“Perfect! Most useful application in my phone. Thank you!”
”Great app! Tells you who’s calling and gives you the name and address. Love it!”
”Best app I know! I have used before and I use it now... I would recommend this to everyone.”

Who is calling? Imagine answering a call – or receiving a missed call – from a person or a company you have never talked to before.

With CIA – Caller ID App you can immediately see who this caller is. CIA shows the name, address and other details right on your screen, while the phone is still ringing. This means you can prepare yourself properly for the call, or even decide not to take it. Priceless!

CIA gives you Caller ID on all calls, about private persons as well as businesses. Search phone numbers, block spam callers and identify who’s calling, while the call is happening!

More than 45 million people use CIA to identify who calls them. The vast majority of our users are Android users or iPhone users.

We NEVER upload your contact list to make it searchable or public, without your explicit consent to join our crowd sourced “Numbers Sharing Club”.

    It finds businesses that are listed in directory assistance quickly, if they are calling from their main number. Otherwise it comes up unknown. All residential comes up unknown unless they're in my contact list.
