Telefon-Nummern auf Gültigkeit prüfen mit dem Online API
Für eine hohe Datenqualität ist es entscheidend, neu eingegebene Kontaktdaten wie Telefon-Nummern direkt bei der Erfassung auf Gültigkeit zu prüfen. So können Eingabefehler unmittelbar erkannt und behoben werden und es ist sichergestellt, dass nur gültige Telefonnummern gespeichert und weiterverarbeitet werden.
Durch die Einbindung unseres APIs zur Rufnummern-Validierung werden alle neu eingegebenen Telefon-Nummern automatisch auf Gültigkeit geprüft. Am besten registrieren Sie sich gleich für einen kostenlosen API-Key und testen unseren Service.
Wie funktioniert das API zur Rufnummer-Prüfung?
Unser Online-API zur Rufnummern-Validierung können Sie ganz einfach in bestehende Websites, eCommerce-Lösungen, Web-Shops, CRM-Systeme oder Content-Management-Systeme (CMS) wie Drupal, Typo3, WordPress oder Joomla integrieren. Wir stellen zu diesem Zweck komplette Plugins und Code-Beispiele in verschiedenen Programmiersprachen bereit. Damit erhalten Sie zu jeder Telefon-Nummer den aktuellen Status sowie nützliche Zusatzinformationen wie die Art des Anschlusses (FIXED_LINE, MOBILE, VOIP), den zugehörigen Ort und die Rufnummer im standardisierten Format gemäß der jeweiligen nationalen bzw. internationalen Richtlinien.
Internationale Telefon-Nummern überprüfen
Mit unserem Service können Sie Rufnummern aus 240 Ländern weltweit auf Gültigkeit überprüfen. Sie erhalten von uns detaillierte Informationen zu jeder einzelnen Telefon-Nummer:
- Status: VALID_CONFIRMED, VALID_UNCONFIRMED oder INVALID
- Anschluss: FIXED_LINE, MOBILE, VOIP etc.
- Ort: Region bzw. Stadt
- Rufnummer im standardisierten Format gemäß der jeweiligen nationalen bzw. internationalen Richtlinien.
Wir garantieren, dass die jeweilige Telefonnummer während des gesamten Prüfprozesses zu keinem Zeitpunkt von uns angerufen wird.
