You just got a call on your cell, however you don't know who it was. Is there a way to find out who was on the other line? If the number was already in your phone's address book you would be fine - but we all know it's not quite that simple. If you're in this situation, your best bet is a reverse cellphone lookup. Reverse cellphone lookup sites simplify the proceess of tracing cell phone numbers back to the owners. Do you think it might be possible that your spouse is cheating? Have you seen some unusual calls on your child's phone? Have you received harrassing prank calls from someone you don't know? It really doesn't matter why you need one, a reverse cellphone lookup will be able to track down the info you need. If you're ready to find that caller, all you need to do is select a lookup site to use. You are going to find a bunch of sites out there that will do reverse lookups, however, they are only for landline numbers, like the ones in people's homes. You already know this from experience, but pretty much every home phone number out there is in all sorts of databases, that's why you get all those annoying telemarketing calls. But cell phone numbers do not work the same as home phone numbers. Cell phone numbers are supposed to be considered more private by the phone company, so they don't appear in phonebooks or the central database. That's why sites that actually have good databases chargefees for their servics. They are simply passing along the cost of pulling all that information together and putting it into a searchable format for you to use. After much study and examination, I'm of the opinion that there really is no such thing as a free reverse lookup site. Many sites claim to be free, but in fact only suck in people and then reveal their fees at the last moment. That's not a fair way to do business. Of all the sites I've looked at, I think the ones with simple fee structures are best. The only caveat to that, is that you should pick a site that allows you to check and see if the information you need is in their database before paying. You may also want to consider using a service that offers subscription pricing. Those sites are usually the best value overall. Once you've decided on the site you want to use, the process is really easy and even a little fun. All you do is put in the number you're looking for and in under a minute you'll have exactly what you're looking for, the name and address of the person you're looking for. In addition, there's one service I know of that actually gives you a map to the person's location. It's just not going to get easier than that. To summarize, if you need to find the name of an unknown caller, a reverse cell phone lookup site will give you exactly what you need with speed and accuracy, as long as you choose a reputable site.
