaten (Latitude/Longitude) für gültige Adressen,
• Korrekturvorschläge falls die Adresse nicht zustellbar ist
• einheitliche Adressformatierung gemäß der entsprechenden nationalen bzw. internationalen Standards und Richtlinien
