0170 area code - these networks are behind it

It is no longer possible to say exactly which network the area code 0170 belongs to. Since it has been possible to port the old mobile phone number into the new tariff, the network affiliation of the mobile phone number is no longer clear.

These providers assign the prefix 0170

Originally, the area code 0170 was distributed by German Telekom. In the beginning, it was only allocated to tariffs in the D1 network. However, since the possibility of converting mobile phone numbers to other tariffs, area codes can no longer be traced back to a specific network.

• Cell phone numbers with the prefix 0170 can still be assigned today.
• Numbers with this area code can also come from the subsidiary Congstar.
• Since mobilcom-debitel also markets tariffs in the D1 network, this provider can also assign the prefix 0170.

Find out the network of mobile phone numbers with the area code 0170 - Here's how

If you want to find out which network you are calling on, the easiest way to do this is through your provider's customer service. You can usually find out your tariff details in the online customer center; alternatively, look up your contract documents.

• There are two ways to find out the network of other subscribers with the prefix 0170.
• There are various tools for querying the network of cell phone numbers. These use the "Home Location Register" database.
• For example, go to netz-abfrage.de. Simply enter the relevant mobile phone number there. A few seconds later you will find out which network it is and how often the number has already been ported.
• But be careful, only 10 requests per day are allowed. This is to prevent data misuse and overloading the server.
