Zettel identifiers are typically created based on the current date and time. By renaming the underlying zettel files, you can provide any sequence of 14 digits.

To make things easier, you must not use zettel identifier that begin with four zeroes (0000).

All zettel provided by an empty zettelstore begin with six zeroes¹. Zettel identifiers of this manual have been chosen to begin with 000010.

However, some external applications may need at least one defined zettel identifier to work properly. Zettel Zettelstore Application Directory (00000999999999) can be used to associate a name to a zettel identifier. For example, if your application is named “app”, you create a metadata key app-zid. Its value is the zettel identifier of the zettel that configures your application.
