Not long ago, everyone had a landline phone in their home and locating a phone number or address simply required opening the white pages and locating their name. It is often more difficult now that cell phones are widely used and many people do not even have home phones, and if they do their number may be unlisted.

Even with the development of caller ID on most landlines, many numbers may show up without an identifying name and there are ways for callers to prevent their details from showing up. Reverse phone lookup services have responded to these changing times to provide a very valuable service to resourceful phone users.

There are two typical functions for these directories.

Searching for Names

If you are getting calls from someone and only a number is revealed on your ID, or you want to identify cellular phone callers, reverse phone lookup services can assist in finding the name registered to the phone number in question. Just by typing in the phone number you will have access to whoever is initiating the phone calls in question.

People in search of this service 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. Other people may use lookup directories when they want to know a name registered to a landline that is unpublished. If you have a phone number but aren't sure who it belongs to, a reverse phone lookup website can deliver the information.

Locating Addresses

another typical use is to locate an address for someone, whether you know the name of the person or not. Once you gain access to the contact information associated with a particular phone number most services will deliver additional data as well, such as the address of an home phone or the address listed 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 locate a teenager who has run off or is still out long after curfew. If they can find phone numbers from the teenager's belongings or cell phone a lookup directory could quickly reveal addresses and names of locations the child may be at that time.

Other circumstances may be looking for addresses to send out party invitations to your child's friends. If you have the phone number you can find their address and get the invite in the mail without calling or tracking down other busy parents.

Lookup websites can also deliver a connection to other various types of data, such as income brackets and previous addresses, and one site even gives a map with an general pinpoint to the business or home's location.

There is a minor fee for any up to date reverse phone lookup directory, but if your business or personal life requires certain data it is worth the money in the end. The charge is necessary because this sort of information is not simple or completely free to research, pull together, and save, so distributing it on demand to others such as you must also include a charge to account for such operational costs.

There probably will never be a public directory for cell phone numbers, and even if they were compiled it is probable the majority of the numbers would be unpublished just like many landline numbers today. The only way to obtain access to such phone numbers is to give a small charge either to do a one time phone number search or to join a lookup service if you will need to access the directory on a regular basis.
