People want to identify cell phone calls for a long list of reasons. And chief among them is getting to the bottom of infidelity suspicions. These answers are very easy to obtain, too.

So, is your girlfriend acting just a bit peculiar lately? Is she staying out later than usual? Taking calls into the other room? If so, instead of being the last person to know, you can get possession of her phone when she is not around, jot down the numbers that don't look familiar to you, and do a search on a reverse phone directory.

While this tactic may seem a little underhanded, if you are really being cheated on, do you care? And what it is worth to put your mind at ease? If you are wrong, you can just forget about the whole matter and chalk it up to an overactive imagination. But if you are right, you probably need to take some measures to save what's left of your self-esteem.

Once you have made the decision to research the numbers on her phone, the hard part is done. The easy part is searching the telephone numbers. Here are some quick tips on how to get it done.

Determine Whether a Phone Number is a Landline Number or Cell Phone Number

If some of the phone numbers on your girlfriend's phone are landline numbers, I'd suggest searching them with a free telephone directory. You can find them anywhere on the Internet. Or you can simply enter the number into a search engine and you will soon see a large number of directories that are capable of quickly finding the location and identity of the number you are searching.

If you find out that one or more of the numbers you want to identify are mobile numbers, the best place to these cell phone users is with another kind of phone directory. This phone directory caters to searches of cell phone numbers, unlisted numbers, and other phone numbers not found in free directories.

Yes, you will have to pay a bit of money for each report, but the cost is negligible and you will find out much more personal information that you may even expect about each number you search there.

For about the same amount of money you may drop on the purchase of a compact disc, you can find out the cell phone user's name, existing address, an extensive account of past addresses, wireless carrier name, and, quite often, much more additional personal information. It's a small price to pay to lay your worries and suspicions to rest.

Even better, though, is that you if find you need to do more than a handful of these searches, most directories offer visitors the choice of paying a flat fee for a subscription to their service. This subscription offers unlimited reverse lookups.
