"Company Prefix" is an Android application developed by Erik Sundin. It falls under the category of Social & Communication and is available for free. This app allows users to add a prefix before each call they make. The prefix can be chosen by the user and can be any combination of numbers or characters.

One of the main features of "Company Prefix" is its ability to be used for international calls through calling cards. Users can input a specific number and pin before each number they dial, making it convenient for making international calls.

The app is divided into four sections. In the "CONTACTS" section, users can select or search for a contact they want to call. If the prefix or anonymous call options are enabled in the "SETTINGS" section, the prefix will be automatically added before the dialed number.

The "DIALER" section allows users to manually type the phone number they want to dial. Again, if the prefix or anonymous call options are enabled, the prefix will be automatically included.

The "Favourites" section displays all the contacts that have been marked as favorites on the user's device. Users can easily find a contact by typing their name or surname in the search field.

In the "SETTINGS" section, users can customize various options:

• Insert the prefix that needs to be set before each call
• Enable or disable the suffix, which sends a tone as soon as the call starts to avoid listening to the automatic voice
• Enable or disable the prefix
• Enable or disable anonymous call
