Reverse search of phone numbers: how it works

If you were called from an unknown telephone number, you can use the reverse search to find the name and address of the caller. We show you the best link tips for searching backwards in this practical tip.

Search backwards for landline and mobile numbers on the Internet

The easiest way to identify unknown callers is, of course, to call back. However, if you want to avoid this, you can start a reverse search (also called inverse search) on the following websites. Both landline and mobile phone numbers are listed. In any case, the prerequisite is that the caller has released his telephone number and other contact details and has not contradicted the reverse search.

• The local reverse search
• Klicktel reverse search - the Klicktel phone book including reverse search is also available as purchase software.
• The phone book reverse search
• 11880 inverse search

Inverse search to the phone number for unwanted commercial calls

• Unknown phone numbers often turn out to be advertising calls or opinion research institutes. Their numbers are usually not listed in telephone directories and can therefore hardly be found using a reverse search.
• A good contact point here is the page Rückwaertssuche.org, where you can both research and report the telephone numbers of unauthorized advertising calls.
