Do We Really Need the Reverse Phone Technology? Reverse phone lookup is a technology that enables the public to find the name, address and other contact information of a listed person, by entering a phone number. The service can be compared to that of the yellow pages; the only difference is that we enter a phone number to get the details of a person, while the default process is searching through alphabetically listed names. Presently we can perform this search using our computer, there are several companies which provide this service and display basic information of the listed persons. But it is important to choose the right tool that gives optimum output. Some of them offer free service, while others demand that we pay a small fee. This service is highly beneficial for tracing small companies or organizations that provide varying services. For instance, you can locate address of shop or organization whose services you require, by entering their phone number. Landline numbers are a lot easier to trace than cell phone numbers, as the latter is not listed as widely as landline numbers. Information on a further personal level, such as that of cell phone numbers, are available in a database and is usually accessed by government investigation agencies. This information is unlocked for law enforcement and other such valid emergencies. All mobile phone service providers demand proof of address at the time of purchase of the connection. This information is available in the service provider’s database. It is protected and is unlocked only in cases such as demand from the criminal investigation government organizations. Hence, the reverse phone lookup can perform functions as simple as searching the address of your nearest grocery store, or highly complex ones, such as tracing address of a potentially annoying prank caller with the help of law enforcement organizations.
