🧐 Why does this exist?

The German mobile market is complex. There are only 4 physical network operators (Telekom, Vodafone, O2, 1&1), but hundreds of "Resellers" (Aldi Talk, Congstar, sim.de, etc.).

When you want to keep your phone number (Mobile Number Portability / MNP) while switching contracts, the new provider asks for your "Bisheriger Anbieter" (Old Provider).

• Sometimes you need to select the brand name.
• Sometimes you need the parent company (e.g., Drillisch).
• Sometimes you need a specific technical code.

This list maps the Brand Name to the correct Technical Code and the Physical Network.

🌍 For Expats & Foreigners

If you are living in Germany and struggling with the forms, here is a translation of the key terms used in this data:

German Term	English Equivalent	Context
Anbieter	Provider / Carrier	The company sending you the bill.
Anbieterkennung	Porting Code / Short Code	The internal ID used to route your number (e.g., VICT, 1UN1).
Rufnummernmitnahme	Number Porting (MNP)	The process of keeping your number when switching.
Netz	Network	The physical infrastructure (Signal) you are using.
D1	Telekom Network	Generally considered the best coverage.
D2	Vodafone Network
O2 / Telefónica	O2 Network	Very common for budget providers (Drillisch/Aldi).
1&1 5G	1&1 Network	The newest network (roams on Vodafone/O2 where 5G is missing).

⚠️ Common Pitfalls (Read this!)

• Drillisch Brands: If you have a contract with sim.de, handyvertrag.de, winSIM, yourfone, etc., your actual provider for porting is often listed as Drillisch Online GmbH or uses the code VICT.
• WEB.DE / GMX: These are tricky!
  • If you have a standard 24-month contract, you are likely with 1&1 (1UN1).
  • If you have a "FreePhone" or monthly cancelable Flex-Tariff, you are likely with Drillisch (VICT). Check your invoice!
