Number Identification is an Android application developed by Stefan Mader and Robert Siwy that helps you identify unknown phone numbers. The app is free and falls under the Social & Communication category.

Are you tired of receiving calls or messages from unknown phone numbers and not knowing who they are? Number Identification provides a solution to this problem. With just a few clicks, you can find out who the caller is and add them to your contacts. The app works by allowing you to click on any underlined phone number in any app on your Android device, and it will show you the caller's name and contact information if it is saved in your address book.

Number Identification is easy to use and comes with a Troubleshooting Wizard that can help you reset the default app if you don't get the option to open it after clicking on a number. You can also choose which apps the app works for, and clicking on a number only works if it is underlined. The app may not work for some proprietary SMS applications, but alternative apps like Hangouts or Handcent SMS can be used instead. Note that Number Identification only works for numbers that you have saved in your address book, and does not search any online telephone books.

If you're looking for an app that can help you identify unknown phone numbers, then Number Identification is definitely worth checking out.
