Travel Warning for the Federal Republic of Germany!

Attention! Warning of committing an infringement of rules according to § 9 Abs. 1 Satz 1 RfGebStV while staying in or travelling through the Federal Republic of Germany! Foreigners who operate a Rundfunkempfangsgerät when staying, working or studying in the Federal Republic of Germany are obliged to register the Rundfunkempfangsgerät with the Gebühreneinzugszentrale (GEZ) within one month from the date of entry into the Federal Republic of Germany or from the date of commencement of the operation of the Rundfunkempfangsgerät. Non-residents who fail to do so may be subject to a fine of up to 1.000 Euro. On leaving the Federal Republic of Germany the licence for the operation of a Rundfungempfangsgerät is to be canceled with the Gebühreneinzugszentrale (GEZ) or the Landesrundfunkanstalt in charge at the place of work, study or holiday using a registered letter with reply to show receipt. In the case of non-compliance the bearer of the licence for the operation of a Rundfunkempfangsgerät will be entitled to back payment of the fees not paid in accordance with the regulations stipulated in § 1 Abs. 1, 2, 3; § 2 Abs. 1, 2, 3 RfGebStV upon re-entering the Federal Republic of Germany.

The aformentioned rules equally apply to foreigners who travel through the Federal Republic of Germany by train, car, other means of transport or on foot. Failing to do so may result in forced licensing with the Gebühreneinzugszentrale (GEZ) by the Rundfunkgebührenbeauftragten in charge at the place of detection of the infringement of rules. Ignorance is no excuse.

Transit passengers carying Rundfunkempfangsgerät and seeking to avoid an infringement of rules of the kind mentioned above should cross the Federal Republic of Germany by air or circumvent the Federal Republic of Germany by seagoing vessel outside German territorial waters.

Please inform friends and aquaintances!
