Step 1: number reverse search for Nummer

General Information on phone Number Reverse Search
Tellows does not offer a complete reverse search that would disclose private information on individuals. Nonetheless, the given information is the cumulation of our users experiences with the respective telephone numbers.

A phone number reverse search, also known as reverse phone lookup or directory is a database of phone numbers and the corresponding details, such as name and address of the customer using this number. Whenever you feel curious about who is calling you, this tool allows you to get detailed information on a certain number and trace back the owner. It thereby also helps you to find out, who harassed you with unsolicited calls.

In some countries however, a reverse lookup is not available or even illegal (in the UK). In others, it is the perfect opportunity to get detailed information. Most phone reverse directories are purpose-built for one country and are often connected to official telephone directories of this country. By searching for official yellow pages, white pages etc., you will quite likely come across a reverse search. Some countries also have a hotline for the purpose of reverse search.

Germany, Austria, Switzerland, USA, Italy, Netherlands, France, Russia, Poland, Czech Republic, India, Denmark, Japan, Norway, Sweden, China, Belgium, Hungary, Argentina, Brazil, Chile, Australia, Indonesia, Singapore, Israel, Colombia, Portugal, Turkey
