Yes, you can upgrade your second-class BahnCard 100 to a first-class BahnCard 100.

First, order a new BahnCard 100 from a higher category. Then inform BahnCard Service of your wish for an extraordinary termination of your existing BahnCard. Please use the exchange form for this purpose.

The remaining value of the original BahnCard (provided it is at least 15 EUR) will be refunded to the account you specified on the exchange form.

It is not possible to convert a BahnCard 100 from first class to second class, or to a BahnCard Business 25, BahnCard Business 50 or Probe BahnCard.
