The Caller-ID app by is the internet's first free and real Caller ID service. If somebody called you and you're trying to find out who owns the number, use our app to quickly do a "reverse lookup" and determine who called you.

Now with Maps and improved Geolocation!

Most (if not all) cellular phone carriers do not offer the full caller ID service that exists for landline phones. When someone calls a mobile phone, the cell phone caller ID leaves out the name, only showing the phone number and/or city of the caller. Real landline caller ID shows the number & name of the caller. Finally, a free & real landline caller ID utility exists for the iPhone.

Simply enter the number that called you, and we provide the name ("caller identification") registered to the phone number. Our service works for the entire United States and Canada, and we are adding more countries soon. Our caller identification is accurate information directly received from our telephone company partner. It is the same caller ID you would receive on a landline phone. Note: This App provides Caller ID for approximately 70% of wireless phones and VOIP phones. This is consistent with any other traditional landline caller ID system.

This tool may only be used to research phone numbers that called you. Map areas are approximate.

Seems to work on most instances.

It would be nice if when you did a reverse look up on a cell phone given even business often do have a land line, but may also have cell phones connected to the same company. As it’s frustrating when a private cell calls, no voicemail, n only lists a ruff geolocation over sizable area covered by the cell towers the call was sent from, however, as much as I’d like a name even if first intial, n last name or name of a particular business that’s connected to the billing statement for that particular cell number, not aware of privacy laws would allow the release of such info. As I get a lot of spam calls for some reason, so few years ago, stopped answering, any number not included on my contacts, as I figure if someone’s reaching out for ant legitimate reason then they will-leave a vm, with name, number they can reached at & the nature/purpose of the call. If they call n don’t leave a message, I figure I’m not likely missing out on anything other than a telemarketer soliciting me for one reason or another, n prefer to not have my personal or professional life interrupted by a solicitation, and stick by if no message it’s of no importance to me & I’d rather give my full time& attention to the person(s) presently I’m front of me than to be rude to the person in-front of me just to listen to an elevator speech.

Does exactly what it says it will do

Quick and easy with no crashes so far and have yet to come across a number it couldn't identify. Only annoying thing is that the geolocation lookup is a bit misleading-obviously that only works for landlines which are few and far between these days. Other then that it's the cats pajamas!

Update-I forgot to mention that the design of the app is rather outdated. Although it is very simple to use, the lack of a "back" button is extremely annoying. I hate that I have to do the extra step of pressing geolocate before I can clear out the number I am done with and enter another one for it to look up.

How could such an obvious necessary function have been overlooked? It's not like the rest of the app was so intricate and detailed that the developer was overwhelmed and forgot to add it in there, this app has literally like 2 things it can do. How hard would it have been to add a third function; the back/clear button?!

This app worked well when I first started using it. I love the fact that it's entirely free. I can't remember exactly how any times it worked successfully, but just by guessing I probably received good results around 2 out of 3 numbers I looked up. However, for months now I can't receive any useful result at all. Maybe 1 out of 12 times it works. It doesn't work more than it does. It's so bad now that I've just gave up and stopped using it. Since I first got the app the location has never really done me any good at all. I'm not sure if the app does this for anyone else or not..? But when I search for the location I don't receive an accurate location or description really. For example when I look up a number that is in my state, the map shows an area that covers half of my state.. Doesn't really narrow down the possibilities very much.. The map also doesn't move, zoom in, or anything else that useful for me. Overall I loved it when I first got it (for number look up only) but I'm disappointed in it now.
