You're looking at your bill and you see a number you don't recognise or remember calling.
Maybe you're getting prank calls all the time and you'd like to trace who's doing this, if only for your own peace of mind.
The most obvious thing to do of course would be to ring the number.
However people don't always pick-up and often this provides little in the way of help.
Where can you go to then find out who the number belongs to? As of yet the cell phone companies have not provided a public directory for looking up cell numbers.
However despite this there are ways of doing reverse cell number lookups online by entering the number into a form.
The service then tells you straight away if they have the details of that number in their database, the name and address and service provider for example.
This is an increasingly helpful and popular service that lets you know within minutes the details of the cell number.
The downside is that there is usually a small charge for this service, typically less than ten dollars.
However most services usually offer a money back guarantee and run a check that they hold the details before you part with any money.
It may also be that a cell phone number isn't registered which is why it makes sense to do a free reverse cell number lookup first to check.
Many people are still not aware that you can do reverse cell number lookups but it is becoming a more popular service simply out of need.
People need the information on cell phone numbers not only to check their bills but also to determine whether to answer calls and even for personal security.
These services hold large databases of information which are updated regularly.
They provide the answer to one of the stresses of modern life for thousands of people.
