rLookup is a free reverse phone lookup app that helps you find out who is calling you by searching for caller ID of the respective phone number. It works with both cell phone and landline numbers based in the US and Canada. With rLookup, you can lookup phone numbers issued by several carriers including but not limited to AT&T, Verizon, T-Mobile, Metro, Optimum Mobile, and Rogers. For limited numbers, the app is able to give caller's address and other information. To begin your lookup, you must enter a valid digit phone number. When you hit the Lookup button, the app sends a query to a data provider to fetch any available relevant information on that number. In most cases, the fetched information contains the name of the entity. It can be both individual (personal) or a business name. Sometimes, when the name is not available, the app retrieves approximate location where the phone number was issued. This information will help you narrow down your search. rLookup is like your own personal assistant that can work for you to investigate a phone number by utilizing public records and data sources with millions of records, so you can filter out unwanted or unnecessary calls. By unveiling the identify behind a phone number, this app will give you the peace of mind. That way, you can rest assured knowing you are not ignoring any important phone call. When you look up a phone number that you have some information on, you can also report that number from within the app to strengthen the spam database that rLookup maintains. Your report must base on the prior interaction you have had with the caller. Your reports help improve this app further to morph it into a free tool that can fight unwanted spam and robo callers. With such useful features and unlimited potentials, we hope you give rLookup a try and find it handy. If you have any feedback or suggestions to help us improve, please let us know by contacting us.
