To initiate a lookup, you must enter a valid 10-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 a CNAM record or an approximate location where the phone number was issued. This information will help you narrow down your search.

rLookup acts as your personal assistant that works with you to investigate a phone number by utilizing data sources with millions of records. By unveiling the identify behind a phone number, this app will give you the peace of mind. That way, you can ensure that you are only answering known callers and are not ignoring any important phone calls.

When you lookup 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 tool that can fight unwanted spam and robo callers.
