It used to be that everyone had a landline phone in their home and finding a phone number or address simply required opening the yellow pages and finding their name. This has become more complicated now that cell phones are widely used and many people do not even have landlines, and if they do their number may be unpublished.
Even with the widespread use of caller ID on most home phones, many numbers may come up without an identifying name and there are ways for callers to prevent their details from showing up. Reverse phone lookup directories have responded to these changing times to provide a very useful service to modern phone users.
There are two typical uses for these directories.
Finding Names
If you are getting calls from someone and only a number comes up on your caller ID, or you want to identify cellular phone callers, reverse phone lookup services can assist in finding the name registered to the number in question. Just by entering the number you will have access to the person who is initiating those bothersome phone calls.
People looking for such services include those who need to identify a number often calling their spouse or teenager's cell phone, since there is no accessible directory for cell phone numbers. Others may use lookup directories when they want to find a name connected to a home phone that is unlisted. If you have a phone number but don't know who it is connected to, a reverse phone lookup directory can help.
Searching for Addresses
The other common purpose is to identify an address for someone, whether you know the name of the person or not. Once you plug into the contact information associated with a specific number most directories will deliver other sorts of data as well, which includes the address of an home phone or an address connected to a cell phone number.
This may not be a common need for most people, but it does have its uses in quite a few situations. Such as a parent desperate to find a teenager who has run away or is still out long after curfew. If they can get access to numbers from the teenager's bedroom or cell phone a lookup directory could quickly uncover addresses as well as names of places the teenager may be located.
Other circumstances may be searching for addresses to mail out party invitations to your child's friends. If you have their phone number you can get their address and easily deliver the invite without calling and tracking down other busy people.
These services can also deliver a connection to other various types of data, like income brackets or previous addresses, and one site even gives a map with an general pinpoint of where the home or business is located.
There will be a nominal price for any up to date reverse phone lookup directory, but if your business or personal situation requires accurate data it is money well spent in the end. The fee is necessary because this variety of information is not easy or free to research, collect, and store, so distributing it on demand to people such as you must also collect a charge to account for such working expenditures.
There more than likely will never be a public directory for cellular numbers, and even if there were it is probable a lot of the numbers would be unlisted as is the case with many home phone numbers today. The best way to obtain access to such numbers is to give a minor fee either to complete a one time phone number lookup or to join a lookup directory if you will be using the service on a regular basis.
