Benefits as a Registered tellows User

tellows Premium for the Android app: free for one month!

When you register with tellows for the first time, you get the premium version of the app for free for one month! All you have to do is download the tellows app on your Android phone and log in to the app with your account. Then open the premium menu and confirm the 1-month subscription. You will be redirected to the Play Store. It is a free trial month that turns into a subscription if not canceled before automatic renewal. In the premium version you can not only identify calls, but also block them. You can also use a personal block list that contains all the numbers you rate negatively.

Edit comments
You can edit comments made in the member area or on the number details page.

Creating personal blocking lists
In addition to the community blocking list, which contains current phone numbers that have already been reported by the community, you can immediately add negatively commented numbers to your personal blocking list. If you use tellows products, your block list automatically includes all of your previously rated numbers. You can also link your license code for the blacklist in the member area under “My phone blacklist” . Certain license codes from tellows partners receive an additional year of call protection as a bonus if this is linked to the user account in the member area.

To do this, simply click on “Login” at the top of the tellows page and log in with one of the OpenID accounts mentioned. Only your email address is stored in our system for comparison. After connecting, all you have to do is choose a username. With this function we help to significantly improve the quality and transparency of comments made. More information about: How does OpenID work?

Members area

The members area is available via desktop and mobile view for all registered users. The tellows apps can also be connected to your user account. After logging in, you will find the member area at the top of the page. There you can
  • Access your account settings (change your username and turn off notifications)
  • Manage comments (overview of all comments and editing possible)
  • Manage your personal blacklist (e.g. for the Fritzbox, the tellows apps or the tellows call blocker)

Manage and access your personal block list & tellows API

Numbers with negative comments immediately end up on your personal block list. It is important to log in to the website or link the app to your tellows account. Your personal block list contains all numbers that you have rated yourself (regardless of the ratings of other users) and of course all other phone numbers rated on tellows.

Example: The phone number has a score of 6. You assign a score of 8 when evaluating the number. The number then automatically ends up in your blacklist with a score of 8.

You can use the blacklist with all tellows products , such as the Fritz!Box, the mobile tellows apps, telephone systems (via CSV API) or the call blocker for landlines .

You also have the option of registering on and linking your account with your license code. Phone numbers that have already been rated in your tellows phone book are synchronized in the FRITZ!Box. Numbers that you have blocked via FRITZ!Fon are automatically assigned to your user account. You can find instructions on how to link your tellows account here .

Your personal code to access the blocked list

This code is assigned to your user account. If you are registered on tellows and buy a product in the shop using the same email address, your blacklists are linked to your user account. This means you always receive personalized block lists that take your already rated numbers into account.

If you have already purchased a product in the tellows shop with an email address that does not support Open-ID, then you must first create a new account on You can do so in the member area under “My phone blacklist”Link your license code from the shop to your user account on tellows. Certain license codes from tellows partners receive an additional year of call protection as a bonus if this is linked to the user account in the member area. You can then use this account to rate numbers. If you use the automated blacklist using the CardDAV server for the Fritzbox or the tellows apps, then your self-rated numbers will be taken into account in your blacklists.

For manual downloads of the blocked lists, you can personalize the download link with your user ID. You can find your personal user ID in your member area of tellows. You add this to the download link of the score lists in the shop with the parameter “&userapikey=YOUR_USER_ID”. This must be done manually with each download.


Using the tellows API

All tellows products use the tellows API. By purchasing a tellows API key or the tellows CSV lists, individual queries can be made. Various parameters are available for individualization to refine the output of the results. For example, you will receive results with telephone numbers that correspond to the desired minimum score or have a minimum number of comments.

You can get a detailed insight into the tellows API with all available parameters in our documentation (English): tellows API documentation .

If you are interested in an individual solution for your company, you can join our partner program: tellows API Partnership Program .
