Validity check
Each register extract issued in the dena Biogasregister is provided with a unique register extract number. This number makes it possible to check the authenticity of the corresponding PDF.
All register extracts can also be checked without an account in the Biogasregister:
Check register extract
There are two procedures: Checking using the biogas register extract number and checking using the Biogasregister extract file (PDF). When the extract number is checked, it is displayed whether a corresponding Biogasregister extract has been issued by the dena Biogasregister. This extract can then be downloaded again as a PDF. When checking the extract file in the original output format (PDF), the Biogasregister extract to be checked is temporarily transferred to the Biogasregister and an electronic comparison of the documents is carried out.
