Zenodo registers a Digital Object Identifier (DOI) for your record once the record is published. During upload you may pre-reserve a DOI if you e.g. wish to include it into one of the files being uploaded. The pre-reserved DOI is fully internal to Zenodo and is not guaranteed until the record is published. This also means, that we are unfortunately not able to recover a pre-reserved DOI in case you accidentally delete a draft before it's published.
